adwords api报告缺少客户端信息

Question

我想知道我竞选活动的日常费用。我用这个留档https://developers.google.com/adwords/api/docs/guides/reporting

我也在使用php和Yii2。我有：

客户ID

客户端id
访问令牌
客户端密钥

刷新令牌

当我得到活动名称和id，这些客户客户ID，客户ID，client_secret就足够了，我得到活动没有任何问题，但当我试图得到一个报告，有错误

也许我用curl发帖子的请求是错误的，因为我可以毫无错误地获得活动。这是我的密码

$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

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

); 

$postfields = array("__rdxml" =>$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);

Answer 1

结果是我生成了错误的访问令牌。当我像这里描述的那样生成它时https://developers.google.com/identity/protocols/OAuth2WebServer#incrementalAuth一切顺利。
