如何从需要登录的url中获取图片？

import requests

# 发送登录请求获取会话
login_url = "https://example.com/login"
data = {"username": "your_username", "password": "your_password"}
response = requests.post(login_url, data=data)
session_cookie = response.cookies.get("session_cookie_name")

# 发送带有会话信息的请求获取图片
image_url = "https://example.com/image"
headers = {"Cookie": f"session_cookie_name={session_cookie}"}
response = requests.get(image_url, headers=headers)

# 保存图片到本地文件
with open("image.jpg", "wb") as file:
    file.write(response.content)

// 发送登录请求获取会话
const loginUrl = "https://example.com/login";
const data = { username: "your_username", password: "your_password" };
fetch(loginUrl, {
  method: "POST",
  body: JSON.stringify(data),
  headers: { "Content-Type": "application/json" },
})
  .then((response) => response.json())
  .then((data) => {
    const sessionCookie = data.session_cookie_name;

    // 发送带有会话信息的请求获取图片
    const imageUrl = "https://example.com/image";
    fetch(imageUrl, {
      headers: { Cookie: `session_cookie_name=${sessionCookie}` },
    })
      .then((response) => response.blob())
      .then((blob) => {
        // 处理图片数据
      });
  });
