如何使用flsk和cosmosdb进行paggination

from flask import Flask, request
from azure.cosmos import CosmosClient

app = Flask(__name__)

endpoint = "your_cosmosdb_endpoint"
key = "your_cosmosdb_key"
database_name = "your_database_name"
container_name = "your_container_name"

client = CosmosClient(endpoint, key)
database = client.get_database_client(database_name)
container = database.get_container_client(container_name)

@app.route('/data', methods=['GET'])
def get_data():
    page_size = int(request.args.get('page_size', 10))
    continuation_token = request.args.get('continuation_token', None)

    query = "SELECT * FROM c OFFSET @offset LIMIT @limit"
    params = [
        {"name": "@offset", "value": continuation_token},
        {"name": "@limit", "value": page_size}
    ]

    result = container.query_items(
        query=query,
        parameters=params,
        enable_cross_partition_query=True
    )

    items = list(result)
    next_continuation_token = result.continuation_token

    return {
        "items": items,
        "continuation_token": next_continuation_token
    }

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