Jinx_Q 人气:0
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'));
});
4.项目目录如下：
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" />

<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="/" rel="external nofollow" class="btn btn-info width-100">返回首页</a>
