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：

根据 HTML：

HTML

要将带有文本的可点击元素标识为创建下载包，您可以使用以下任一定位器策略：

  • 使用xpath：

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

理想情况下，单击您需要为element_to_be_clickable()诱导WebDriverWait的元素，您可以使用以下任一Locator Strategies：

  • 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

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]

代替

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

因为您复制的类名是该对象的类名的汇编。每个类名用空格隔开。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。

然后做

b.click()

单击该元素。

尽管您可能希望等待该元素加载到页面上。
