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 <a href="http://gnuwin32.sourceforge.net/packages/wget.htm" rel="nofollow">http://gnuwin32.sourceforge.net/packages/wget.htm</a>

Last I checked, there isn't a command line command to connect to a URL from the MS command line. Try wget for Windows: 
<a href="http://gnuwin32.sourceforge.net/packages/wget.htm" rel="nofollow noreferrer">http://gnuwin32.sourceforge.net/packages/wget.htm</a>

or URL2File: 
<a href="http://www.chami.com/free/url2file_wincon.html" rel="nofollow noreferrer">http://www.chami.com/free/url2file_wincon.html</a>

In Linux, you can use "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:

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.

The first example on this page downloads a binary file in VBScript:
<a href="http://www.robvanderwoude.com/vbstech_internet_download.php" rel="nofollow noreferrer">http://www.robvanderwoude.com/vbstech_internet_download.php</a>

This SO answer downloads a file using JScript (IMO, the better language):

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

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

Starting with PowerShell 3.0 (Windows 8 preinstalled) you can use <a href="https://technet.microsoft.com/en-us/library/hh849901(v=wps.620).aspx" rel="noreferrer"><code>Invoke-WebRequest</code></a>:

<pre><code>Invoke-WebRequest http://www.example.com/package.zip -OutFile package.zip

From a batch file they are called:

<pre><code>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"

<h2>CURL</h2>
With the build 17063 of windows 10 the CURL utility was added. To download a file you can use:
<pre><code>curl &quot;https://download.sysinternals.com/files/PSTools.zip&quot; --output pstools.zip
</code></pre>
<h2>BITSADMIN</h2>
It can be easier to use bitsadmin with a macro:
<pre><code>set &quot;download=bitsadmin /transfer myDownloadJob /download /priority normal&quot;
%download% &quot;https://download.sysinternals.com/files/PSTools.zip&quot; %cd%\pstools.zip
</code></pre>
<h2>Winhttp com objects</h2>
For backward compatibility you can use <a href="https://github.com/npocmaka/batch.scripts/blob/master/hybrids/jscript/winhttpjs.bat" rel="nofollow noreferrer">winhttpjs.bat</a> (with this you can perform also POST,DELETE and the others http methods):

</code></pre>

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

<pre><code>xcopy /E /Y "http://www.example.com/package.zip"
</code></pre>

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?

Windows batch file file download from a URL

命令行工具

Windows

Linux

我正在尝试从网站下载文件(例如)使用Windows批处理文件。当我写下面的函数时，我得到了一个错误代码：xcopy /E /Y "http://www.example.com/package.zip"批处理文件似乎不喜欢http后面的"/“。有没有办法对这些字符进行转义，这样它就不会假设它们是函数参数？
