Laravel Vuejs 实战:开发知乎 (42-44)用户头像

1.组件式上传头像vue组件:

安装扩展包:vue-image-crop-upload 或者 Vue Avatar Cropper我用的这个,暂时弃坑,需要加一个csrftoken

执行:

  1 npm i vue-avatar-cropper
  1 npm install & npm run watch-poll

使用vue-image-crop-upload

执行:

  1 npm install vue-image-crop-upload
  1 npm run watch-poll

2.路由:

添加:

  1 #region
  2 //访问用户详细页面
  3 
  4 Route::get('/avatar', 'UserController@avatar')->name('users.avatar');
  5 
  6 #endregion
  7 

3.执行:

  1 php artisan make:controller UserController

增加UserContoller.php,代码如下:

  1 <?php
  2 
  3 namespace AppHttpControllers;
  4 
  5 use IlluminateHttpRequest;
  6 
  7 class UserController extends Controller
  8 {
  9     //
 10 
 11     /** 返回用户avatar页面视图
 12      * @return IlluminateContractsViewFactory|IlluminateViewView
 13      */
 14     public function avatar()
 15     {
 16         return view('users._avatar');
 17     }
 18 
 19 
 20 }
 21 
 22 
UserController.php

4.增加视图文件:viewsusers\_avatar.blade.php:

  1 @extends('layouts.app')
  2 
  3 @section('content')
  4 
  5     <div class="container">
  6         <div class="row">
  7             <div class="col-md-8 col-md-offset-2">
  8                 <div class="card">
  9                     <div class="card-header">
 10                         更换头像
 11                     </div>
 12                     <div class="card-body">
 13                         <avatar avatar="{{ auth()->user()->avatar }}"></avatar>
 14                     </div>
 15                 </div>
 16             </div>
 17         </div>
 18     </div>
 19 
 20 @endsection
 21 
 22 
_avatar.blade.php

5.vue组件:

执行:

  1 npm install babel-polyfill
安装babel-polyfill

代码:

  1 <template>
  2     <div>
  3         <a class="btn btn-success" @click="toggleShow">设置头像</a>
  4         <my-upload field="img"
  5                    @crop-success="cropSuccess"
  6                    @crop-upload-success="cropUploadSuccess"
  7                    @crop-upload-fail="cropUploadFail"
  8                    v-model="show"
  9                    :width="300"
 10                    :height="300"
 11                    url="/upload"

UserContoller.php增加代码如下:

  1 <?php

  5 use IlluminateHttpRequest;
  6 
  7 class UserController extends Controller
  8 {
  9     //
