Laravel Vuejs 实战:开发知乎 (2)用户登录

1.安装一个给用户提示的扩展包: 二选一: https://github.com/laracasts/flash 【我选的这个】https://github.com/oanhnn/laravel-flash-message

使用方法:在需要使用falsh消息的控制器中,调用flash方法即可:

如:

  1 public function store()
  2 {
  3     //flash('Welcome Aboard!');
  4     flash()->overlay('Welcome Aboard!', '登录提示');
  5     return home();
  6 }

同时可以如下方式调用:


  1 flash('Message')->success(): Set the flash theme to "success".
  2 flash('Message')->error(): Set the flash theme to "danger".
  3 flash('Message')->warning(): Set the flash theme to "warning".
  4 flash('Message')->overlay(): Render the message as an overlay.
  5 flash()->overlay('Modal Message', 'Modal Title'): Display a modal overlay with a title.
  6 flash('Message')->important(): Add a close button to the flash message.
  7 flash('Message')->error()->important(): Render a "danger" flash message that must be dismissed.

当上述设置的消息存储到了session中,就可以在view中显示出来了,通常情况下,提示的格式都大同小异,所以该扩展包提供了一个开箱即可使用的模板,可以自己修改也可以直接调用。

  1 @include('flash::message')

2.要显示提示:

可以参考:

  1 <!DOCTYPE html>
  2 <html lang="en">
  3 <head>
  4     <meta charset="UTF-8">
  5     <title>Document</title>
  6     <link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
  7 </head>
  8 <body>
  9 
 10 <div class="container">
 11     @include('flash::message')
 12 
 13     <p>Welcome to my website...</p>
 14 </div>
 15 
 16 <!-- If using flash()->important() or flash()->overlay(), you'll need to pull in the JS for Twitter Bootstrap. -->
 17 <script src="//code.jquery.com/jquery.js"></script>
 18 <script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
 19 
 20 <script>
 21     $('#flash-overlay-modal').modal();
 22 </script>
 23 
 24 </body>
 25 </html>

更多的使用方法可以参考GitHub的readme介绍。另外介绍一款扩展包可以自己学着尝试使用:http://tamtamchika.net/simple-flash/

如果script放在head部分 参考

  1 <!-- Scripts -->
  2 <script src="{{ mix('js/app.js') }}" defer></script> 

定义和用法 defer 属性规定当页面已完成加载后,才会执行脚本。 注释: defer 属性仅适用于外部脚本(只有在使用 src 属性时)。

最后修改的layouts/app.blade.php

  1 <!doctype html>
  2 <html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
  3 <head>
  4     <meta charset="utf-8">
  5     <meta name="viewport" content="width=device-width, initial-scale=1">
  6 
  7     <!-- CSRF Token -->
  8     <meta name="csrf-token" content="{{ csrf_token() }}">
  9 
 10     <title>{{ config('app.name', 'Laravel') }}</title>
 11 
 12 
 13     <!-- Fonts -->
 14     <link rel="dns-prefetch" href="//fonts.gstatic.com">
 15     <link href="https://fonts.googleapis.com/css?family=Nunito" rel="stylesheet">
 16 
 17     <!-- Styles -->
 18     <link href="{{ mix('css/app.css') }}" rel="stylesheet">
 19 </head>
 20 <body>
 21 <div id="app">
 22     <nav class="navbar navbar-expand-md navbar-light bg-white shadow-sm">
 23         <div class="container">
 24             <a class="navbar-brand" href="{{ url('/') }}">
 25                 {{ config('app.name', 'Laravel') }}

 27             <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent"
 28                     aria-controls="navbarSupportedContent" aria-expanded="false"
 29                     aria-label="{{ __('Toggle navigation') }}">
 30                 <span class="navbar-toggler-icon"></span>

 32 
 33             <div class="collapse navbar-collapse" id="navbarSupportedContent">
