我试图为 wordpress 网站添加 Google+ 身份验证。我想要什么:如果用户未在网站上注册,则在 Google+ 中进行身份验证后 - 我将他重定向到他输入用户名的页面;如果用户已经注册 - 它将登录。这里是我的 js 代码:
function doGooglePlusLogin(authResult) {
    if (authResult['code']) {
        jQuery('#signinButton').attr('style', 'display: none');
        jQuery.ajax({
            url: '<?php echo site_url(); ?>/wp-admin/admin-ajax.php',
            type: 'get',
            dataType: 'json',
            data: {
                action: 'login_gplus',
                code: authResult['code']
            },
            success: function(result) {
            },
        });
    } else if (authResult['error']) {
    }
}
这是我的php代码:
function login_gplus() {
$response = array();
if (isset($_GET['code']) && !empty($_GET['code'])) {
    @session_start();
    $client = new Google_Client();
    $client->setApplicationName('Test');
    $client->setAccessType('offline');
    $client->setClientId(get_option(SOCIAL_GPLUS_CLIENT_ID));
    $client->setClientSecret(get_option(SOCIAL_GPLUS_CLIENT_SECRET));
    $client->setDeveloperKey(get_option(SOCIAL_GPLUS_API_KEY));
    $client->setRedirectUri(get_option(SOCIAL_GPLUS_REDIRECT_URIS));
    $client->setApprovalPrompt('auto');
    $code = $_GET['code'];
    $client->authenticate($code);
    $token = json_decode($client->getAccessToken());
    $reqUrl = 'https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=' . $token->access_token;
    $req = new Google_HttpRequest($reqUrl);
    $tokenInfo = json_decode(
            $client->getIo()
                    ->authenticatedRequest($req)
                    ->getResponseBody());
    if ($tokenInfo->error) {
        $response['test'] = $tokenInfo->error;
        send_json_response($response);
        die();
    }
    if ($tokenInfo->audience != get_option(SOCIAL_GPLUS_CLIENT_ID)) {
        $response['test'] = "Token's client ID does not match app's.";
        send_json_response($response);
        die();
    }
    $response['test'] = 'Succesfully connected with token: ' . print_r($token, true);
}
send_json_response($response);
die();
}
用户在 Google+ 中成功授权,但在 php 中我得到了这个:
致命错误:在 /var/www/html/v4/wp-content/plugins/social/google-plus/google-api/auth 中带有消息“获取 OAuth2 访问令牌时出错,消息:'redirect_uri_mismatch'”的未捕获异常“Google_AuthException” /Google_OAuth2.php:113堆栈跟踪:#0 /var/www/html/v4/wp-content/plugins/social/google-plus/google-api/Google_Client.php(131): Google_OAuth2->authenticate(Array, ' 4/ScmpTqEIWt0SJ...')#1 /var/www/html/v4/wp-content/plugins/social/google-plus/functions.php(35): Google_Client->authenticate('4/ScmpTqEIWt0SJ...

在应用程序设置重定向 URI 中指定为http://example.com/wp-admin/admin-ajax.php。我做错了什么?
编辑:
Google+ 登录按钮定义:
<span id="signinButton">
  <span class="g-signin"
   data-callback="doGooglePlusLogin"
   data-clientid="<?php echo $this->gplus_client_id; ?>"
   data-cookiepolicy="single_host_origin" data-accesstype="offline"
   data-requestvisibleactions="http://schemas.google.com/AddActivity"
   data-scope="https://www.googleapis.com/auth/plus.login">
  </span>
</span>
SOCIAL_GPLUS_REDIRECT_URIS 是example.com/wp-admin/admin-ajax.php?action=login_gplus
