如何在Laravel 5中检测语言偏好 [英] How to detect language preference in Laravel 5

问题描述

我想通过获取浏览器推荐的语言来检测客户端语言.

I want to detect my client language by getting the browser recommended language.

例如，如果您在日本打开浏览器，则会向我提供当前打开的用户的国家代码或国家名称，例如"en-jp"或"japan".

For Example, if you open the browser in Japan it will give me country code or country name current user opened like "en-jp" or "japan".

我尝试使用此代码，但它似乎显示了我先前选择的语言，默认情况下为英语.

I try this code but it seems to display the language that I previously selected and by default it's English.

我设置了一个中间件，并且需要排除api部分，因为我有一些路由器ping该地址，并且路由器浏览器没有语言信息，这会阻塞系统.

I set a Middleware and I need to exclude the api part because I have some routers pinging this address and router browser does not have language information which brick the system.

class BeforeMiddleware
{

/**
 * Handle an incoming request.
 *
 * @param  \Illuminate\Http\Request $request
 * @param  \Closure $next
 * @return mixed
 */

protected $except_urls = [
    'api/*'
];

public function handle($request, Closure $next)
{
    $langArr = array("en", "fr");
    if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {
        $languages = explode(',', $_SERVER['HTTP_ACCEPT_LANGUAGE']);
    } else {
        $languages[0] = "en";
    }
    if (Session::has('locale')) {
        App::setLocale(Session::get('locale'));
    } else {
        if (in_array($languages[0], $langArr))
            App::setLocale($languages[0]);
    }
    return $next($request);
}


} /* end class */

感谢您的帮助.

推荐答案

要简单地从标题中获取语言环境，可以从请求中获取http-accept-language值.这可以通过外观访问，也可以在中间件中使用request变量:

To simply get the locale from the header, you can grab the http-accept-language value from the request. This is accessible via a facade or you can use the request variable in your middleware:

Request::server('HTTP_ACCEPT_LANGUAGE')

// OR

$request->server('HTTP_ACCEPT_LANGUAGE');

这将返回一个类似于以下内容的字符串:en-GB,en;q=0.8.然后，您可以解析它(也许使用explode()?)并从那里获取语言.

This returns a string which looks like this: en-GB,en;q=0.8. You can then parse it (perhaps using explode()?) and grab the language from there.

但是，这种事情有时会变得复杂.如果您需要做更高级的事情，有一个软件包可以为您完成所有这些工作:

However, this sort of thing can sometimes get complicated. If you need to do something more advanced, there's a package which can do all of this for you:
