Vue.js configuration Axios used for AJAX request data

* Install Axios with NPM

Switch to the project's root directory

NPM Install--save Axios Vue-axios

　　

* Introduce Axios in the Vue portal file./src/main.js, add 2 lines of code

Axiosimport Axios from ' Axios ' vue.prototype. $http = Axios

　　

* the./src/main.js entry file is as follows:

The Vue build version to load with the ' import ' command//(runtime-only or standalone) have been set in Webpack.base.con F with a alias.import vue from ' Vue ' import app./app ' import router from './router '//Axiosimport Axios from ' Axios ' Vue.prototype. $http = Axios Vue.config.productionTip = False/* eslint-disable no-new */new Vue ({  el: ' #app ',  rou ter, components  : {App},  Template: ' <App/> '})

* Generate data files./assets/data/people.json

{"People": [{"id": 1, "name": "Jack", "age": +, "gender": "Male"},{"id": 2, "name": "Bill", "Age": "Gender": "Male"},{" ID ": 3," "Name": "Tracy", "Age": $, "gender": "Female"},{"id": 4, "name": "Chris", "Age": $, "gender": "Male"}]}

Why can't I access it directly in the component: /assets/data/people.json?

* PHP generated data (requires cross-domain cors)

<?php/** * Test axios=> people.json */header (' Content-type:text/json; Charset=utf-8 '); Header (' access-control-allow-origin:* '); header (' Access-control-allow-methods:get '); Header (' Access-control-allow-headers:x-requested-with,content-type '); $data = new \stdclass (); $data->people = [    [        "id] + 1,        " name "=" Jack ",        " age "and" age ","        ge NDEr "+" Male "    ],    [        " id "= 2,        " name "=" Bill ",        " age "="        gender "and" Male "    ],    [        " id "= 3,        " name "=" Tracy ",        " age "="        gender "and" Female "    ],    [        "id" = 4,        "name" = "Chris",        "age" = +,        "gender" = "Male"    ],    [        "id" = 5,        "name" = "guanmengying",        "age" and "        gender" = "Female"    ]];echo Json_encode ($data, true);

* Start PHP interface

Php-s 0.0.0.0:8081

　　

* Test this interface can be accessed by the browser http://localhost:8081/person.php

or command-line Curl http://localhost:8081/people.php

Output:

{"People": [{"id": 1, "name": "Jack", "age": +, "gender": "Male"},{"id": 2, "name": "Bill", "Age": "Gender": "Male"},{" ID ": 3," "Name": "Tracy", "Age": $, "gender": "Female"},{"id": 4, "name": "Chris", "Age": $, "gender": "Male"},{"id": 5, " Name ":" Guanmengying "," Age ":" Gender ":" Female "}]}

* Routing files./src/router/index.js

According to the default HelloWorld divert, you can

Import vue from ' Vue ' import Router from ' vue-router ' import HelloWorld from ' @/components/helloworld ' import person from ' @/ Components/person ' Vue.use (Router) export default new Router ({  routes: [    {      path: '/',      name: ' HelloWorld ',      component:helloworld    },    {      path: '/person ',      name: ' Person ',      Component:person    }  ]})

* Template file./src/components/person.vue

<template><div class= "wrapper" > <fieldset> <legend> Create New Person </legend> <div class= "Form-group" > <label>name:                </label> <input type= "text" v-model= "Newperson.name"/> </div> <div class= "Form-group" > <label>Age:</label> <input Type                    = "text" v-model= "Newperson.age"/> </div> <div class= "Form-group" >                    <label>gender:</label> <select v-model= "Newperson.gender" >                <option value= "Male" >Male</option> <option value= "Female" >Female</option> </select> </div> <div class= "Form-group" > &L T;label></label> <button @click = "Createperson" >Create</button> </div> </fieldset> <                    table> <thead> <tr> <th>Name</th>                <th>Age</th> <th>gender</th> <th>Delete</th>                </tr> </thead> <!--cycle must specify key---<tbody>                    <tr v-for= "(person) in people": key= "Person.id" > <td>{{person.name}}</td>                    <td>{{person.age}}</td> <td>{{person.gender}}</td> <td:class= "' Text-center '" > <!--<button @click = "Deleteperson ($index)" >de        Lete</button>--<button @click = "Deleteperson (person.id)" >Delete</button>            </td> </tr> </tbody> </table></div> </templa te><style> #app {margin-top:10px;} Table {margin:20px Auto;}    </style><script>export Default {name: ' Person ', created:function () {var v = this;      V. $http. Get ("http://localhost:8081/people.php"). Then (function (resp) {v.people = Resp.data.people;      }). catch (function (error) {document.write (error.tostring ());  });    }, data () {return {newperson: {name: "", age:0, Gender: "Male"}, People: []  };      }, Methods: {createperson:function () {This.people.push (This.newperson);    After adding the Newperson object, reset the Newperson object This.newperson = {name: "", age:0, Gender: "Male"};      }, Deleteperson:function (ID) {//Find index var index, person;        person = This.people.find (the function (person, idx) {var Matchid = Person.id = = = ID; IF (matchid) {index = IDX;      } return Matchid;      });    Delete an array element This.people.splice (index, 1); }}};</script>

Major changes:

Created:function () {    var v = this;    Vue instance    v. $http      . Get ("http://localhost:8081/people.php")  //XHR      . Then (function (RESP) {        v.people = resp.data.people;  Bind data      })      . catch (function (error) {        document.write (error.tostring ());      });  },  Data () {    return {      //...      People: []  //empty array. Null can cause template compiling error    };  },

* Browser Access Http://localhost:8080/#/person
