用用户在 Inno Setup 中输入的输入替换已安装文本文件中的占位符 [英] Replace placeholder in an installed text file with input entered by user in Inno Setup

问题描述

作为 Inno Setup 内置安装程序的一部分，我想将用户输入安装程序的文本字段输出到文本文件中.

As part of an Inno Setup built installer, I want to output the text field that the user enters into the installer to a text file.

到目前为止，我有以下内容:

So far I have the below:

[Code]
var
  PrimaryServerPage: TInputQueryWizardPage;
  PrimaryAddress: String;

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

  PrimaryAddress := PrimaryServerPage.Values[0];

  SaveStringToFile('c:filename.txt', PrimaryAddress, True);
end;

但是，当我运行安装程序并输入该字段时，它不会输出到文本文件.

However, when I run the installer and enter the field it does not output to the text file.

如果我将 PrimaryServerPage.Values[0] 替换为一个数字，则会成功输出到文本文件.

If I replace PrimaryServerPage.Values[0] with a number this is successfully output to the text file.

任何人都可以帮助或提供有关我可能出错的地方的建议吗?

Can anyone help or offer suggestions on where I might be going wrong?

此外，在此之后，我实际上想将此值输出到现有文本文件的中间，这可能吗?例如，这是我希望将其插入的配置文件.要添加到 ENTER VALUE HERE 中的值！这可以作为安装的最后一步添加吗?安装完成后配置文件不存在?

Also, following this I actually want to output this value into the middle of an existing text file, is this possible? For example here is the config file I wish to insert it into. Value to be added into ENTER VALUE HERE! Can this be added as a last step of the installation? The config file will not exist until after the install is complete?

ApplicationServer=ENTER VALUE HERE!

工作正在进行中，在我查看替换之前，一直在让文本文件输出正常工作(我想我可能误解了关于此的帖子)，尽管任何有关这方面的指导都会很棒，因为我确信我对此缺乏经验Inno 也会在那里抓住我.

Work in progress, getting stuck with getting the text file output working (I think I may be misunderstanding the post on this) before I look at the replace although any guidance around that would be great as I'm sure my inexperience with Inno is going to catch me out there too.

[Code]
var
  PrimaryServerPage: TInputQueryWizardPage;
  PrimaryAddress: String;

   
function NextButtonClick(CurPageID: Integer): Boolean;
begin
  if(CurPageID = wpWelcome) then
  begin

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

  PrimaryAddress := PrimaryServerPage.Values[0];

  SaveStringToFile('c:filename.txt', PrimaryAddress, True);
  end;
 
  Result :=True;
end;

推荐答案

结合这两个问题的答案:

Combining answers to these two questions:

• 使用 Inno Setup 替换文件中的文本(FileReplaceString 函数)
• Inno Setup Compiler:如何修改文件内容(使用 CurStepChanged(ssPostInstall) 事件函数)

• Replace a text in a file with Inno Setup (FileReplaceString function)
• Inno Setup Compiler: How to modify file content (use of CurStepChanged(ssPostInstall) event function)

你会得到一个类似的代码:

you will get a code like:

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}' + '	hefile.txt'));
      Log('File loaded');
      MyText := MyFile.Text;

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

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

procedure CurStepChanged(CurStep: TSetupStep);
begin
  if CurStep = ssPostInstall then
  begin
    Log('File installed, replacing IP address');
    FileReplaceString(PrimaryServerPage.Values[0]);
  end;
end;
