nginx 使用 OR 设置为地图的正则表达式
nginx using OR set at regex for the map
我正在尝试为我的网站编写地图并且效果很好:
map $request_uri $redirect_uri {
/en/oldname /en/newname;
/de/oldname /de/newname;
/fr/oldname /fr/newname;
}
直到我尝试实现一些正则表达式,如下所示:
map $request_uri $redirect_uri {
/(?<lang>(en|de|fr))/oldname /$lang/newname;
}
上面的地图不工作,由于缺乏调试知识 - 我不知道为什么。即使是基本的正则表达式(不使用命名捕获)也不适合我:
map $request_uri $redirect_uri {
/(en|de|fr)/oldname /en/newname;
}
nginx 1.10.3
请帮我找出我做错了什么?
Mike,你应该用“~”符号表示正则表达式。
A regular expression should either start from the “~” symbol for a case-sensitive matching, or from the “~*” symbols (1.0.4) for case-insensitive matching. A regular expression can contain named and positional captures that can later be used in other directives along with the resulting variable.
正确的配置应该是:
map $request_uri $redirect_uri {
~/(?<lang>(en|de|fr))/oldname /$lang/newname;
}
祝你好运!

这是我的测试用例:

/de/newname
yxr nginx # curl localhost/fr/oldname
/fr/newname
yxr nginx # curl localhost/cn/oldname
yxr nginx #

正如@Mike 指出的那样,这至少需要 nginx/1.11.0
。
关于mononoke的回答。您不需要在模式匹配中使用额外的一组括号,这可能会给某些 pcre 引擎带来一些意想不到的结果,因为您在技术上是在 lang 组中添加另一个组。
~/(?<lang>en|de|fr)/oldname /$lang/newname;
map $http_user_agent $loggable {
"~kube-probe" 0;
default 1;
}
