vue network setting method

Vue is a popular front-end development framework. Efficient, beautiful, and easy-to-maintain Web applications can be built through Vue. When developing Vue, network settings are an important link because it is related to the user experience and usability of the application.

In terms of Vue's network settings, we can use the following methods to configure and optimize:

1. Use axios for network requests

axios is a Promise-based HTTP client for sending asynchronous request data. In Vue, we can use axios to make network requests and process the response data accordingly.

1. Install axios

We can install axios through npm or yarn:

npm install axios --save
或
yarn add axios

2. Introduce axios into Vue

We can install axios in Vue Use the import command to introduce axios in the component:

import axios from 'axios'

3. Initiate a network request

We can use axios’ get or postMethod to initiate a network request:

//GET请求
axios.get('/user?id=123')
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  });

//POST请求
axios.post('/user', {
    id: 123,
    name: 'Tom',
    age: 18
  })
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  });

2. Set up the Vue network request interceptor

Using the network request interceptor in Vue can uniformly process network requests and reduce code redundancy. We can set the Vue network request interceptor in the following ways:

1. Set it in main.js

We set the Vue network request interceptor in main.js, the code is as follows:

import axios from 'axios'
import VueAxios from 'vue-axios'
 
Vue.use(VueAxios, axios)
 
axios.interceptors.request.use(config => {
      //拦截请求，并进行相应的处理
    console.log('请求已拦截');
    return config;
}, err => {
    console.log('请求拦截失败');
    return Promise.reject(err);
});

2. Using interceptors in Vue components

We can also use network request interceptors in Vue components. The code is as follows:

import axios from 'axios'
 
export default {
    data () {
        return {
            users: []
        }
    },
    created () {
        axios.interceptors.request.use(function (config) {
            //拦截请求，并进行相应的处理
            console.log('请求已拦截');
            return config;
        }, function (err) {
            console.log('请求拦截失败');
            return Promise.reject(err);
        });
 
        axios.get('/users')
            .then(response => {
                this.users = response.data
            })
            .catch(error => {
                console.log(error)
            });
    }
}

3. Use the Vue plug-in to network Request caching

In Vue, we can use plug-ins to cache network request data to improve network request speed and user experience. We can cache network request data in the following ways:

1. Install vue-ls

We can install vue-ls through npm or yarn:

npm install vue-ls --save
或
yarn add vue-ls

2 .Introduce vue-ls in main.js

We need to introduce vue-ls in main.js and set the relevant parameters of the cache. The code is as follows:

import Vue from 'vue'
import VueLS from 'vue-ls'
 
Vue.use(VueLS, options)
 
const options = {
  namespace: 'vuejs__', // key键前缀
  name: 'ls', // 命名Vue变量.[ls]或this.[$ls],
  storage: 'local' // 存储名称: session, local, memory
}

3. Use the plug-in to Cache network request data

We can use plug-ins in Vue components to cache network request data. The code is as follows:

import axios from 'axios'
 
export default {
    data () {
        return {
            users: []
        }
    },
    created () {
        this.users = this.$ls.get('users')
        if (!this.users) {
            axios.get('/users')
                .then(response => {
                    this.users = response.data
                    this.$ls.set('users', this.users, 60 * 60 * 1000) //设置缓存时间为1小时
                })
                .catch(error => {
                    console.log(error)
                });
        }
    }
}

Summary

Network settings are important for Vue development One of the links. Through the above introduction, we can use axios to make network requests, use the network request interceptor to uniformly process network requests, and use the Vue plug-in to cache network request data to improve the user experience and usability of the application. At the same time, we can also optimize accordingly based on our own needs.
