[解決済み] Python によるヘッダ付き POST 送信

質問

結果を抽出するためのパラメータを含むPOSTを送信するPythonスクリプトを構築しようとしています。 fiddlerで、私は欲しいものを返すポストリクエストを抽出しました。ウェブサイトはhttpsのみを使用しています。

POST /Services/GetFromDataBaseVersionned HTTP/1.1
Host: www.mywbsite.fr

{"isLeftColumn":false,"lID":-1,"userIpCountryCode":"FR","version":null,"languageCode":"fr","siteCode":"frfr","Quotation":"eu"}

そして、私のPythonスクリプトです。

#!/usr/bin/env python
# -*- coding: iso-8859-1 -*-
import string
import httplib
import urllib2

host = "www.mywbsite.fr/sport/multiplex.aspx"
    params='"isLeftColumn":"false","liveID":"-1","userIpCountryCode":"FR","version":"null","languageCode":"fr","siteCode":"frfr","Quotation":"eu"'

headers = { Host: www.mywbsite.fr,
"Connection": "keep-alive",
"Content-Length": 129,
"Origin": "https://www.mywbsite.fr",
"X-Requested-With": "XMLHttpRequest",

}

url = "/Services/GetFromDataBaseVersionned"

# POST the request
conn = httplib.HTTPConnection(host,port=443)
conn.request("POST",url,params,headers)
response = conn.getresponse()

data = response.read()
print data

しかし、スクリプトを実行すると、このようなエラーが発生します。

socket.gaierror: [Errno -2] Name or service not known

どのように解決するのですか？

要求モジュールへのリンクをどうもありがとうございます。それはちょうど完璧です。以下は、私の問題に対する解決策です。

import requests
import json

url = 'https://www.mywbsite.fr/Services/GetFromDataBaseVersionned'
payload = {

# Adding empty header as parameters are being sent in payload
headers = {}
r = requests.post(url, data=json.dumps(payload), headers=headers)
print(r.content)
