我真的很喜欢Python selenium模块

Question

我正在做一个简单的程序，使我能够填写登录表单和发送电子邮件给某人…当我在上面的时候，它只是不去更多，停止打开一些链接。

# Practice Program!

import requests, os, bs4, webbrowser
from selenium import webdriver

url = 'http://google.com'

res = requests.get(url)
res.raise_for_status()

browser = webdriver.Firefox()

browser.get(url)

signinElem = browser.find_element_by_id('gb_70')
signinElem.click()

idElem = browser.find_element_by_id('Email')
idElem.send_keys('not_my_real_id')
idElem.submit()

pwElem = browser.find_element_by_id('Passwd')
pwElem.send_keys('not_my_pw')
pwElem.submit()

mailElem = browser.find_element_by_class_name('gb_P')
mailElem.click()

composeElem = browser.find_element_by_class_name('class="T-I J-J5-Ji T-I-KE L3')
composeElem.click()

我有以下错误

回溯（最近的调用为last）：文件“C://users/cyber/downloads/writemail.py”，第22行，在pwElem=browser.find_element_by_id('passwd')中文件“C:\users\cyber\downloads\lib\site-packages\selenium\webdriver\remote\webdriver.py”，第269行，在find_element_by_id返回self.find_element(by=by.id,value=id)文件“downloads\lib\site-packages\selenium\webdriver\remote\webdriver.py”，第236行，执行self.error_handler.check_response（响应）文件“C:\users\cyber\downloads\lib\site-packages\selenium\webdriver\remote\errorhandler.py”，第192行，在check_response引发exception_class（消息，屏幕，stacktrace）驱动程序@googlecode.cOM/components/driver-component.js:10770)在（文件：///C：/users/cyber/appdata/local/temp/tmpczr__hhf/extensions/[e-mail]/components/driver-component.js:10779)在（文件：///C：/users/cyber/appdata/local/temp/tmpczr__hhf/extensions/[e-mail]/components/fxdriver-processor.js:12666)at（文件：///c://users/cyber/appdata/local/temp/tmpczr__hhf/extensions/[e-mail]/components/command-processor.js:12608)

Answer 1

当您提交电子邮件时，Paasword字段可见，因此您需要实现WebDriverWait，直到Password字段可见，如下所示：-

from selenium.webdriver.support import expected_conditions as EC

-------------

wait = WebDriverWait(browser, 10)

idElem = wait.until(EC.visibility_of_element_located((By.ID, "Email")))
idElem.send_keys('not_my_real_id')
idElem.submit()


pwElem = wait.until(EC.visibility_of_element_located((By.ID, "Passwd")))
pwElem.send_keys('not_my_pw')
pwElem.submit()

希望对你有帮助…：）
