如何在使用Inno Setup的安装过程中检查端口是否可用? [英] How to check if a port is available during installation using Inno Setup?

问题描述

我正在尝试创建一个安装文件，以便在安装过程中它将检查一个端口(例如9000)，并让用户知道端口状态. 我是Inno Setup的新手，想知道这是否可行，我将如何检查呢?

I am trying to create a setup file, so that during installation it will check a port, say 9000, and let user know the port status. I am new to Inno Setup and wonder if this is possible, and how would I check for this?

推荐答案

您可以使用我的函数检查端口是否可用

you can use my function to check a port is available

请参阅:

  function CheckPortOccupied(Port:String):Boolean;
  var
    ResultCode: Integer;
  begin
   Exec(ExpandConstant('{cmd}'), '/C netstat -na | findstr'+' /C:":'+Port+' "', '',0,ewWaitUntilTerminated, ResultCode);
    if ResultCode  <> 1 then 
    begin
      Log('this port('+Port+') is occupied');
      Result := True; 
    end else
    begin
      Result := False;
    end;
  end;
