python - Selenium 类型错误: __init__() got an unexpected keyword argument 'service'

Question

我正在将我的应用程序从过程代码重构为 OOP。我正在尝试做这个驱动程序类。

更新:这适用于 Windows，但不适用于 Mac。

# IMPORTS

from os import system

from selenium import webdriver
from selenium.webdriver import Firefox, FirefoxOptions
from selenium.common.exceptions import NoSuchElementException

from selenium.webdriver.firefox.service import Service

class Driver():
    def __init__(self):
        #set executable path to driver
        self.dirname = os.path.dirname(__file__)
        if platform == "win32":
            self.executable_path = os.path.join(self.dirname, 'geckodriver.exe') #must save the gecko file to same directory where python is. path to geckodriver (firefox drive/motor) on your machine
            print("Gecko (Firefox) filepath is: ", self.executable_path)
        if platform == "darwin":
            self.executable_path = os.path.join(self.dirname, 'geckodriver') #must save the gecko file to same directory where python is. path to geckodriver (firefox drive/motor) on your machine
            print("Gecko (Firefox) filepath is: ", self.executable_path)
            
        self.service = Service(self.executable_path) 
            
        self.opts = FirefoxOptions()
        #self.opts.add_argument(f"--width={int(screen_width/4)}")
        #self.opts.add_argument(f"--height={int(screen_height/2)}")

        self.driver = Firefox(service=self.service, options=self.opts)
        
        self.driver.set_window_position(-10, 0)
        
        self.driver.get("https://google.com/")
    
Driver()

这会给我以下错误:

Traceback (most recent call last):
  File "/driverClass.py", line 72, in <module>
    Driver()
  File "/driverClass.py", line 66, in __init__
    self.driver = Firefox(service=self.service, options=self.opts)
TypeError: __init__() got an unexpected keyword argument 'service'

这是为什么呢？我正在将代码重构为 OOP。该代码之前在使用过程代码时有效。

这是来自工作代码:

# driver configs
service = Service(executable_path) #pass in path to geckodriver
opts = FirefoxOptions()
#opts.add_argument(f"--width={int(screen_width/4)}")
#opts.add_argument(f"--height={int(screen_height/2)}")
driver = Firefox(service=service, options=opts)

driver.set_window_position(-10, 0)
#driver.set_window_size(int(screen_width/4), int(screen_height))

driver.get("https://google.com/")

Answer 1

此错误消息...

TypeError: __init__() got an unexpected keyword argument 'service'

...暗示 service 是意外的关键字参数。

可能的原因，您还在使用Selenium v3.x 和关键字参数 服务不支持。

解决方案

自 Selenium 4.0 Beta 1 :

Deprecate all but Options and Service arguments in driver instantiation. (#9125,#9128)

因此您需要升级到Selenium 4.x
