PHP 检索 POST 结果

Question

我正在尝试为“Exact Online”创建一个应用程序，但我在 OAuth 安全身份验证方面遇到了一点问题

https://developers.exactonline.com/#OAuth_Tutorial.html%3FTocPath%3DAuthentication%7C_____2

在发出我的第一个身份验证请求并登录后，我收到了一个代码。 使用此代码，我可以获得一个用于进行 api 调用的令牌。

if (!empty($_GET["code"])){
$code = $_GET["code"];

到目前为止，获取代码有效。但是当我尝试发出新请求（针对令牌）时，我没有收到任何响应数据。 我的代码如下：

$data = array(
    'code' => $code,
    'redirect_uri' => 'http://****/asdf2.php',
    'grant_type' => 'authorization_code',
    'client_id' => '******-****-****-******-*****',
    'client_secret' => '*********'
);
// Create map with request parameters

// Build Http query using params
$query = http_build_query ($data);

// Create Http context details
$contextData = array ( 
                'method' => 'POST',
                'header' => "Connection: close\r\n".
                            "Content-Length: ".strlen($query)."\r\n",
                'content'=> $query );

// Create context resource for our request
$context = stream_context_create (array ( 'http' => $contextData ));

    // Read page rendered as result of your POST request
$result =  file_get_contents (
                  'https://start.exactonline.nl/api/oauth2/token',  // page url
                  false,
                  $context);

// Server response is now stored in $result variable so you can process it
if (!empty($result)){
echo "success"; 
}else{
echo "no result";
}
}else { 
echo "error";
}

$result 总是空的，这可能是什么问题。我已经多次检查了我的 client_id 和 secret。

改成cUrl后还是不行：

$result = get_oauth2_token($code); 

// Server response is now stored in $result variable so you can process it
if (!empty($result)){
echo "success";
}else{
echo "no result";
}
}else { 
echo "error";
}

/*
Function
*/

function get_oauth2_token($code) {

global $client_id;
global $client_secret;
global $redirect_uri;

$oauth2token_url = "https://start.exactonline.nl/api/oauth2/token";
$clienttoken_post = array(
    'code' => $code,
    'redirect_uri' => 'http://*****/asdf2.php',
    'grant_type' => 'authorization_code',
    'client_id' => '{*******}',
    'client_secret' => '******'
);

$curl = curl_init($oauth2token_url);

curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $clienttoken_post);
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

$json_response = curl_exec($curl);
curl_close($curl);

$authObj = json_decode($json_response);

if (isset($authObj->refresh_token)){
    //refresh token only granted on first authorization for offline access
    //save to db for future use (db saving not included in example)
    global $refreshToken;
    $refreshToken = $authObj->refresh_token;
}

$accessToken = $authObj->access_token;
return $accessToken;
}

文档显示client_id 应该在花括号内。所以我认为应该是：

'client_id' => '{******-****-****-******-*****}',
