Question

我是CodeIgniter和PHP的新手。 Google API控制台中提供的重定向网址：

Redirect URIs:  http://localhost/testsaav/index.php/main/gmail_invite

以下代码显示了Request For Permission页面。当我点击Allow Access时，它会将我带到

http://localhost/testsaav/index.php/main/gmail_invite?code=4/CXD462cen-oEBe1GaHIH90hjqb2X.QpVsg7mG4AUXaDn_6y0ZQNgaCVLxeAI

我想将其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);

}

为什么你的视图中包含所有PHP代码？这不是MVC的工作方式。

逻辑代码应保存在Controller中，而不是View中。我建议你使用Codeiginter OAuth2库，因为来自Google的OAuth2 lib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，你可以使用这个：https://github.com/philsturgeon/codeigniter-oauth2

您被重定向到正确的控制器，因为此处设置了网址：

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

另请参阅Codeigniter的重定向方法： redirect('somecontroller/some_method')

向Controller发送Google API OAuth2响应
