python利用爬虫实现有道翻译

import requests
from bs4 import BeautifulSoup

word = input("请输入你所要翻译语句")
url = "http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule"

key = {
    "i": word,
    "from": "AUTO",
    "to": "AUTO",
    "smartresult": "dict",
    "client": "fanyideskweb",
    "doctype": "json",
    "version": "2.1",
    "keyfrom": "fanyi.web",
    "action": "FY_BY_REALTIME",
    "typoResult": "true"

}
html = requests.post(url, data=key)
js = html.json()
print("翻译结果：" + js['translateResult'][0][0]['tgt'] + '\n')

# soup=BeautifulSoup(html.content,"html.parser")
# print(soup)
