Firebase initializeApp回调

我经常依赖Firebase在我的应用程序正常运行之前进行初始化。Firebase

initializeApp

函数似乎没有回调指示其初始化时间。我认为

initializeApp

是一个异步函数，如果是这样，我如何设置回调以指示它在继续之前已初始化？

我也有同样的问题。您可以使用Firebase REST API作为替代。它几乎拥有所有的功能。例如获取访问令牌、登录、注册等指南

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

亲爱的Cody Gray您是一名业余开发人员。 实际上，这不是库或工具。我只是要求您使用Firebase Rest Api而不是web Api。它是firebase的标准RESTAPI

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

Firebase同时提供web api和rest api。 可以在请求完成或收到响应时调用RESTAPI和回调函数

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

我提供的链接是firbase rest api的完整rest api文档

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

现在您使用的web api是有限的

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

请通过服务器端脚本从firebase使用此rest api。 例如，您可以使用php curl

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

$data=array（“电子邮件”=>U请求['email']，“密码”=>U请求['pass']，“returnSecureToken”=>true”）
$data\u string=json\u encode（$data）

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

因此，您可以像login.php一样保存此脚本

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

然后通过javascipt、jquery、ajax或语言发出http请求。在http响应上，只需在身份验证、注册或登录之后执行您想要执行的任务

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

我发给你的指南中有所有api的列表。你可以根据需要使用

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

同样，这不是工具或库。这是标准的firebase rest api

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

我也有同样的问题。您可以使用Firebase REST API作为替代。它几乎拥有所有的功能。例如获取访问令牌、登录、注册等指南

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);

    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

亲爱的Cody Gray您是一名业余开发人员。 实际上，这不是库或工具。我只是要求您使用Firebase Rest Api而不是web Api。它是firebase的标准RESTAPI

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

Firebase同时提供web api和rest api。 可以在请求完成或收到响应时调用RESTAPI和回调函数

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

我提供的链接是firbase rest api的完整rest api文档

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

现在您使用的web api是有限的

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

请通过服务器端脚本从firebase使用此rest api。 例如，您可以使用php curl

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

$data=array（“电子邮件”=>U请求['email']，“密码”=>U请求['pass']，“returnSecureToken”=>true”）
$data\u string=json\u encode（$data）

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

因此，您可以像login.php一样保存此脚本

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

然后通过javascipt、jquery、ajax或语言发出http请求。在http响应上，只需在身份验证、注册或登录之后执行您想要执行的任务

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

我发给你的指南中有所有api的列表。你可以根据需要使用

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

同样，这不是工具或库。这是标准的firebase rest api

$ch = curl_init('https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=AIzaSyB1fIfESmR6DAUJ24X70ch2xEpi9BfF_sE');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);

firebase initializeApp（）返回一个非空的firebase.app.app，它是已初始化的应用程序。所以您可以使用if（firebase.app（））检查您的应用程序是否已初始化，然后proceedRun遇到相同的问题。你解决了这个问题吗？当我将react应用程序的初始化设置为超时时，一切正常。假设initializeApp是一个异步函数。但是如何处理呢？initializeApp是同步的，另请参见以下答案：firebase initializeApp（）返回一个非空的firebase.app.app，它是已初始化的应用程序。所以您可以使用if（firebase.app（））检查您的应用程序是否已初始化，然后proceedRun遇到相同的问题。你解决了这个问题吗？当我将react应用程序的初始化设置为超时时，一切正常。假设initializeApp是一个异步函数。但是如何处理呢？initializeApp是同步的，请参见以下答案：
