我们从Python开源项目中，提取了以下6个代码示例，用于说明如何使用botocore.exceptions.ConnectionClosedError()。
def _get_response(self, request, operation_model, attempts): # This will return a tuple of (success_response, exception) # and success_response is itself a tuple of # (http_response, parsed_dict). # If an exception occurs then the success_response is None. # If no exception occurs then exception is None. try: logger.debug("Sending http request: %s", request) http_response = self.http_session.send( request, verify=self.verify, stream=operation_model.has_streaming_output, proxies=self.proxies, timeout=self.timeout) except ConnectionError as e: # For a connection error, if it looks like it's a DNS # lookup issue, 99% of the time this is due to a misconfigured # region/endpoint so we'll raise a more specific error message # to help users. logger.debug("ConnectionError received when sending HTTP request.", exc_info=True) if self._looks_like_dns_error(e): endpoint_url = e.request.url better_exception = EndpointConnectionError( endpoint_url=endpoint_url, error=e) return (None, better_exception) elif self._looks_like_bad_status_line(e): better_exception = ConnectionClosedError( endpoint_url=e.request.url, request=e.request) return (None, better_exception) else: return (None, e) except Exception as e: logger.debug("Exception received when sending HTTP request.", exc_info=True) return (None, e) # This returns the http_response and the parsed_data. response_dict = convert_to_response_dict(http_response, operation_model) parser = self._response_parser_factory.create_parser( operation_model.metadata['protocol']) parsed_response = parser.parse( response_dict, operation_model.output_shape) return (http_response, parsed_response), None
