nginx下二级目录怎么写重定向？

Question

有这样形式的URLwww.example.com/abc/1.html
www.example.com/bdc/3.html
www.example.com/utf/2.html
若干个，希望重定向到对应的
test.example.com/abc/1.html
test.example.com/bdc/3.html
test.example.com/utf/2.html

abc,bdc,utf这样的目录是已知固定数量的那几个。

不用root 映射，直接用nginx的rewrite 应该如何写？
这个是我的写法：

location ^~/(abc|bdc|utf)/(*.html) {

   rewrite ^~/*/(*.html)  https://test.example.com/$!  permanent;

}

不对呢～

Answer 1

location ^~/(abc|bdc|utf)/(*.html) {

   rewrite ^~/*/(*.html)  https://test.example.com/$request_uri  permanent;

}

Answer 2

试试这个:

location ^~/(abc|bdc|utf)/(*.html) {

   rewrite ^(.*) https://test.example.com/$1  permanent;

}
