如何从instagram messenger webhook获取instagram用户名

from flask import Flask, request, jsonify

app = Flask(__name__)

@app.route('/webhook', methods=['POST'])
def webhook():
    data = request.json
    sender_id = data['entry'][0]['messaging'][0]['sender']['id']
    # 这里你需要调用Instagram Graph API来获取用户名
    # 注意：你需要先申请Instagram Developer账号并创建应用以获取access_token
    access_token = 'YOUR_ACCESS_TOKEN'
    user_info_url = f'https://graph.instagram.com/{sender_id}?fields=id,username&access_token={access_token}'
    
    # 发送请求获取用户信息
    import requests
    response = requests.get(user_info_url)
    user_info = response.json()
    
    username = user_info.get('username', 'Unknown User')
    return jsonify({'username': username})

if __name__ == '__main__':
    app.run(port=5000)
