Windows批处理：将文件下载到当前文件夹

Question

我想从Windows 7中的.bat脚本下载文件，并将其放入当前文件夹（脚本所在的位置）。

我以这种方式尝试，但没有（好）结果：

    SET FILENAME = "name.ext"
    bitsadmin.exe /transfer "JobName" http://www.someurl.com/file.ext %cd%%FILENAME%

我懂了：

    Unable to add file - 0x80070005

为什么？ 我想字符串concat失败

（我知道在Win7中不推荐使用bitsadmin）

先感谢您！

Answer 1

您的问题是等号两边的空格。 它们同时包含在变量名称和变量内容中-加上缺少的反斜杠。

测试一下：

@echo off
SET "FILENAME=%~dp0\name.ext"
bitsadmin.exe /transfer "JobName" http://www.someurl.com/file.ext "%FILENAME%"

编辑：如果您以管理员身份执行此操作，请尝试上面的已编辑代码。
因为以提升的权限运行时，工作目录会更改。

当您说某事不起作用时，请报告所有错误消息，以便可以解决问题。

电源外壳

start-bitstransfer -source protocol://url.host/url.path -destination C:\destination\file.ext

来自cmd env

powershell -command "start-bitstransfer -source protocol://url.host/url.path -destination C:\destination\file.ext"

编辑 - 如何在不使用任何外部工具的情况下下载带有批处理文件的文件？

我认为Bitsadmin无法使用相对路径，因此您需要在本地文件中添加全名。

您还可以检查我的bitsadmin脚本，该脚本花费了大量的工作-它接受两个参数url和本地文件的路径（以及超时编号-默认为5）。您可以看到它在%CD%到本地文件名：

   @echo off
    setlocal
   :download

    if "%2" equ "" (
      call :help
      exit /b 5
   )

   if "%1" equ "" (
      call :help
      exit /b 6
   )
    set url=%~1
    set file=%~2
    rem ----
    if "%~3" NEQ "" (
        set /A timeout=%~3
    ) else (
        set timeout=5
    )

    bitsadmin /cancel download >nul
    bitsadmin /create /download download >nul 
    call bitsadmin /addfile download "%url%" "%CD%\%file%" >nul
    bitsadmin /resume download >nul 
    bitsadmin /setproxysettings download AUTODETECT >nul

    set /a attempts=0
    :repeat
    set /a attempts +=1
    if "%attempts%" EQU "10" (
        echo TIMED OUT
        endlocal
        exit /b 1
    )
    bitsadmin /info download /verbose | find  "STATE: ERROR"  >nul 2>&1 && endlocal &&  bitsadmin /cancel download && echo SOME KIND OF ERROR && exit /b 2
    bitsadmin /info download /verbose | find  "STATE: SUSPENDED" >nul 2>&1 && endlocal &&  bitsadmin /cancel download &&echo FILE WAS NOT ADDED && exit /b 3
    bitsadmin /info download /verbose | find  "STATE: TRANSIENT_ERROR" >nul 2>&1 && endlocal &&  bitsadmin /cancel download &&echo TRANSIENT ERROR && exit /b 4
    bitsadmin /info download /verbose | find  "STATE: TRANSFERRED" >nul 2>&1 && goto :finishing 

   w32tm /stripchart /computer:localhost /period:1 /dataonly /samples:%timeout%  >nul 2>&1
    goto :repeat
    :finishing 
    bitsadmin /complete download >nul
    echo download finished
    endlocal
   goto :eof

   :help
   echo %~n0 url file [timeout]
   echo.
   echo  url - the source for download
   echo  file - file name in local directory where the file will be stored
   echo  timeout - number in seconds between each check if download is complete (attempts are 10)
   echo.
   goto :eof

您还可以检查此jscript.net自编译混合文件（另存为.bat）：

@if (@X)==(@Y) @end /****** jscript comment ******

@echo off
::::::::::::::::::::::::::::::::::::
:::       compile the script    ::::
::::::::::::::::::::::::::::::::::::
setlocal
if exist simpledownloader.exe goto :skip_compilation

set "frm=%SystemRoot%\Microsoft.NET\Framework\"
:: searching the latest installed .net framework
for /f "tokens=* delims=" %%v in ('dir /b /s /a:d /o:-n "%SystemRoot%\Microsoft.NET\Framework\v*"') do (
    if exist "%%v\jsc.exe" (
        rem :: the javascript.net compiler
        set "jsc=%%~dpsnfxv\jsc.exe"
        goto :break_loop
    )
)
echo jsc.exe not found && exit /b 0
:break_loop


call %jsc% /nologo /out:"simpledownloader.exe" "%~dpsfnx0"
::::::::::::::::::::::::::::::::::::

import System;
var arguments:String[] = Environment.GetCommandLineArgs();
var webClient:System.Net.WebClient = new System.Net.WebClient();
print("Downloading " + arguments[1] + " to " + arguments[2]);
try {
    webClient.DownloadFile(arguments[1], arguments[2]);
} catch (e) {

        Console.BackgroundColor = ConsoleColor.Green;
        Console.ForegroundColor = ConsoleColor.Red;
        Console.WriteLine("\n\nProblem with downloading " + arguments[1] + " to " + arguments[2] + "Check if the internet address is valid");
        Console.ResetColor();
        Environment.Exit(5);
}

Answer 4

我自己解决了，没有使用FILENAME变量：

    bitsadmin.exe /transfer "JobName" http://www.someurl.com/file.ext "%cd%\name.ext"

Answer 5

只需使用Powershell，就不会有问题。

@echo off
setlocal enabledelayedexpansion
set _wdraft=%~dp0file.txt
set _dlwebf=http://df291a01bce923.sampledl.com/d/file.txt
Powershell -Command "(New-Object Net.WebClient).DownloadFile('%_dlwebf%','%_wdraft%')"
endlocal

最多可能需要20秒，或多或少取决于文件大小。

Answer 6

@echo off
SET "FILENAME=%~dp0\name.ext"
bitsadmin.exe /transfer "JobName" http://www.someurl.com/file.ext "%FILENAME%"
pause

这个作品。 换线

SET "FILENAME=%~dp0\name.ext" 

至

SET "FILENAME=%~dp0\Your File Name"
