我制作了一個倒數(shù)計時器，并在 for 循環(huán)中放置了 emit 函數(shù)。但是 emit 不會將我的計時器數(shù)據(jù)發(fā)送給客戶端。這是我的 python 服務(wù)器端代碼：from flask import Flask,render_template,render_template_stringfrom flask_socketio import SocketIO, emitapp = Flask(__name__) app.config['SECRET KEY'] = 'random'socketio = SocketIO(app)@app.route('/') def index(): return render_template('index.html')@socketio.on('test_timer')def Timer(seconds=3600): def hms(seconds): # hour minute second function h = seconds // 3600 m = seconds % 3600 // 60 s = seconds % 3600 % 60 return '{:02d}:{:02d}:{:02d}'.format(h, m, s) for i in range(seconds): emit(hms(seconds-i),broadcast=True) emit.sleep(1)if __name__ == '__main__': socketio.run(app,debug=True)這是我的客戶端 javascript 代碼：<!DOCTYPE html><html> <body> <script src="//cdnjs.cloudflare.com/ajax/libs/socket.io/2.2.0/socket.io.js" integrity="sha256-yr4fRk/GU1ehYJPAs8P4JlTgu0Hdsp4ZKrx8bDEDC3I=" crossorigin="anonymous"></script> <script type="text/javascript" charset="utf-8"> var socket = io().connect('http://127.0.0.1:5000'); socket.on('test_timer', function(receiving_data) { console.log(receiving_data); }); </script> </body></html>即使我運行服務(wù)器，console.log 也不會在客戶端打印任何計時器數(shù)據(jù)。
Python Flask emit() 函數(shù)不向客戶端發(fā)送實時數(shù)據(jù)
