谷歌| OAuth 400 redirect_uri_mismatch

Question

我想创建Google身份验证但无法找到错误： 我的代码如下：

$client_id = 'xxxxxxx-4bsrudsadhna5817fddlhmf02ihgrcr0.apps.googleusercontent.com'; 
$client_secret = 'xxxxxxxxxxxxxxxxxx';
$redirect_uri = 'http://`localhost`/joomla/index.php?option=com_component&view=quest&task=signup'; 
$url = 'https://accounts.google.com/o/oauth2/auth';
$params = array(
'redirect_uri'      => $redirect_uri,
'response_type'     => 'code',
'client_id'         => $client_id,
'scope'             => 'https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile'
);  

$this->google_auth_link = $url . '?' . urldecode(http_build_query($params));

echo '<a href="'.$this->google_auth_link.'">Login using Google +</a>';

但这会让我回头：

400 - That’s an error.
Error: redirect_uri_mismatch

请求中的重定向URI：http：// localhost /joomla/index.php?option=com_component与注册的重定向URI不匹配

P.S似乎已经删除了URI的这一部分：＆amp; view = quest＆amp; task = signup

谢谢！

您无法在单引号内使用反引号运算符。第3行应该是

$redirect_uri = 'http://'.`localhost`.'/joomla/index.php?option=com_component&view=quest&task=signup';
