【Python】有道翻译的爬虫实现（前篇）

import requests

import json

url ="http://fanyi.youdao.com/translate_o?smartresult=dict&smartresult=rule"

data = {"i": "我喜欢学习",
"from": "AUTO",
"to": "AUTO",
"smartresult":"dict" ,
"client":"fanyideskweb" ,
"salt":"1532404170095" ,
"sign":"803db6c210654b2d1ab2292ae1ae3714" ,
"doctype":"json" ,
"version":"2.1" ,
"keyfrom":"fanyi.web" ,
"action":"FY_BY_CLICKBUTTION" ,
"typoResult": "false"}

headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.181 Safari/537.36",
"Referer": "http://fanyi.youdao.com/","Cookie": "[email protected]; JSESSIONID=aaaP2Qy4ztAfyfZRXzktw; OUTFOX_SEARCH_USER_ID_NCOO=570232601.9713346; fanyi-ad-id=47865; fanyi-ad-closed=1; ___rl__test__cookies=1532404170086"}

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

html_str = response.content.decode()

dict_str = json.loads(html_str)

print(dict_str['translateResult'][0][0]['tgt'])

在data那一块，每一次的salt和sign都不一样，所以比百度翻译的爬虫要多那么一点难度，在下一篇博客将会讲解。

这是博主试的另一个“人生苦短”的翻译。
