14.Main.jsの構成

---

1. untilフォルダー内のrequest.js、axios応答インターセプト

// 封装axios
import axios from 'axios';

// 创建axios实例
let service = axios.create({
    baseURL: "http://localhost:8080",
    timeout: 5000   // 请求超时时长
})

// 请求拦截
service.interceptors.request.use( config => {
    // 查看是否有token
    // 从store中找  是否有token
    return config;
}, error => Promise.reject(error))

// 响应拦截
service.interceptors.response.use( response => {
    /* 
        根据不同响应 status code 进行 配置
        code
            200  // 接口正常
            5001  // 非法token
            5002  // 其他客户端登录
            5003  // token已过期
    */
    let res = response.data;
    if( res.code !== 200 ) {
        return Promise.reject('error');
    } else {
        return res;
    }
}, error => Promise.reject(error));

export default service;

2.apiフォルダーのexcel.js

import request from './../utils/request';

export function getDateList () {
  return request({
    url: '/excel/get', 
    method: 'get',
    params: {}
  })
} 

3.モックファイルのindex.jsインターフェース

//接口文件
import Mock from 'mockjs'
import excel from './excel'
// 设置全局延时 没有延时的话有时候会检测不到数据变化
Mock.setup({
    timeout: '300-600'
})


Mock.mock(/\/excel\/get/, 'get', excel.getMoneyList)

export default Mock

4.モックファイルのexcel.jsインターフェース

//模拟资金管理后台数据
import Mock from 'mockjs' // 导入mockjs 模块

let List = []// 定义我们需要的数据
const count = 10

for (let i = 0; i < count; i++) {
  List.push(Mock.mock({// 根据数据模板生成模拟数据
    id: Mock.Random.guid(),// 随机生成一个id
    username: Mock.Random.cname(),// 随机生成一个常见的中文姓名。
    address: Mock.mock('@county(true)'),// @county(true)为数据模板
    createTime: Mock.Random.datetime(),//生成时间
    income: Mock.Random.integer(0, 9999),//生成随机数
    pay: Mock.Random.integer(0, 9999), //生成随机数
    accoutCash: Mock.Random.integer(0, 9999),//生成随机数
	checked:false//标识当前数据状态
  }))

}
export default{
	getMoneyList:config =>{
		return{
			code:200,
			data:{
				list:List,
			}
		}
	}
}
