我想在另一个线程中运行pyshark

问题描述

我想在pyshark的另一个线程中进行捕获。 它在同一线程中运行良好，但是当我在其他线程中运行时，它在pyshark中的第226行[*]处停止，并且无法正常工作。

我当前的代码就是这样描述的。

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
import datetime
import time
import pyshark
import subprocess
from module.iwlibs import Wireless
import concurrent.futures


def modeMonitor(wlan):
    wlanNic = Wireless(wlan)
    if wlanNic.getMode() != 'Monitor':
        try:
            subprocess.check_call(["ip","link","set",wlan,"down"])
            subprocess.check_call(["iwconfig","mode","monitor"])
            subprocess.check_call(["ip","up"])
        except subprocess.CalledProcessError as e:
            print(str(e))
            sys.exit()


def captest(wlanNic):
    cap = pyshark.LiveCapture(interface=wlanNic)
    print("start capture...")
    for pk in cap.sniff_continuously():
        print("Source Address : " + str(pk["WLAN"].get_field("sa")))
        print("RSSI : " + str(pk["RAdioTAP"].get_field("dbm_antsignal")))


def Nowtime():
    while True:
        dt_Now = datetime.datetime.Now()
        print(dt_Now.strftime('%Y/%m/%d %H:%M:%s'))
        time.sleep(1)


if __name__ == "__main__":
    try:
        executor = concurrent.futures.ThreadPoolExecutor(max_workers=2)
        modeMonitor("wlan1")
        executor.submit(Nowtime)
        executor.submit(captest,"wlan1") #Doesn't work... Stopping [*] line 226.
        #captest("wlan1") #work well But I want to do something else after this.
    except Exception as ex:
        print(ex)

此外，执行环境如下。

Python 3.7.3 皮沙克0.4.2.11。
