Detailed explanation of the use of api interface in vue project

This time I will bring you a detailed explanation of the use of the api interface in the vue project. What are the precautions for the use of the api interface in the vue project. The following is a practical case, let's take a look.

The default vue project has been generated using vue-cli, installed axios, and developed based on element-ui. The axiosconfig directory and the api directory are at the same level, and they mainly record the configuration.

1. axiosConfig.js in the axiosconfig directory

import Vue from 'vue'
import axios from 'axios'
import qs from 'qs'
import { Message, Loading } from 'element-ui'
// 响应时间
axios.defaults.timeout = 5 * 1000
// 配置cookie
// axios.defaults.withCredentials = true
// 配置请求头
axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=UTF-8'
// 静态资源
Vue.prototype.$static = ''
// 配置接口地址
axios.defaults.baseURL = ''
var loadingInstance
// POST传参序列化(添加请求拦截器)
axios.interceptors.request.use(
 config => {
  loadingInstance = Loading.service({
   lock: true,
   text: '数据加载中，请稍后...',
   spinner: 'el-icon-loading',
   background: 'rgba(0, 0, 0, 0.7)'
  })
  if (config.method === 'post') {
   config.data = qs.stringify(config.data)
  }
  return config
 },
 err => {
  loadingInstance.close()
  Message.error('请求错误')
  return Promise.reject(err)
 }
)
// 返回状态判断(添加响应拦截器)
axios.interceptors.response.use(
 res => {
  if (res.data.code === 200) {
   loadingInstance.close()
   return res
  } else {
   loadingInstance.close()
   Message.error(res.data.msg)
  }
 },
 err => {
  loadingInstance.close()
  Message.error('请求失败，请稍后再试')
  return Promise.reject(err)
 }
)
// 发送请求
export function post (url, params) {
 return new Promise((resolve, reject) => {
  axios
   .post(url, params)
   .then(
    res => {
     resolve(res.data)
    },
    err => {
     reject(err.data)
    }
   )
   .catch(err => {
    reject(err.data)
   })
 })
}
export function get (url, params) {
 return new Promise((resolve, reject) => {
  axios
   .get(url, {
    params: params
   })
   .then(res => {
    resolve(res.data)
   })
   .catch(err => {
    reject(err.data)
   })
 })
}

2. index.js, api1.js, api2.js in the api directory

api1.js
import { post } from '../axiosconfig/'
export default {
  login(params) {
    return post('/users/api/login', params)
  }
}
api2.js
import { post } from '../axiosconfig/'
export default {
  regist(params) {
    return post('/users/api/regist', params)
  }
}
index.js
import user from './api1.js'
import active from './api2.js'
export default {
 api1,
 api2
}

3. main.js configuration

import api from './api/'
Vue.prototype.$api = api

4. Use

登录组件中
doLongin() {
 let params={}
 this.$api.api1.login(params).then(res => {
  console.log(res)
 })
}
注册组件中
doRegist() {
 let params={}
 this.$api.api2.regist(params).then(res => {
  console.log(res)
 })
}
