My application uses pictures and files (text and pictures) that I would like to keep up-to-date. I would like to put a folder on a web server and give users the possibility to connect and download the whole content: how can I automatically copy all these files to my device folder?

Thanks.

hi nufun

If i understand your problem correctly then what you can do is make a particlular time in your application using timers and then using the urllib module you can retrieve whatever you want to your device and use that in your application.

hope this helps you

It's not necessary that download is automatic (I put a menu button with "Update" and it's enough), what I need is to download all the remote files: could it be done just with python or do I need to put some script on the web server? (for example, I created a php script to list all the file into remote folder: am I in the right direction?).
Thanks.

If I understood the situation right you could do it simply with Python. Here is an example of how to download a file.

Ok, that's good, but in this way I guess I need to know the name of my up-to-dated files.
I think my main question is: is it possible to list all files in a remote folder just with python? I supposed something like

webserver = 'http://www.exemple.com/'
remote_folder = webserver + 'myfiles/'
f_list = os.listdir(remote_folder)
for file in f_list:
	url = remote_folder + file
	tempfile = "e:\\" + file
	try:
		print "Retrieving information..."
		urllib.urlretrieve(url, tempfile)
		lock=e32.Ao_lock()
		content_handler = appuifw.Content_handler(lock.signal)
		content_handler.open(tempfile)
		# Wait for the user to exit the image viewer.
		lock.wait()
		print "Video viewing finished."
	except:
		print "Problems."

but os.dir() doesn't work on remote folder (or I wasn't able to make it works! )
If so, I guess I need to retrieve my file list with php or something else.

Well, I'm not too knowledgeable when it comes to PHP so I'll suggest something else: have a list containing the names of the files that are to be updated, on the server. Read that list and use the names in it to download all the files you need.

Hi,

Well, after long time I see something regarding PHP on this Forum

Here is how you can list all files using PHP scripting, you can use this to make a function of your own.

function dirList ($directory) 
{

    // create an array to hold directory list
    $results = array();

    // create a handler for the directory
    $handler = opendir($directory);

    // keep going until all files in directory have been read
    while ($file = readdir($handler)) {

        // if $file isn't this directory or its parent, 
        // add it to the results array
        if ($file != '.' && $file != '..')
            $results[] = $file;
    }

    // tidy up: close the handler
    closedir($handler);

    // done!
    return $results;

}

Hope it helps,

Ok, I wrote about php but don't think I'm that good with it!
BTW your script is similar to mine, but I didn't think to put everything in an array!
Maybe this is exactly what I needed!
Thanks a lot!
I'll let you know if it works!!

I would be glad to help. I have done PHP tasks lately and so have the touch and feel of it

Sorry, but this is my really first attempt to use python with php.

I've called your function, insert my folder and if I try to print output I see my array of values.
Then I worked on python so I used

list_file = urllib.urlopen(url_update).read()
print list_file

but after it connected, nothing happens. After a while it tries to connect again and again and so on.
I guess I'm doing something wrong.
Here are my doubts:
PHP: should i print my result or just return it?
Python: is the .read() method correct or should I use something else?
Sorry if they are silly questions.

No problem, there is always opportunity to learn

You have to print the result on the client side or display it in any other form.
If you use http connection, the below line should do the job.

   response=conn.getresponse()

You need to print response variable here.

Just call the PHP script. read() function should do the job.

hi nufun

you are doing nothing wrong with the code because .read() function will only read the url link.
What you try is retrieve the link at your phones memory than open it.

Hope you got it

Ok, I got it working in some way (not still exactly what I want, but I'm working on it ).
Now my other problem is: how do I prevent my app from searching an access point when I'm already connected to one (it's actually asking me for an AP for every file it has to download)? And how I close connection with my connected access point when there is no file to download? I've tried with .close() method but it doesn't work.
Thanks for all your support.

You can't prevent, the python application to ask for access point, but you can make it ask just for once.

Use the following function to create a default access point for your application.

def set_accesspoint():
    apid = socket.select_access_point()
    if appuifw.query(u"Do you want to set this as default access point","query") == True:
        f = open('C:\\data\\wc\\apid.txt','w')
        f.write(repr(apid))
        f.close()
        appuifw.note(u"Saved default access point ", "info")
        apo = socket.access_point(apid)
        socket.set_default_access_point(apo)

For closing the connections, I would recommend to use iapconnect connection, as it has 2 functions - close and stop.

#conn.close() # this will disconnect, but leave gprs active
conn.stop() # this will shutdown the gprs connection

where conn is

conn = iapconnect.Connection()

Hope that helps,
