바니시로 후행 슬래시를 추가하는 방법은 무엇입니까?

Question

바니시가있는 모든 URL에 후행 슬래시를 추가하고 싶습니다 (301 리디렉션을 통해).

그러나 나는 어디에서나 온라인에서 아무 것도 찾을 수 없다는 것에 놀랐다.

이것은 내가 얻은 것 중 가장 가까운 것이지만, 쿼리 문자열이나 기타를 고려하지 않았기 때문에 분명히 깨졌습니다. 그 안에.

if (req.url !~ "/$") { 
    return (synth (751, "")); 
} 

... 내가

example.com/xyz?query=string을 설명 할

sub vcl_synth { 
    if (resp.status == 750) { 
    set resp.status = 301; 
    set resp.http.Location = "http://www.example.com" + req.url; 
    return(deliver); 
    } 
} 

테스트 케이스 ->www.example.com/xyz/?query=string (추가, WWW를 추가 /)

example.com/api/latest.json ->www.example.com/api/latest.json (WWW를 추가 , 추가하지 마시오 /)

여기에 당신은 내가이없는 니스 (4)로 번역 할 수 니스 3에 대한 해결책은 니스 4 편리하게 자신 :

sub vcl_recv { 
    if (req.http.Host !~ "^www\." || (
      req.url !~ {"(?x) 
       (?:/$)   # last character isn't a slash 
       |    # or 
       (?:/\?)  # query string isn't immediately preceded by a slash 
      "} && 
      req.url ~ {"(?x) 
       (?:/[^./]+$) # last path segment doesn't contain a . no query string 
       |    # or 
       (?:/[^.?]+\?) # last path segment doesn't contain a . with a query string 
      "}) 
    ) { 
     error 720; 
    } 
} 

sub vcl_error { 
    if (obj.status == 720) { 
     set obj.status = 301; 

     set obj.http.Location = "http://"; 
     set obj.http.Host = req.http.Host; 
     if (obj.http.Host !~ "^www\.") { 
      // for www. prefix 
      set obj.http.Host = "www." + obj.http.Host; 
     } 
     set obj.http.Location = obj.http.Location + obj.http.Host; 

     if (req.url ~ "(?:/[^./]+$)|(?:/[^.?]+\?)") { 
      // no . in last path segment before optional query string 
      if (req.url !~ "/$" && req.url !~ "\?") { 
       // no trailing slash and no query string 
       set obj.http.Location = obj.http.Location + req.url + "/"; 
      } else if (req.url ~ "[^/]\?") { 
       // no trailing slash and with query string, preserve it 
       set obj.http.Location = obj.http.Location + 
        regsub(req.url, "([^?]+)\?.*", "\1") + 
        "/" + 
        regsub(req.url, "[^?]+(\?.*)", "\1"); 
      } else if (obj.http.Host != req.http.Host) { 
       // trailing slash rule met, handle missing www. scenario 
       set obj.http.Location = obj.http.Location + req.url; 
      } 
     } else if (obj.http.Host != req.http.Host) { 
      // last path segment contains a . so handle missing www. scenario 
      set obj.http.Location = obj.http.Location + req.url; 
     } 
     set obj.response = "Moved Permanently"; 
    } 
}
