如何使用python登录网站，点击按钮获取源码

pip install requests beautifulsoup4

import requests

url = "https://example.com/login"
data = {
    "username": "user@example.com",
    "password": "password123"
}
response = requests.post(url, data=data)

from bs4 import BeautifulSoup

soup = BeautifulSoup(response.text, "html.parser")
button = soup.find("button", {"id": "button-id"})
button_source_code = button.get_text()

import requests
from bs4 import BeautifulSoup

def login_and_get_source_code(login_url, username, password, button_id):
    # 发送登录请求
    login_data = {
        "username": username,
        "password": password
    }
    response = requests.post(login_url, data=login_data)

    # 解析登录后的页面
    soup = BeautifulSoup(response.text, "html.parser")
    button = soup.find("button", {"id": button_id})
    button_source_code = button.get_text()

    return button_source_code

# 使用示例
login_url = "https://example.com/login"
username = "user@example.com"
password = "password123"
button_id = "button-id"
source_code = login_and_get_source_code(login_url, username, password, button_id)
print(source_code)
