Google Drive API httpRequest 下载文件对话框

Question

我是 PHP 新手，我一直在使用 Google Drive PHP API。

这是我的代码：

function downloadFile1($service,$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;
 }
}

到目前为止一切顺利。但我想得到一个对话框来将文件保存到我的电脑（当我得到返回结果时）。我怎么能得到它？

[如果我执行一个

$content = $httpRequest->getResponseBody();
print_r($content);]

我可以在网页中看到文件的内容，但我想下载它！]

提前致谢！

不要使用 PHP 将文件下载到服务器，而是在页面上向用户显示指向文件webContentLink 的锚点。单击该链接会将文件下载到用户的计算机。

大家好，也许这段代码可以帮助人们使用谷歌驱动器作为一项服务，可以与 cronjob/cli 一起使用来上传、删除和下载无限文件大小的文件。

它还没有完成，但它是 google apiclient 的包装器。 并可用于上传、下载和删除文件。

<?php

namespace App\Model\Google;

class Drive
{
public $pixie;

protected $_config;
protected $_client;
protected $_service;

public function __construct(\App\Pixie $pixie)
{
    $this->pixie = $pixie;
    $this->_config = $this->pixie->config->get('googledrive');

    $this->_client = new \Google_Client();
    $this->_client->setClientId($this->_config['clientId']);
    $this->_client->setClientSecret($this->_config['clientSecret']);
    $this->_client->setRedirectUri($this->_config['redirectUri']); //
    $this->_client->addScope($this->_config['scope']); // scope: https://www.googleapis.com/auth/drive
    $this->_client->setAccessType($this->_config['accessType']); // offline
    $token = $this->_client->refreshToken($this->_config['refreshToken']);

    $this->_service = new \Google_Service_Drive($this->_client);
}

/**
 * UPLOAD FILE
 */
public function uploadFile($filename, $file)
{
    $gdriveFile = new \Google_Service_Drive_DriveFile();
    $gdriveFile->title = $filename;

    $chunkSizeBytes = 1 * 1024 * 1024;

    // Call the API with the media upload, defer so it doesn't immediately return.
    $this->_client->setDefer(true);
    $request = $this->_service->files->insert($gdriveFile);
    $mimeType = 'text/plain';
    // Create a media file upload to represent our upload process.
    $media = new \Google_Http_MediaFileUpload(
      $this->_client,
      $request,
      $mimeType,
      null,
      true,
      $chunkSizeBytes
    );

    $media->setFileSize(filesize($file));

    // Upload the various chunks. $status will be false until the process is
    // complete.
    $status = false;
    $handle = fopen($file, "rb");
    while (!$status && !feof($handle)) {
        $chunk = fread($handle, $chunkSizeBytes);
        $status = $media->nextChunk($chunk);
    }

    // The final value of $status will be the data from the API for the object
    // that has been uploaded.
    $result = false;
    if ($status !== false) {
        $result = $status;
    }

    return $result;
}
