与 ASP.NET 的 HttpWebResponse GetResponse 函数等效的 PHP cURL 是什么？

Question

我正在处理这个not-so-great ASAP Connected 文档。它是为 .NET 编写的，但我正在用 PHP 为客户端创建一个 WordPress 插件。

为了获得授权，它提供了这个 sn-p：

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://stagingapi.asapconnected.com/api/login");
request.Headers.Add(HttpRequestHeader.Authorization, "user=username&organizationId=id&password=password&apiKey=apikey");
request.Accept = "application/json";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
string accessToken = response.Headers["asap_accesstoken"];

在我的插件中，我正在尝试这样做：

$request_url = 'https://stagingapi.asapconnected.com/api/login';
$headers = array(
    //Accept or Content type
    'Accept: application/json',
    //Authorisation
    'Authorization: ' . http_build_query(array(
        'user' => ASAPCONNECTED_USERNAME,
        'password' => ASAPCONNECTED_PASSWORD,
        'organizationId' => ASAPCONNECTED_ORGANIZATION_ID,
        'apiKey' => ASAPCONNECTED_API_KEY
)));
$curl = curl_init($request_url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); //Return response as string instead of display
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); //Ignore any SSL errors
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers); //Specify our header
curl_setopt($curl, CURLOPT_HTTPGET, true); //Specify that this is a GET request
$response = curl_exec($curl); //Execute cURL and collect the response
$curl_info = curl_getinfo($curl); //Retrieve it's info
$curl_error = curl_error($curl); //Retrieve it's error
curl_close($curl); //Close the cURL
if ($curl_error || !$response) {
    if ($curl_error) {
        //An error occurred requesting authorisation from the API!
    }
    if (!$response) {
        //The response was empty when requesting authorisation from the API!
    }
} else {
    //The API authorisation request was a success! Do stuff...
}

所以我认为“GetResponse”就像一个 GET 请求，并且文档和它的 sn-p 非常清楚地将 API 凭据放在“授权”标头中。但是，我得到的响应是空的！它不返回任何错误。当我记录$curl_info 变量时，它会输出这个（省略了一些数据）：

有什么想法吗？

@Barmar 指出，在 ASAP Connected API 的 the documentation 中，访问令牌位于响应的标头中。我只需要添加 curl_setopt($curl, CURLOPT_HEADER, true); 以在响应中包含这些标头，因此我在 PHP 中的请求如下所示：

$request_url = 'https://stagingapi.asapconnected.com/api/login';
$headers = array(
    //Accept or Content type
    'Accept: application/json',
    //Authorisation
    'Authorization: ' . http_build_query(array(
        'user' => ASAPCONNECTED_USERNAME,
        'password' => ASAPCONNECTED_PASSWORD,
        'organizationId' => ASAPCONNECTED_ORGANIZATION_ID,
        'apiKey' => ASAPCONNECTED_API_KEY
)));
$curl = curl_init($request_url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); //Return response as string instead of display
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); //Ignore any SSL errors
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers); //Specify our header
curl_setopt($curl, CURLOPT_HEADER, true);//Include headers in response
curl_setopt($curl, CURLOPT_HTTPGET, true); //Specify that this is a GET request
$response = curl_exec($curl); //Execute cURL and collect the response
$curl_info = curl_getinfo($curl); //Retrieve it's info
$curl_error = curl_error($curl); //Retrieve it's error
curl_close($curl); //Close the cURL
if ($curl_error || !$response) {
    if ($curl_error) {
        //An error occurred requesting authorisation from the API!
    }
    if (!$response) {
        //The response was empty when requesting authorisation from the API!
    }
} else {
    //The API authorisation request was a success! Do stuff...
}

再次感谢@Barmar！

请注意：他们的支持团队似乎对他们自己的产品并不了解。所以在询问 API 凭证时，要非常具体。我第一次问的时候，他们给了我一个临时访问令牌，有效期超过一年。我第二次问，他们给了我不正确的凭据。第三次是魅力。不幸的是，您必须向他们开一张票以获取这些凭据，因为它们在任何地方的管理仪表板中都不可用。

如果其他人正在使用 PHP 使用此 API 并且有任何问题，我很乐意提供帮助，因为我也在此过程中。这个项目结束后，我什至可能会写一两个教程。
