Socket.IO 客户端 .js 文件在哪里? [英] Where is the Socket.IO client-side .js file located?

问题描述

我正在尝试让 socket.io(节点库)工作.

I am trying to get socket.io (Node library) to work.

我的服务器端 js 正在运行，它正在监听.socket.io 网站简单说明:

I have the server-side js working, and it is listening. The socket.io website states simply:

<script src="/socket.io/socket.io.js"></script>
<script>
  var socket = io.connect('http://localhost');
  socket.on('news', function (data) {
    console.log(data);
    socket.emit('my other event', { my: 'data' });
  });
</script>

这很好，但是，我要导入什么 JS 文件！?！

This is nice, however, what JS file am I importing!?!

进入node_modules目录，通过npm安装socket.io，socket.io/lib/里面是socket.io.js文件.但是，这是服务器端的(使用短语 require()，这会在客户端出错).

I went into the node_modules directory, where I installed socket.io through npm, and inside socket.io/lib/ is socket.io.js file. However, this is server-side (uses the phrase require(), which errors on the client).

我花了一个小时环顾四周，但我无法让任何客户端 .js 文件工作.

I have spent an hour looking around and I can't get any client .js file to work.

我错过了什么?

推荐答案

我最终设法自己回答了这个问题.

I managed to eventually answer this for myself.

socket.io 入门页面在这方面不清楚，但我发现 socket.io 的服务器端自动将 .js 文件托管在起始节点上，在文档中指定的目录中:

The socket.io getting started page isn't clear on this, but I found that the server side of socket.io automatically hosts the .js file on starting node, in the directory specified in the documentation:

"/socket.io/socket.io.js"

因此，无论您的网络应用程序结构如何，您都只需指向此网址，它就可以工作.

So you literally just point to this url regardless of your web app structure, and it works.
