Question

HTTP协议中的

，

第一行要求就像例如

GET /img/my house.jpg HTTP/1.1

我的问题是，如果文件名有空格，协议是否要求以某种方式对其进行编码？（如果协议不清楚，实际情况是什么？）

Answer 1

是的，它需要进行URL编码，即

GET /img/my%20house.jpg HTTP/1.1

其中%20表示相关字符的十六进制值

P.S。你没有already ask吗？

Answer 2

你必须将它编码为％20，这就是原因。首先，RFC 2616第5.1.2节......

Request-Line =方法SP Request-URI SP HTTP-Version CRLF

和...

Request-URI =“*”| absoluteURI | abs_path |权威

现在让我们跳到RFC 1808，你会注意到URL和路径规范中缺少空格......

   URL         = ( absoluteURL | relativeURL ) [ "#" fragment ]

   absoluteURL = generic-RL | ( scheme ":" *( uchar | reserved ) )

   generic-RL  = scheme ":" relativeURL

   relativeURL = net_path | abs_path | rel_path

   net_path    = "//" net_loc [ abs_path ]    
   abs_path    = "/"  rel_path   
   rel_path    = [ path ] [ ";" params ] [ "?" query ]

   path        = fsegment *( "/" segment )    
   fsegment    = 1*pchar    
   segment     =  *pchar

   params      = param *( ";" param )  
   param       = *( pchar | "/" )

   scheme      = 1*( alpha | digit | "+" | "-" | "." )    
   net_loc     =  *( pchar | ";" | "?" )    
   query       =  *( uchar | reserved )    
   fragment    =  *( uchar | reserved )

   pchar       = uchar | ":" | "@" | "&" | "="    
   uchar       = unreserved | escape    
   unreserved  = alpha | digit | safe | extra

   escape      = "%" hex hex    
   hex         = digit | "A" | "B" | "C" | "D" | "E" | "F" |
                         "a" | "b" | "c" | "d" | "e" | "f"

   alpha       = lowalpha | hialpha    
   lowalpha    = "a" | "b" | "c" | "d" | "e" | "f" | "g" | "h" | "i" |
                 "j" | "k" | "l" | "m" | "n" | "o" | "p" | "q" | "r" |
                 "s" | "t" | "u" | "v" | "w" | "x" | "y" | "z"    
   hialpha     = "A" | "B" | "C" | "D" | "E" | "F" | "G" | "H" | "I" |
                 "J" | "K" | "L" | "M" | "N" | "O" | "P" | "Q" | "R" |
                 "S" | "T" | "U" | "V" | "W" | "X" | "Y" | "Z"

   digit       = "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" |
                 "8" | "9"

   safe        = "$" | "-" | "_" | "." | "+"    
   extra       = "!" | "*" | "'" | "(" | ")" | ","    
   national    = "{" | "}" | "|" | "\" | "^" | "~" | "[" | "]" | "`"    
   reserved    = ";" | "/" | "?" | ":" | "@" | "&" | "="    
   punctuation = "<" | ">" | "#" | "%" | <">

Answer 3

是

规范定义了请求行，如下所示：
Request-Line = Method SP Request-URI SP HTTP-Version CRLF
请注意，空格是请求行中的分隔符。

Answer 4

是。 %20。有关详细信息，请参阅RFC 1738。

您应该记住，HTTP URI的路径组件不是“文件路径”。它只是资源的分层路径，它不需要与服务器上的任何文件相对应。

Answer 5

空间需要编码为％20，编码规则记录在RFC3986中。你通常最好让图书馆负责网址编码。

HTTP协议是否需要在文件路径中编码空间？
