Question

.db文件在提供的路径中创建。打印输出显示在终端窗口中，但.db文件中没有数据/模式。没有错误出现，语法似乎正确。这是代码。我不知道为什么，conn.commit()处于正确的区域。任何信息将不胜感激。

   c.execute("INSERT INTO secureDHCP (mac, vendorId, time, oData) VALUES (?, ?, ?, ?)",
          (src_mac, vendor, timeDate, optData))
   conn.commit()


s=socket.socket(socket.PF_PACKET, socket.SOCK_RAW, socket.ntohs(0x0800))

print("Input network interface")
interface = input()


def pkt_data(pkt):
    src_mac = pkt.getlayer(Ether).fields['src']
    url = 'http://api.macvendors.com/' + src_mac
    r = urlopen(url)
    vendor = r.read()
    timeData = str(datetime.now())
    full_options = pkt.getlayer(DHCP).fields['options']
    dhcp_options = [o for o in full_options if isinstance(o, tuple)]
    for x in dhcp_options:
        if x[0] in ('message-type', 'requested_addr', 'hostname'):
            optData = x[1]
            print('MAC: {} /// Vendor: {} /// Time {} /// optData: {}'.format(src_mac, vendor, timeData, optData))

sniff(iface=interface, prn=pkt_data, filter='udp port (67 or 68)', store=0)

终端输出：

`MAC: 00:00:00:00:00:00 /// Vendor: b'BRAND, Inc.' /// Other Data: 3
 MAC: 00:00:00:00:00:00 /// Vendor: b'BRAND, Inc.' /// Other Data: 192.168.1.4
 MAC: 00:00:00:00:00:00 /// Vendor: b'BRAND, Inc.' /// Other Data: b'HOSTNAME'`

首先，您没有调用类似make_table()的方法。其次，您致电make_table() 在其中，为什么要关闭conn？the_data()如何插入日期？请给出最小样本。下面的内容永远不会出错。

conn = sqlite3.connect(db_path)
c = conn.cursor()
c.execute('CREATE TABLE IF NOT EXISTS secureDHCP(mac VARCHAR(50), vendorId VARCHAR(50), time VARCHAR(50), oData VARCHAR(50)')
conn.commit()
c.execute("INSERT INTO secureDHCP (mac, vendorId, time, oData) VALUES (?, ?, ?, ?)",
      (src_mac, vendor, timeDate, optData))
conn.commit()
c.close()
conn.close()

创建数据库文件，没有数据/架构
