問題是憑證文件夾中的credential.json文件以前未生成。我在我的網絡瀏覽器中收到了一個字符串，如下所示 https://accounts.google.com/o/oauth2/auth?response_type=code&access_type=offline&client_id=XXXXXXX&redirect_uri=XXXXX&state&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcalendar.readonly&approval_prompt=auto 我在我的Web瀏覽器中打開此URL時收到了代碼。我抄的代碼和替換$ AUTHCODE =修剪（與fgets（STDIN））以$ AUTHCODE =修剪（CODE_I_GOT）。 此過程已生成credential.json文件，之後我能夠成功運行我的代碼

你可以參考這個related GitHub issue其中指出，可能的原因API拋出一個「無效代碼」異常的原因是，訪問令牌格式不匹配在新生成的格式API。

此代碼還可以幫助：

• while getting contents, I used serialize function

  • Example: $accessToken = serialize (file_get_contents($credentialsPath));

• while inserting contents, I used deserialize function

  • Example: $accessToken = derialize(file_put_contents($credentialsPath, $accessToken););

嘗試在在讀$accessToken能夠解決您的問題所有的地方寫$accessToken和unserialize()所有地方插入serialize()。
