can anyone point out a tutorial that shows me how to do a POST request using urllib2 with the data being in JSON format?

urllib2 is a Python module that can be used for fetching URLs. It defines functions and classes to help with URL actions (basic and digest. authentication, redirections, cookies, etc) The magic starts with importing the urllib2 module.
1) urllib2 can accept a Request object to set the headers for a URL request, urllib accepts only a URL. 2) urllib provides the urlencode method which is used for the generation of GET query strings, urllib2 doesn't have such a function. This is one of the reasons why urllib is often used along with urllib2.
NOTE: urllib2 is no longer available in Python 3 You can get more idea about urllib.
The data returned by urlopen() or urlretrieve() is the raw data returned by the server. This may be binary data (such as an image), plain text or (for example) HTML. The HTTP protocol provides type information in the reply header, which can be inspected by looking at the Content-Type header.
Messa's answer only works if the server isn't bothering to check the content-type header. You'll need to specify a content-type header if you want it to really work. Here's Messa's answer modified to include a content-type header:
import json import urllib2 data = json.dumps([1, 2, 3]) req = urllib2.Request(url, data, {'Content-Type': 'application/json'}) f = urllib2.urlopen(req) response = f.read() f.close() If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
