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.
