    application = Application([Test], 'spyne.examples.hello.http',

                            in_protocol=HttpRpc(validator='soft'),

                            out_protocol=JsonDocument(ignore_wrappers=True),
                            )

    wsgi_application = WsgiApplication(application)

    server = make_server('0.0.0.0', 22346, wsgi_application)

    logging.info("listening to http://127.0.0.1:22346")
    logging.info("wsdl is at: http://localhost:22346/?wsdl")

    server.serve_forever()

我试图建立一个Web服务，用户通过该服务提供一块python代码，然后该服务反馈一些信息，但是python函数exec似乎在spyne中不起作用。我通过127.0.0.1:22346/Test?execcodes='a=1\nb=2\nprint(a+b)\n'触发了函数execcodes，关于exec的错误没有出现，但是在日志记录中没有打印，并且我在本地变量和全局变量中都找不到a和b，所以我很困惑我的代码是否已执行？如果执行了，我在哪里可以找到变量？

python exec函数在spyne模块中不起作用
