Dear All

I have tried the mobilenin code for uploading an image to URL as per his example .It works great while uploading to image to mobilenin site. but when i tried to upload on my site it gives some forbidden 403 and sometime some eror 503. when i checked to error log on server it showed no such directory(actually directories are there which i have written in my python code) and the second error is of gnuncompress(): error...what is this? can anyone help me.

Hi

gnuncompress(): error...

Means that zlib module isn't loaded on your server. Ask your admin

when i checked to error log on server it showed no such directory

In Jurgen's example, it uses a beijing directory. So it needs to be present(with enough rights to write inside) in the same directory than the PHP script.

Dear all,

When I enter the Images Directory, I got the following error:

IOError:[Error13] Permission denied: 'e:/Images'

Anyone? Thx.

[lfd]

Hi elbarto Simpsons and welcome to the forum

IOError:[Error13] Permission denied: 'e:/Images'

Try 'e:\\Images'

Hi folks,

Since it is not the first time one ask for help with image upload I made a python and server script for you. So far it has worked everywhere I tried it. My method is different than Jurgen's. I use base64 encoding instead of zlib.

You can find it at http://students.oamk.fi/~dlefevre/th...d-image-to-url

Dear LFD,
It work fine with a picture size under 100k, but it does not work with picture with the size over 500K, any idea?

[lfd]

Hi elbarto Simpsons,

You might have limitations on your server.

Running the same script on my desktop machine I managed to upload a 5Mb mp3 file to my server. I have don't a S60 phone with me tonight to confirm but it should be the same since it's only Python.

It might be a limitation in pys60 too: python2.2 in desktop (linux 2.6) seems to POST happily 7.5 megabytes (8 MB is too much).

Same method in 6630 fails if POST size is 30 kB.

Here is the function (simplified version):

    def _send_request(self, operation, params):
        """
        Send HTTP-request to the server using httplib.
        """
        params['rpc_op'] = operation
        params = urllib.urlencode(params)
        headers = {"Content-type": "application/x-www-form-urlencoded",
                   "User-Agent": self.ua,
                   }
        conn = httplib.HTTPConnection(self.host)
        conn.request("POST", self.script, params, headers)
        response = conn.getresponse()
        data = response.read()
        conn.close()
        return data

I have to do more tests. Perhaps the right answer is to use multipart/form-data.

I wrote a Flickr uploader for 3rd edition PyS60 devices (Teemu's Fupper and all the other similar applications that I found are for 2nd edition) and that's how I did all the image uploading. I think the largest file I moved off my phone was around a 1 MB and it never had any problems.

I got the code (below) from uploadr, but that author cites it originally coming from here: http://www.voidspace.org.uk/atlantib...thonutils.html. I can't find where specifically on this site it came from, but there's a lot of modules. I'll just post the two functions below and if there's more questions about them, I can provide some more code or poke about on that voidspace site some more.

Yes, multipart/form-data works fine up to 2 MB or something (tested in N70).

But in my example where
Content-type: application/x-www-form-urlencoded
and
params = urllib.urlencode(params)
request fails if the the size of params (in bytes) exceeds about 20-30kB.

Here is the end of the traceback. AssertionError?

result, rinfo = self._send_request(self.rpc_name(), params)
File "C:\System\Apps\PlokIn\Comm.py", line 136, in _send_request
data = response.read()
File "E:\system\libs\httplib.py", line 238, in read
s = self.fp.read()
File "E:\system\libs\httplib.py", line 794, in read
assert not self._line_consumed and self._line_left
AssertionError

Currently I don't have time to examine what raises this error, I'll change the code to use _send_multipart_request().

Hi fellows,

It just came to my mind that I actually used already multipart/form-data upload with a different project.

I found a library HTTPFileUploader long time ago and I'm sorry that I can't tell you who wrote it. So here comes a good library to add in your tool box.

Download it HTTPFileUploader.txt and rename HTTPFileUploader.txt to HTTPFileUploader.py. Then simply push it on your phone and install it as a library (2nd edition) or create an installation package with ensymble to simplify the task (3rd edition)

Usage:

import os
from HTTPFileUploader import * # uploader class
 
# path of the file to download
filePath = "001.jpg"
 
# new HTTPFileUploader instance
uploader = HTTPFileUploader('yourServer.xxx', port = 80) # port optional if 80
 
# set page
uploader.setPage('/uploaderFolder/file_uploader.php')
 
# Add fields in HTTP: ex file name for or past example
uploader.setField("fileName", os.path.split(filePath)[1])
 
# upload file - returns True or False.
if not uploader.uploadFile(filePath, "picture"):
    print uploader.getResult()

And a php source for the server

PHP Code:

<?php
# Copyright (c) 2007 LEFEVRE Damien
# file_uploader.php implementation

// In this example a directory "images" needs to be present on the same directory where
// image_uploader.php is, with the necessary rights for the script to write data inside
$content_dir = 'images/';
$filename = Null;

if(isset($_POST['fileName'])){
    $filename = $_POST['fileName'];
}

if(isset($_FILES['picture'])){
    if ($filename == Null){
        $filename = $_FILES['picture']['name'];
    }
    if( !move_uploaded_file($_FILES['picture']['tmp_name'], $content_dir . $filename) ){
        exit("Couldn't write the file in $content_dir");
    }
}
else{
    // something when wrong
    exit("False");
}
// return
echo "True";
?>

After, it is up to you to hack that codes to make them do what you want. I also added a note on my page http://lfdm.net/thesis/index.php/Code-snippets
