PHP:Google plus Oauth 2.0 – 获取OAuth2访问令牌时出错,消息:’invalid_client’

使用PHP Lib v2,Oauth 2.0,使用Google登录.

经过很长一段时间花在它上面我最终配置,它工作一次很好,但之后它没有工作.点击登录链接后,用户需要对Google进行身份验证.工作正常,直到认证完成.

在使用GET变量回调时:

?code=something&authuser=0&prompt=consent&session_state=something

它产生以下错误:

Fatal error: Uncaught exception ‘Google_AuthException’ with message
‘Error fetching OAuth2 access token, message: ‘invalid_client” in
C:\xampp\htdocs\test\google-api-php-client\src\auth\Google_OAuth2.php:115
Stack trace: #0
C:\xampp\htdocs\test\google-api-php-client\src\Google_Client.php(127):
Google_OAuth2->authenticate(Array, 4/xUGSPbXR0LNzW…’) #1

Google_Client->authenticate(‘4/xUGSPbXR0LNzW…’) #2 {main} thrown in
C:\xampp\htdocs\test\google-api-php-client\src\auth\Google_OAuth2.php
on line 115

使用以下代码(它将帮助您理解):

<?php
ini_set('display_errors',1);
error_reporting(E_ALL);

require_once 'src/Google_Client.php';
require_once 'src/contrib/Google_PlusService.php';

session_start();

$client = new Google_Client();
$client->setApplicationName("Google+ PHP Starter Application");
$plus = new Google_PlusService($client);

if (isset($_REQUEST['logout'])) {
  unset($_SESSION['access_token']);
}

if (isset($_GET['code'])) {
  $client->authenticate($_GET['code']);
  $_SESSION['access_token'] = $client->getAccessToken();
  header('Location: http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']);
}

if (isset($_SESSION['access_token'])) {
  $client->setAccessToken($_SESSION['access_token']);
}

if ($client->getAccessToken()) {
  $me = $plus->people->get('me');
  $url = filter_var($me['url'], FILTER_VALIDATE_URL);
  $img = filter_var($me['image']['url'], FILTER_VALIDATE_URL);
  $name = filter_var($me['displayName'], FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH);
  $personMarkup = "<a rel='me' href='$url'>$name</a><div><img src='$img'></div>";

  $optParams = array('maxResults' => 100);
  $activities = $plus->activities->listActivities('me', 'public', $optParams);
  $activityMarkup = '';
  foreach($activities['items'] as $activity) {
    $url = filter_var($activity['url'], FILTER_VALIDATE_URL);
    $title = filter_var($activity['title'], FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH);
    $content = filter_var($activity['object']['content'], FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH);
    $activityMarkup .= "<div class='activity'><a href='$url'>$title</a><div>$content</div></div>";
  }

  $_SESSION['access_token'] = $client->getAccessToken();
} else {
  $authUrl = $client->createAuthUrl();
}
?>

从这里获取源文件:Google APIs Client Library for PHP

已经完成了:

>客户ID:好的
>客户秘密:好的
>重定向URI:好的
> Google API:ON

注意:

在localhost上工作.

最佳答案
有同样的问题.通过删除客户端密钥中的额外空间来修复它.当您从谷歌api控制台复制它时,您将获得额外的空间.
