Laravel Redirect::to() not working
提问by Carwyn Stephen
I am creating a twitter log in feature for my project, the oauth step where the user has granted permission for my app to use their data returns the user to the /twitter-auth route, this route in turn initiates this method:
我正在为我的项目创建一个 twitter 登录功能，用户已授予我的应用程序使用其数据的权限的 oauth 步骤将用户返回到 /twitter-auth 路由，该路由依次启动此方法：
public function auth() {
/* Oauth token */
$token = Input::get('oauth_token');
/* Verifier token */
$verifier = Input::get('oauth_verifier');
/* Request access token */
$accessToken = Twitter::oAuthAccessToken($token, $verifier);
/* Set the session variables from the acccess token above */
Session::set('user_id', $accessToken['user_id']);
Session::set('username', $accessToken['screen_name']);
Session::set('oauth_token', $accessToken['oauth_token']);
Session::set('oauth_token_secret', $accessToken['oauth_token_secret']);
/* Determine if the user already exists in the database, if he/she does, then
only update the user, otherwise, store a new user. Also pass an instance of the
accessToken as flash data in both instances. */
if( User::where('twitter_id', $accessToken['user_id'])->first() == null )
{
$newUser = array(
'username' => $accessToken['screen_name'],
'oauth_token' => $accessToken['oauth_token'],
'oauth_token_secret' => $accessToken['oauth_token_secret'],
'twitter_id' => $accessToken['user_id']
);
User::create( $newUser );
return Redirect::to('/');
}
else
{
$userToUpdate = User::where('twitter_id', Session::get('user_id'))->first();
$userToUpdate->username = $accessToken['screen_name'];
$userToUpdate->oauth_token = $accessToken['oauth_token'];
$userToUpdate->oauth_token_secret = $accessToken['oauth_token_secret'];
$userToUpdate->twitter_id = $accessToken['user_id'];
$userToUpdate->save();
return Redirect::to('/');
}
}
The user is saved/updated as necessary, but the user is not redirected to the home page. This happens with the redirect code both inside and outside of the IF statement. I was wondering if anyone could give me any clues as to why the redirect isn't working?
根据需要保存/更新用户，但不会将用户重定向到主页。这发生在 IF 语句内部和外部的重定向代码中。我想知道是否有人能给我任何关于为什么重定向不起作用的线索？

You are missing a return
你缺少一个 return
your function in this case auth()is returning the Redirectobject but is the function calling your auth()function is returning the result back to the controller?
在这种情况下，您的函数auth()正在返回Redirect对象，但是调用您的auth()函数的函数是否将结果返回给控制器？
回答by Haisum Usman
Returning a Redirect to execute it is only possible from routes, controller actions and filters. Otherwise you have to call send()
返回重定向以执行它只能从路由、控制器操作和过滤器中返回。否则你必须调用 send()
Redirect::to('login')->send();
重定向::到('登录')->发送();

Please make sure that in your controller, you return the Redirect class that is from auth() function. Just tested your code and works :
请确保在您的控制器中，您返回来自 auth() 函数的 Redirect 类。刚刚测试了您的代码并工作：
let's say you have a UserController :
假设您有一个 UserController ：
routes.php
路由文件
Route::get('twitter-auth',array('as'=>'twitter-auth', 'uses'=>'UserController@twitterAuth'));
UserController the user model class is just passed by dependency injection, to test this part also.
UserController 用户模型类只是通过依赖注入传递的，也测试这部分。
<?php
class UserController extends BaseController {
public function __construct(User $u){
$this->user = $u;
}
public function twitterAuth(){
return $this->user->auth();
}
}
User model : I had to modify the code a little to fit my setup also
用户模型：我不得不稍微修改代码以适应我的设置
public function auth(){
/* Oauth token */
$token = Input::get('oauth_token');
/* Verifier token */
$verifier = Input::get('oauth_verifier');
/* Request access token */
//$accessToken = Twitter::oAuthAccessToken($token, $verifier);
//emulate the request of access Token
$accessToken = [
'user_id'=>'11',
'screen_name'=>'fewfewfew',
'oauth_token'=>'12312321',
'oauth_token_secret'=>'12312232323'
];
/* Set the session variables from the acccess token above */
Session::set('user_id', $accessToken['user_id']);
Session::set('username', $accessToken['screen_name']);
Session::set('oauth_token', $accessToken['oauth_token']);
Session::set('oauth_token_secret', $accessToken['oauth_token_secret']);
/* Determine if the user already exists in the database, if he/she does, then
only update the user, otherwise, store a new user. Also pass an instance of the
accessToken as flash data in both instances. */
if( User::where('twitter_id', $accessToken['user_id'])->first() == null )
{
$newUser = array(
'username' => $accessToken['screen_name'],
'oauth_token' => $accessToken['oauth_token'],
'oauth_token_secret' => $accessToken['oauth_token_secret'],
'twitter_id' => $accessToken['user_id']
);
User::create( $newUser );
return Redirect::to('/');
}
else
{
$userToUpdate = User::where('twitter_id', Session::get('user_id'))->first();
$userToUpdate->username = $accessToken['screen_name'];
$userToUpdate->oauth_token = $accessToken['oauth_token'];
$userToUpdate->oauth_token_secret = $accessToken['oauth_token_secret'];
$userToUpdate->twitter_id = $accessToken['user_id'];
$userToUpdate->save();
return Redirect::to('/');
}
}
Let me know if this is what you wanted
