Facebook登录JavaScript示例
//使用来自FB.getLoginStatus()的结果调用此函数。
函数statusChangeCallback(响应){
log('statusChangeCallback');
控制台日志(响应);
//响应对象返回的状态字段允许
//应用程序知道此人的当前登录状态。
//响应对象的完整文档可以在文档中找到
//对于FB.getLoginStatus()。
如果(response.status===“已连接”){
//登录你的应用程序和Facebook。
AWS.config.region='eu-west-1';//地区
AWS.config.credentials=新的AWS.CognitoIdentityCredentials({
IdentityPoolId:'eu-west-1:xxxxxxxx-xxxx-xxxx-xxxx-XXXXXXXXXXXXXX',
登录:{
'graph.facebook.com':response.authResponse.accessToken
}
});
console.log(AWS.config);
testAPI();
}else if(response.status===“未授权”){
//此人已登录Facebook,但未登录您的应用程序。
document.getElementById('status')。innerHTML='Please log'+
“进入此应用程序。”;
}否则{
//此人未登录Facebook,因此我们不确定是否
//他们是否登录到此应用程序。
document.getElementById('status')。innerHTML='Please log'+
“进入Facebook。”;
}
}
//当某人完成登录时调用此函数
//按钮。请参见示例中附加到它的onlogin处理程序
//代码如下。
函数checkLoginState(){
FB.getLoginStatus(函数(响应){
状态更改回调(响应);
});
}
window.fbAsyninit=函数(){
FB.init({
appId:'xxxxxxxxxxxxx',
cookie:true,//启用cookie以允许服务器访问
//会议
xfbml:true,//解析此页面上的社交插件
版本:“v2.5”//使用图形api版本2.5
});
//现在我们已经初始化了JavaScript SDK,我们调用
//getLoginStatus()。此函数用于获取
//访问此页面的人,可以将三种状态之一返回到
//您提供的回调。它们可以是:
//
//1.登录到您的应用程序(“已连接”)
//2.登录Facebook,但不登录你的应用程序(“未授权”)
//3.未登录Facebook,无法判断是否已登录
//你的应用与否。
//
//这三种情况在回调函数中处理。
FB.getLoginStatus(函数(响应){
状态更改回调(响应);
});
};
//异步加载SDK
(功能(d、s、id){
var js,fjs=d.getElementsByTagName[0];
if(d.getElementById(id))返回;
js=d.createElement;js.id=id;
js.src=“//connect.facebook.net/en_US/sdk.js”;
fjs.parentNode.insertBefore(js,fjs);
}(文档“脚本”、“facebook jssdk”);
//在这里,我们在登录完成后运行一个非常简单的Graph API测试
//成功。请参阅statusChangeCallback()了解何时进行此调用。
函数testAPI(){
log('欢迎!获取您的信息…);
FB.api('/me',函数(响应){
console.log('successfulllogin for:'+response.name);
document.getElementById('status').innerHTML=
'感谢您登录,'+response.name+'!';
});
}
但是,当我在Cognito控制台中检查identity browser时,我没有看到任何用户通过FaceBook登录。在更新凭据参数后,您实际上需要从服务获取凭据
AWS.config.credentials.get(函数(err){…})代码>是一种方法
