我们从Python开源项目中，提取了以下17个代码示例，用于说明如何使用tornado.web.Finish()。
def _handle_request_exception(self, e): if isinstance(e, Finish): # Not an error; just finish the request without logging. if not self._finished: self.finish(*e.args) return try: self.log_exception(*sys.exc_info()) except Exception: app_log.error("Error in exception logger", exc_info=True) if self._finished: return if isinstance(e, HTTPError): self.response(e) else: self.response(HTTPError(log_message=repr(e)))
def get(self): self.set_status(401) self.set_header('WWW-Authenticate', 'Basic realm="something"') if self.get_argument('finish_value', ''): raise Finish('authentication required') else: self.write('authentication required') raise Finish()
def emit(self, data): if type(data) is not str: serialized_data = json.dumps(data) else: serialized_data = data try: self.write('data: {}\n\n'.format(serialized_data)) await self.flush() except StreamClosedError: app_log.warning("Stream closed while handling %s", self.request.uri) # raise Finish to halt the handler raise web.Finish()
def get(self): self.set_status(401) self.set_header('WWW-Authenticate', 'Basic realm="something"') self.write('authentication required') raise Finish()
def cursor(self): cursor = self.get_argument('cursor', None) if cursor: try: cursor = int(cursor) except ValueError: self.redirect(self.request.path, permanent=True) raise Finish() if cursor < 0: raise HTTPError(404) else: cursor = None return cursor
def _handle_request_exception(self, e): from tornado.web import Finish, app_log, gen_log, HTTPError, httputil if isinstance(e, Finish): # Not an error; just finish the request without logging. if not self._finished: self.finish(*e.args) return ## add if isinstance(e, params.InvalidParams): self.set_status(400) self.finish({'error': str(e)}) return ## end try: self.log_exception(*sys.exc_info()) except Exception: # An error here should still get a best-effort send_error() # to avoid leaking the connection. app_log.error("Error in exception logger", exc_info=True) if self._finished: # Extra errors after the request has been finished should # be logged, but there is no reason to continue to try and # send a response. return if isinstance(e, HTTPError): if e.status_code not in httputil.responses and not e.reason: gen_log.error("Bad HTTP status code: %d", e.status_code) self.send_error(500, exc_info=sys.exc_info()) else: self.send_error(e.status_code, exc_info=sys.exc_info()) else: self.send_error(500, exc_info=sys.exc_info())
