2.2.路由版动态服务器和上面基本一样，多了个路由表（self.router_urls）而已
import reimport socketclass HttpServer(object): def __init__(self): # 路由表 self.router_urls = {"/test": "/test.py", "/user": "/test2.py"} def run(self): with socket.socket() as server: # 端口复用 server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) server.bind(("", 8080)) server.listen() while True: self.client_socket, self.client_address = server.accept() print(f"[{self.client_address}已上线]") self.handler() def response(self, status, body=None): with self.client_socket as socket: header = f"HTTP/1.1 {status}\r\n\r\n" socket.send(header.encode("utf-8")) if body: socket.send(body) def __static_handler(self, name): try: with open(f"./www{name}", "rb") as fs: return fs.read() except Exception as ex: print(ex) return None def __dynamic_handler(self, name): try: m = __import__(name) return m.application().encode("utf-8") except Exception as ex: print(ex) return None def handler(self): data = self.client_socket.recv(2048) if data: header, _ = data.decode("utf-8").split("\r\n", 1) # GET /xxx HTTP/1.1 ret = re.match("^\w+? (/[^ ]*) .+$", header) if ret: url = ret.group(1) print(url) # print url log body = None # 路由有记录：动态页面 if url in self.router_urls.keys(): url = self.router_urls[url] # 切片提取模块名 body = self.__dynamic_handler(url[1:-3]) else: # 静态服务器 if url == "/": url = "/index.html" body = self.__static_handler(url) # 没有这个页面或者出错 if body: self.response("200 ok", body) else: self.response("404 Not Found") else: # 404 self.response("404 Not Found") else: print(f"{self.client_address}已下线") self.client_socket.close()if __name__ == "__main__": import sys # 临时添加模块所在路径 sys.path.insert(1, "./www/bin") HttpServer().run()
