HTTPプロトコルでは、ファイルパスにエンコードされたスペースが必要ですか？ HTTPプロトコルで

、HTTPプロトコルでは、ファイルパスにエンコードされたスペースが必要ですか？ HTTPプロトコルで

ファイル名にスペースがある場合requsestの最初の行は、例えば

GET /img/my house.jpg HTTP/1.1

私の質問は、ありさのように、プロトコルは、何らかの方法でエンコードされることを必要としません？（プロトコルが明確でない場合や、実際の状況は何ですか？）

これはすでにここに尋ねた、まさに次のとおりです。http：// stackoverflow.com/questions/4665124/space-in-url-did-browser-got-smarter-or-server/4665137#4665137 – Brad

いいえ、正確な複製はありません。 – jgauffin

これを％20としてエンコードする必要があります。ここにその理由があります。まず、RFC 2616 5.1.2 ...

リクエストライン=メソッドのSPのRequest-URI SP HTTP-バージョンCRLF

と...

のRequest-URI = "*" |絶対値| abs_path |権限

今

のはRFC 1808にオーバーホップ、あなたはURLとパスの仕様にスペースがないことに注意しましょうしましょう...

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" |

       "S" | "T" | "U" | "V" | "W" | "X" | "Y" | "Z" 

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

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