urllib通过Get请求爬取KeyWords页面信息

import baseSpider
import urllib

# www.baidu.com/s?wd=python

keyword = input("请输入你要查询的关键词:")
wd = {"wd":keyword}
# 这里需要做urlencode,以保证浏览器能够识别所有的字符信息
wd = urllib.parse.urlencode(wd)
#print(wd)

url = "http://www.baidu.com/s?"
url += wd

# downloadPage函数是封装好的函数，这里不做解释
html = baseSpider.downloadPage(url)

with open("baiduSearch.html", "wb") as f:
    f.write(html.encode('utf-8'))
