14 爬虫 - Requests POST请求

最基本的GET请求可以直接用post方法

response = requests.post("http://www.baidu.com/", data = data)

传入data数据

对于 POST 请求来说，我们一般需要为它增加一些参数。那么最基本的传参方法可以利用 data 这个参数。

import requests

formdata = {
    "type":"AUTO",
    "i":"i love python",
    "doctype":"json",
    "xmlVersion":"1.8",
    "keyfrom":"fanyi.web",
    "ue":"UTF-8",
    "action":"FY_BY_ENTER",
    "typoResult":"true"
}

url = "http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule&smartresult=ugc&sessionFrom=null"

headers={ "User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36"}

response = requests.post(url, data = formdata, headers = headers)

print response.text

# 如果是json文件可以直接显示
print response.json()

运行结果:

{"type":"EN2ZH_CN","errorCode":0,"elapsedTime":2,"translateResult":[[{"src":"i love python","tgt":"我喜欢python"}]],"smartResult":{"type":1,"entries":["","肆文","高德纳"]}}

{u'errorCode': 0, u'elapsedTime': 0, u'translateResult': [[{u'src': u'i love python', u'tgt': u'\u6211\u559c\u6b22python'}]], u'smartResult': {u'type': 1, u'entries': [u'', u'\u8086\u6587', u'\u9ad8\u5fb7\u7eb3']}, u'type': u'EN2ZH_CN'}
