设置GET-cURL请求（PHP）

我对如何向正在使用的API设置cURL请求有点困惑。具体来说，这是一个叫做ShipStation的履行中心。我过去做过很多cURL请求，但现在我正试图找出如何设置“MERGE”cURL请求，而不是“GET”cURL请求，等等。您可以在这里看到“GET”头以从API获取信息：

http://api.shipstation.com/Order-Resource.ashx#Reading_an_Order_5

然后更新/合并数据：

http://api.shipstation.com/Order-Resource.ashx#Updating_an_Order_6

不过，每次尝试发送请求时，我都会发现curl_setopt:supplied参数不是有效的curl句柄，在几行上都有资源错误。我最初尝试复制数据并尝试将其作为标头发送：

$header .= "GET https://data.shipstation.com/1.3/Orders(128714) HTTP/1.1";
$header .= "User-Agent: Microsoft ADO.NET Data Services";
$header .= "Accept-Charset: UTF-8";
$header .= "DataServiceVersion: 1.0;NetFx";
$header .= "MaxDataServiceVersion: 2.0;NetFx";
$header .= "Accept: application/atom+xml,application/xml";
$header .= "Host: data.shipstation.com";

//Send request
$curlConn = curl_init(); 
curl_setopt($curlConn,CURLOPT_USERPWD,'myusername:mypassword'); 
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $header);
curl_setopt($curlConn,CURLOPT_RETURNTRANSFER,1); 
$ret = curl_exec($curlConn); 
curl_close($curlConn);

我会将用户名和密码更新到我的凭据中，因为您需要它才能登录到此API。我基本上是照着原样复制标题，但它不起作用。我还将“CURLOPT_CUSTOMREQUEST”更新为“CURLOPT_HTTPHEADER”，但两者都给出了错误

我不明白我哪里出错了，我也不知道如何才能返回更详细的错误消息，以便我能够找到代码问题的根源，因为我只得到了提供的参数错误

谢谢你的帮助

编辑 也许我的做法不对？我如何发送“合并”请求，如上面链接中的文档所示。我不知道如何获取他们提供的标题信息，并将其转换为对API的请求。

请尝试以下方法：

$end = "\r\n";  
$header .= "GET https://data.shipstation.com/1.3/Orders(128714) HTTP/1.1" . $end;
$header .= "User-Agent: Microsoft ADO.NET Data Services"  . $end;
$header .= "Accept-Charset: UTF-8" . $end;
$header .= "DataServiceVersion: 1.0;NetFx" . $end;
$header .= "MaxDataServiceVersion: 2.0;NetFx" . $end;
$header .= "Accept: application/atom+xml,application/xml" . $end;
$header .= "Host: data.shipstation.com" . $end;

//Send request
$curlConn = curl_init(); 
curl_setopt($curlConn,CURLOPT_USERPWD,'myusername:mypassword'); 
curl_setopt($curlConn, CURLOPT_CUSTOMREQUEST, $header);
curl_setopt($curlConn,CURLOPT_RETURNTRANSFER,1); 
$ret = curl_exec($curlConn); 
curl_close($curlConn);

请试试这个：

$username = "YOUR API KEY";
$password = "YOUR API SECRET";

$endpoint = "https://ssapi.shipstation.com";

$ch = curl_init();
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_HTTPHEADER, array ("
    Content-Type: application/json"
    ));

create_order($ch, $endpoint);

function create_order($ch, $endpoint) {
    curl_setopt($ch, CURLOPT_URL, $endpoint . "/orders/createorder");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_POST, TRUE);

curl_setopt($ch, CURLOPT_POSTFIELDS, "{

这不再抛出错误，但我也不会得到API的响应。我会再看一看，然后再打给你。这可能已经达到了目的。所以当我使用它并执行var_dump$ret时，我会收到一个boolfalse响应。这一定意味着它没有正确连接，即使我没有从API获得错误响应？这意味着连接失败
