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:

致命错误:在C:\ xampp \ htdocs \ test \ google-api-php-client \ src \ auth \ Google_OAuth2.php中显示错误消息“Google_AuthException”,并显示错误“获取OAuth2访问令牌,消息:'invalid_client'': 115堆栈跟踪:#0 C:\ xampp \ htdocs \ test \ google-api-php-client \ src \ Google_Client.php(127):Google_OAuth2-> authenticate(Array,4 / xUGSPbXR0LNzW ...')#1C :\ xampp \ htdocs \ test \ google-api-php-client \ index.php(40):在C:\ xampp \ htdocs中抛出Google_Client-> authenticate('4 / xUGSPbXR0LNzW ...')#2 第115行的\ test \ google-api-php-client \ src \ auth \ Google_OAuth2.php

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();
}
?>

从此处获取源文件:适用于PHP的Google API客户端库

已经完成了:

  • 客户ID:好的

  • 客户秘密:好的

  • 重定向URI:好的

  • Google API:开启

Note:

在localhost上工作 .

    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 .

    仔细检查您的Google应用凭据(客户端ID,客户端密钥,API密钥)是否有效并正确传递给客户端 .
