how to loop data in urllib?

[pythonlover]

Hello PyLovers,
I was trying to pass each line of the file as a value to the data. I am just pasting that part of the file. Please advise.

[line refers each line and that is the value that should be passed in the payload.

def interfaces():
   f = open ('interfaces', 'w')
   with open("uniquenames") as myfile:
       for line in myfile:
           print line
           payload = "{\"data\": {\"Attributes\": [\"name\", \"speed\", \"status__name\"], \"Filters\": {\"device__name\":\" "line" \" }, \"Type\": \"DevicePort\", \"page_size\": 2}}"
           headers = {"Content-Type": "application/json"}
           request = urllib2.Request(url, payload, headers)
           response = urllib2.urlopen(request)
           d = response.read()
           print d

You don't do a request call in a loop,you first build payload json then send request with payload to server.
url should not come into the function from global namespace,use argument in function interfaces(url).
Use Requests,and not urllib.
Eg.

>>> import requests

>>> line = 'Super PC'
>>> json_data = {"device__name": line, "Type": "DevicePort", "page_size": 2}
>>> headers = {'Content-type': 'application/json'}
>>> r = requests.post('http://httpbin.org/post', headers=headers, json=json_data)
>>> r.status_code
200
>>> r.json()['json']['device__name']
'Super PC'

But I have a file with a list of devices that I want to run each one as a argument to the "device__name": and get the data. How do I do that?

If you need to send 1 and 1 request you can do that in a loop.
Server will probably complain if it get to many requests in a short time,
if it dos set a little delay between each request.
Eg:

>>> import requests
>>> devices = ['Super pc', 'Ninja pc', 'Alien pc'] 
>>> for item in devices:
...     json_data = {"device__name": item, "Type": "DevicePort", "page_size": 2}
...     r = requests.post('http://httpbin.org/post', headers=headers, json=json_data)
...     r.status_code
...     r.json()['json']['device__name']
...     
200
'Super pc'
200
'Ninja pc'
200
'Alien pc'

This actually worked. Thank you!
