How do I send a POST request as a JSON?

by

If your server is expecting the POST request to be json, then you would need to add a header, and also serialize the data for your request…

Python 2.x

import json
import urllib2

data = {
        'ids': [12, 3, 4, 5, 6]
}

req = urllib2.Request('http://example.com/api/posts/create')
req.add_header('Content-Type', 'application/json')

response = urllib2.urlopen(req, json.dumps(data))

Python 3.x

If you don’t specify the header, it will be the default application/x-www-form-urlencoded type.
