express.js中的多语言路由? [英] Multi-language routes in express.js?

问题描述

我想知道是否有一个关于在express.js中实现多语言路由的最佳实践示例.我想使用accept-language标头获取浏览器语言，然后自动重定向到相应的语言路线，例如

I'm wondering if there is a best practise example on how to implement multi-lanuage routes in express.js. i want to use the accept-language header to get the browser language and then redirect automatically to the corresponding language route like

www.foo.bar/de/startseite或 www.foo.bar/en/home

对此有何建议?

推荐答案

我完成了以下操作: 安装i18n-node modul并在express js中注册.这是代码.

i have done the following: install i18n-node modul and register in the express js. here is code.

var express = require('express')
  , routes = require('./routes')
  , http = require('http')
  , i18n = require("i18n");

  var app = express();

i18n.configure({
    // setup some locales - other locales default to en silently
    locales:['de', 'en'],
    // disable locale file updates
    updateFiles: false
});

app.configure(function(){
  ...
  app.use(i18n.init);
  ...
});
// register helpers for use in templates
app.locals({
  __i: i18n.__,
  __n: i18n.__n
});

在此之后设置以下内容以获取所有请求

after this set the following to get all request

// invoked before each action
app.all('*', function(req, res, next) {
    // set locale
    var rxLocal = /^\/(de|en)/i;
    if(rxLocal.test(req.url)){
        var arr = rxLocal.exec(req.url);
        var local=arr[1];
        i18n.setLocale(local);
    } else {
        i18n.setLocale('de');
    }
    // add extra logic
    next();
});

app.get(/\/(de|en)\/login/i, routes.login);

也许有帮助.
