Python网络编程 - http/https网页获取

 

 

 

用例:

import socket

 

def getDataBySocket(url):

    sock = socket.socket()

    ip_port = (url, 80)

    sock.connect(ip_port)

 

    print("建立连接的远程服务器地址:", sock.getpeername())

 

    #发送HPPT请求

    sock.send("GET / HTTP/1.1 ".encode("utf-8"))

    sock.send(("Host: " + url + " ").encode("utf-8"))

    sock.send((" ").encode("utf-8"))

 

    size = 1024

    while True:

        try:

            data = sock.recv(size)

            count = len(data)

            print("读取数据数量:", count)

 

            if count == 0:

                print("读数据完毕")

                break

 

            ret = str(data, encoding="utf-8")

            print(ret)

        except BaseException as exc:

            print("发生异常")

            break

 

if __name__ == '__main__':

    url = "www.baidu.com"

    getDataBySocket(url)
