二、socket 模拟 HTTP请求
import socketfrom urllib.parse import urlparseclass ParserUrl(object): ???''' ???对url进行解析，并返回域名和路径 ???''' ???def __init__(self, url): ???????self.url = url ???def get_host_path(self): ???????parser_url = urlparse(self.url) ???????host, path = parser_url.netloc, parser_url.path ???????if path: ???????????return host, path ???????else: ???????????return host, '/'class SocketHttp(object): ???''' ???需要一个ParserUrl对象，获取host和path ???建立连接返回http response字符串 ???http数据传递的时是以字节为单位的，所以需要编码 ???''' ???def __init__(self, parser_url): ???????self.host, self.path = parser_url.get_host_path() ???def set_socket(self): ???????self.client = socket.socket(socket.AF_INET, socket.SOCK_STREAM) ???????self.client.connect((self.host, 80)) ???????self.client.send("GET {} HTTP/1.1\r\nHost:{}\r\nConnection:close\r\n\r\n".format(self.path, self.host).encode("utf8")) ???@property ???def data(self): ???????self.set_socket() ???????data = b"" ???????while True: ???????????d = self.client.recv(1024) ???????????if d: ???????????????data += d ???????????else: ???????????????break ???????self.close_socket() ???????return data.decode("utf8") ???@property ???def html_content(self): ???????html_data = self.data ???????return html_data.split("\r\n\r\n")[1] ???def close_socket(self): ???????self.client.close()if __name__ == "__main__": ???url = ParserUrl('https://www.baidu.com/') ???socket_http = SocketHttp(url) ???print(socket_http.html_content)返回结果：
返回正常的字符串
