Select and download files from ftp folder

mrjohn · 1st August 2012, 08:45

Hi ! I need to create one installer that connects to a ftp folder,gets a list of files there and then gives the option to download some of them.Is this possible with NSIS ?
Thanks !

Afrow UK · 1st August 2012, 11:23

Either write a plug-in to do it, call an existing DLL using the System plug-in or execute an existing command line executable (search Google for a DLL/EXE to use).

Thanks for the answer!

mrjohn · 1st August 2012, 17:08

For me it is hard to do that with NSIS,I don't know how to write plugin,I think i'll write a .NET app that will do the work,and I'll use it as an installer,the single problem is : there must be FRAMEWORK installed on the computer

Afrow UK · 1st August 2012, 19:13

Did you search for a DLL or command line FTP client for Windows? You can use either through NSIS.

T.Slappy · 2nd August 2012, 06:12

In present times Framework is installed on most machines.
If not then it is very easy to detect it, download and install using NSIS

mrjohn · 2nd August 2012, 06:42

Hi ! I've searched for command line but I found lot of things:commercial,mounting ftp to drive,etc,not something clearly,I'll do as T.Slappy suggested,thanks !

Err... Making your installer download and install .NET is not a better solution. For one thing, it requires a reboot. Second, it makes your installer much much more complex. Third, lots of people don't want to install .NET. Fourth, installation will take much longer.

There are plenty of free commandline-based FTP tools out there. http://www.ncftp.com/ncftp/ is my third google hit.

mrjohn · 2nd August 2012, 08:13

Thanks all of you'I don't want to annoy you,but for me the shortest road is the road I know,I tried ncftp but I couldn,'t connect to my ftp account with this tool,also I don't know how to add files into NSIS installer,it is too hard,i'll use .NET solution,thanks

Actually a fresh .NET installation does not require a reboot. Regarding FTP, one tool that comes to mind is wget. It is free and there is a Windows port (Google it) and it supports FTP file/folder listings IIRC.

Edit: cURL is another one.

Indeed wget works

PHP Code:


			
wget   --ftp-user=myuser --ftp-password=mypassw  ftp://mywebserver.com/update/

it lists files from a folder creating a file like this :

PHP Code:


			
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

<html>

<head>

<title>Index of /update on mywebserver.com:21</title>

</head>

<body>

<h1>Index of /update on mywebserver.com:21</h1>

<hr>

<pre>

</pre>

</body>

</html>

now how to get files into NSIS to let user select what files wants to download ?
Thanks !

MSG · 2nd August 2012, 15:30

You'll probably have to download the file list and direct output to a file:
SetOutPath $PLUGINSDIR
File ftpclient.exe
nsExec::Exec `"$PLUGINSDIR\ftpclient.exe" -param1 -param2 -etc > "$PLUGINSDIR\filelist.txt"`

And then parse that txt file using the macros listed in Appendix E of the manual: http://nsis.sourceforge.net/Docs/AppendixE.html

You could output what you find to a listbox with checkboxes, or some similar control. Google finds http://forums.winamp.com/showthread.php?t=318260 , which links to http://nsis.sourceforge.net/EmbeddedLists_plug-in .
You could of course also make a hundred hidden sections, then unhide & rename the sections after you get the filelist. One section for each file. Then you could just use the components page, instead of bothering with a checkbox'ed listbox control.

mrjohn · 3rd August 2012, 10:48

Thanks MSG !!!
I've done,I've created sections (I have max 7 ) default hidden (name ="") and I show them after getting the file list,I used SectionSetText.... all works, but instead using wget to download the files that shows a command window I want to use something with a real progressbar so I tried Inetc plugin, but I can't download the file with it,also with wget I can,this is the command I use :

PHP Code:


			
 inetc::get /caption "download" /popup "ftp://mywebserver*******" "ftp://myuser@mywebserver.info:mypassw@mywebserver*******update/upd_H_1_0_0_18.exe" "$EXEDIR\setup.exe"



    Pop $0 # return value = exit code, "OK" if OK

    MessageBox MB_OK "Download Status: $0"

I got error : URL Parts Error

Thanks !

Afrow UK · 3rd August 2012, 12:07

Put /end on the end of your inetc line.

Stu

mrjohn · 3rd August 2012, 12:22

Done, but the same error

thanks

Does it work without the /caption and /popup switches? If not then I would suspect your URL format is wrong as then I'd assume that error means InternetCrackUrl API failed.

Stu

mrjohn · 3rd August 2012, 14:29

Hi !
I tried something like this, rename user to
myuser
not
myuser@mywebserver.info

user is defined in cpanel as myuser@mywebserver.info,tested also with browser,simple name myuser doesnt work

So using simple myuser I can see the progressbar and then the message : Download Status:530:Login autenthication failed

PHP Code:


			
  inetc::get   "ftp://myuser:mypass@mywebserver*******public_html/pft/_public_/update/upd_H_1_0_0_18.exe" "$EXEDIR\setup.exe"

puting back the user to myuser@mywebserver.info got error : URL Parts Error

Thanks!

This worked for me:

code:
inetc::get "ftp://myuser:mypass@mywebserver.com/public_html/pft/_public_/update/upd_H_1_0_0_18.exe" "$EXEDIR\setup.exe" /end

You sure you put /end on correctly (as shown)?

Stu

mrjohn · 3rd August 2012, 19:16

not working,I think there must be a bug when user is defined as
myuser@mywebserver.info
not
myuser

Thanks

You can't have an @ in the username (or password). The FTP URI specification does not allow it.

It has to be:
ftp://<user>:<pass>@<host>/<path>

Stu

mrjohn · 4th August 2012, 05:51

In wget I use it like this and it works :

PHP Code:


			
 nsExec::Exec '"wget.exe"  --ftp-user=myuser@mywebserver.info --ftp-password=mypassw ftp://mywebserver*******update/ '

using in wget username myuser instead of myuser@mywebserver.info it doesn't work,so I think there is a bug in this plugin,also it is working with total commander,chrome,firefox,etc

Thanks!

As I said it's the FTP URI specification that does not allow the @ in the username when the username is in the URI. The @ is used as the delimiter between the username and password therefore it cannot allow more than one. This is not a fault of the plug-in. Try it in IE (or any other browser) for example. The reason it works with wget is because you're not specifying the username in the FTP URI. If you are stuck with that username then you will have to use wget instead of inetc.

mrjohn · 4th August 2012, 16:13

Thanks Afrow, I'll use wget.
