如何在Falcon中将body发送到simulate_post

import falcon

app = falcon.App()

class MyResource:
    def on_post(self, req, resp):
        # 获取请求体内容
        body = req.stream.read()
        
        # 在这里可以对请求体进行处理或其他操作
        # ...
        
        # 返回响应
        resp.status = falcon.HTTP_200
        resp.body = 'Success'

app.add_route('/simulate_post', MyResource())

if __name__ == '__main__':
    from wsgiref import simple_server

    httpd = simple_server.make_server('localhost', 8000, app)
    httpd.serve_forever()
