selenium.common.exceptions.NoSuchElementException: 消息: 没有这样的元素: 无法定位元素: {"method":"css selector","selector":".ui flu~"}

Question

这是我使用的代码：

import requests as r, sys as sus, bs4 as bs, webbrowser as wb
from selenium import webdriver as wd

dr = wd.Chrome()

b = r.get("https://uupdump.net/fetchupd.php?arch=amd64&ring=wif&build=latest").text
s = bs.BeautifulSoup(b, features="html.parser")

if "/selectlang.php?id=" in b:
    l = b.split("/selectlang.php?id=")[1].split('"')[0]
    u = f"https://uupdump.net/download.php?id={l}&pack=es-es&edition=professional"
    print(u)
    b = r.get(u).text
    s = bs.BeautifulSoup(b, features="html.parser")
    print(s)
    dr.get(u)
    b = dr.find_element_by_class_name('ui fluid right labeled icon primary button')

这是错误：

uupdump.py:17: DeprecationWarning: find_element_by_* commands are deprecated. Please use find_element() instead
  b = dr.find_element_by_class_name('ui fluid right labeled icon primary button')

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":".ui fluid right labeled icon primary button"}

我想要的是使用 Selenium 从 uupdump.net 中通过其 class 名称找到一个按钮，以下载最新版本的 zip 文件。

Answer 1

要找到您想要的特定按钮元素，您可以执行以下操作：

b = dr.find_elements_by_class_name('primary')[-1]

而不是

b = dr.find_element_by_class_name('ui fluid right labeled icon primary button')

因为您复制的 class 名称是该对象的 class 名称的汇编。每个 class 名称由 space 分隔。因此，使用最独特的标识符 'primary' 我们能够将元素缩小到 3 个，并看到您想要的元素是最后一个。

然后

b.click()

单击该元素。

尽管您可能想要等待该元素加载到页面上。

Answer 2

根据 HTML:

将带有文本的可点击元素识别为创建下载包 您可以使用以下任一项 :

使用 xpath:

b = dr.find_element(By.XPATH, "//button[@class='ui fluid right labeled icon primary button' and contains(., 'Create download package')]")

最好点击你需要诱导的元素WebDriverWait for the and you can use either of the following :

使用 XPATH:

b = WebDriverWait(dr, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[@class='ui fluid right labeled icon primary button' and contains(., 'Create download package')]")))

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

selenium.common.exceptions.NoSuchElementException: 消息: 没有这样的元素: 无法定位元素: {"method":"css selector","selector":".ui flu~"}

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":".ui flu~"}
