【问题描述】：

分页不能与 AWS chalice 一起使用，还有其他方法可以实现分页吗？

from flask import request

@app.route('/hello/{name}')
def hello_name(name):
    page = request.args.get('page', 1, int)
    print(page)
#    # '/hello/james' -> {"hello": "james"}
    return {'hello': name}

错误：

Traceback (most recent call last):
  File "/Users/thirumal/opt/anaconda3/lib/python3.8/site-packages/chalice/app.py", line 1691, in _get_view_function_response
    response = view_function(**function_args)
  File "/Users/thirumal/git/vfc-lambda/app.py", line 39, in hello_name

    return self.__local()

This typically means that you attempted to use functionality that needed
an active HTTP request.  Consult the documentation on testing for
information about how to avoid this problem.

分页示例：-

from chalice import Chalice

app = Chalice(app_name='aws-chalice-tutorial')


@app.route('/pagination')
def pagination():
    app.log.debug("you are in Pagination!")
    return {
        'page': app.current_request.query_params.get('page'),
        'limit': app.current_request.query_params.get('limit'),
    }

请求：

http://localhost:8000/pagination?page=0&limit=10

{'page':'0','limit':'10'}
