PHP 谷歌日历 API

Question

在项目中设置此功能的初始阶段。我已在 Google 开发者页面启用它并尝试遵循快速入门指南https://developers.google.com/calendar/quickstart/php然而，与大多数 Google API 教程一样，这个“快速入门”不起作用。我通过授权页面并获得了在终端中输入的代码，但很长一段时间后我才收到错误PHP Fatal error:  Uncaught RuntimeException: Unable to read from stream in [site root]/vendor/guzzlehttp/psr7/src/Stream.php    Stack trace:#0 [site root]/vendor/guzzlehttp/psr7/src/functions.php(382): GuzzleHttp\Psr7\Stream->read()    #1 [site root]/vendor/guzzlehttp/guzzle/src/Handler/StreamHandler.php(214): GuzzleHttp\Psr7\copy_to_stream()    #2 [site root]/vendor/guzzlehttp/guzzle/src/Handler/StreamHandler.php(133): GuzzleHttp\Handler\StreamHandler->drain()    #3 [site root]/vendor/guzzlehttp/guzzle/src/Handler/StreamHandler.php(50): GuzzleHttp\Handler\StreamHandler->createResponse()    #4 [site root]/vendor/guzzlehttp/guzzle/src/PrepareBodyMiddleware.php(66): GuzzleHttp\Handler\StreamHandler->__invoke()    #5 [site root]/vendor/guzzlehttp/guzzle/src/Middleware.php(29): GuzzleHttp\PrepareBodyMiddleware->__invoke()    #6 [site root]/vendor/guzzlehttp/guzzle/src/RedirectMiddleware.php(70): GuzzleHtt in [site root]/vendor/guzzlehttp/guzzle/src/Exception/RequestException.php on line 52不会创建 token.json 文件，但该目录是可写的。

怀疑谷歌代码是错误的。更改第 16 行的范围可以使其正确运行。

$client->setScopes("https://www.googleapis.com/auth/calendar.readonly");
