我正在尝试使用selenium webdriver自动化路由器配置。下面是路由器页面的html：

我想从“频率”下拉框中选择“5GHz”选项。以下是执行此操作的代码：
self.browser_driver.get(self.base_url)
self.browser_driver.find_element_by_id("option_str1").click()
time.sleep(1)
Select(self.browser_driver.find_element_by_css_selector("select[name=\"wl_unit\"]")).select_by_visible_text("5GHz")
time.sleep(10)
self.browser_driver.close()
但是，只要从下拉菜单中选择了5GHz选项，我就会获得地址为router_ip/apply.cgi的空白页。我在这个网页上看到以下消息。
“router_ip”页面无效 “router_ip”没有发送任何数据。 ERR_EMPTY_RESPONSE
如何摆脱这个问题。在手动配置路由器期间，我没有遇到此问题。
答案 0 :(得分：0)
我正在将路由器凭据添加到python脚本中的base_url，这导致页面刷新问题。从下拉菜单中选择选项后，页面刷新发生，脚本无法再次打开身份验证URL。现在我在同一会话中使用身份验证URL登录到路由器后打开base_url（没有凭据）。现在以下代码正在运行：
self.base_url = "http://"+server_ip+"/"
self.auth_url = "http://" + "login" + ":" + "password" + "@" +server_ip+"/"
self.browser_driver.get(self.auth_url)
self.browser_driver.get(self.base_url)
self.browser_driver.find_element_by_id("option_str1").click()
time.sleep(1)
Select(self.browser_driver.find_element_by_css_selector("select[name=\"wl_unit\"]")).select_by_visible_text("5GHz")
time.sleep(10)
self.browser_driver.close()
