rewrite

• https://nginx.org/en/docs/http/ngx_http_rewrite_module.html
• rewrite _regex_ _replacement_ [_flag]_;
• regex：
• replacement：
  • 尾部添加?表示把原URI的queryString带上
  • 如果是http://, https://, $scheme，则会停止且重定向
  • 这个就是重写后的路径，而不是说只是替换原来的
    • 比如 regex=a，路径=/a/b，replacement=c，结果是c，而不是/c/b
• flag
  • last：重写成功后，重新匹配location
  • break：重写成功后，不会重新匹配location，而是进行其他处理然后响应
  • redirect：直接重定向302
  • permant：直接重定向301
• 通常，这个会写在server context中
  • 如果在location中，则最大重写次数是10，超过就500（如果写在location中，regex不就和location的URI差不多嘛，就不太好）
  • 都可以写多个rewrite
