使用Pyramid框架处理Web应用程序的POST请求

本示例展示了如何使用Pyramid框架处理Web应用程序的POST请求。该示例使用了formencode库来验证表单数据，并使用Python的built-in模块json将响应数据转换为JSON格式。此外，示例代码还展示了如何使用Response对象将响应发送回客户端。

from pyramid.view import (view_config, view_defaults)
from pyramid.response import Response
from formencode import Schema
from formencode.validators import (String, Int)
import json

class PostSchema(Schema):
    name = String(not_empty=True)
    age = Int(min=18)

@view_defaults(renderer='json')
class TestView:
    def __init__(self, request):
        self.request = request

    @view_config(route_name='test', request_method='POST', schema=PostSchema)
    def test_post(self):
        data = self.request.validated
        response = {'message': f"Hi {data['name']}, you are {data['age']} years old!"}
        return response

if __name__ == '__main__':
    from wsgiref.simple_server import make_server
    from pyramid.config import Configurator
    with Configurator() as config:
        config.add_route('test', '/test')
        config.scan()
        app = config.make_wsgi_app()
    server = make_server('localhost', 8080, app)
    server.serve_forever()
