Question

我对Node.js很新。我正在探索路由（代码如下所示）。当客户端请求本地页面（在本例中为socket.html）时，客户端不会获取路由页面，而是显示空白页面。我没有看到Node.js框架的任何错误。谢谢你看。

var http = require("http");
var url = require('url');
var fs = require('fs');
var io = require('socket.io');
var path = '';
var server = http.createServer(function(request, response){
    console.log('Connection');
    path = url.parse(request.url).pathname;
    console.log(path);

    switch(path){
        case '/':
            response.writeHead(200, {'Content-Type': 'text/html'});
            response.write('hello world');
            break;
        case '/socket2.html':
            fs.createReadStream(__dirname + path, function(error, data){
                if (error) {
                    console.log('there is error for ' + path);
                    response.writeHead(404);
                    response.write("opps this doesn't exist - 404");
                }
                else {
                    console.log('sending file ' + data);
                    response.writeHead(200, { 'Content-Type': 'text/html' });
                    response.write(data);
                }
            });
            break;
        default:
            response.writeHead(404);
            response.write("opps this doesn't exist - 404");
            break;
    }
    console.log('send reponse');
    response.end();
});

console.log('Listening');
server.listen(8001);

console.log('Socket started for ' + path);
io.listen(server);

// socket2.html页面内容

<!DOCTYPE html>
<html>

    <head>
        <title></title>  
        <script src="node_modules/socket.io/node_modules/socket.io-client/dist/socket.io.js"></script>
    </head>


    <body>
        <script>
            var socket = io.connect();
        </script>
        <div>This is our socket2.html file</div>
    </body>
</html>

//实际页面内容

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META http-equiv="Content-Type" 
content="text/html; charset=windows-1252"></HEAD>
<BODY></BODY></HTML>

请查看catberry.js或express框架。

我确信没有人使用节点内置HTTP服务器和切换操作符解决此任务。也许您只需要一个单独的Web服务器，如nginx，它提供静态服务并将一些位置传递给node.js应用程序以呈现一些动态页面。

如何将页面返回到Node.js客户端？
