使用Google云端硬盘V3（V2工作正常）下载CSV文件会抛出错误403 [英] Download CSV file using Google Drive V3(V2 works perfect) throws error 403

问题描述

我使用 DRIVE V2 与服务帐户下载CSV文件，这一个工作正常。我要将DRIVE V2迁移到DRIVE V3。我已根据以下Google文档更改了我的脚本

Plz帮我解析使用G DRIVE V3下载CSV文件。有没有任何回归或函数滞后b / w V2，V3？

解决方案

由于Google Drive API for PHP是测试版，

错误调用GET
https://www.googleapis.com/drive/v3/files/0B5pkfK_IBDxjeHlTTDFFY01CXzQ?alt=media ：
（302）暂时移动该文档已移动此处。

此处的链接为：
https://www.googleapis.com/ 下载 / drive / v3 / files / 0B5pkfK_IBDxjeHlTTDFFY01CXzQ？alt = media

您可以看到API服务器建议新的链接 / drive ...。

在Google云端硬盘客户端库V3中，您可以通过将以下代码添加到src / Google / Http / REST .php第147行后：

  if（$ requestUrl =='drive / v3 / files / {fileId}'&& ; $ params ['alt'] ['value'] =='media'）
 $ requestUrl =download /\".$ requestUrl; 
  

希望有帮助...：）

I m using DRIVE V2 WITH Service Account to download CSV file,This one is working fine. I want to migrate DRIVE V2 to DRIVE V3 .So i changed my script as per below google documents

I. Download a file in drive V3

PHP Library & Drive API V3 used in this sample:

1.Sample script download CSV file using Drive V3

Method used: Using alt=media

Reason: this method only available in DRIVE V3

<?php
set_include_path( get_include_path() . PATH_SEPARATOR . 'Google' );
require_once 'Google/autoload.php';
require_once 'Google/Client.php';
require_once 'Google/Service/Drive.php';
try{
    //Get service document
    $service = get_service_document();
    //Download a csv file
    $data = $service->files->get("FILE ID", array( 'alt' => 'media'));
   print_r($data);
}
catch(Exception $e){
    print_r($e->getMessage());
}
//function to get service
function get_service_document(){
    $userstamp='[e-mail]';

//Enable below two lines if let know the clientid,tokens,etc.,
    $driveService=buildServiceDrive($userstamp,"SERVICE_ACCOUNT","https://www.googleapis.com/auth/drive","KEY.p12");
    return $driveService;
}
//building service
function buildServiceDrive($userEmail,$service_id,$scope,$service_filename) {
    $key = file_get_contents($service_filename);
    $auth = new Google_Auth_AssertionCredentials(
        $service_id,
        array($scope),
        $key);
    $auth->sub = $userEmail;
    $client = new Google_Client();
    $client->setAssertionCredentials($auth);
    return new Google_Service_Drive($client);
}

RESULT: I got the below issue

Error calling GET https://www.googleapis.com/drive/v3/files/0B5pkfK_IBDxjeHlTTDFFY01CXzQ?alt=media: (302)
Moved Temporarily
The document has moved here.

After clicked here. I saw below error.

{
 "error": {
  "errors": [
   {
    "domain": "usageLimits",
    "reason": "dailyLimitExceededUnreg",
    "message": "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup.",
    "extendedHelp": "https://code.google.com/apis/console"
   }
  ],
  "code": 403,
  "message": "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup."
 }
}

II. Download a file in Drive V2

I used alternate method to download CSV file from drive.

PHP Library & Drive API V2 used in this sample:

2.Sample Script download CSV file using Drive V2

Method used : Alternate method: using downloadUrl

<?php
set_include_path( get_include_path() . PATH_SEPARATOR . 'Google' );
require_once 'Google/autoload.php';
require_once 'Google/Client.php';
require_once 'Google/Service/Drive.php';
try{

    //Get service document
    $service = get_service_document();
    $data = $service->files->get("FILE ID");
    $url=$data->downloadUrl;
    $data=downloadFile($service,$url);
    print_r($data);
}
catch(Exception $e){
    print_r($e->getMessage());
}

//Alternate method using download URL
function downloadFile($service, $downloadUrl)
{
    if ($downloadUrl) {
        $request = new Google_Http_Request($downloadUrl, 'GET', null, null);
        $httpRequest = $service->getClient()->getAuth()->authenticatedRequest($request);
        if ($httpRequest->getResponseHttpCode() == 200) {
            return $httpRequest->getResponseBody();
        } else {
            echo "errr";
            return null;
        }
    } else {
        echo "empty";
        return null;
    }
}
//function to get service
function get_service_document(){
$driveService =buildServiceDrive([e-mail]',"SERVICE-ACCOUNT","https://www.googleapis.com/auth/drive","KEY.p12");
    return $driveService;
}
//building service
function buildServiceDrive($userEmail,$service_id,$scope,$service_filename) {
    $key = file_get_contents($service_filename);
    $auth = new Google_Auth_AssertionCredentials(
        $service_id,
        array($scope),
        $key);
    $auth->sub = $userEmail;
    $client = new Google_Client();
    $client->setAssertionCredentials($auth);
    return new Google_Service_Drive($client);
}

Result:

i got CSV file records, working fine

Plz help me resolve to download a CSV file using G DRIVE V3. Is there any regression or functions lagging b/w V2, V3?

解决方案

Since the Google Drive API for PHP is beta version, realize that some errors can be experienced by developers.

Error calling GET https://www.googleapis.com/drive/v3/files/0B5pkfK_IBDxjeHlTTDFFY01CXzQ?alt=media: (302) Moved Temporarily The document has moved here.

In this case, here's link is: https://www.googleapis.com/download/drive/v3/files/0B5pkfK_IBDxjeHlTTDFFY01CXzQ?alt=media

You can see the API Server suggest the new link "download" before "/drive...".

In Google Drive Client Library V3, here is the solution you can fix manually by adding the following code to src/Google/Http/REST.php after line 147:

if($requestUrl=='drive/v3/files/{fileId}' && $params['alt']['value']=='media')
  $requestUrl = "download/".$requestUrl;

Hope this help... :)
