无法创建selenium.webdriver.Chrome的子类

Question

我刚刚接触 Python，想向 selenium.webdriver.Chrome 类添加一些额外的行为（我相信）

我想添加新行为

• 加载jQuery()
• 等待页面加载() 等等...

但似乎我什至无法创建子类

我的代码

from selenium.webdriver.chrome.options import Options
from selenium import webdriver
import time

class Chrome(webdriver.Chrome):
    def __init__(self):
        self.options = Options()
        self.driverPath = "drivers/chromedriver"
        self.jQueryJs = "Js/jquery-3.6.0.min.js"
        self.hasjQuery = False

        super().__init__(self, self.driverPath, self.options)

    def loadjQuery(self):
        with open(self.jQueryJs, errors='ignore') as jQueryJsSource:
            self.execute_script(jQueryJsSource.read())
            self.hasjQuery = True

    def pageWait(self):
            ready_state = self.execute_script('return document.readyState')
            times = 0
            while ready_state != "complete":
                time.sleep(0.5)
                times += 1
                if times > 20:
                    break
            time.sleep(2)
            return self

chrome = Chrome()
chrome.loadjQuery()
chrome.get("http://google.com")
chrome.waitForPageLoad()

这是输出错误

    super().__init__(self, self.driverPath, self.options)

    return ["--port=%d" % self.port] + self.service_args
TypeError: %d format: a number is required, not str

Answer 1

我找到了，需要做一些改变

• 从父级

  self

  调用中删除了

  __init__

  以正确匹配参数顺序（这导致了我在问题中发布的原始错误）

• 功能

  waitForPageLoad()

  原名是

  pageWait()

工作代码

from selenium.webdriver.chrome.options import Options
from selenium import webdriver
import time

class Chrome(webdriver.Chrome):
    def __init__(self):
        self.options = Options()
        self.driverPath = "drivers/chromedriver"
        self.jQueryJs = "/home/user/Documents/python-projects/lgbt/LGBT-AdvancedWebScrape/Resourse/Js/jquery-3.6.0.min.js"
        self.hasjQuery = False

        super().__init__( self.driverPath, options = self.options)

    def loadjQuery(self):
        with open(self.jQueryJs, errors='ignore') as jQueryJsSource:
            self.execute_script(jQueryJsSource.read())
            self.hasjQuery = True

    def pageWait(self):
            ready_state = self.execute_script('return document.readyState')
            times = 0
            while ready_state != "complete":
                time.sleep(0.5)
                times += 1
                if times > 20:
                    break
            time.sleep(2)
            return self

chrome = Chrome()
chrome.loadjQuery()
chrome.get("http://google.com")
chrome.pageWait()
