从命令行设置Inno Setup自定义页面字段的值 [英] Setting value of Inno Setup custom page field from command-line

问题描述

我已经配置了以下脚本，作为安装向导的一部分，要求用户提供IP地址，该地址将写入到配置文件中，应用程序将参考该文件以了解在何处进行通信.我也想提供机会在命令行中将此IP地址指定为参数，以便可以自动进行部署并以静默方式执行.

从我的研究来看，似乎可以添加一个命令行参数，但是我正努力了解如何在Inno设置中准确设置此参数，然后如何使该参数成为可选参数以允许在命令行上指定它.命令行或通过安装向导.

例如app1.exe /ipaddress 192.168.0.1

之类的东西

很抱歉，如果这是一个简单的过程，我是Inno Setup的新手，所以我们将感谢您的帮助.

任何人都可以提供任何帮助来帮助我进行此设置吗?

 [Code]

var
  PrimaryServerPage: TInputQueryWizardPage;

function FileReplaceString(ReplaceString: string):boolean;
var
  MyFile : TStrings;
  MyText : string;
begin
  Log('Replacing in file');
  MyFile := TStringList.Create;

  try
    Result := true;

    try
      MyFile.LoadFromFile(ExpandConstant('{app}' + '\providers\win\config.conf'));
      Log('File loaded');
      MyText := MyFile.Text;

      { Only save if text has been changed. }
      if StringChangeEx(MyText, 'REPLACE_WITH_CUSTOMER_IP', ReplaceString, True) > 0 then
      begin;
        Log('IP address inserted');
        MyFile.Text := MyText;
        MyFile.SaveToFile(ExpandConstant('{app}' + '\providers\win\config.conf'));
        Log('File saved');
      end;
    except
      Result := false;
    end;
  finally
    MyFile.Free;
  end;

  Result := True;
end;

procedure InitializeWizard;
begin
  PrimaryServerPage :=
    CreateInputQueryPage(
      wpWelcome, 'Application Server Details', 'Where is installed?',
      'Please specify the IP address or hostname of your ' +
        'Primary Application Server, then click Next.');
  PrimaryServerPage.Add('Primary Application Server IP/Hostname:', False);
end;   

procedure ReplaceIPAddress;
begin
  FileReplaceString(PrimaryServerPage.Values[0]);
end;
 

解决方案

读取命令行参数的一种简单方法是解析 ExpandConstant函数:

 procedure InitializeWizard;
begin
  PrimaryServerPage :=
    CreateInputQueryPage(
      wpWelcome, 'Application Server Details', 'Where is installed?',
      'Please specify the IP address or hostname of your ' +
        'Primary Application Server, then click Next.');
  PrimaryServerPage.Add('Primary Application Server IP/Hostname:', False);
  PrimaryServerPage.Values[0] := ExpandConstant('{param:ipaddress}');
end;   
 

在命令行上，使用以下语法提供值:

mysetup.exe /ipaddress=192.0.2.0

如果要自动运行安装程序，请在静默模式下跳过页面.对于该查询， WizardSilent函数 /jrsoftware.org/ishelp/index.php?topic=scriptevents&anchor=ShouldSkipPage"rel =" nofollow noreferrer> ShouldSkipPage事件函数:

 function ShouldSkipPage(PageID: Integer): Boolean;
begin
  Result := False;

  if PageID = PrimaryServerPage.ID then
  begin
    Result := WizardSilent;
  end;
end;
 

现在，您可以使用以下命令行语法来提供值并避免出现任何提示:

mysetup.exe /silent /ipaddress=192.0.2.0

I have configured the below script to ask the user for an IP address as part of the install wizard, this address gets written to a config file which the application will reference to know where to communicate with. I would like to offer the opportunity to specify this IP address as a parameter in the command line as well so that deployment can be automated and performed silently.

From my research, it seems to be possible to add a command line parameter but I am struggling to understand exactly how to set this up within my Inno setup and then how I can make this optional to allow it to be specified on the command line or through the install wizard.

For example something like app1.exe /ipaddress 192.168.0.1

Apologies if this is an easy process, I am new to Inno Setup so any help would be appreciated.

Can anyone offer any assistance to help me get this setup?

[Code]

var
  PrimaryServerPage: TInputQueryWizardPage;

function FileReplaceString(ReplaceString: string):boolean;
var
  MyFile : TStrings;
  MyText : string;
begin
  Log('Replacing in file');
  MyFile := TStringList.Create;

  try
    Result := true;

    try
      MyFile.LoadFromFile(ExpandConstant('{app}' + '\providers\win\config.conf'));
      Log('File loaded');
      MyText := MyFile.Text;

      { Only save if text has been changed. }
      if StringChangeEx(MyText, 'REPLACE_WITH_CUSTOMER_IP', ReplaceString, True) > 0 then
      begin;
        Log('IP address inserted');
        MyFile.Text := MyText;
        MyFile.SaveToFile(ExpandConstant('{app}' + '\providers\win\config.conf'));
        Log('File saved');
      end;
    except
      Result := false;
    end;
  finally
    MyFile.Free;
  end;

  Result := True;
end;

procedure InitializeWizard;
begin
  PrimaryServerPage :=
    CreateInputQueryPage(
      wpWelcome, 'Application Server Details', 'Where is installed?',
      'Please specify the IP address or hostname of your ' +
        'Primary Application Server, then click Next.');
  PrimaryServerPage.Add('Primary Application Server IP/Hostname:', False);
end;   

procedure ReplaceIPAddress;
begin
  FileReplaceString(PrimaryServerPage.Values[0]);
end;

解决方案

One easy way to read command-line parameter is to resolve {param:} pseudo-constant using ExpandConstant function:

procedure InitializeWizard;
begin
  PrimaryServerPage :=
    CreateInputQueryPage(
      wpWelcome, 'Application Server Details', 'Where is installed?',
      'Please specify the IP address or hostname of your ' +
        'Primary Application Server, then click Next.');
  PrimaryServerPage.Add('Primary Application Server IP/Hostname:', False);
  PrimaryServerPage.Values[0] := ExpandConstant('{param:ipaddress}');
end;   

On command-line, use this syntax to provide the value:

mysetup.exe /ipaddress=192.0.2.0

Shall you want to run the installer automatically, make the page be skipped in the silent mode. For that query WizardSilent function in ShouldSkipPage event function:

function ShouldSkipPage(PageID: Integer): Boolean;
begin
  Result := False;

  if PageID = PrimaryServerPage.ID then
  begin
    Result := WizardSilent;
  end;
end;

Now you can use this command-line syntax to provide the value and avoid any prompts:

mysetup.exe /silent /ipaddress=192.0.2.0
