如何使用Python填写JavaScript表单？

问题描述

我想使用Python填写this表单。

我尝试使用Mechanize，但这是一个使用JavaScript的Microsoft表单，没有表单标签，也没有GET / POST URL。也许BeautifulSoup / Selenium可以做到这一点，但是我在抓取JS表单方面没有任何经验。谁能帮助我，并提出解决方法的建议？

这是我尝试过的内容，Mechanize无法识别页面上的任何表格：

import mechanize

def main():
    br = mechanize.browser()
    br.set_handle_robots(False)
    br.set_handle_refresh(False)
    br.addheaders = [('User-agent','Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071615 Fedora/3.0.1-1.fc9 Firefox/3.0.1')]
    response  = br.open("https://forms.office.com/Pages/ResponsePage.aspx?id=8Pm7rtoj40mYvzIXGrvJvCxQDveyljlCrKN2Teo3EHFUQVNaWDlYRkhYR09JRTZWRFpKTTNIQU9HUC4u")
    for form in br.forms():
        print("Form name:",form.name) #prints nothing
        print(form) #prints nothing

if __name__ == '__main__':
    main()

解决方法

硒工作正常。

您需要install the components

• 安装硒pip install selenium
• 您需要确保为您的浏览器和操作系统版本下载正确的chromedriver（或其他驱动程序），并将其添加到路径

然后运行：

from selenium import webdriver

driver = webdriver.Chrome()
url = "https://forms.office.com/Pages/ResponsePage.aspx?id=8Pm7rtoj40mYvzIXGrvJvCxQDveyljlCrKN2Teo3EHFUQVNaWDlYRkhYR09JRTZWRFpKTTNIQU9HUC4u"
driver.get(url)


name = driver.find_element_by_xpath("//div[@class='question-title-box'][.//span[text()='NAME']]/following-sibling::*//input")
name.send_keys("hello,World")

setionSelection = "F"
section = driver.find_element_by_xpath("//div[@class='question-title-box'][.//span[text()='Section']]/following-sibling::*//input[@value='" + setionSelection + "']")
section.click()

date = driver.find_element_by_xpath("//input[contains(@placeholder,'Please input date')]")
date.send_keys("01/12/2020")


submit = driver.find_element_by_xpath("//div[text()='Submit']")
submit.click()

xapth有点长，但它们基于问题文本，因此可能很稳定

作为另一种方法-当您说没有POST网址时，是否检查过devtools？ -公开表单的目的地：

Request URL: https://forms.office.com/formapi/api/aebbf9f0-23da-49e3-98bf-32171abbc9bc/users/f70e502c-96b2-4239-aca3-764dea371071/forms('8Pm7rtoj40mYvzIXGrvJvCxQDveyljlCrKN2Teo3EHFUQVNaWDlYRkhYR09JRTZWRFpKTTNIQU9HUC4u')/responses
Request Method: POST

它也暴露了有效载荷...这是第一个提交：

{startDate: "2020-08-17T10:40:18.504Z",submitDate: "2020-08-17T10:40:18.507Z",…}
answers: "[{"questionId":"r8f09d63e6f6f42feb2f8f4f8ed3f9389","answer1":"Hello,World"},{"questionId":"r28fe12073dfa47399f8ce95ae679dccf","answer1":"G"},{"questionId":"r8f9e9fedcc2e410c80bfa1e0e3ef9750","answer1":"2020-08-28"}]"
startDate: "2020-08-17T10:40:18.504Z"
submitDate: "2020-08-17T10:40:18.507Z"

这些帖子URL UUID / GUID的问题ID对于此表单似乎很严格。每次我跑步时，他们都不会改变。这是第二次运行：

{startDate: "2020-08-17T10:43:48.544Z",submitDate: "2020-08-17T10:43:48.546Z","answer1":"test me"},"answer1":"2020-08-12"}]"
startDate: "2020-08-17T10:43:48.544Z"
submitDate: "2020-08-17T10:43:48.546Z"

一旦您捕获了此内容，您就可以通过不带GUI的API来完成此操作。

...只是为了确保，我尝试了一下，然后获得了成功...

import requests

url = "https://forms.office.com/formapi/api/aebbf9f0-23da-49e3-98bf-32171abbc9bc/users/f70e502c-96b2-4239-aca3-764dea371071/forms('8Pm7rtoj40mYvzIXGrvJvCxQDveyljlCrKN2Teo3EHFUQVNaWDlYRkhYR09JRTZWRFpKTTNIQU9HUC4u')/responses"
myobj = {"startDate":"2020-08-17T10:48:40.118Z","submitDate":"2020-08-17T10:48:40.121Z","answers":"[{\"questionId\":\"r8f09d63e6f6f42feb2f8f4f8ed3f9389\",\"answer1\":\"Hello again,World\"},{\"questionId\":\"r28fe12073dfa47399f8ce95ae679dccf\",\"answer1\":\"F\"},{\"questionId\":\"r8f9e9fedcc2e410c80bfa1e0e3ef9750\",\"answer1\":\"2020-08-26\"}]"}

x = requests.post(url,data = myobj)

我的答案只是硬编码到数据对象中，但似乎可行。

如果您还没有install requests，请记住点
