如何在使用get方法而不使用post方法的网站中使用python登录？

import requests
from bs4 import BeautifulSoup

# 发送GET请求，获取登录页面的HTML内容
login_url = "http://example.com/login"
response = requests.get(login_url)
html_content = response.text

# 解析登录页面，找到登录表单的相关信息
soup = BeautifulSoup(html_content, "html.parser")
form = soup.find("form")
action_url = form["action"]
username_field = form.find("input", {"name": "username"})["name"]
password_field = form.find("input", {"name": "password"})["name"]

# 构造登录数据
login_data = {
    username_field: "your_username",
    password_field: "your_password"
}

# 发送POST请求，进行登录
response = requests.post(action_url, data=login_data)

# 验证登录结果
if "登录成功" in response.text:
    print("登录成功")
else:
    print("登录失败")
