Question

@echo off
cls
Color 0A

if exist index.html del index.html
wget -q --show-progress http://cemu.info/
setlocal disableDelayedExpansion

for /f delims^=^ eol^= %%A in ('findstr /ri /c:"http://cemu.info/releases/" /c:"http://cemu.info/releases/" index.html') do (
  set "ln=%%A"
  setlocal enableDelayedExpansion
  set "ln=!ln:*:=!"
  if /i "!ln:~0,5!" equ "http://cemu.info/releases/" (set "ln=!ln:~5!") else set "ln=!ln:* "http://cemu.info/releases/ =!"
  for /f %%B in ("!ln!") do if "%%B" neq "" echo "http:%%B" > cemu_ver.txt
  endlocal
)
if exist index.html del index.html
notepad.exe cemu_ver.txt

它有效但不是http://cemu.info/releases/cemu_1.8.1.zip

打印＆＃34; http://cemu.info/releases/cemu_1.8.1.zip＆＃34;＆＃34;

（单个＆＃34;开头是双＃34;＆＃34;最后）

也http：被删除，这让我很困扰

无论如何要解决这个问题？

Answer 1

我找到了一个解决方法：

@echo off
cls
Color 0A

if exist index.html del index.html
.\bin\wget -q --show-progress http://cemu.info/
setlocal disableDelayedExpansion

for /f delims^=^ eol^= %%A in ('findstr /ri /c:"http://cemu.info/releases/" /c:"http://cemu.info/releases/" index.html') do (
  set "ln=%%A"
  setlocal enableDelayedExpansion
  set "ln=!ln:*:=!"
  if /i "!ln:~0,5!" equ "http://cemu.info/releases/" (set "ln=!ln:~5!") else set "ln=!ln:* "http://cemu.info/releases/ =!"
  for /f %%B in ("!ln!") do if "%%B" neq "" echo http:%%B > cemu_ver.txt
  endlocal
)
if exist index.html call :add-quote
goto skip-quote

:add-quote
set /p cemu_ver=<cemu_ver.txt
echo "%cemu_ver% > cemu_ver.txt
del index.html
(goto) 2>NUL

:skip-quote
notepad.exe cemu_ver.txt

Answer 2

为什么这么复杂，使用"作为分隔符并获取tokens=2

@echo off
cls
Color 0A
if exist index.html del index.html
wget -q http://cemu.info/
for /f tokens^=2delims^=^" %%A in (
  'findstr /i /c:"http://cemu.info/releases/" /c:"http://cemu.info/releases/" index.html'
) Do > cemu_ver.txt Echo:"%%A"

批量文件下载并自动搜索更新。有用。但它打印额外的符号，并不打印开头
