Selenium Python登录Instagram的几个问题

Question

这是错误：

回溯（最近调用最后）：html" target="_blank">文件“C://users/anton/desktople/instabot/chrome instagram bot/main.py”，第8行，在my_driver.sign_in(username=username,password=password)文件“C:\users\anton\desktople\instabot\chrome instagram bot\chrome_driver_cli.py”，第39行，在sign_in username_input=self.driver.find_element_by_name（“username”）文件“d_element_by_name返回self.find_element(by=by.name,value=name）文件”C:\users\anton\desktop\instabot\chrome instagram bot\venv\lib\site-packages\selenium\webdriver\remote\webdriver.py“,第978行，在find_element'value':value}中）['value']文件”C:\users\anton\desktop\instabot\chrome instagram RAM bot\venv\lib\site-packages\selenium\webdrIver\remote\errorhandler.py“，第242行，在check_response引发exception_class（message,screen,stacktrace）selenium.common.exceptions.nosuchelementexception：message：没有这样的元素：找不到元素：{”method“：”CSS selector“,”selector“：”[name=“username”]“}（会话信息:chrome=79.0.3945.130)

这是密码

from selenium import webdriver
from selenium.common.exceptions import SessionNotCreatedException
from selenium.webdriver.common.keys import Keys


supported_versions_path = [

class ChromeDriver:

    def __init__(self):
        self.driver = self.__startup()


    def __startup(self):

        self.driver = None
        for current_checking_version in supported_versions_path:
            if self.driver is None:
                try:
                    self.driver = webdriver.Chrome(current_checking_version)
                    pass
                except SessionNotCreatedException:
                    self.driver = None
        return self.driver

    def sign_in(self, username, password):

        self.driver.get(instagram_link)
        frame = self.driver.find_element_by_tag_name("iframe")
        self.driver.switch_to.frame(frame)

        username_input = self.driver.find_element_by_name("username")
        # password_input = self.driver.find_element_by_name('password')
        # username_input.send_keys(username)
        # password_input.send_keys(password)
        # password_input.send_keys(Keys.ENTER)

    def get_page(self, url):
        self.driver.get(url)

    def quit(self):
        self.driver.quit()

你能帮我吗？

看来你们很亲密。Instagram上的username字段是一个ReactJS，因此您必须诱导WebDriverWait，然后使用以下任何一种定位器策略调用send_keys():

CSS_Selector:

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[name='username']"))).send_keys("Antonio_Sabatino")

XPath:

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@name='username']"))).send_keys("Antonio_Sabatino")

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
