我不熟悉CodeIgniter和PHP。 Google API控制台中给定的重定向URL:

Redirect URIs:  http://localhost/testsaav/index.php/main/gmail_invite
下面的代码显示了权限请求页面。当我单击
允许访问时
它会将我带到

http://localhost/testsaav/index.php/main/gmail_invite?code=4/CXD462cen-oEBe1GaHIH90hjqb2X.QpVsg7mG4AUXaDn_6y0ZQNgaCVLxeAI
我想将它重定向到另一个页面,并在那里显示响应。控制器方法

function gmail_invites($data)
{
   $this->load->view('socialInvites2',$data);

}
视图实现

            $client->setRedirectUri('http://localhost/testsaav/index.php/main/gmail_invite');

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

            if ($client->getAccessToken()) {
              $req = new Google_HttpRequest("https://www.google.com/m8/feeds/contacts/default/full");
              $val = $client->getIo()->authenticatedRequest($req);
              //$xml = simplexml_load_string($val->getResponseBody());

为什么视图中有那么多php代码?MVC不是这样工作的

逻辑代码应该保存在控制器中,而不是视图中。我建议您使用Codeiginter OAuth2库,因为来自Google的OAuth2库的原始代码并不意味着与Codeiginter或任何其他特定的MVC框架兼容。例如,您可以使用这个:

您被重定向到正确的控制器,因为url设置在此处:

还要看一下Codeigniter的重定向方法:
redirect('somecontroller/someu方法')
