download - Google Drive API downloadFile getIo 错误

Question

我想创建一个 gDrive 应用程序。我可以得到下载网址(如字符串'https://doc-0k-68-docs.googleusercontent.com/docs/securesc/gf6salc3nfs5me1dnqgnp4crl90gg593/21kfelc8h3l1qvkgskqacnee2pqjt5es/1343484000000/14678698184812381901/1467 8698184812381901/0B95t2gVGbZ61Sk0yNlY5TTZObUU?h=16653014193614665626&e=下载&gd=true'(长度=251) )

但我无法通过此链接下载。我想，必须有一些授权。

我尝试这个功能，我采取here

function downloadFile($service, $file) {
  $downloadUrl = $file->getDownloadUrl();
  if ($downloadUrl) {
    $request = new apiHttpRequest($downloadUrl, 'GET', null, null);
    $httpRequest = $service->getIo()->authenticatedRequest($request);
    if ($httpRequest->getResponseHttpCode() == 200) {
      return $httpRequest->getResponseBody();
    } else {
      // An error occurred.
      return null;
    }
  } else {
    // The file doesn't have any content stored on Drive.
    return null;
  }
}

我犯了一个错误

调用...中未定义的方法 apiDriveService::getIo()

请帮助我。我到处都找不到。

其实我只是想喜欢这个网站。

但是，我只是在我的网站中自动创建每个链接。

Answer 1

我安装了最新的 PHP 客户端库，但上述建议的编辑均不起作用。

原始代码

 $httpRequest = $service->getIo()->authenticatedRequest($request);
 Fatal error: Call to undefined method Google_Service_Drive::getIo() 

第一个建议的更改:

$httpRequest = apiClient::$io->authenticatedRequest($request);
Fatal error: Class 'apiClient' not found in ...../Drive/auth.php

第二个建议更改:

$httpRequest = Google_Client::$io->authenticatedRequest($request);
Fatal error: Cannot access private property Google_Client::$io in .../Drive/auth.php

我发现“authenticatedRequest($request);”在-src/Google/Auth/OAuth2.php

 public function authenticatedRequest(Google_Http_Request $request)
  {
    $request = $this->sign($request);
    return $this->client->getIo()->makeRequest($request);
  }

所以我将调用更改为:

 $httpRequest = Google_Auth_OAuth2::authenticatedRequest($request);

但它返回错误:

fatal error :不在对象上下文中使用 $this

终于找到了解决方案，这是完整的代码:

function downloadFile($service, $downloadUrl,$client) {

if ($downloadUrl) {
  $request = new Google_Http_Request($downloadUrl, 'GET', null, null);

  $SignhttpRequest = $client->getAuth()->sign($request);
  $httpRequest = $client->getIo()->makeRequest($SignhttpRequest);

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