python多进程(multiprocessing调用类函数)

#coding=utf-8

import os
import multiprocessing
from time import ctime, sleep
from selenium import webdriver


class testClass(object):

    def worker(self, interval, browser="Chrome", url="http://loginurl"):
        driver = eval("webdriver.%s()" % browser)
        driver.get(url)
        driver.find_element_by_id("txtUserName").send_keys("username")
        driver.find_element_by_id("txtPwd").send_keys("password")
        sleep(1)
        driver.find_element_by_id("btnLogin").click()
        print("I was at the %s %s" % (browser, ctime()))
        sleep(interval)
        print("end worker_2")


if __name__ == "__main__":
    for i in range(2):
        a = testClass()
        p = multiprocessing.Process(target=a.worker, args=(2, "Chrome"))
        p.start()
        sleep(2)

    print("The number of CPU is:" + str(multiprocessing.cpu_count()))
    for p in multiprocessing.active_children():
        print("child   p.name:" + p.name + "	p.id" + str(p.pid))
    print("END!!!!!!!!!!!!!!!!!")

如果要接收返回值，那么按下面脚本写：

import requests
import multiprocessing
from loguru import logger


def worker(url, headers, q):
    t = 0
    r = requests.get(url=url, headers=headers)
    text = eval(r.text)['Data'][-1]
    # print(text)
    q.put(text)


if __name__ == '__main__':
    q = multiprocessing.Queue()
    jobs = []
    p = multiprocessing.Process(target=worker, args=(url1, headers, q))
    jobs.append(p)
    p.start()
    p = multiprocessing.Process(target=worker, args=(url2, headers, q))
    jobs.append(p)
    p.start()
    for p in jobs:
        p.join()

    results = [q.get() for j in jobs]
    if results[0] == results[1]:
        pass
    else:
        logger.error("验证不通过!"))
