示例1: WSHandler
# 需要导入模块: from rx.subjects import Subject [as 别名]
# 或者: from rx.subjects.Subject import select [as 别名]
class WSHandler(WebSocketHandler):
def open(self):
print("WebSocket opened")
# A Subject is both an observable and observer, so we can both subscribe
# to it and also feed (on_next) it with new values
self.subject = Subject()
# Get all distinct key up events from the input and only fire if long enough and distinct
query = self.subject.select(
lambda x: x["term"]
).filter(
lambda text: len(text) > 2 # Only if the text is longer than 2 characters
).throttle(
0.750, # Pause for 750ms
scheduler=scheduler
).distinct_until_changed() # Only if the value has changed
searcher = query.flat_map_latest(search_wikipedia)
def send_response(x):
self.write_message(x.body)
def on_error(ex):
print(ex)
searcher.subscribe(send_response, on_error)
def on_message(self, message):
obj = json_decode(message)
self.subject.on_next(obj)
def on_close(self):
