Delphi：如何将互联网上的文本文件加载成字符串？ [英] Delphi: How to load a text file on the internet into a string?

问题描述

在我的程序中，我有一个功能来检查程序的当前版本，它是从url获得的：www.tablemaster.webs.com/versioninfo.txt

如您所见，URL只是纯文本。我需要将这个文本从URL中加载到我的程序中的字符串中，我该怎么做？我搜索过，但没有发现任何东西。

PS：我需要最简单的代码。

感谢提前：）

解决方案

我将使用Indy的 TIdHTTP ，这样最简单的GET重载：

 使用
 IdHTTP; 
 
 procedure TForm1.Button1Click（Sender：TObject）; 
 var 
 S：string; 
 IdHTTP：TIdHTTP; 
 begin 
 IdHTTP：= TIdHTTP.Create（nil）; 
 try 
 S：= IdHTTP.Get（'http://www.tablemaster.webs.com/versioninfo.txt'）; 
 ShowMessage（S）; 
 finally 
 IdHTTP.Free; 
结束
结束
  

On my program I have a function that checks for the current version of the program, which it gets from the url: www.tablemaster.webs.com/versioninfo.txt

As you can see, at the URL is just plain text. I need to load this text from the URL into a string on my program, how will I go about doing this? I've searched around but found nothing..

PS: I need the simplest code possible..

Thanks in advance :)

解决方案

I would use Indy's TIdHTTP with it's easiest GET overload this way:

uses
  IdHTTP;

procedure TForm1.Button1Click(Sender: TObject);
var
  S: string;
  IdHTTP: TIdHTTP;
begin
  IdHTTP := TIdHTTP.Create(nil);
  try
    S := IdHTTP.Get('http://www.tablemaster.webs.com/versioninfo.txt');
    ShowMessage(S);
  finally
    IdHTTP.Free;
  end;
end;
