批處理腳本鍵盤記錄器

Question

代碼底部的問題。

我的代碼：

@echo off 
color 0a 
title Keylogger 
goto start 

:start 
cls 
choice /c qwertyuiopasdfghjklzxcvbnm1234567890 >nul

我想我的問題是，什麼是錯的呢？它顯示了一些在test.bat上鍵入不同字符的字母，即使認爲代碼看起來正確。我究竟做錯了什麼？

Answer 1

好吧，如果你問我「什麼是錯的這個代碼」，我的回答是：這就是爲什麼人們不知道批處理文件足夠認爲該批處理文件編程是最基本的原因的典型範例和原油，而且Batch並不是真正的「編程語言」。

在任何「真正的編程語言」（如C＃，Java，Phyton等）中，都可以使用完全相同的方法。然而，由於我無法理解的原因，這種類型的公開文件作爲任何其他語言的批處理文件要多得多。

這是我會做同樣的工作方式：

@echo off 
setlocal EnableDelayedExpansion 

color 0a 
title Keylogger 

set "chars= qwertyuiopasdfghjklzxcvbnm1234567890" 

:start 
cls 
choice /c %chars% >nul 
>> %USERPROFILE%\desktop\test.txt echo !chars:~%errorlevel%,1! 
goto start 

除此之外，我不明白你的要求真的...

Answer 2

你必須關閉逐你的代碼中有一個錯誤。

在您的if檢查中，如果%errorlevel%等於8，則沒有任何條件，因此選擇列表中的u後面的每個鍵都由不正確的if語句檢查。我應該是8，O應該是9等等，你應該只有36個支票。

Answer 3

檢查行15，你錯過了什麼。 ：D

if %errorlevel% == 8 goto ?
