NodeJS服务器上的Response.write（）或.toString（）（错误？）

Question

I am a trying to make a small web server for testing. 我正在尝试制作一个小型Web服务器进行测试。 I made it with NodeJS. 我用NodeJS制作的。 But something unexpected happened. 但是出乎意料的事情发生了。 The webpage passed by the NodeJS server couldn't be displayed properly. 由NodeJS服务器传递的网页无法正确显示。 But the webpage worked perfectly when I used php+Apache. 但是当我使用php + Apache时，该网页运行完美。 When I opened the source code received at my client side, there are no observable difference. 当我打开在客户端收到的源代码时，没有明显的区别。 Here is my code: 这是我的代码：

Server.js Server.js

var http = require('http');
var fs = require('fs');
var url = require('url');
var Max = 30;
var port = process.argv[2];

var server = http.createServer( function (request, response) {
    var pathname = url.parse(request.url).pathname; if (pathname == "") pathname = "index.html";
    console.log("Request for " + pathname + " received.");
    fs.readFile(pathname.substr(1), function (err, data) {
            if (err) {
                    console.log(err);
                    response.writeHead(404, {'Content-Type': 'text/html'});
            } else {
                    response.writeHead(200, {'Content-Type': 'text/html'});
                    response.write(data.toString());
            }
            response.end();
    });
}).listen(port);

console.log('Server running at http://127.0.0.1:8081/');


var sockets = {}, nextSocketId = 0;
server.on('connection', function (socket) {
    var socketId = nextSocketId++;
    sockets[socketId] = socket;
    console.log('socket', socketId, 'opened');

    socket.on('close', function () {
            console.log('socket', socketId, 'closed');
            delete sockets[socketId];
    });

    socket.setTimeout(4000);
});

function anyOpen(array) {
    for (var ele in array) {
            if (ele) return true;
    }
    return false;
}


(function countDown (counter) {
    console.log(counter);
    if (anyOpen(sockets)) {
            return setTimeout(countDown, 1000, Max);
    } else if (counter > 0 ) {
            return setTimeout(countDown, 1000, counter - 1);
    };
    server.close(function () { console.log('Server closed!'); });
    for (var socketId in sockets) {
            console.log('socket', socketId, 'destroyed');
            sockets[socketId].destroy();
    }
})(Max);

Users should be able to access the Chatroom2-0.php after login. 登录后，用户应该可以访问Chatroom2-0.php。 The login functionality is also ok. 登录功能也可以。 But when I entered the Chatroom2-0.php, I got a String, next to my textbox. 但是，当我进入Chatroom2-0.php时，在文本框旁边有一个字符串。

'; '; else { header("Location: /login/index.html"); else {header（“ Location：/login/index.html”）; die(); 死（）; } ?> }？>

I noticed that the string is part of my php code in the file. 我注意到该字符串是文件中我的php代码的一部分。 I don't know what's happening. 我不知道发生了什么 I think this might have something to do with the response.write() or the data.toString() function. 我认为这可能与response.write（）或data.toString（）函数有关。 Maybe the function changed something in my coding? 也许函数在我的编码中做了些改变？ How could I solve this problem. 我该如何解决这个问题。

Anyway, I appreciate for any help given. 无论如何，我感谢您给予的任何帮助。

The problem is that you are trying to run php code on a nodejs server. 问题是您正在尝试在nodejs服务器上运行php代码。 There is no solution to this, as node is not a php interpreter, so it sees everything as html text; 没有解决方案，因为node不是php解释器，所以它将所有内容视为html文本； thus your php code appearing on the page. 因此，您的php代码出现在页面上。 You need to create an entirely different html for the node project. 您需要为节点项目创建完全不同的html。
