哪种形式的Nginx重写更有效？

Question

重构网站时，我在.htaccess中有一堆重定向。现在，我想为nginx重新创建它们。以下是否等效，哪种样式更有效？

# Style A
location / {
    location /foo/123/old {
        rewrite ^(.*) /bar/123/ permanent;
    }
    location /baz/456/old {
        rewrite ^(.*) /bar/456/ permanent;
    }
}

# Style B
location / {
    rewrite ^/foo/123/old\/?$ /bar/123/ permanent;
    rewrite ^/baz/456/old/\/?$ /bar/456/ permanent;
}

根据nginx自己的建议，您应该使用位置块和return指令
