在firestore中设置python http函数

import firebase_admin
from firebase_admin import credentials
from firebase_admin import firestore

# 初始化Firebase Admin SDK
cred = credentials.Certificate('path/to/serviceAccountKey.json')
firebase_admin.initialize_app(cred)

# 获取Firestore数据库实例
db = firestore.client()

# 设置HTTP函数
def set_data(request):
    # 从HTTP请求中获取数据
    data = request.get_json()
    
    # 将数据写入Firestore数据库
    doc_ref = db.collection('collection_name').document('document_id')
    doc_ref.set(data)
    
    # 返回成功响应
    return 'Data set successfully.'

# 接收HTTP请求并调用函数
def main(request):
    if request.method == 'POST':
        return set_data(request)
    else:
        return 'Invalid request method.'
