Question

我想知道在阅读页面源后是否有一种POST参数的方法。例如：在发布ID＃

之前阅读验证码

我目前的代码：

import requests
id_number = "1"
url = "http://www.submitmyforum.com/page.php"
data = dict(id = id_number, name = 'Alex')
post = requests.post(url, data=data)

每次请求http://submitforum.com/page.php后都可以更改验证码（不是真实网站）我想读取该参数并将其提交给＆＃34;数据＆＃34;变量

正如OP评论中所讨论的，可以使用selenium，也可以存在没有浏览器仿真的方法！

使用Selenium（http://selenium-python.readthedocs.io/）代替请求模块方法：

import re
import selenium
from selenium import webdriver

regexCaptcha = "k=.*&co="
url = "http://submitforum.com/page.php"

# Get to the URL
browser = webdriver.Chrome()
browser.get(url)

# Example for getting page elements (using css seletors)
# In this example, I'm getting the google recaptcha ID if present on the current page
try:
    element = browser.find_element_by_css_selector('iframe[src*="https://www.google.com/recaptcha/api2/anchor?k"]')
    captchaID = re.findall(regexCaptcha, element.get_attribute("src"))[0].replace("k=", "").replace("&co=", "")
    captchaFound = True
    print "Captcha found !", captchaID
except Exception, ex:
    print "No captcha found !"
    captchaFound = False

# Treat captcha
# --> Your treatment code

# Enter Captcha Response on page
captchResponse = browser.find_element_by_id('captcha-response')
captchResponse.send_keys(captcha_answer)

# Validate the form
validateButton = browser.find_element_by_id('submitButton')
validateButton.click()

# --> Analysis of returned page if needed
