【问题描述】：

我正在尝试获取我的广告系列的每日费用。我使用这个文档https://developers.google.com/adwords/api/docs/guides/reporting

我也在使用 php 和 Yii2。我有：

客户客户 ID

客户编号
访问令牌
client_secret

刷新令牌

当我获得广告系列名称和 ID 时，那些 client Customer Id,client id,client_secret 就足够了，我获得的广告系列没有任何问题，但是当我尝试获取报告时，出现错误

也许我在 curl 错误的情况下发出了发布请求，因为我能够毫无错误地获得广告系列。这是我的代码

$ch = curl_init();

        curl_setopt($ch, CURLOPT_URL,"http://adwords.google.com/api/adwords/reportdownload/v201702");
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch,CURLOPT_HEADER,1);

$XML= <<<XML

XML;

$headers = array("Content-Type:multipart/form-data",
 "Authorization"=> "Bearer my_access_token",
  "developerToken" => "my_developer_token",
 "clientCustomerId"=> 111-111-1111, // test account

); 

$postfields = array("__rdxml" =>$XML );
        curl_setopt($ch, CURLOPT_HTTPHEADER , $headers);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);


 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

        $server_output = curl_exec ($ch);
 echo "<pre>";
var_dump($server_output);
echo "</pre>";
        curl_close ($ch);

【解决方案1】：

原来我生成了错误的访问令牌。当我按照此处https://developers.google.com/identity/protocols/OAuth2WebServer#incrementalAuth 的描述生成它时一切顺利。
