我正在尝试使用 Ninx 重定向网址，但我正在努力使其正确：
example.com/{dynamic1}/foo/bar/{dynamic2} 到 example.com/{dynamic1}/bar/{dynamic2}
基本上我正在尝试删除网址的 /foo/ 部分。
我尝试了以下方法：
location ~* ^/(.*)/foo/bar/(.*)$ {
return 301 ^/$1/bar/$2?$args;
}
但这会引发错误 414 Request-URI Too Large 并且 url 最终被（为清楚起见缩短）：
dynamic1/cams/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/%5E/dynamic1/bar/dynamic2?
我做错了什么？
