url编码与解码工具附代码

url编码与解码工具附代码，代码很简单，做sql注入分析时经常用到，但一时又找不到，就写了一个

代码部分：

unit Unit1;

interface

uses

Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,

Dialogs, StdCtrls, HTTPApp;

type

TForm1 = class(TForm)

Button1: TButton;

Memo1: TMemo;

Memo2: TMemo;

Button2: TButton;

procedure Button1Click(Sender: TObject);

procedure Button2Click(Sender: TObject);

private

{ Private declarations }

function URLEncode(const msg : String) : String;

function GetMemoText(memo:TMemo):string;

public

{ Public declarations }

end;

var

Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);

var

i: Integer;

ss: string;

begin

ss := GetMemoText(Memo1);

Memo1.Text :=ss;

Memo2.Clear;

for i := 1 to Length(ss) do

begin

Memo2.Text := Memo2.Text + '%' + IntToHex(Ord(ss), 2);

end;

end;

function TForm1.URLEncode(const msg: String): String;

var

I : Integer;

begin

Result := '';

for I := 1 to Length(msg) do begin

if msg[I] = ' ' then

Result := Result + '+'

else if msg[I] in ['a'..'z', 'A'..'Z', '0'..'9'] then

Result := Result + msg[I]

else

Result := Result + '%' + IntToHex(ord(msg[I]), 2);

end;

end;

procedure TForm1.Button2Click(Sender: TObject);

var ss:string;

begin

Memo2.Clear;

ss :=GetMemoText(Memo1);

Memo1.Text :=ss;

Memo2.Text :=HTTPDecode(trim(ss));

end;

function TForm1.GetMemoText(memo: TMemo): string;

var i:integer;

begin

for i:=0 to memo.Lines.Count-1 do

begin

Result :=Result + trim(memo.Lines);

end;

end;

end.
