Windows批处理文件从一个URL下载。

I am trying to download a file from a website (ex. http://www.example.com/package.zip) using a Windows batch file. I am getting an error code when I write the function below:

我正在尝试使用一个Windows批处理文件从一个网站下载一个文件(http://www.example.com/package.zip)。当我写下面的函数时，我得到一个错误代码:

xcopy /E /Y "http://www.example.com/package.zip"

The batch file doesn't seem to like the "/" after the http. Are there any ways to escape those characters so it doesn't assume they are function parameters?

批处理文件似乎不喜欢http之后的“/”。有没有什么方法可以避免这些字符，所以它不认为它们是函数参数?

With PowerShell 2.0 (Windows 7 preinstalled) you can use:

使用PowerShell 2.0 (Windows 7预安装)，您可以使用:

(New-Object Net.WebClient).DownloadFile('http://www.example.com/package.zip', 'package.zip')

Starting with PowerShell 3.0 (Windows 8 preinstalled) you can use Invoke-WebRequest:

从PowerShell 3.0开始(Windows 8预装)，您可以使用Invoke-WebRequest:

Invoke-WebRequest http://www.example.com/package.zip -OutFile package.zip

From a batch file they are called:

从批处理文件中调用它们:

powershell -Command "(New-Object Net.WebClient).DownloadFile('http://www.example.com/package.zip', 'package.zip')"
powershell -Command "Invoke-WebRequest http://www.example.com/package.zip -OutFile package.zip"

(PowerShell 2.0 is available for installation on XP, 3.0 for Windows 7)

(PowerShell 2.0可以在XP上安装，Windows 7的3.0版本)

There's a standard Windows component which can achieve what you're trying to do: BITS. It has been included in Windows since XP and 2000 SP3.

有一个标准的Windows组件可以实现你想要做的事情:比特。它已经被包括在Windows XP和2000 SP3中。

Run:

运行:

bitsadmin.exe /transfer "JobName" http://download.url/here.exe C:\destination\here.exe

The job name is simply the display name for the download job - set it to something that describes what you're doing.

作业名称只是下载作业的显示名称——将其设置为描述您正在做的事情的内容。

This might be a little off topic, but you can pretty easily download a file using Powershell. Powershell comes with modern versions of Windows so you don't have to install any extra stuff on the computer. I learned how to do it by reading this page:

这可能有点偏离主题，但是您可以很容易地使用Powershell下载文件。Powershell提供了现代版本的Windows，所以你不必在电脑上安装任何额外的东西。我通过阅读这一页学会了如何做到这一点:

http://teusje.wordpress.com/2011/02/19/download-file-with-powershell/

http://teusje.wordpress.com/2011/02/19/download-file-with-powershell/

The code was:

的代码是:

$webclient = New-Object System.Net.WebClient
$url = "http://www.example.com/file.txt"
$file = "$pwd\file.txt"
$webclient.DownloadFile($url,$file)

Last I checked, there isn't a command line command to connect to a URL from the MS command line. Try wget for Windows:
http://gnuwin32.sourceforge.net/packages/wget.htm

最后我检查了，没有命令行命令从MS命令行连接到一个URL。尝试Windows: http://gnuwin32 sourceforge.net/packages/wget.htm。

or URL2File:
http://www.chami.com/free/url2file_wincon.html

或URL2File:http://www.chami.com/free/url2file_wincon.html

In Linux, you can use "wget".

在Linux中，您可以使用“wget”。

Alternatively, you can try VBScript. They are like command line programs, but they are scripts interpreted by the wscript.exe scripts host. Here is an example of downloading a file using VBS:
https://serverfault.com/questions/29707/download-file-from-vbscript

或者，您可以尝试VBScript。它们类似于命令行程序，但它们是由wscript解释的脚本。exe脚本主机。这里有一个使用VBS下载文件的示例:https://serverfault.com/questions/29707/download-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

then

然后

AFAIK, Windows doesn't have a built-in commandline tool to download a file. But you can do it from a VBScript, and you can generate the VBScript file from batch using echo and output redirection:

AFAIK, Windows没有内置的命令行工具来下载文件。但是您可以从一个VBScript中完成，您可以使用echo和输出重定向来从批处理生成VBScript文件:

You cannot use xcopy over http. Try downloading wget for windows. That may do the trick. It is a command line utility for non-interactive download of files through http. You can get it at http://gnuwin32.sourceforge.net/packages/wget.htm

您不能在http上使用xcopy。尝试下载wget窗口。这可能会奏效。它是通过http进行非交互式下载文件的命令行实用程序。您可以在http://gnuwin32 sourceforge.net/packages/wget.htm获得它。

BATCH may not be able to do this, but you can use JScript or VBScript if you don't want to use tools that are not installed by default with Windows.

批处理可能无法做到这一点，但是如果您不想使用默认安装在Windows上的工具，那么您可以使用JScript或VBScript。

The first example on this page downloads a binary file in VBScript: http://www.robvanderwoude.com/vbstech_internet_download.php

这个页面的第一个示例下载了VBScript中的二进制文件:http://www.robvanderwoude.com/vbstech_internet_download.php。

因此，使用JScript (IMO，更好的语言)下载一个文件:Windows脚本主机(JScript):如何下载二进制文件?

Your batch script can then just call out to a JScript or VBScript that downloads the file.

Downloading files in PURE BATCH.

A lot of people are saying it's impossible, but it's not! I wrote a very simple function and it's working well for most URLs. It's using the "bitsadmin" command for downloading files which is part of Windows by default. (No need to download of install anything).

很多人都说这是不可能的，但事实并非如此!我编写了一个非常简单的函数，它对大多数url都很有效。它使用“bitsadmin”命令下载文件，默认情况下是Windows的一部分。(不需要下载安装任何东西)。

This question has very good answer in here. My code is purely based on that answer with some modifications.

这个问题在这里有很好的答案。我的代码完全基于这个答案，并进行了一些修改。

Save below snippet as wget.bat and put it in your system path (e.g. Put it in a directory and add this directory to system path.)

将下面的片段保存为wget。bat并将其放入您的系统路径(例如，将其放在目录中，并将该目录添加到系统路径中)。

You can use it in your cli as follows:

您可以在cli中使用它:

wget url/to/file [?custom_name]

wget url / /文件[? custom_name]

where url_to_file is compulsory and custom_name is optional

其中url_to_file是强制的，custom_name是可选的?

1. If name is not provided, then downloaded file will be saved by its own name from the url.
2. 如果没有提供名称，那么下载的文件将以自己的名称从url中保存。
3. If the name is supplied, then the file will be saved by the new name.
4. 如果提供了名称，则新名称将保存该文件。

The file url and saved filenames are displayed in ansi colored text. If that is causing problem for you, then check this github project.

文件url和保存的文件名显示在ansi彩色文本中。如果这对您造成了问题，那么请检查这个github项目。

@echo OFF
setLocal EnableDelayedExpansion

set Url=!Url:%%20=?!
set Url=!Url: =?!

if "%2"=="" set FileName=!FN!

echo.
echo.Downloading: [1;33m%1[0m to [1;33m\!FileName![0m

powershell.exe -Command wget %1 -OutFile !FileName!

goto :EOF
:LOOP
if "%1"=="" goto :EOF
set FN=%1
