Google Drive API：为什么使用服务帐户在下载文件时会将我带到 Google Drive 登录窗口？

Question

我有一个用于使用 Google 服务帐户上传和下载文件的脚本。这看起来工作正常，但现在下载时却不行了。单击链接下载文件而不是开始下载时，会出现 Google Drive 登录页面。 老实说，我不知道对 Google Cloud 配置的 PHP 代码进行了任何更改。我检查了两者，没有发现任何变化或错误。我必须说我不是专家。

提前致谢。

我已经检查了代码和 Google 配置。我期望将文件从 php 代码上传和下载到 Google Drive。结果是上传文件很好，但是下载这些文件时会出现 Google Drive 登录窗口，而不是下载文件。

require_once 'google-api-php-client/vendor/autoload.php';
putenv('GOOGLE_APPLICATION_CREDENTIALS=googlecredentials-path-file.json');
$client = new Google_Client();
$client->useApplicationDefaultCredentials();
$client->setScopes(['https://www.googleapis.com/auth/drive.file']);
try {
   $service = new Google_Service_Drive($client);
  $google_file = new Google_Service_Drive_DriveFile();
  
  $file_path = 'buho.jpg';
    
  $google_file->setName($file_path);
  $google_file->setParents(['Google-Drive-folder-id']); 
  $google_file->setDescription('File uploaded from a PHP application');
  $google_file->setMimeType('image/jpeg');
  $result = $service->files->create(
    $google_file,
    array(
      'data' => file_get_contents($file_path),
      'mimeType' => 'image/jpeg',
      'uploadType' => 'media'
    )
  );
  echo '<a href="https://drive.google.com/open?id=' . $result->id . '" target="_blank">' . $result->name .'</a>';

您可以生成一个链接，使用该链接时，无需登录即可访问。 注意：任何知道链接的人都可以访问

<?php

require_once "google-api-php-client/vendor/autoload.php";
putenv("GOOGLE_APPLICATION_CREDENTIALS=googlecredentials-path-file.json");
$client = new Google_Client();
$client->useApplicationDefaultCredentials();
$client->setScopes(["https://www.googleapis.com/auth/drive.file"]);
try {
    $service = new Google_Service_Drive($client);
    $google_file = new Google_Service_Drive_DriveFile();

    $file_path = "buho.jpg";

    $google_file->setName($file_path);
    $google_file->setParents(["Google-Drive-folder-id"]);
    $google_file->setDescription("File uploaded from a PHP application");
    $google_file->setMimeType("image/jpeg");
    $result = $service->files->create($google_file, [
        "data" => file_get_contents($file_path),
        "mimeType" => "image/jpeg",
        "uploadType" => "media",
    ]);
    // Set permissions to create a shareable link
    $permission = new Google_Service_Drive_Permission([
        "type" => "anyone",
        "role" => "reader",
    ]);
    $service->permissions->create($result->id, $permission);

    // Get the shareable link
    $file = $service->files->get($result->id, ["fields" => "webViewLink"]);
    $shareableLink = $file->webViewLink;

    echo '<a href="' .
        $shareableLink .
        '" target="_blank">' .
        $result->name .
        "</a>";
} catch (Exception $e) {
    // handle exception
}
