问题描述

尝试使用Selify处理Instagram自动化页上的用户名输入字段时，出现意外结果。

编码：

from selenium import webdriver
from selenium.webdriver.common.by import By

patch = r'{patch to driver}'
driver = webdriver.Chrome(patch)
driver.get('https://api.instagram.com/oauth/authorize?client_id=965975207687609&redirect_uri=https://6b4c-46-39-51-57.ngrok.io/autos/index.php/&scope=user_profile,user_media&response_type=code')
elem = driver.find_element(By.NAME, 'username')

被重定向到的页面驱动程序是：https://www.instagram.com/accounts/login/?force_authentication=1&enable_fb_login=1&next=/oauth/authorize%3Fclient_id%3D965975207687609%26redirect_uri%3Dhttps%3A//6b4c-46-39-51-57.ngrok.io/autos/index.php/%26scope%3Duser_profile%2Cuser_media%26response_type%3Dcode 该页面上的元素名为用户名，但我收到了一堆错误消息：

推荐答案

Instagram Login Page上的用户名字段是一个ReactJS元素。因此，要发送字符序列，您必须为element_to_be_clickable()归纳WebDriverWait，并且可以使用以下Locator Strategies之一：

使用css_selector：

driver.get('https://api.instagram.com/oauth/authorize?client_id=965975207687609&redirect_uri=https://6b4c-46-39-51-57.ngrok.io/autos/index.php/&scope=user_profile,user_media&response_type=code') WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[name='username']"))).send_keys("Ignat")

使用XPath：

driver.get('https://api.instagram.com/oauth/authorize?client_id=965975207687609&redirect_uri=https://6b4c-46-39-51-57.ngrok.io/autos/index.php/&scope=user_profile,user_media&response_type=code') WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@name='username']"))).send_keys("Ignat")

注意：您必须添加以下导入：

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