纯Node.js服务器上的Unity3D Webplayer扩展(Unity3D Webplayer extension on pure Node.js server)

我无法在node.js服务器上运行Unity3D应用程序。 它说“无法下载数据文件”。 我认为这是因为MIME类型。 这是我的代码。 我是Javascript和Node.js的新手，对不起。

Server.js：

var http = require("http"); var url = require('url'); var fs = require('fs'); var io = require('socket.io'); var five = require("johnny-five"),board, led, button; board = new five.Board(); board.on("ready", function() { button = new five.Button(2); }); var server = http.createServer(function(request, response){ console.log('Connection'); var path = url.parse(request.url).pathname; switch(path){ case '/': response.writeHead(200, {'Content-Type': 'text/html'}); response.write('hello world', function(err) { response.end(); }); break; case '/index.html': fs.readFile(__dirname + path, function(error, data){ if (error){ response.writeHead(404); response.write("opps this doesn't exist - 404"); } else{ response.writeHead(200, {"Content-Type": "text/html"}); response.write(data, function(err) { response.end(); }); } }); break; default: response.writeHead(404); response.write("opps this doesn't exist - 404", function(err) { response.end(); }); break; } }); server.listen(8001); var ios = io.listen(server); ios.listen(server); ios.sockets.on('connection', function (socket) { if (board.isReady) { button.on("down",function(){ console.log("down"); socket.emit('news', { hello: 'world' }); }); socket.on('toggleLed', function(data){ led = new five.Led(13); led.strobe(1000); }); setInterval(function(){ socket.emit('date', {'date': new Date()}); }); socket.on('client_data', function(data){ process.stdout.write(data.letter); }); } });

index.html的：

感谢您的帮助。

I can't run my Unity3D applications on my node.js server. It says "failed to download data file". I think it's because of MIME types. Here are my codes. I'm new to Javascript and Node.js, sorry for that.

Server.js:

var http = require("http"); var url = require('url'); var fs = require('fs'); var io = require('socket.io'); var five = require("johnny-five"),board, led, button; board = new five.Board(); board.on("ready", function() { button = new five.Button(2); }); var server = http.createServer(function(request, response){ console.log('Connection'); var path = url.parse(request.url).pathname; switch(path){ case '/': response.writeHead(200, {'Content-Type': 'text/html'}); response.write('hello world', function(err) { response.end(); }); break; case '/index.html': fs.readFile(__dirname + path, function(error, data){ if (error){ response.writeHead(404); response.write("opps this doesn't exist - 404"); } else{ response.writeHead(200, {"Content-Type": "text/html"}); response.write(data, function(err) { response.end(); }); } }); break; default: response.writeHead(404); response.write("opps this doesn't exist - 404", function(err) { response.end(); }); break; } }); server.listen(8001); var ios = io.listen(server); ios.listen(server); ios.sockets.on('connection', function (socket) { if (board.isReady) { button.on("down",function(){ console.log("down"); socket.emit('news', { hello: 'world' }); }); socket.on('toggleLed', function(data){ led = new five.Led(13); led.strobe(1000); }); setInterval(function(){ socket.emit('date', {'date': new Date()}); }); socket.on('client_data', function(data){ process.stdout.write(data.letter); }); } });

Index.html:

Thank you for your help.

最满意答案

我发现这是因为这个服务器代码。

var server = http.createServer(function(request, response){ console.log('Connection'); var path = url.parse(request.url).pathname; switch(path){ case '/': response.writeHead(200, {'Content-Type': 'text/html'}); response.write('hello world', function(err) { response.end(); }); break; case '/index.html': fs.readFile(__dirname + path, function(error, data){ if (error){ response.writeHead(404); response.write("opps this doesn't exist - 404"); } else{ response.writeHead(200, {"Content-Type": "text/html"}); response.write(data, function(err) { response.end(); }); } }); break; default: response.writeHead(404); response.write("opps this doesn't exist - 404", function(err) { response.end(); }); break; } });

我按照这个代码找到了解决方案。

I found that it is because of this server code.

var server = http.createServer(function(request, response){ console.log('Connection'); var path = url.parse(request.url).pathname; switch(path){ case '/': response.writeHead(200, {'Content-Type': 'text/html'}); response.write('hello world', function(err) { response.end(); }); break; case '/index.html': fs.readFile(__dirname + path, function(error, data){ if (error){ response.writeHead(404); response.write("opps this doesn't exist - 404"); } else{ response.writeHead(200, {"Content-Type": "text/html"}); response.write(data, function(err) { response.end(); }); } }); break; default: response.writeHead(404); response.write("opps this doesn't exist - 404", function(err) { response.end(); }); break; } });

I followed this code and found the solution.
