Perl Web 服务器初级编程[8]

                                                                                 localaddr=>'www.myserver.com',
                                                                                 localport=>80,
                                                                                 );
                        2.$httpd->accept  接受来自客户机连接请求，返回http::daemon::clientcoon对象
                        3.$httpd->url  由后台程序处理的主机和端口名     http://server:port/
                       4.$conn->get_request 读取来自客户机的http请求并返回一个http::request对象。能接受块传输和使用multipart/form-data编码的文档上载。一旦头 被读取就让get_request返回，然后就可以使用read_buffer来成块读数据。
                        5.$conn->read_buffer
                        6.$conn->reason  将get_request失败的原因返回
                        7.$conn->send_status_line 发送一个http响应状态行给客户机
                                            eg1:  $conn->send_status_line(rc_not_found);
                                                   #generate standard '404' response
                                            eg2:  $conn->send_status_line(404,“it wasn't there!“);
                                                   #eg2 has the same effect as eg1 has
                        8.$conn->send_file_response 试图打开，读和发送文档内容给客户机
                        9.$conn->send_file 试图发送传递的文档句柄内容给客户机
