I have to send bulk data items via url to process in server side.

Is it possible to send using get method?

 list1 = ["string1","string2","string3","string4"]
 list2 = ["domain_string1","domain_string2"]

 url = http://127.0.0.1/search?l=list1&l2=list2

How these lists should be passed?

These list of items will grow dynamically.sometime we will get 10 items in each list

suggest me the way?

In general, it's best to avoid long query strings in GET requests. A great question for reference on this is the SO question What is the maximum length of a URL?. You don't want to exceed 2000 characters.

If your items will always fit in this length, you can use urllib.urlencode to convert your parameters:

>>> list1 = ["string1","string2","string3","string4"]
>>> list2 = ["domain_string1","domain_string2"]
>>> allparams = map(lambda x: ("list1", x), list1)
>>> allparams += map(lambda x: ("list2", x), list2)
>>> import urllib
>>> urllib.urlencode(allparams)
'list1=string1&list1=string2&list1=string3&list1=string4&list2=domain_string1&list2=domain_string2'

Instead, you could use a POST request. I highly recommend the requests library:

import requests
r = requests.post("http://127.0.0.1/search", data=allparams)

  • The appropriate way to send them would be ?l1=string1&l1=string2&l2=string3, etc. That's the standard for URL formatting. – Jordan Mar 27 '12 at 15:57
  • Right, I forgot that you can duplicate query params. I've updated the answer. – jterrace Mar 27 '12 at 16:08

You can send it all with the same url variable name 

"http://localhost/search?urlvar=1&urlvar=2&urlvar=3"

request.GET.getlist("urlvar");
