3.安装axios

3.1.npm安装axios

复制代码
npm install --save axios

3.2.项目根目录创建[vue.config.js]文件, 内容如下

复制代码
'use strict'
const path = require('path')
 
function resolve(dir) {
  return path.join(__dirname, dir)
}
 
const port = process.env.port || process.env.npm_config_port || 9527 // dev port
const name =  '测试' // page title
 
// All configuration item explanations can be find in https://cli.vuejs.org/config/
module.exports = {
  /**
   * You will need to set publicPath if you plan to deploy your site under a sub path,
   * for example GitHub Pages. If you plan to deploy your site to https://foo.github.io/bar/,
   * then publicPath should be set to "/bar/".
   * In most cases please use '/' !!!
   * Detail: https://cli.vuejs.org/config/#publicpath
   */
  publicPath: '/',
  outputDir: 'dist',
  assetsDir: 'static',
  lintOnSave: process.env.NODE_ENV === 'development',
  productionSourceMap: false,
  devServer: {
    port: port,
    open: true,
    overlay: {
      warnings: false,
      errors: true
    },
    proxy: {
      // 代理test开头的uri
      '/test': {
        target: 'http://192.168.1.1:8080', // 后端地址
        // target: 'localhost:8080/manage', // 原始地址
        changeOrigin: true, // 开启代理,在本地创建一个虚拟服务端
        pathRewrite: {
          '^/test': '/test'
        }
      }
    }
    //before: require('./mock/mock-server.js')
  },
  configureWebpack: {
    // provide the app's title in webpack's name field, so that
    // it can be accessed in index.html to inject the correct title.
    name: name,
    resolve: {
      alias: {
        '@': resolve('src')
      }
    }
  },
  chainWebpack(config) {
    // it can improve the speed of the first screen, it is recommended to turn on preload
    // it can improve the speed of the first screen, it is recommended to turn on preload
    config.plugin('preload').tap(() => [
      {
        rel: 'preload',
        // to ignore runtime.js
        // https://github.com/vuejs/vue-cli/blob/dev/packages/@vue/cli-service/lib/config/app.js#L171
        fileBlacklist: [/\.map$/, /hot-update\.js$/, /runtime\..*\.js$/],
        include: 'initial'
      }
    ])
 
    // when there are many pages, it will cause too many meaningless requests
    config.plugins.delete('prefetch')
 
    // set svg-sprite-loader
    config.module
      .rule('svg')
      .exclude.add(resolve('src/icons'))
      .end()
    config.module
      .rule('icons')
      .test(/\.svg$/)
      .include.add(resolve('src/icons'))
      .end()
      .use('svg-sprite-loader')
      .loader('svg-sprite-loader')
      .options({
        symbolId: 'icon-[name]'
      })
      .end()
 
    config
      .when(process.env.NODE_ENV !== 'development',
        config => {
          config
            .plugin('ScriptExtHtmlWebpackPlugin')
            .after('html')
            .use('script-ext-html-webpack-plugin', [{
            // `runtime` must same as runtimeChunk name. default is `runtime`
              inline: /runtime\..*\.js$/
            }])
            .end()
          config
            .optimization.splitChunks({
              chunks: 'all',
              cacheGroups: {
                libs: {
                  name: 'chunk-libs',
                  test: /[\\/]node_modules[\\/]/,
                  priority: 10,
                  chunks: 'initial' // only package third parties that are initially dependent
                },
                elementUI: {
                  name: 'chunk-elementUI', // split elementUI into a single package
                  priority: 20, // the weight needs to be larger than libs and app or it will be packaged into libs or app
                  test: /[\\/]node_modules[\\/]_?element-ui(.*)/ // in order to adapt to cnpm
                },
                commons: {
                  name: 'chunk-commons',
                  test: resolve('src/components'), // can customize your rules
                  minChunks: 3, //  minimum common number
                  priority: 5,
                  reuseExistingChunk: true
                }
              }
            })
          // https:// webpack.js.org/configuration/optimization/#optimizationruntimechunk
          config.optimization.runtimeChunk('single')
        }
      )
  }
}

代理后端配置如下, 三个test改成相同的uri前缀即可, uri该签注会代理到后端

proxy: {

// 代理test开头的uri

'/test': {

target: 'http://192.168.1.1:8080', // 后端地址

changeOrigin: true, // 开启代理,在本地创建一个虚拟服务端

pathRewrite: {

'^/test': '/test'

}

}

}

3.3.src下创建util目录, util文件夹下创建request.js, 内容如下

const res = response.data

这个需要根据后端接口格式修改

复制代码
/*引入axios*/
import axios from 'axios'
import { MessageBox, Message } from 'element-ui'
 
const request = axios.create({
    baseURL: '', // 基础路径,将统一的部分全部封装
    withCredentials: true // 表示请求可以携带cookie
})
 
axios.defaults.headers['Content-Type'] = 'application/x-www-form-urlencoded'
 
 
// response interceptor
request.interceptors.response.use(
  /**
   * If you want to get http information such as headers or status
   * Please return  response => response
  */
 
  /**
   * Determine the request status by custom code
   * Here is just an example
   * You can also judge the status by HTTP Status Code
   */
  response => {
    const res = response.data
    // if the custom code is not 20000, it is judged as an error.
    if (res.code !== '0') {
      Message({
        message: res.message || 'Error',
        type: 'error',
        duration: 3 * 1000
      })
      // return Promise.reject(new Error(res.message || 'Error'))
      return null
    } else {
      return res
    }
  },
  error => {
    console.log('err' + error) // for debug
    Message({
      message: error.message,
      type: 'error',
      duration: 5 * 1000
    })
    return Promise.reject(error)
  }
)
 
 
//前端采用export.default,在写后端代码时用module.export
export default request

4.创建测试调用http

4.1.src下创建api目录, api下创建test.js, 内容如下

复制代码
import request from '@/util/request'
 
export function add(data) {
  return request({
    url: '/my-boke',
    headers: { 'Content-Type': 'application/json' },
    method: 'post',
    data
  })
}
 
export function update(data) {
  return request({
    url: '/my-boke',
    headers: { 'Content-Type': 'application/json' },
    method: 'put',
    data
  })
}
 
export function del(data) {
  return request({
    url: '/my-boke',
    method: 'delete',
    params: data
  })
}
 
export function env() {
  return request({
    url: '/fsa/env',
    method: 'get'
  })
}

4.2. vue.js调用http

bash 复制代码
<template>

</template>

<script>
	import {
		add,
		update,
		del,
		env
	} from '@/api/fsa'

	export default {
		name: 'app',
		data() {
			return {

			}
		},
		created() {
			this.t1()
		},
		methods: {
			t1() {
				env().then(response => {
					console.log(response)
				})
			}
		}
	}
</script>

<style>
	#app {
		font-family: 'Avenir', Helvetica, Arial, sans-serif;
		-webkit-font-smoothing: antialiased;
		-moz-osx-font-smoothing: grayscale;
		text-align: center;
		color: #2c3e50;
		margin-top: 60px;
	}
</style>

5.启动

复制代码
npm run serve

6.编译

报错, 待解决
