Inno设置-如何在线验证序列号

从以下代码开始: Inno Setup - HTTP request - Get www/web content

[Setup]
UserInfoPage=yes 

[Code]

// Presence of the CheckSerial event function displays the serial number box.
// But here we accept any non-empty serial.
// We will validate it only in the NextButtonClick,
// as the online validation can take long.
function CheckSerial(Serial: String): Boolean;
begin
  Result := (Serial <> '');
end;

function NextButtonClick(CurPageID: Integer): Boolean;
var
  WinHttpReq: Variant;
  Url: string;
begin
  Result := True;
  if CurPageID = wpUserInfo then
  begin
    WinHttpReq := CreateOleObject('WinHttp.WinHttpRequest.5.1');
    Url := 'https://www.example.com/serial.php?serial=' +
           WizardForm.UserInfoSerialEdit.Text;
    WinHttpReq.Open('GET', Url, False);
    WinHttpReq.Send('');
    // Depending on implementation of the server,
    // use either HTTP status code (.Status)
    // or contents of returned "page" (.ResponseText)
    // Here we use the HTTP status code:
    // 200 = serial is valid, anything else = serial is invalid,
    // and when invalid, we display .ResponseText
    Result := (WinHttpReq.Status = 200);
    if not Result then
      MsgBox(WinHttpReq.ResponseText, mbError, MB_OK);
  end;
end;

一个简单的服务器端验证PHP脚本( serial.php

<?

if (empty($_REQUEST["serial"]) || ($_REQUEST["serial"] != "2017"))
{
    header("HTTP/1.0 401 The serial number is not valid");
    // error message to be displayed in installer
    echo "The serial number is not valid";
}

• 这种验证不难绕过,即使用代理服务器。
• 它也不会阻止用户从安装程序中提取文件并手动安装。
• 或者下载应用程序运行所需的一些许可文件。无论如何,如果您想强制应用程序在许可证到期后停止工作,您需要这样做。
• 
  Read Inno Setup encryption key from Internet instead of password box
