Download Google Drive API下载文件，http响应代码200，但响应库为空

对不起，如果这是一个愚蠢的问题，但我是新来的，我不知道如何遵循

我已经在我们的服务器上用php实现了对Google drive的支持，这为我们在Android和IOs上的应用提供了支持，我们可以将文件上传到Google drive或删除它们，没有任何问题。当我们下载文件时，看起来httpResponseCode是正确的，responseHeader也是正确的，但ResponseBook是空的

我把谷歌硬盘服务器的回复放在这里，以防有人知道。谢谢

现在我使用的代码是：

   public function GetFile($fileId) {
     $fileVars = null;
     try {
       /*
        * Retrieve metadata for the file specified by $fileId.
        */
       $file = $this->service->files->get($fileId);
       $fileVars = get_object_vars($file);

       /*
        * Retrieve the file's content using download URL specified in metadata.
        */
       $downloadUrl = $file->getDownloadUrl();
       error_log('Download URL file from Drive: ' . $downloadUrl);
       if ($downloadUrl) {
         $request = new apiHttpRequest($downloadUrl, 'GET', null, null);
         $httpRequest = apiClient::$io->authenticatedRequest($request);
         error_log(print_r($httpRequest, 1));

         if ($httpRequest->getResponseHttpCode() == 200) {
           $content = $httpRequest->getResponseBody();
           $fileVars['content'] = $content?($content):'';
         } else {
           // An error occurred.
           return null;
         }
       } else {
         // The file doesn't have any content stored on Drive.
         return null;
       }

     } catch (apiServiceException $e) {
       /*
        * Log error and re-throw
        */
       error_log('Error retrieving file from Drive: ' . $e->getMessage());
       throw $e;
     }
     return json_encode($fileVars);
    }

您可以尝试使用cURL手动执行相同的请求吗？这将告诉我们PHP端或API端是否存在问题。请求应该是这样的：curl-H'Authorization:Bearer…谢谢Nivco，我相信我刚刚发现了问题，我猜我是php新手，旧的google代码示例组合不起作用，但对google有利的是，get文件的新代码示例更好，更有效。很高兴看到它工作，但我感觉很糟糕，因为正如我在第一句话中所说的，这只是二进制编码和字符串之间的一个愚蠢问题。非常感谢您回复我的电子邮件并尽力提供帮助。不客气。我很高兴你有它的工作！
