eclipse运行我的节点js project.Following js文件正常工作,但h1标签不工作.我只能看到一个纯文本.我在运行时得到这个异常帮助我出.
var http = require('http');
http.createServer(function (request,response) {
response.writeHead(200,{'Content-Type': 'text/html'});
response.end('<html><body><h1>Home</h1> URL was: ' + request.url + '</body></html>');
}).listen(3000,'localhost');
console.log('Server running at http://localhost:3000/');
例外

解决方法
错误：听EADDRINUSE
这个错误意味着您已经有另一个进程监听端口3000.
Here is how to find out which process it is on windows
C:\> netstat -a -b (add -n to stop it trying to resolve hostnames,which will make it a lot faster) Edit: +1 for Dane's recommendation for TCPView. Looks very useful! -a Displays all connections and listening ports. -b Displays the executable involved in creating each connection or listening port. In some cases well-known executables host multiple independent components,and in these cases the sequence of components involved in creating the connection or listening port is displayed. In this case the executable name is in [] at the bottom,on top is the component it called,and so forth until TCP/IP was reached. Note that this option can be time-consuming and will fail unless you have sufficient permissions. -n Displays addresses and port numbers in numerical form.
