【问题描述】：

我最近下载了用于 PHP 的 Google API 客户端库，将其上传到我的网站，并使用 Google 提供的代码连接我的日历。第一部分效果很好。我被发送到：https://accounts.google.com/o/oauth2/auth?response_type=code&redirect_uri=http 我按下接受按钮。我使用 authcode 被重定向回这个文件。但是这条线失败了：
$accessToken = $client->authenticate($authCode);

require_once ('google-api-php-client/autoload.php'); // path to autoload.php
if ($_GET[code] == FALSE) {
$client = new Google_Client();
$client->setClientId('My client ID');
$client->setClientSecret('My secret');
$client->setRedirectUri('http://'); // path to this file.
$client->addScope('https://www.googleapis.com/auth/calendar');
$client->setAccessType('offline');
$client->setApprovalPrompt('force');
$service = new Google_Service_Calendar($client);
$authUrl = $client->createAuthUrl();
header("location: $authUrl"); // sends me to account.google.com  I accept and get send back to    this file :-)
}
Else {
//$authCode = trim(fgets(STDIN));
$authCode = $_GET[code]; // get authcode from google
//Exchange authorization code for access token
$accessToken = $client->authenticate($authCode); //Fatal error: Call to a member function on a              strong text**non-object in authenticate() on line 23
$client->setAccessToken($accessToken);

【问题讨论】：

它是如何失败的？它会给出错误消息吗？我们需要更多信息来帮助您。
应该是$_GET['code']

【解决方案1】：

$client 变量需要在if 分支之外的范围内，如：

require_once ('google-api-php-client/autoload.php'); // path to autoload.php

$client = new Google_Client();
$client->setClientId('My client ID');
$client->setClientSecret('My secret');
$client->setRedirectUri('http://'); // path to this file.
$client->addScope('https://www.googleapis.com/auth/calendar');
$client->setAccessType('offline');
$client->setApprovalPrompt('force');
$service = new Google_Service_Calendar($client);

if ($_GET['code'] == FALSE) {
  $authUrl = $client->createAuthUrl();
  header("location: $authUrl"); // sends me to account.google.com  I accept and get send back to    this file :-)
} else {
  //$authCode = trim(fgets(STDIN));
  $authCode = $_GET['code']; // get authcode from google
  //Exchange authorization code for access token
  $accessToken = $client->authenticate($authCode); //Fatal error: Call to a member function on a              strong text**non-object in authenticate() on line 23
  $client->setAccessToken($accessToken);
}
