Node.js - Socket.io客户端文件不由基本节点Web服务器提供 [英] Node.js - Socket.io client file not being served by basic node web server

问题描述

我是Node.js和Socket.io的新手。我已经构建了一个非常基本的Web服务器，但是在使用它时，我无法加载socket.io客户端文件（我得到了404）。

I m very new to Node.js and Socket.io. I have built a very basic web server however when using it, I am unable to load the socket.io client file (I get a 404).

我正在尝试使用此客户端代码：

I am trying to use this client side code:

<script src="/socket.io/socket.io.js"></script>

我的理解是Node应该选择并解决它？它在一个更简单的Web服务器示例上。

My understanding is that Node should pick this up and resolve it? It does on a much simpler web server example.

我的Web服务器示例未解析如下：

My web server example where it is NOT resolved is as follows:

var server = http.createServer(function (request, response) {

    console.log('request starting...');

    var filePath = '.' + request.url;
    if (filePath == './')
        filePath = './index.html';

    var extname = path.extname(filePath);
    var contentType = 'text/html';
    switch (extname) {
        case '.js':
            contentType = 'text/javascript';
            break;
        case '.css':
            contentType = 'text/css';
            break;
    }

    path.exists(filePath, function(exists) {

        if (exists) {
            fs.readFile(filePath, function(error, content) {
                if (error) {
                    response.writeHead(500);
                    response.end();
                }
                else {
                    response.writeHead(200, { 'Content-Type': contentType });
                    response.end(content, 'utf-8');
                }
            });
        }
        else {
            response.writeHead(404);
            response.end();
        }
    });

我解决的网络服务器代码如下：

My web server code where it DOES resolve is as follows:

app.listen(8080);

function handler (req, res) {
  fs.readFile(__dirname + '/index.html',
  function (err, data) {
    if (err) {
      res.writeHead(500);
      return res.end('Error loading index.html');
    }

    res.writeHead(200);
    res.end(data);
  });
}

任何人都可以告知导致它无法提供socket.io文件的原因使用第一个Web服务器示例的客户端？

Can anyone advise on what is causing it not serve the socket.io file on the client using the first web server example?

最好的问候，Ben。

推荐答案

您可能在另一个端口上运行Socket.IO，因此请按以下格式包含该文件：

You are probably running Socket.IO on a different port, so include the file in the following format:

server：port /socket.io/socket.io.js

server:port/socket.io/socket.io.js
