Node.js，Socket.io:如何获取客户端浏览器语言? [英] Node.js, Socket.io: How to get client browser-language?

问题描述

我正在尝试使用 socket.io 和 node.js 获取用户使用的语言，以便为播放视频提供正确的声音文件.我是node.js和socket.io的初学者.我在客户端使用"navigator.language"获得了该语言，并希望在与socket.io连接/握手时将其发送.

I am trying to get the language the user uses in order to serve the right sound files for a playing video, using socket.io and node.js. I am a total beginner with node.js and socket.io. I got the language on client side with "navigator.language" and wanted to send it when connecting/handshaking to socket.io.

var language = navigator.language;
var socket = io.connect('http://localhost:1337', { query: language });

在服务器端:

io.set('authorization', function(handshakeData, cb) {
    console.log(handshakeData.query);
    cb(null, true);});

但是我得到的是:

{'en-US': 'undefined', t: '1396002389530'}

我猜第二个属性"t"是已添加的握手ID.但是，如何访问"en-US"?

I guess the second attribute "t" is the handshake ID that has been added. But how do I access 'en-US'?

我的第二种方法是使用模块"locale"( https://github.com/jed/locale )，但是当我使用它时，我总是使用相同的语言，因此我发现它总是可以找到SERVER的语言.我以为我是在新客户端请求页面并发送其HTTP标头时在请求/响应处理程序中使用它的.

My second approach was to use the module "locale" (https://github.com/jed/locale), but when I used that, I always got the same language, so I figured that it always finds the SERVER's language. I thought I use it in the request/response handler, when a new client requests the page and sends its http header.

var handler = function(req, res) {
    lang = new locale.Locales(req.headers["accept-language"]);
    lang=lang.best(supported);
    console.log(pf);
}

希望您能得到我正在尝试做的事情，并且也许知道更好的解决方案.预先谢谢你.

I hope you get what I am trying to do and maybe know a better solution. Thank you in advance.

推荐答案

您快到了.这样做:

var socket = io.connect('http://localhost:1337', { lang: language });

因为查询是保留对象，所以代替了 {query:language} .

Instead of {query: language} because query is a reserved object.

您可以通过执行以下操作来访问它:

And you can access this by doing this:

io.set('authorization', function(handshakeData, cb) {
console.log(handshakeData.query.lang);
cb(null, true);});

您也可以这样访问它:

io.sockets.on('connection', function(socket){
  console.log(socket.handshake.query.lang);
});

如果您不想将语言变量附加到 query ，则可以通过以下方式访问语言:

If you don't want to append language variable to query then you can access the language by this:

io.sockets.on('connection', function(socket){
  console.log(socket.handshake.headers['accept-language']);
});
