Issue with urllib on Nokia E90, Python 1.4.3

[lancew]

Hi everyone,
I have been trying to use urllib and am encountering problems. I have tried uninstalling Python and reinstalling and still it fails.
Below is the code that fails, I have other actual useful code that I want to use this for, but to simplify fault-finding I wrote this short bit of code and it failed too.



import urllib
print "hello"
f = urllib.urlopen("http://www.python.org").read()
print f

----
The output and errors I see are below:


hello
Traceback (most recent call last):
File "ped.py", line 908, in run_click
File "E:\Python\Urllib.py.py", line 3, in ?
f = urllib.urlopen("http://www.python.org").read()
File "c:\resource\urllib.py", line 43, in urlopen
return _urlopener.open(url)
File "c:\resource\urllib.py", line 123, in open
return getattr(self, name)(url)
File "c:\resource\urllib.py", line 229, in open_http
h.endheaders()
File "c:\resource\httplib.py", line 454, in endheaders
self._send_output()
File "c:\resource\httplib.py", line 405, in _send_output
self.send(msg)
File "c:\resource\httplib.py", line 385, in send
self.connect()
File "c:\resource\httplib.py", line 355, in connect
socket.SOCK_STREAM):
File "c:\resource\socket.py", line 229, in getaddrinfo
r_host = gethostbyname(host)
IOError: [Errno socket error] (0, 'getaddrinfo failed')

Any assistance would be really appreciated.

Traceback (most recent call last):
File "ped.py", line 908, in run_click

Try whether it runs outside Ped. I had a small script which failed inside Ped and spent the whole evening trying to debug a perfectly ok script - in vain, naturally

Summary:
save as a file and run it from PythonShell.

Cheers,

Hi lancew,

Nothing is wrong with your code

Jouni is right! There are instances when trying to run scripts on PED fails, especially with scripts related to Access points and Upload data scripts, it usually returns the error below.

(0, 'getaddrinfo failed')

However the same script will run perfectly fine on the PythonScript Shell.

Thanks for the re-assurance.
I tried it not using PED and it worked ok.

However... my original code that is talking to a web API (JSON) still dies.


I shall do appropriate screengrabs etc and post them here.
It works to my base url www.lancewicks.com but then it fails when reading into my NoseRub install. www.lancewicks.com/noserub/ and deeper.

Thanks for the input.

Hmmm.... interesting.
I just ran the code I posted and it ran okay.
I edited the URL to my API url and it worked ok.

I then added import JSON and tried to read "f" using Json and it died.
When it dies it brings up the slect AP dialog twice. It only does it once when it works. Weird.

No unable to run at all. I am rebooting my phone to see if that helps.

I have a similar problem, but with Ensymble. My code works fine in Python Script Shell, but when I package it into a sis file, it stops at the following line:

onlineFile = urllib.urlopen(URL + Filename")

It doesn't even try to connect to the web (there is an icon that shows up normally, when it tries to connect). Is there some extra procedure that I missed? I use Jurgen Scheible's default access point setter code. Maybe that's causing some trouble?

Any help is appreciated!

Best,

Just to add some details to my previous post:

I'm using a 3rd Ed machine (Nokia 5500) and using Ensymble v0.26.
The program closes when it gets to the aforementioned line of code.

hi hyon
it will be better if you tell the dibo about the procedure you followed to make your sis file.

[croozeus]

onlineFile = urllib.urlopen(URL + Filename")

You have a problem in the code.
For extracting data from HTML documents using urllib, it goes like this

For eg.

sock = urllib.urlopen("http://diveintopython.org/"

You might need to modify your code to

onlineFile = urllib.urlopen(URL + "Filename")

Or try having the whole string in one variable and then try like

URL= URL + "Filename"
onlineFile = urllib.urlopen(URL)

Hope that helps

The following is a test script that I wrote solely to test the urllib.urlopen command in a sis file:

import appuifw
import urllib
import os
import e32

file = urllib.urlopen(u"http://www.mobilenin.com/pys60/resources/ex_upload_file_to_url.py")
fileContent = file.read()
file.close()

newFile = open(u"e:\\path.py", 'w')
newFile.write(fileContent)
newFile.close()

and the following is how I packaged it using Ensymble v0.27:

ensymble.py py2sis --autostart --runinstall downloadTest.py

Also, I used Symbian Open Signed to sign it.

Please tell me what I am doing wrong!

You have to specify the capabilities when creating the sis file with Ensymble. So it should be like:

ensymble.py py2sis  --caps=LocalServices+NetworkServices+ProtServ+ReadUserData+SwEvent+UserEnvironment+WriteUserData+ReadDeviceData+WriteDeviceData --autostart --runinstall downloadTest.py

[hyon]

ah ha! it works now.

although, it is VERY redundant, since i specify those capabilities on symbian signed...

thank you all for your help!
