Socket.IO客户端.js文件位于何处？ [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.

我让服务器端的js工作，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，我导入的JS文件是什么！？！

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

我进入了node_modules目录，在那里我通过npm安装了socket.io，在中，socket.io / lib / 是 socket.io.js 文件。但是，这是服务器端（使用短语 require（），客户端上的错误）。

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，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.

我缺少什么？

推荐答案

我最终为自己解决了这个问题。

I managed to eventually answer this for myself.

socket.io入门页面不是清楚这一点，但我发现socket.io的服务器端自动托管起始节点上的.js文件，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"

所以你无论您的网络应用程序结构如何，只需指向此网址，它就可以正常工作。

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