Python爬虫实现百度翻译功能过程详解

from urllib import request,parse
import json


def translate(content):
  url = "http://fanyi.baidu.com/sug"
  data = parse.urlencode({"kw":content}) # 将参数进行转码
  headers = {
    'User-Agent': 'Opera/9.80 (Android 2.3.4; Linux; Opera Mobi/build-1107180945; U; en-GB) Presto/2.8.149 Version/11.10'
  }
  req = request.Request(url,data=bytes(data,encoding="utf-8"),headers=headers)
  r = request.urlopen(req)
  # print(r.code) 查看返回的状态码
  html = r.read().decode('utf-8')
  # json格式化
  html = json.loads(html)
  # print(html)
  for k in html["data"]:
    print(k["k"],k["v"])

if __name__ == '__main__':
  content = input("请输入您要翻译的内容：")
  translate(content)
