Question

尝试使用Vuejs从数据库中获取一些数据。我的users表中有一些虚拟数据。我想在我看来展示它们。问题是页面加载，它无法从users表中获取数据。它不会给出任何控制台错误。我检查了数据库连接，重新启动了服务器，还检查了邮递员的api数据。它工作正常。

观点：

fetchUser.blade.php

@extends('layout')
@section('content')

<div id="UserController">

  <table class="table table-hover table-striped">
    <thead>
      <th>Id</th>
      <th>Name</th>
      <th>Email</th>
      <th>Address</th>
    </thead>
    <tbody>
      <tr v-for="user in users">
          <td>@{{ user.id }}</td>
          <td>@{{ user.name }}</td>
          <td>@{{ user.email }}</td>
          <td>@{{ user.address }}</td>
          <td>@{{ user.created_at }}</td>
          <td>@{{ user.updated_at }}</td>
      </tr>
    </tbody>
  </table>

</div>

@endsection
@section('scripts')

@endsection

的script.js

var vm = new Vue({
    el: '#UserController',

    methods: {
      fetchUser: function(){
          this.$http.get('api/users', function(data) {
              this.$set('users', data )
          })
      }
    },

      ready: function(){

    }
});

web.php

Route::get('/', function () {
    return view('fetchUser');
});

api.php

<?php

use Illuminate\Http\Request;
use App\User;
Route::get('/users', function(){
    return User::all();
});

你应该使用then，并在ready函数中调用fetchUser

 data:{
   users: []
 },

 methods:{
     fetchUser: function(){
          this.$http.get('api/users').then(function(response){
                this.$set('users', response.data);
          }, function(response){
              // error callback
          });
 },

 ready: function(){
        this.fetchUser();
        }
