NodeJs测试

一：效果

打开两个浏览器页面，
第一个浏览器页面输入：http://localhost:8888/upload
第一个浏览器页面输入：http://localhost:8888/start

然后，依次点击进入页面。

隔10秒后，两个页面会依次打开

二：环境

windows7、nodejs

三：代码

1.目录

2.运行文件 index.js

1 var server = require("./server01");
2 var router = require(‘./router‘);
3 var requestHandlers = require(‘./requestHandlers‘);
4
5 var handle = {}
6 handle["/"] = requestHandlers.start;
7 handle["/start"] = requestHandlers.start;
8 handle["/upload"] = requestHandlers.upload;
9 server.start(router.route, handle);

3.路由文件 router.js

 1 function route(handle, pathname){
 2     console.log(‘About to route a request for ‘ + pathname );
 3     if(typeof handle[pathname] === ‘function‘ ){
 4        return handle[pathname]();
 5     }else{
 6       console.log(‘No request handler found for ‘ + pathname);
 7       return ‘404 not found‘;
 8     }
 9 }
10
11 exports.route = route;

4.server01.js

 1 var http = require("http");
 2 var url = require(‘url‘);
 3
 4 function start(route, handle){
 5     function onRequest(req, res){
 6       console.log(‘Star : ‘);
 7       var pathname = url.parse(req.url).pathname;
 8
 9       console.log(‘Request for \‘‘ + pathname + ‘\‘  received‘);
10
11       var content = route(handle, pathname);
12
13       res.writeHead(200, {‘Content-Type‘ : ‘text/plain‘});
14       res.end(content);
15     }
16
17     http.createServer(onRequest).listen(8888,‘127.0.0.1‘);
18 }
19
20 exports.start = start;

4.requestHandlers.js

 1 function start(){
 2   console.log(" Request Handler ‘start‘ was called  ");
 3     function sleep(milliSeconds){
 4       var startTime = new Date().getTime();
 5       while(new Date().getTime() < startTime + milliSeconds);
 6     }
 7    sleep(10000);
 8   return "hello Start";
 9 }
10
11 function upload(){
12   console.log(" Request Handler ‘upload‘ was called  ");
13   return "hello Upload";
14 }
15
16 exports.start = start ;
17 exports.upload = upload ;
