因为服务器Windows版本问题，无法使用curl，所以只能使用wget。
C:\Windows\System32\wget.exe
需求背景：
传入客户端参数，请求服务端。
将请求参数保存到文本文件中，命令行读取文本文件，然后分割字符串，循环发起http请求。
参数文本文件：
参数1,参数2,参数3,... ...命令行脚本文件：
@echo off & setlocal enabledelayedexpansion
chcp 65001 > NUL
set /p param_list=< "./参数文本文件.txt"
echo %param_list%
call :loop_block
goto :eof
:loop_block
for /f "tokens=1,* delims=," %%i in ("!param_list!") do (
echo %%i
set param=%%i
wget --header="User-Agents: Chrome" --header="Content-Type: application/json" --post-data='{"\"key"\":"\"!param!"\"}' http://localhost:8090/execute -q -O -
set param_list=%%j
goto loop_block
)
goto :eof测试执行：
服务端controller接收不到请求，控制台有以下信息：
2025-01-17 19:04:00.586 [http-nio-8090-exec-7] WARN o.s.w.s.m.support.DefaultHandlerExceptionResolver - Resolved [org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing: public java.util.Map<java.lang.String, java.lang.String> com.controller.MyController.execute(java.lang.String)]但是将参数改为英文字符，就可以正常接收到请求参数。
然后自定义一个Filter，看下请求到底是怎么回事，发现当参数为中文时会有以下报错：
2025-01-17 16:14:17.019 [http-nio-8090-exec-2] ERROR o.a.c.c.C.[.[localhost].[/].[dispatcherServlet] - Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception

然后无论是客户端还是服务端，尝试各种各样网罗来的解决方法，均无效😂
wget --local-encoding=utf-8 --remote-encoding=utf-8 --header="User-Agents: Chrome" --header="Accept-Charset: UTF-8" --header="Content-Type: text/plain;charset=UTF-8"最后实在没办法了，只好暂时使用native2ascii将参数文件转为unicode，问题可以解决
native2ascii -encoding UTF-8 旧参数文件.txt 新参数文件.txt如果有更好的、更直接的解决方法，希望大家随时交流😉。
加个计数器：
@echo off & setlocal enabledelayedexpansion
chcp 65001 > NUL
set /a counter=0
set /p param_list=< "./参数文本文件.txt"
echo %param_list%
call :loop_block
goto :eof
:loop_block
for /f "tokens=1,* delims=," %%i in ("!param_list!") do (
set /a counter+=1
echo 第!counter!个参数：%%i
set param=%%i
wget --local-encoding=utf-8 --remote-encoding=utf-8 --header="User-Agents: Chrome" --header="Accept-Charset: UTF-8" --header="Content-Type: text/plain;charset=UTF-8" --post-data='{"\"key"\":"\"!param!"\"}' http://localhost:8090/execute -q -O -
set param_list=%%j
goto loop_block
)
goto :eof因为set 变量长度有限制1023（中文按3个字符），可以考虑按行读取文件，同时再加一个耗时统计，脚本改进如下：
@echo off & setlocal enabledelayedexpansion
chcp 65001 > NUL
set param1=xxx
set /a counter=0
for /f "delims=" %%a in ('echo %time%') do set "startTime=%%a"
for /f "tokens=*" %%a in (./参数文件.txt) do (
set /a counter+=1
echo 第!counter!个参数：%%a
REM set key=%%a
wget --local-encoding=utf-8 --remote-encoding=utf-8 --header="User-Agents: Chrome" --header="Accept-Charset: UTF-8" --header="Content-Type: text/plain;charset=UTF-8" --post-data='{"\"key"\":"\"%%a"\"}' http://localhost:8090/execute -q -O -
)
for /f "delims=" %%a in ('echo %time%') do set "endTime=%%a"
for /f "tokens=1-4 delims=:." %%i in ("%startTime%") do (
set /a "startHour=%%i"
set /a "startMinute=%%j"
set /a "startSecond=%%k"
set /a "startMillisec=%%l"
)
for /f "tokens=1-4 delims=:." %%i in ("%endTime%") do (
set /a "endHour=%%i"
set /a "endMinute=%%j"
set /a "endSecond=%%k"
set /a "endMillisec=%%l"
)
set /a "startTimeSec=%startHour%*3600 + %startMinute%*60 + %startSecond%"
set /a "endTimeSec=%endHour%*3600 + %endMinute%*60 + %endSecond%"
set /a "diff=%endTimeSec% - %startTimeSec%"
:: 输出耗时结果
echo 耗时: %diff% 秒
endlocal
