Inno Setup-如何在线验证序列号 [英] Inno Setup - How to validate serial number online

问题描述

使用Inno Setup，将setup.exe分配给客户，根据合同，他只能使用2016年和2017年.但是在2018年1月1日，他应该不能继续使用相同的序列号2017年. >

如何使innosetup的setup.exe限制为自和至日期?

 [Setup]
#define SerialNumber "2017"
UserInfoPage=yes

[Code]
function CheckSerial(Serial: String): Boolean;
begin
  Result := Serial = '{#SerialNumber}';
end;
 

• setup.exe被执行
• 插入了许可证密钥
• 提交后，我要检查URL https://www.stackoverflow.com/query/license?id=2017
• 如果结果表明安装成功或否，则

解决方案

从以下代码开始: Inno设置-HTTP请求-获取www/web内容，您将获得类似的内容:

 [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 wither 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)类似于:

 <?

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";
}

考虑:

• 通过验证(例如使用代理服务器)并不难.
• 它也不会阻止用户从安装程序中提取文件并手动安装它们.
• 您可以仅在验证序列号之后才考虑在线下载实际文件.
• 或下载该应用程序正常运行所需的一些许可证文件.无论如何，如果要在许可证到期后强制应用程序停止运行，则仍然需要.

Using Inno Setup, setup.exe was given to a client, according to contract he is allowed only to use 2016 and 2017. But on 01-01-2018 he should not be able to continue with same serial 2017.

How to make the setup.exe by innosetup limited to from and to date?

[Setup]
#define SerialNumber "2017"
UserInfoPage=yes

[Code]
function CheckSerial(Serial: String): Boolean;
begin
  Result := Serial = '{#SerialNumber}';
end;

• setup.exe is executed
• license key is inserted
• after submit, i want to check URL https://www.stackoverflow.com/query/license?id=2017
• if the result is ok or nok based on that the installation continue

解决方案

Starting with a code from: Inno Setup - HTTP request - Get www/web content, you will get something like:

[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 wither 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;

A simple server-side validation PHP script (serial.php) would be like:

<?

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";
}

For consideration:

• This validation is not difficult to bypass, i.e. using a proxy server.
• It also does not prevent the user from extracting the files from the installer and installing them manually.
• You may consider instead an on-line download of the actual files only after validating the serial number.
• Or downloading some license file that the application will require for functioning. You need that anyway, if you want to enforce the application to stop working once the license expires.
