nginx - 被请求文档的变量

Question

如果我有一个看起来像这样的位置块

location ~^ /foo/ { ... }

我收到一个对'/foo/bar'的请求，我怎么才能得到'bar'？

Answer 1

location ~ ^/foo/.*/?([^/]+)$
{
    set $doc $1;
    ...
}

The above assumes you want the very last part if the request, below the foo path.

If you just want the second part:

location ~ ^/foo/(.*)$
{
    set $doc $1;
}
