3.安装axios

3.1.npm安装axios

npm install --save axios

vue(32) : win10创建vue2基础前端框架,前端,vue.js,前端框架,javascript,vue项目2

3.2.项目根目录创建[vue.config.js]文件, 内容如下

'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://127.0.0.1:33001', // 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()
  }
}

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

/*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.errCode !== 0) {
			Message({
				message: res.errMessage || '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

import request from '@/util/request'
 
 
export function test() {
  return request({
    url: '/test/2',
    method: 'get'
  })
}

4.2. App.vue替换

<template>
	<div>
		{{ testData }}
	</div>
</template>

<script>
	import {
		test,
	} from '@/api/test'

	export default {
		name: 'app',
		data() {
			return {
				testData: null
			}
		},
		created() {
			this.t1()
		},
		methods: {
			t1() {
				test().then(response => {
					console.log(response)
					this.testData = response.msg
				})
			}
		}
	}
</script>

<style>
</style>

4.3.后台接口需要返回以下内容

接口地址为： http://127.0.0.1:33001/test/2

    @GetMapping("/test/2")
    public Object test2() {
        Map<String, Object> res = new HashMap<>();
        res.put("code", 200);
        res.put("errCode", 0);
        res.put("errMessage", "测试错误");
        res.put("msg", "SUCCESS");
        return res;
    }

内容如下

{
"msg": "SUCCESS",
"code": 200,
"errCode": 0,
"errMessage": "测试错误"
}

5.启动

npm run serve

vue(32) : win10创建vue2基础前端框架,前端,vue.js,前端框架,javascript,vue项目2

6.编译

npm run build

7.部署

dist里面的文件放到nginx目录下

nginx.conf添加以下配置

		location /test {
            proxy_pass http://127.0.0.1:33001;
            proxy_set_header   X-Forwarded-Proto $scheme;
            proxy_set_header   Host              $http_host;
            proxy_set_header   X-Real-IP         $remote_addr;
        }
