使用Selenium Python chrome webdriver发推文

Question

我不知道为什么这段代码无法正常工作。 该程序用于自动查找用户名，密码的各个字段，并为要发送的推文输入一些数据。 我正确选择了页面的元素，但无法在页面中输入数据并获得

NoSuchElement

例外。

from selenium import webdriver
import time
import os
import selenium

chromedriver = "mypathto/chromedriver"
os.environ["webdriver.chrome.driver"] = chromedriver
driver = webdriver.Chrome(chromedriver)

driver.get('https://twitter.com/login')
username = driver.find_element_by_name("session[username_or_email]")
password= driver.find_element_by_name("session[password]")
username.send_keys("myusername")
password.send_keys("password")



submit = driver.find_element_by_class_name("submit EdgeButton EdgeButton--primary EdgeButtom--medium")
submit.click()

autotw1= driver.find_element_by_id('tweet-box-home-timeline')
autotw1.send_keys("""Just a testing """)
print "Tweet probably sent"

driver.save_screenshot("mybotfunc.png")

Answer 1

您可以使用以下代码：

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

driver = webdriver.Chrome(executable_path = r'D:/Automation/chromedriver.exe')
driver.get("https://twitter.com/login")

username = driver.find_element_by_css_selector("input[placeholder='Phone, email or username']")
password= driver.find_element_by_css_selector("input[class='js-password-field']")
username.send_keys("your username")
password.send_keys("your password")

submit = driver.find_element_by_xpath("//button[text()='Log in']")
submit.click()

autotw1 = WebDriverWait(driver, 10).until(
EC.element_to_be_clickable((By.CSS_SELECTOR, "div[id='tweet-box-home-timeline']")))
autotw1.send_keys("""Just a testing """)  

tweet = driver.find_element_by_xpath("//span[@class='add-tweet-button ']//following-sibling::button[contains(@class,'tweet-action')]")
tweet.click()

为什么您的代码无法正常工作：

此名称有3个元素可用： session[username_or_email]
几个与此： session[password]
和2个具有此ID的： tweet-box-home-timeline
