Python的发送POST与头(Python send POST with header)

我尝试建立一个python脚本谁发送带有用于提取结果参数的POST。随着小提琴手，我已经提取POST请求返回谁是我想要的。该网站只使用HTTPS。

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

现在我的Python脚本：

#!/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

但是，当我跑我的剧本，我有这样的错误：

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

非常感谢您的链接请求模块。这只是完美。下面的解决我的问题。

import requests
import json

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

    "Content-Type": "application/json",
    "Accept": "*/*",

    "Accept-Encoding": "gzip,deflate,sdch",
    "Accept-Language": "fr-FR,fr;q=0.8,en-US;q=0.6,en;q=0.4",
    "Accept-Charset": "ISO-8859-1,utf-8;q=0.7,*;q=0.3",

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

Answer 2:

如果我们想自定义HTTP标头添加到POST请求 ，我们必须通过字典来的通过他们headers 参数。

下面是一个非空体和报头的示例：

import requests
import json

url = 'https://somedomain.com'
body = {'name': 'Maryja'}
headers = {'content-type': 'application/json'}

r = requests.post(url, data=json.dumps(body), headers=headers)

请参考这个答案为理念的更好的解释：

大多数这些都是自动的，不需要手动设置。请求会为你基于URL设置主机，接受被设置为可接受的默认值，接受语言很少需要在这些情况下，Referer的往往是即使未设置或过滤掉隐私的原因，所以网站不再依靠它是集，内容类型必须真实地反映你的帖子的内容（而不是JSON），所以请求后，该你这取决于你怎么称呼它，内容长度必须反映实际的内容长度，所以被要求为集它是在计算这个最佳位置，并连接一定要由库来处理，你不想要阻止它有效地重复使用的连接，如果它可以。
