Downloading a file from SSL url

Posted on 2016-08-25

I use curl to download files from URLs. For example I download the file abcd.zip from http://example.com/sites/abcd.zip using cURL.exe

curl.exe -O "http://example.com/sites/abcd.zip"

when I download files from SSL urls it gives me an error:

curl: (1) Protocol https not supported or disabled in libcurl.

I am attaching the curl utility which I am using.

Please let me know if there is a way to download SSL urls using curl utility or if there is a better way to download SSL files from urls similar to this way.

Thanks

I am not willing to download an EXE file that I don't know where it came from.  cURL has supported SSL/TLS for a long time.  However, you also need some additional files for it to work.  You may also need to download a set of 'root certificates'.

But you can download versions of cURL that do Not include SSL support.  Make sure that you have a version that includes it.  https://curl.haxx.se/download.html

How about a VBScript?

The proxy lines are only needed if behind a proxy.

Dim strArg
Dim objArgs

' Get argument from the command line
Set objArgs = WScript.Arguments
URL = objArgs(0)
saveTo = objArgs(1)

Set objXMLHTTP = CreateObject("MSXML2.ServerXMLHTTP.6.0")
'objXMLHTTP.setProxy 2, "http=proxy.mydomain.com:8080", ""
objXMLHTTP.open "GET", URL, False
objXMLHTTP.setOption 2, 13056
'objXMLHTTP.setProxyCredentials "username","password"
objXMLHTTP.send()

If objXMLHTTP.Status = 200 Then
Set objADOStream = CreateObject("ADODB.Stream")

objADOStream.Open
objADOStream.Type = 1 'adTypeBinary

objADOStream.Write objXMLHTTP.ResponseBody
objADOStream.Position = 0    'Set the stream position to the start

Set objFSO = Createobject("Scripting.FileSystemObject")
If objFSO.Fileexists(saveTo) Then objFSO.DeleteFile saveTo
Set objFSO = Nothing

objADOStream.SaveToFile saveTo
objADOStream.Close
Set objADOStream = Nothing
End if

Set objXMLHTTP = Nothing

Open in new window


This takes 2 parameters url and filename

sample:

cscript Getfile.vbs http://www.jeffld.com/ConsoleApp.zip ConsoleApp.zip

Open in new window

If you are on Windows, there are binary / pre-compiled versions you can download.  Look in the Windows section near the bottom of the page.

I tried Jeff's suggestion and I get this error:

c:\test\Getfile.vbs(22, 1) msxml6.dll: Not enough storage is available to comple
te this operation.

I have more than 300GB free space and I am trying to download a file which is 4 GB.

Thanks

Is there any specific reason you are using cURL for this - can you not look at other tools like wGet

If you look on the cUrl download you see this

With reference to the above both contain an EXE, however I found the first one (7MB) very annoying and chose the smaller one instead.

This works but it is compiled with OpenSSL so unless you use the -k switch (Verify Peer off) you might get an error. If you don't want to use the -k switch you can follow the instructions here (https://curl.haxx.se/docs/sslcerts.html) on how to setup your Windows system.
