【问题描述】:
我正在尝试使用 PHP 和 CURL 连接到 Microsoft Dynamics API,以便我可以从 CRM 读取客户端数据。 API指南可以在这里找到: https://msdn.microsoft.com/en-gb/library/mt593051.aspx
我已进入 Azure 门户并设置了一个新应用程序,它为我提供了要使用的凭据(客户端 ID、机密等)和 url 端点。使用这些凭据,我能够成功连接到 CRM 并检索不记名访问令牌,但我无法进一步了解。
当我尝试使用令牌返回数据时,我收到以下错误消息:
HTTP 错误 401 - 未经授权:访问被拒绝
我的假设是我必须正确传递令牌?
我的代码如下。
<?php
// Step 1 - Use the credentials supplied by CRM to get an access token (this bit works okay)
$credentials = array(
'grant_type'=>'client_credentials',
'username'=>'xxxxxxxx',
'password'=>'xxxxxxxx',
'client_id'=>'xxxxxxxxxxxx',
'client_secret'=>'xxxxxxxxxx',
);
$urlSafeCredentials = http_build_query($credentials);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'https://login.microsoftonline.com/xxxxxxxxxxxxxx/oauth2/token');
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $urlSafeCredentials);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
$response = curl_exec($ch);
$result = json_decode($response);
curl_close($ch);
// A BEARER access token is successfully returned
$token = $result->access_token;
// Step 2 - Use the access token to request data from the CRM (this bit fails with HTTP Error 401 - Unauthorized: Access is denied)
$ch = curl_init('https://clientspecificurl.crm4.dynamics.com/api/data/v8.1/accounts');
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: application/json', 'Content-Type: application/x-www-form-urlencoded','Authorization: Bearer '.$token));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$response = curl_exec($ch);
curl_close($ch);
print_r($response); // 401 Unauthorized ?!
?>
据我所知,后端无需配置任何其他内容,我们将不胜感激。
