【爬虫基础】day01 get请求练习

# get请求练习
import urllib.request
import urllib.parse
import string


def get_params():
    url = "http://www.baidu.com/s?"
    params = {
        "wd": "中文",
        "key": "zhang",
        "value": "san"
    }
    # 要将字典中的":"变成字符串中的“=”
    str_parse = urllib.parse.urlencode(params)
    final_url = url + str_parse
    print(final_url)
    # https://www.baidu.com/s?wd=%E4%B8%AD%E6%96%87&key=zhang&value=san
    # 将带有中文的url转译成计算机可识别的url
    end_url = urllib.parse.quote(final_url, safe=string.printable)
    response = urllib.request.urlopen(end_url)
    # 读取返回的二进制文件
    content = response.read()
    # 将二进制文件行进源码解析
    origion = content.decode("utf-8")
    print(origion)
    # 将此文件保存在xml内
    with open("张三.html", "w", encoding="utf-8") as f:
        f.write(origion)


get_params()`在这里插入代码片`
