使用selenium webdriver python使用xpath登录到jsp表单

Question

I'm trying to login in to a jsp form with selenium webdriver in python.我正在尝试使用 python 中的 selenium webdriver 登录到 jsp 表单。 I'm trying to login by posting the parameters but I cannot reach the form or anything beyond the body tag for that matter.我正在尝试通过发布参数登录，但我无法访问表单或正文标签之外的任何内容。 What am i doing wrong?我究竟做错了什么？ Below is my code and below that is the page source - since it is a non-public web page:下面是我的代码，下面是页面源代码 - 因为它是一个非公开网页：

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

def my_method():
    driver = webdriver.PhantomJS()
    driver.get("https://<URL>.se:20443/snl/login.jsp")

    password = driver.find_element_by_xpath("//input[@id='j_password']")

    driver.close()

my_method()

Answer 1

I think you need towait for the page to load or, to be more specific, wait for the visibility of the password field :我认为您需要等待页面加载，或者更具体地说，等待密码字段的可见性：

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

wait = WebDriverWait(driver, 10)
password = wait.until(EC.visibility_of_element_located((By.ID, "j_password")))
password.send_keys("password")

Answer 2

I solved the problem by passing a service argument to ignore ssl errors ( service_args=['--ignore-ssl-errors=true'] ) like this:我通过传递一个服务参数来忽略 ssl 错误（ service_args=['--ignore-ssl-errors=true'] ）解决了这个问题，如下所示：

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

Then it worked!然后它起作用了！
