Laravel 5.2 重定向成功消息

问题描述

我正在尝试将成功消息返回到我的 laravel 主页.

return redirect()->back()->withSuccess('IT WORKS!');

由于某种原因，运行此代码后变量 $success 没有得到任何值.

我用来显示成功消息的代码:

@if (!empty($success))<h1>{{$success}}</h1>@万一

我已将主页和时事通讯页面添加到 routes.php 中的 Web 中间件组，如下所示:

Route::group(['middleware' => 'web'], function () {路线::认证();路由::get('/', function () {返回视图('家');});Route::post('/newsletter/subscribe','NewsletterController@subscribe');});

有人知道为什么这似乎不起作用吗?

解决方案

您应该从 routes.php 中删除 web 中间件.手动添加 web 中间件会导致会话和在 Laravel 5.2.27 及更高版本中请求相关问题.

如果它没有帮助(仍然，保持 routes.php 没有网络中间件)，你可以尝试一些不同的方法:

return redirect()->back()->with('message', 'IT WORKS!');

如果存在则显示消息:

@if(session()->has('message'))<div class="alert alert-success">{{ session()->get('message') }}

For some reason the variable $success doesn't get any value after running this code.

I have added the home and newsletter page to the web middleware group in routes.php like this:

Route::group(['middleware' => 'web'], function () { Route::auth(); Route::get('/', function () { return view('home'); }); Route::post('/newsletter/subscribe','NewsletterController@subscribe'); });

You should remove web middleware from routes.php. Adding web middleware manually causes session and request related problems in Laravel 5.2.27 and higher.

If it didn't help (still, keep routes.php without web middleware), you can try little bit different approach:
