javascript - 如何解决错误：使用nodejs时监听EADDRINUSE？(How to fix Error: listen EADDRINUSE while using nodejs?)

Question

If I run a server with the port 80, and I try to use xmlHTTPrequest i get this error: Error: listen EADDRINUSE(如果我使用端口80运行服务器，并且尝试使用xmlHTTPrequest，则会收到此错误： Error: listen EADDRINUSE)

Why is it problem for nodejs, if I want to do a request, while I run a server on the port 80?(在80端口上运行服务器时，如果要发出请求，为什么nodejs会出现问题？) For the webbrowsers it is not a problem: I can surf on the internet, while the server is running.(对于网络浏览器而言，这不是问题：服务器运行时，我可以在Internet上冲浪。) The server is:(服务器是：) net.createServer(function (socket) { socket.name = socket.remoteAddress + ":" + socket.remotePort; console.log('connection request from: ' + socket.remoteAddress); socket.destroy(); }).listen(options.port); And the request:(并要求：) var xhr = new XMLHttpRequest(); xhr.onreadystatechange = function() { sys.puts("State: " + this.readyState); if (this.readyState == 4) { sys.puts("Complete. Body length: " + this.responseText.length); sys.puts("Body: " + this.responseText); } }; xhr.open("GET", "http://mywebsite.com"); xhr.send();   ask by Danny Fox translate from so
