Python 单击按钮并用Selenium和PhantomJS填充表单

我有一个简单的任务，我想自动化。我想打开一个URL，点击一个按钮进入下一页，填写搜索词，点击“搜索”按钮，打印出结果页的URL和源代码。我写了以下内容

from selenium import webdriver
import time

driver = webdriver.PhantomJS()
driver.set_window_size(1120, 550)

#open URL
driver.get("https://www.searchiqs.com/nybro/")
time.sleep(5)

#click Log In as Guest button
driver.find_element_by_id('btnGuestLogin').click()
time.sleep(5)

#insert search term into Party 1 form field and then search
driver.find_element_by_id('ContentPlaceholder1_txtName').send_keys("Moses")
driver.find_element_by_id('ContentPlaceholder1_cmdSearch').click()
time.sleep(10)

#print and source code
print driver.current_url
print driver.page_source
driver.quit()

我不确定哪里出了问题，但我已经学习了一些关于如何点击按钮和填写表单的教程。我得到了这个错误

它仍然会引起这个错误

回溯（最近一次呼叫最后一次）：
文件“phant.py”，第14行，在
EC.元素的存在位置（（By.ID，“btnGuestLogin”））
文件“/usr/local/lib/python2.7/dist-packages/selenium/webdriver/support/wait.py”，第80行，直到
引发TimeoutException（消息、屏幕、堆栈跟踪）
selenium.common.Exception.TimeoutException:消息：
屏幕截图：可通过屏幕

WebDriverWait方法实际上对我很有效：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC


driver = webdriver.PhantomJS()
driver.set_window_size(1120, 550)

driver.get("https://www.searchiqs.com/nybro/")

element = WebDriverWait(driver, 10).until(
            EC.presence_of_element_located((By.ID, "btnGuestLogin"))
        )
element.click()

没有错误。PhantomJS版本2.1.1、Selenium 2.53.6、Python 2.7

该问题可能与SSL和PhantomJS有关，或者通过

http

：

driver.get("http://www.searchiqs.com/nybro/")

或者，试试：

---

看看周围是否有任何框架…或者需要实现

WebDriverWait

以等待元素可见并可单击，而不是

时间。sleep

…）@SaurabhGaur，我已经进行了编辑，您可以使用新的备选脚本在文章底部看到它们。我仍然得到错误，那帧呢？？。。。确保

btnGuestLogin

不在任何框架或iframe@SaurabhGaur，它不在框架内。我检查了页面源，没有框架。@TendekaiMuchenje好的，打印页面源，你得到了什么

print（driver.page\u source）

。如果我在执行

driver.get（）

之后将其正确放置，它会打印出

，之后的任何位置都会导致error@TendekaiMuchenje好的，看你有空的页面来源。尝试添加

'--ssl protocol=any'

参数，并更新答案。我仍然得到相同的错误。我不知道为什么。我把“www.google.com”作为我的网站，它仍然给了我空页面的来源。它成功了！谢谢你的帮助！

driver.get("http://www.searchiqs.com/nybro/")

driver = webdriver.PhantomJS(service_args=['--ignore-ssl-errors=true', '--ssl-protocol=any'])
