Python Selenium返回unknownProtocolFound错误

我正在尝试使用Firefox Webdriver、Selenium和Python从[this GooglePlay direct link generator][1]下载一个APK文件

问题是，当Selenium尝试获取主页时，它会崩溃，并显示以下错误消息：

一种解决方案是url解析函数，在driver.get（url）之前调用每个url

然后你会像这样使用它

url = url_parser(url)
driver.get(url)

你就快到了

import requests
import time
from selenium import webdriver

def google_play_download(app_page_id):
    browser = webdriver.Chrome()
    browser.get("https://apps.evozi.com/apk-downloader/?id=" + app_page_id)
    browser.find_element_by_css_selector(".btn.btn-primary.btn-lg.btn-block").click()
    time.sleep(10)

    apk_link = browser.find_element_by_css_selector(".btn.btn-success.btn-block").get_attribute('href')
    browser.quit()
    for rnd in range(5):
        resp = requests.get(apk_link)
        if resp.headers['Content-Length'] == str(len(resp.content)):
            return resp.content


if __name__ == "__main__":
    content = google_play_download("com.instagram.android")
    f = open('file.apk', 'wb')
    f.write(content)
    f.close()

解析器无法在此行

apk\u link=browser中提取正确的url。请通过\u css\u选择器（“.btn.btn success.btn block”）查找\u元素。\u获取属性（'href'）

当您打印url时，它会显示

https://apps.evozi.com/apk-downloader/?id=com.instagram.android

把电话换成

apk_link = browser.find_element_by_css_selector(".btn.btn-success.btn-block")
ele=apk_link.get_attribute('href')

for rnd in range(5):
      resp = requests.get(ele)
      if resp.headers['Content-Length'] == str(len(resp.content)):
            return resp.content

代码将正常工作

驱动程序本身试图获取错误的URL，而不是我。我使用驱动程序获得正确的URL。在这个正确的URL的响应中，有一些链接（例如图像）和“iframe”，驱动程序试图下载它们并发出隆隆声！你能粘贴你的代码吗。然后我可以告诉您在哪里使用url解析器函数。您必须有某种链接中的for-link循环，它将url发送到webdriver…您有一个变量-url-连续五次向请求提供。url的内容应该来自哪里？你理解这个问题吗？问题在于页面的iFrame中存在错误的协议。超时对问题没有任何作用。谢谢。如果你运行这段代码，它会下载你想要的apk。。。您只需要正确的css选择器来获取id（表示成功的那个），然后您还需要睡眠。该网站本身表示，准备apk链接可能需要3分钟，因此在下载url存在之前查找该url不会返回任何下载url。顺便说一下，你应该考虑改变这个问题的话题，因为它从来就不是一个问题。我无法重现您最初发布的错误。试图将不存在的变量url传递给请求时，代码崩溃。

url = url_parser(url)
driver.get(url)
