如何使用 Google Drive API 和在 Web 服务器上运行的 PHP 代码在 Google Drive 中上传图像

问题描述

你好吗？希望你们一切都好。我将尝试使用谷歌驱动器 API 将图像上传到我的谷歌驱动器，一切都会好起来我通过 composer require google/apiclient:^2.0 成功安装了 composer.json 文件strong> 并且我成功下载了 credentials.json 但问题是当我要通过 PHP google-drive.PHP 生成访问令牌时，我得到了验证代码，但是当我将代码放入验证位置时，它给了我这样的错误

致命错误：未捕获的错误：未定义的常量“STDIN”在 C:\xampp\htdocs\imagebob\google-drive.PHP:41 堆栈跟踪：#0 C:\xampp\htdocs\imagebob\google-drive.PHP(62): getClient() shuja007/Shujaat#1 C:\xampp\htdocs\imagebob\form.PHP(1): include('C:\xampp\htdocs...') #2 {main} 被抛出 C:\xampp\htdocs\imagebob\google-drive.PHP 第 41 行

因此，当有人告诉我在 google-drive.PHP 类中的代码顶部定义 STDIN 时，我解决了上述错误，但是在我定义了 STDIN 之后在我的代码中，然后我面临新问题，我不知道这个错误意味着有人可以帮助我解决这个错误，错误是

未捕获的 invalidargumentexception：C:\xampp\htdocs\imagebob\vendor\google\apiclient\src\Google\Client.PHP:176 中的代码无效：#0 C:\xampp\htdocs\imagebob\google-drive .PHP(52): Google_Client->fetchAccesstokenWithAuthCode('') #1 C:\xampp\htdocs\imagebob\google-drive.PHP(70): getClient() #2 C:\xampp\htdocs\imagebob\submit。 PHP(3): require('C:\xampp\htdocs...') #3 {main} 扔在 C:\xampp\htdocs\imagebob\vendor\google\apiclient\src\Google\Client.PHP 上线176

在下面我将用单独的类解释我的所有代码请检查并给我正确的解决方案我是这个领域的新手所以请简要解释我我不知道我是否定义了“STDIN”正确的地方与否并告诉我我的错误发生在哪里。提前谢谢大家。

form.PHP“这是我的第一堂课”

<?PHP include 'google-drive.PHP';?>

google-drive.PHP“这是我的第二个类，其中包含 form.PHP 类”

<?PHP
