found .net URLEncode 小文字の問題

url escape & (6)




私はUrlEncoded形式でデータを送信する必要があるゲートウェイのデータ転送に取り組んでいます。 しかし、.netのUrlEncodeは小文字のタグを作成し、転送を中断します(Javaは大文字を作成します)。



.net out:





Answer #1


Regex.Replace( encodedString, @"%[a-f\d]{2}", m => m.Value.ToUpper() )


Answer #2


これで、文字列をループし、%記号の後の2文字だけを大文字にする必要があります。 エンコードされた文字を適切な形式にマッサージしながら、base64データをそのまま維持します。

public static string UpperCaseUrlEncode(string s)
  char[] temp = HttpUtility.UrlEncode(s).ToCharArray();
  for (int i = 0; i < temp.Length - 2; i++)
    if (temp[i] == '%')
      temp[i + 1] = char.ToUpper(temp[i + 1]);
      temp[i + 2] = char.ToUpper(temp[i + 2]);
  return new string(temp);

Answer #4


static string UrlEncodeUpperCase(string value) {
    value = HttpUtility.UrlEncode(value);
    return Regex.Replace(value, "(%[0-9a-f][0-9a-f])", c => c.Value.ToUpper());

var value = "SomeWords 123 #=/ äöü";

var encodedValue = HttpUtility.UrlEncode(value);
// SomeWords+123+%23%3d%2f+%c3%a4%c3%b6%c3%bc

var encodedValueUpperCase = UrlEncodeUpperCase(value);
// now the hex chars after % are uppercase:
// SomeWords+123+%23%3D%2F+%C3%A4%C3%B6%C3%BC

UrlEncode (.NET 2.0 / 3.5用)の公開OAuth.OAuthBaseバージョンの私のVB.NET変換は次のとおりです。

' MEH: Made this ReadOnly because the range of unreserved characters is specified in the OAuth spec. Inheritors ought not change it.
Protected Shared ReadOnly unreservedChars As String = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-_.~"
' MEH: Added. These are the other characters HttpUtility.UrlEncode does not convert to percent encoding itself.
Protected Shared ReadOnly reservedChars As String = " !'()*" ' If this moves to .NET 4+ ' can be removed.

''' <summary>
''' This is a different Url Encode implementation since the default .NET one outputs the percent encoding in lower case.
''' While this is not a problem with the percent encoding spec, it is used in upper case throughout OAuth.
''' Also the OAuth spec explicitly requires some characters to be unencoded.
''' </summary>
''' <param name="Value">The value to Url encode</param>
''' <returns>Returns a Url encoded string</returns>

'''   140313 MEH Fixed to correctly cater for any characters between %80 and %ff, and the O(n^2) IndexOf call.
