1.進入Vue專案的config/index.js 檔案。

未配置之前是這樣的：

module.exports = {
  dev: {

    // Paths
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',
    proxyTable: {},

    // Various Dev Server settings
    host: 'localhost', // can be overwritten by process.env.HOST
    port: 8080, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined
    autoOpenBrowser: false,
    errorOverlay: true,
    notifyOnErrors: true,
    poll: false, // https://webpack.js.org/configuration/dev-server/#devserver-watchoptions-
 

配置：注意在Vue專案中修改配置檔案之後一定要 npm run dev 重啟專案。

'use strict'
// Template version: 1.3.1
// see http://vuejs-templates.github.io/webpack for documentation.

const path = require('path')

module.exports = {
  dev: {

    // Paths
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',
    proxyTable: {
    	'/api':{
    	target: 'http://192.168.0.36:8080', //這裡面是你要訪問的IP地址
        changeOrigin: true, //開啟代理
        pathRewrite:{
        	'/api': '/api'
        }
    	}
    },

    // Various Dev Server settings
    host: '192.168.0.36', // can be overwritten by process.env.HOST
    port: 8081, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined
    autoOpenBrowser: false,
    errorOverlay: true,
    notifyOnErrors: true,
    poll: false,
