Question

我正在尝试在Python中使用Selenium打开多个网页，并使用不同的帐户同时与这些页面进行交互，但是它仅在完成a1之后才开始a2。为什么它不能同时运行两个功能，所以我可以同时使用多个帐户与网站进行交互？

def function1(url,email,password):
 driver = webdriver.Chrome
 driver.get(website url)
 # LOG IN 

def function2(url,email,password):
 driver = webdriver.Chrome
 driver.get(website url)
 # LOG IN USING DIFFERENT ACCOUNT

a1 = multiprocessing.Process(target=function1(url,email,password))
a2 = multiprocessing.Process(target=function2(url,email, password))
a1.join()
a2.join()

Answer 1

您正在过程中调用该函数：

Process(target=function1(url,email,password))

function1(url,email,password)返回None

所以您实际上是在打电话：

Process(target = None)

如何使用多重处理。

a1 = multiprocessing.Process(target=function1, args=[url, email, password])
a2 = multiprocessing.Process(target=function2, args=[url, email, password])
a1.start()
a2.start()
a1.join()
a2.join()

multiprocessing.Process不会同时打开多个驱动程序并将其抓取
