Send request to REST Server using Python

Python’s requests library provides all necessary classes and methods to query internet resources, including REST server.

Client class

from requests import Request, Session, exceptions
import json

class Client:
    def __init__(self, base_url):
        self.base_url = base_url

    def query(self, uri, method, body):
        parameter = {}
        if body is not None:
            parameter.update(body)

        r = self._make_request(uri, method, parameter)
        rp = r.prepare()

        s = Session()
        resp = s.send(rp)
        return json.loads(resp.text)

    def _make_request(self, uri, method, body):

        headers = {
            'Accept': 'application/json'
        }

        r = Request(method.upper(), self.base_url + uri, headers=headers)

        if body:
            if r.method in ["POST", "PUT", "PATH"]:
                r.json = body
            else:
                r.params = body

        return r

Use the class

client = Client("http://api-domain.com/")
resp = client.query('login', 'POST', {'username': 'tester', 'password': 'tester'})
