从URL下载Windows批处理文件
我正在尝试使用Windows批处理文件从网站（例如）下载文件。我在编写下面的函数时收到一个错误代码：从URL下载Windows批处理文件,windows,batch-file,download,scripting,Windows,Batch File,Download,Scripting,我正在尝试使用Windows批处理文件从网站（例如）下载文件。我在编写下面的函数时收到一个错误代码： xcopy /E /Y "http://www.example.com/package.zip" 批处理文件似乎不喜欢http后面的“/”。有没有办法转义这些字符，这样就不会假定它们是函数参数？您不能通过http使用xcopy。尝试下载wget for windows。这可能会奏效。它是一个用于通过http非交互式下载文件的命令行实用程序。您可以在上一次我检查时，没有命令行命令从MS命令行连接
xcopy /E /Y "http://www.example.com/package.zip"
批处理文件似乎不喜欢http后面的“/”。有没有办法转义这些字符，这样就不会假定它们是函数参数？您不能通过http使用xcopy。尝试下载wget for windows。这可能会奏效。它是一个用于通过http非交互式下载文件的命令行实用程序。您可以在上一次我检查时，没有命令行命令从MS命令行连接到URL。尝试wget for Windows:
或URL2File:
在Linux中，可以使用“wget” 或者，您可以尝试VBScript。它们类似于命令行程序，但它们是由wscript.exe脚本主机解释的脚本。以下是使用VBS下载文件的示例：
使用ftp：
(ftp *yourewebsite.com*-a)
cd *directory*
get *filename.doc*
close
更改星号中的所有内容以适应您的情况。BATCH可能无法执行此操作，但如果您不想使用默认情况下未随Windows安装的工具，可以使用JScript或VBScript 本页的第一个示例下载VBScript中的二进制文件： 这个答案使用JScript（IMO，更好的语言）下载一个文件： 然后，批处理脚本可以调用下载该文件的JScript或VBScript
' Create an HTTP object
myURL = "http://www.google.com"
Set objHTTP = CreateObject( "WinHttp.WinHttpRequest.5.1" )
' Download the specified URL
objHTTP.Open "GET", myURL, False
objHTTP.Send
intStatus = objHTTP.Status
If intStatus = 200 Then
WScript.Echo " " & intStatus & " A OK " +myURL
Else
WScript.Echo "OOPS" +myURL
End If
@echo off

cd "C:\Program Files\GnuWin32\bin"
wget.exe --output-document C:\backup\file_%theFilename%.zip http://someurl/file.zip
您可以使用wget设置计划任务，将计划任务中的“运行”字段用作：
C:\wget\wget.exe -q -O nul "http://www.google.com/shedule.me"
这可能有点离题，但您可以使用Powershell轻松下载文件。Powershell附带现代版本的Windows，因此您不必在计算机上安装任何额外的东西。我通过阅读本页了解了如何做到这一点： 代码是：
$webclient = New-Object System.Net.WebClient
$url = "http://www.example.com/file.txt"
$file = "$pwd\file.txt"
$webclient.DownloadFile($url,$file)
我发现这个VB脚本： 工作起来很有魅力。配置为具有非常简单的函数调用的函数：
SaveWebBinary "http://server/file1.ext1", "C:/file2.ext2"
Function SaveWebBinary(strUrl, strFile) 'As Boolean
Const adTypeBinary = 1
Const adSaveCreateOverWrite = 2
Const ForWriting = 2
Dim web, varByteArray, strData, strBuffer, lngCounter, ado
On Error Resume Next
'Download the file with any available object
Err.Clear
Set web = Nothing
Set web = CreateObject("WinHttp.WinHttpRequest.5.1")
If web Is Nothing Then Set web = CreateObject("WinHttp.WinHttpRequest")
If web Is Nothing Then Set web = CreateObject("MSXML2.ServerXMLHTTP")
If web Is Nothing Then Set web = CreateObject("Microsoft.XMLHTTP")
web.Open "GET", strURL, False
web.Send
If Err.Number <> 0 Then
SaveWebBinary = False
Set web = Nothing
Exit Function
End If
If web.Status <> "200" Then
SaveWebBinary = False
Set web = Nothing
Exit Function
End If
varByteArray = web.ResponseBody
Set web = Nothing
'Now save the file with any available method
On Error Resume Next
Set ado = Nothing
Set ado = CreateObject("ADODB.Stream")
If ado Is Nothing Then
Set fs = CreateObject("Scripting.FileSystemObject")
Set ts = fs.OpenTextFile(strFile, ForWriting, True)
strData = ""
strBuffer = ""
For lngCounter = 0 to UBound(varByteArray)
ts.Write Chr(255 And Ascb(Midb(varByteArray,lngCounter + 1, 1)))
Next
ts.Close
Else
ado.Type = adTypeBinary
ado.Open
ado.Write varByteArray
ado.SaveToFile strFile, adSaveCreateOverWrite
ado.Close
End If
SaveWebBinary = True
End Function
函数SaveWebBinary（strUrl，strFile）”作为布尔值
常量adTypeBinary=1
常量adSaveCreateOverWrite=2
写入常数=2
Dim-web、varByteArray、strData、strBuffer、lngCounter、ado
出错时继续下一步
'下载包含任何可用对象的文件
呃，明白了
设置web=Nothing
设置web=CreateObject（“WinHttp.WinHttpRequest.5.1”）
如果web为空，则设置web=CreateObject（“WinHttp.WinHttpRequest”）
如果web为空，则设置web=CreateObject（“MSXML2.ServerXMLHTTP”）
如果web为空，则设置web=CreateObject（“Microsoft.XMLHTTP”）
web.Open“GET”，strURL，False
发送
如果错误号为0，则
SaveWebBinary=False
设置web=Nothing
退出功能
如果结束
如果web.Status为“200”，则
SaveWebBinary=False
设置web=Nothing
退出功能
如果结束
varByteArray=web.ResponseBody
设置web=Nothing
'现在使用任何可用方法保存文件
出错时继续下一步
设置ado=Nothing
设置ado=CreateObject（“ADODB.Stream”）
如果ado不算什么的话
设置fs=CreateObject（“Scripting.FileSystemObject”）
设置ts=fs.OpenTextFile（strFile，ForWriting，True）
strData=“”
strBuffer=“”
对于lngCounter=0至UBound（varByteArray）
写入Chr（255和Ascb（Midb（varByteArray，lngCounter+1，1）））
下一个
关闭
其他的
ado.Type=adTypeBinary
阿多，开门
ado.写varByteArray
ado.SaveToFile strFile，adSaveCreateOverWrite
阿多，结束
如果结束
SaveWebBinary=True
