无法在博客中找到“新帖子”按钮

Question

我正在尝试使用selenium和python自动发布博客

能够在浏览器中使用Inspect元素定位元素

import time
from selenium import webdriver
from selenium.webdriver.common.keys import Keys



browser = webdriver.Firefox()
browser.get('https://www.blogger.com/go/signin')
email = browser.find_element_by_id('identifierId')
email.send_keys("xxxxxx@gmail.com")
email.send_keys(Keys.RETURN)
time.sleep(5)
password = browser.find_element_by_name("password")
password.send_keys("xxxxxx")
password.send_keys(Keys.RETURN)
time.sleep(5)

newpost = browser.find_element_by_partial_link_text("editor")

posttitle = browser.find_element_by_name("K3JSBVB-C-b titleField textField K3JSBVB-C-a")

错误

无法找到元素：[name =“ K3JSBVB-C-b titleField textField K3JSBVB-C-a”]

Answer 1

此K3JSBVB-C-b class attribute看起来很动态，我建议改用New post文字。

相关的XPath表达式将类似于：

//a[text()='New post']

也考虑使用Explicit Wait，因为使用睡眠是antipattern you should be avoiding

new_post = WebDriverWait(browser, 10).until(
    expected_conditions.element_to_be_clickable(By.XPATH("//a[text()='New post']")))
new_post.click()
