httpconnection - unable to send data more than 1 mb

[mt.jijo]

Hi guys,

import httplib, urllib, e32, appuifw

def send_data(): #function to send the data to the server.

f=open('e:/file1.txt','rt')
test1=f.read()
params = urllib.urlencode({'data': test1})
headers = {"Content-type": "application/x-www-form-urlencoded","Accept": "text/plain"}
conn = httplib.HTTPConnection("www.myadd.com")
conn.request("POST", "/pys60/set_txt.php", params, headers)
conn.close()
e32.ao_yield()
appuifw.note(u"Data sent", "info")

def quit(): #exit function
script_lock.signal()

appuifw.app.menu = [(u"send data", send_data)]

appuifw.app.exit_key_handler = quit
script_lock = e32.Ao_lock()
script_lock.wait()

this is the code i am using for data sending from pys60 to server.

the problem is i am not able to send data more than about 1 mb at a time.

i want to send more data around 5-10 mb

can somebody help me

Thanks
Cyan !

hello mt.jijo

whats the error you are getting when you are sending that huge amount of data to the server. Actually long ago i also faced that sort of problem when uploading some photos using Python but that was my connection problem.

So what error you are getting??

hi Gaba,
i am getting a connetion timed out error when i tried with 5 mb of data but it works fine for 1 mb and less
is there any data limit for httpconnection?

Thanks

hello mt.jijo

oh i guess that is a connectivity problem only but i am not aware of the limitations of httplib when it comes to uploading of data.

BTW if you are uploading some sort of images or higher size data then you need a different php script at the server.

Moreover there are some more methods at the wiki which help in uploading the data, do check them.

Hi all !

Two suggestions:

• Increase application heap (how is your heap size ?)
• Make a raw socket connection (instead using urllib) and send the file in chunks.

I dont know if we have such limit in urllib ... searching ...

There may be several limits on the server, e.g. if you are using Apache + PHP on the server side:
- max_execution_time
- max_input_time
- post_max_size
- upload_max_filesize

Other web servers may have similar limits.

Hi mt.jijo,

You have to send data over server chunks by chunks it mean you have to fixed chunk size like 100 KB or so on.

hope this may be help.
