如何使用硒执行网页上的所有JavaScript内容以在完全加载的网页上查找并发送登录表单信息 [英] How to execute all javascript content on webpage with selenium to find and send login form info on fully loaded webpage

问题描述

我一直试图制作一个Python脚本来登录某个网站，浏览菜单，填写表格并将其生成的文件保存到文件夹中.

I've been trying to make a Python script to login into a certain website, navigate through the menu, fill out a form and save the file it generates to a folder.

我一直在使用Selenium试图使网站完全加载，以便我可以找到登录元素，但是我没有成功，也许是因为网站在完全加载之前已经做了很多JavaScript内容，但是我无法使其完全加载并向我显示我想要的数据.

I've been using Selenium trying to make the website fully load so i can find the elements for the login, but i'm being unsucessful, maybe because the website does a lot of JavaScript content before it fully loads, but i can't make it fully load and show me the data i want.

我尝试了Robobrowser，Selenium，Requests和BeautifulSoup来完成它.

I tried Robobrowser, Selenium, Requests and BeautifulSoup to get it done.

import requests
from bs4 import BeautifulSoup
from selenium import webdriver

url = "https://directa.natal.rn.gov.br/"

driver = webdriver.Chrome(executable_path="C:\\webdrivers\\chromedriver.exe")
driver.get(url)

html = driver.execute_script("return document.documentElement.outerHTML")
sel_soup = BeautifulSoup(html, 'html.parser')

senha = driver.find_element_by_xpath('//*[@id="senha"]')
senha.send_keys("123")

我希望在密码(senha)字段中填写"123"，但我什至找不到该元素.

I expected to have filled the password (senha) field with "123" but i can't even find the element.

推荐答案

要将字符序列 123 发送到 password(senha)字段，作为所需的元素在<frame>之内，因此您必须:

To send the character sequence 123 to the password (senha) field, as the the desired elements are within a <frame> so you have to:

• 诱导 WebDriverWait 以使所需的框架可用并切换到.
• 诱导 WebDriverWait 以使所需的元素可点击.

• 您可以使用以下解决方案:

• Induce WebDriverWait for the desired frame to be available and switch to it.
• Induce WebDriverWait for the desired element to be clickable.

• You can use the following solution:

• 代码块:

• Code Block:

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

options = webdriver.ChromeOptions()
options.add_argument("start-maximized")
options.add_argument('disable-infobars')
options.add_argument("--disable-extensions")
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
driver.get("https://directa.natal.rn.gov.br/")
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"frame[name='mainsystem'][src^='main']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input.input[name='usuario']"))).send_keys("Tads")
driver.find_element_by_css_selector("input.input[name='senha']").send_keys("123")
