1.GET模块：_get.js

/** * Created by jinx on 7/7/17. */var http = require('http');module.exports = {    /**    * 测试获取所有的区域    * /    locations: function (cb) {        http.get('http://wx.xx.com/locations', function (res) {            res.setEncoding('utf8');            var rawData = '';            res.on('data', function (chunk) {                rawData += chunk;            });            res.on('end', function () {                try {                    const parsedData = JSON.parse(rawData);                    console.log(parsedData);                    cb(parsedData);                } catch (e) {                console.error(e.message);                    cb('error')；                }            });        });    }}

2.路由端调用：routes.js

var _get = require('../modules/_get');module.exports = function (app, _dirpath) {    app.get('/get', function (req, res) {        _get.locations(function (data) {            res.writeHead(200, {"Content-Type": "application/json"});            res.write(JSON.stringify(data));            res.end();        });    });}

3.服务启动入口：

/** * Created by jinx on 7/3/17. */var express = require('express')    , routes = require('./routes/routes')    , http = require('http');var app = express();app.set('port', process.env.PORT || 3000);app.set('views', __dirname + '/views');app.set('view engine', 'ejs');/** * 静态文件目录 */app.use(express.static('public'));/** * 加载路由配置 */routes(app,__dirname);/** * 启动服务器 */http.createServer(app).listen(app.get('port'), function(){  console.log("服务器已经启动了" + app.get('port'));});

5.调用js get.js：

/** * Created by jinx on 7/7/17. */var _i;$(function () {    _i = layer.open({type: 2});    $.ajax({        url: '/get',        type: 'get',        dataType: 'json',        success: function (res) {            if (res != null)                layer.close(_i);            new Vue({                el: '.main',                data: {items: res.params}            });        }    })})

6.调用页面 get.html：

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />    <title>http get</title>    <link href="https://cdn.bootcss.com/layer/3.0.1/mobile/need/layer.min.css" rel="stylesheet">    <link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap-theme.min.css" rel="stylesheet">    <link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">    <link href="css/style.css" rel="stylesheet"></head><body><table class="table main">    <thead>    <tr>        <td>ID</td>        <td>Name</td>    </tr>    </thead>    <tbody>    <tr v-for="item in items" >        <td v-text="item.id"></td>        <td v-text="item.name"></td>    </tr>    </tbody></table><a href="/" class="btn btn-info width-100">返回首页</a><script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.js"></script><script src="https://cdn.bootcss.com/bootstrap/3.3.7/js/bootstrap.min.js"></script><script src="https://cdn.bootcss.com/layer/3.0.1/mobile/layer.js"></script><script src="https://cdn.bootcss.com/vue/2.3.4/vue.min.js"></script><script src="js/get.js"></script></body></html>
