先给出代码

from scapy.sendrecv import sr1



class MyWindow(QWidget):
    def __init__(self):
        super().__init__()
        self.init_ui()
    def init_ui(self):
        self.ui=uic.loadUi("./spec_port_scan.ui")
        self.ip=self.ui.lineEdit

if __name__=='__main__':
    app=QApplication(sys.argv)
    w=MyWindow()
    w.ui.show()

    app.exec()

实现做好ui 界面 后与python相连接 

导入 相应的扫描程序  下面给出：有点缝合怪的感觉

from scapy.all import *

        if (send is None):
            continue
        # 如果是TCP数据包
        elif send.haslayer("TCP"):
            # 是否是 SYN+ACK 应答
            if send["TCP"].flags == "SA":
                # 发送ACK+RST数据包完成三次握手
                send_1 = sr1(IP(dst=target) / TCP(dport=port, flags="AR"), timeout=2, verbose=0)
                print("[+] 扫描主机: %-13s 端口: %-5s 开放" %(target,port))
