python - 使用内置 Python 模块填写 Web 表单数据

Question

好吧，我在冒险中使用了 mechanize、requests、beautiful soup，甚至 selenium 来做这样的事情，我得出的结论是 urllib 和其他默认模块是最好的方法。唯一的问题是我根本不知道如何使用它。所以有人可以告诉我一些专门了解它的好地方吗？此外，我通过示例学习得最好，所以如果有人将其转换为我要求的内容，那就太好了(还包括提交按钮哈哈)

from selenium import webdriver

driver = webdriver.Firefox()

driver.get("http://www.jonessoda.com/contests/back2school")
element = driver.find_element_by_name("fname")
element.send_keys("Ben")

Answer 1

您确实需要 Selenium。它模拟浏览器上的 GUI 交互。 在执行诸如输入比赛表格数据之类的操作时，这将是最不容易被发现的方式。

A note about selenium: It is not a language-specific library. There are client specific bindings for each language. Most examples and how-to's you'll see are actually written in Java.

一个很好的资源是Selenium-python

这是您的工作示例。包括提交按钮。

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
i = 2 # do it 2 times
while i > 0:
    driver = webdriver.Firefox()
    driver.get("http://www.jonessoda.com/contests/back2school")

    def find_by_xpath(locator):
        element = WebDriverWait(driver, 10).until(
            EC.presence_of_element_located((By.XPATH, locator))
        )

        return element

    class FormPage(object):
        def fill_form(self, data):
            find_by_xpath('//input[@name = "fname"]').send_keys(data['fname'])
            find_by_xpath('//input[@name = "lname"]').send_keys(data['lname'])
            find_by_xpath('//input[@name = "email"]').send_keys(data['email'])
            find_by_xpath('//select[@name = "birthday_month"]').send_keys(data['month'])
            find_by_xpath('//select[@name = "birthday_day"]').send_keys(data['day'])
            find_by_xpath('//select[@name = "birthday_year"]').send_keys(data['year'])

            return self # makes it so you can call .submit() after calling this function

        def submit(self):
            find_by_xpath('//input[@value = "Submit"]').click()

    data = {
        'fname': 'Sheep',
        'lname': 'Test',
        'email': 'jess@sheeptest.com',
        'month': 'October',
        'day': '29',
        'year': '1920'
    }

    FormPage().fill_form(data).submit()
    driver.quit() # closes the webbrowser
    i = i - 1
