什么是内容语言和接受语言？ [英] What are Content-Language and Accept-Language?

问题描述

我看过 Content-Language 的HTTP标头和 Accept-Language ，有人可以解释一下这些是什么为了和它们之间的区别？我有一个多语言网站，想知道我是否应该由用户设置网站当前所选语言。

I have seen the HTTP headers of Content-Language and Accept-Language, could someone explain what these are for and the difference between them? I have a multilingual site and wondering should I be setting both to the sites current selected language, by the user.

推荐答案

Content-Language 来自服务器，让客户知道所请求页面上的语言。 Accept-Language 来自客户端，让服务器知道用户的首选语言。可以有多种语言，每种语言都有可选的权重或质量值。例如：

Content-Language is from the server, and lets the client know what language(s) are present on the requested page. Accept-Language is from the client, and lets the server know the user's preferred language(s). There can be multiple languages, each with an optional weight or 'quality' value. For example:

Accept-Language: da, en-gb;q=0.8, en;q=0.7

（默认权重为1，因此相当于 da; q = 1，en -gb; q = 0.8，en; q = 0.7 ）。

(The default weight is 1, so this is equivalent to da;q=1, en-gb;q=0.8, en;q=0.7).

您将需要解析值和权重才能看到如果有适当的翻译，并向用户提供最高首选语言权重的翻译。

You're going to have to parse the values and weights to see if an appropriate translation is available, and provide the user the translation in the highest preferred language weight.

建议您为用户提供替代方案，例如cookie集值，强制为您的网站使用某种语言。这是因为某些用户可能希望以某种语言查看您的网站，而不会更改其语言接受偏好。

It is recommended you give the users an alternative, such as a cookie set value, to force a certain language for your site. This is because some users may want to see your site in a certain language, without changing their language acceptance preferences.
