无意在ts官方网站的“起步”里看到一张图片，出于好奇点进去看了一下

下面有一段代码是这样的：

import * as express from "express";
import * as request from "request";
import sha1 = require("sha1");

let app = express(); 

// Insert metadata
let appId = '';             // Insert your appId
let appsecret = '';         // insert your appsecret
let url = '';               // insert host url, e.g. http://wxapp.azurewebsites.net/
let nonceStr = '';          // insert any string

// define an interface containing params for wx.config
interface configObj {
    appId: string,
    timestamp: string,
    nonceStr: string,
    signature: string
}

// handshake with WeChat server and get signature for wx.config
function getWXConfig(cb) {
    request.get('https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid='+appId+'&secret='+appsecret, (err, res, body) => {
        request.get('https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token='+JSON.parse(body).access_token+'&type=jsapi', (err, res, body) => {
            let ticket = JSON.parse(body).ticket;
            let o: configObj = {
                appId: appId,
                nonceStr: nonceStr, 
                timestamp: new Date().getTime() / 1000 + '',
                signature: ''
            };
            o.signature = sha1('jsapi_ticket='+ticket+'&noncestr='+o.nonceStr+'&timestamp='+o.timestamp+'&url='+url).toString();
            cb(o);
        });
    });
}

app.engine('.html', require('ejs').__express);          // set up ejs as view engine
app.set('views', __dirname + '/views');                 // set views dir
app.set('view engine', 'html');                         // use .html for ejs files
app.use(express.static('public'))                       // expose assets in /public
app.get('/', function (req, res) {
    getWXConfig(config => {
        // handshake with WeChat server and render index.html with the returned signature
        res.render('index', {
            appId: config.appId,
            timestamp: config.timestamp,
            nonceStr: config.nonceStr,
            signature: config.signature,
        });
    })
});
app.listen(8080);

里面包括了如何发送get请求和创建http的监听

某度怎么搜的搜不到的结果，今天无意之间发现了，分享出来希望能帮助到使用TypeScript的开发者。
