如何使用 cURL 在 Windows 8.1 中通过 cmd 获取天气？

Question

如何使用 获得天气结果cURL，为其分配一个变量以供以后使用？就像是：

# This doesn't work and is only a reference for what I want:

  set mytemperature= curl www.yahoo.com/(mycity)/weather.temperature  
  echo %mytemperature%

Answer 1

要将描述和温度保存在.bat文件中的变量中，还要从输出中删除字符??（十六进制：）并取回度数符号 [ ]：[0xB0 and 0xC2wttr.inLondon: +13??Cº

• @echo off 
  
  cd /d "%~dp0" && setlocal EnableDelayedExpansion
  
  >nul chcp 437 && set /p "_city=Please, enter some location, city, an attraction: " 
  for /f "delims= " %%d in ('forFiles /p "." /m "%~nx0" /c "cmd /c echo(0xF8"')do set "_o=%%~d"
  
  for /f tokens^=* %%i in ('^<con: curl https://wttr.in/%_city: =+%^?format^=%%l:+%%t\n -s
  ')do for /f %%T in ('^<con: cmd /u /c "echo\%%~i"^<nul^|find/v "%_o%"^|findstr /v ^,"
  ')do set "_dt=!_dt!%%~T"
  
  set "_description_temperature=!_dt::=: !" && call echo\!_description_temperature:+=!!_o!C
  
  timeout -1 & endlocal & goto :eof
  

  输出： London: +13°C

  rem :: char       hex code
  rem ::  ?    ==   0xB0   // removed in loop
  rem ::  ?    ==   0xC2   // removed in loop
  rem ::  °    ==   0xF8   // set _description_temperature=!_dt::=: !!_o!
  

老的：

• PowerShell：您可以使用@igor_chubin的解决方案

  (curl http://wttr.in/riodejaneiro -UserAgent "curl" ).Content

  或者

  powershell -nop -c "(curl http://wttr.in/riodejaneiro -UserAgent "curl" ).Content"

  
  
• 批处理文件：使用 whiteout 时，提供一些位置 [ curl http://wttr.in]，否则将假定您当前的位置显示数据：

  @echo off && title <nul && title %~nx0 && mode 128,45
  
  powershell -nop -c "(curl http://wttr.in/riodejaneiro -UserAgent "curl" ).Content"
  

  
  
• 命令：

  set _temp=cmd /a /v /c "curl wttr.in/RioDeJaneiro?format=^%t --silent"
  
  %_temp%
  

定义输出：

• $ curl wttr.in/London?format=%l:+%t\n 
    London: +13°C

  • 要指定您自己的自定义输出格式，请使用特殊的%-notation：

    c    Weather condition,
    C    Weather condition textual name,
    h    Humidity,
    t    Temperature (Actual),
    f    Temperature (Feels Like),
    w    Wind,
    l    Location,
    m    Moonphase ,
    M    Moonday,
    p    precipitation (mm),
    P    pressure (hPa),
    D    Dawn*,
    S    Sunrise*,
    z    Zenith*,
    s    Sunset*,
    d    Dusk*.
    
      (*times are shown in the local timezone)
    

    $ curl wttr.in/London?format=3
      London: ?? +7?C
    
    $ curl wttr.in/London?format="%l:+%c+%t\n"
      London: ?? +7?C
    

    
    
• 如果您想知道地球上最冷的永久有人居住的地区之一的名称并了解那里的天气：

  curl wttr.in/*

将温度转化为变量：

@echo off
chcp 1252 > nul
::Put your city here:
set City=Rio de Janeiro

set City_=%City: =-%
for /f "Delims=" %%a in ('curl --silent wttr.in/%City_%?format^=%%t') do set "CTemperature=%%a"
set CTemperature=%CTemperature:+=%
set CTemperature=%CTemperature:~0,-3%
echo The current temperature in %City% is %CTemperature% º Celcios
echo.
pause

将温度和天气描述转化为变量：

@echo off
chcp 1252 > nul
::Put your city here:
set City=Rio de Janeiro

set City_=%City: =-%
for /f "Delims=" %%a in ('curl --silent wttr.in/%City_%?format^=%%t') do set "CTemperature=%%a"
set CTemperature=%CTemperature:+=%
set CTemperature=%CTemperature:~0,-3%
for /f "skip=1 tokens=4*" %%a in ('curl --silent wttr.in/%City_%?0') do set "Description=%%a %%b"& goto :Next
:Next
echo.
echo The current temperature in %City% is %CTemperature% º Celcios "%Description%"
echo.
pause
