我一直在使用Flask,Python和Flask-Socket.io库开发应用程序.我emit遇到的问题是由于某些上下文问题,以下代码将无法正确执行
RuntimeError: working outside of request context
我现在只为整个程序编写一个python文件.这是我的代码(test.py):
from threading import Thread
from flask import Flask, render_template, session, request, jsonify, current_app, copy_current_request_context
from flask.ext.socketio import *
app = Flask(__name__)
app.debug = True
app.config['SECRET_KEY'] = 'secret!'
socketio = SocketIO(app)
def somefunction():
# some tasks
someotherfunction()
def someotherfunction():
# some other tasks
emit('anEvent', jsondata, namespace='/test') # here occurs the error
@socketio.on('connect', namespace='/test')
def setupconnect():
global someThread
someThread = Thread(target=somefunction)
someThread.daemon = True …我有一个使用Flask和FlaskSocket.IO 2.8.4的应用程序。当我初始化SocketIO时，我正在使用
#[...]
logging.basicConfig(level=logging.DEBUG,format='[%(asctime)s][%(levelname)s] - %(funcName)s: %(message)s')
logger = logging.getLogger(__name__)
handler = logging.FileHandler(__builtin__.config['dir']['log_file_handler'])
handler.setLevel(logging.DEBUG)
formatter = logging.Formatter('[%(asctime)s][%(levelname)s] - %(funcName)s: %(message)s')
handler.setFormatter(formatter)
logger.addHandler(handler)
# Setting up flask external plugins
socketio = SocketIO(app, logger = False)
#[...]
if __name__ == '__main__':
socketio.run(app, port=8000)
无论如何，我的日志中的输出有很多emit，receive和以下handle_event行：
[2017-04-19 05:17:02,172][INFO] - receive: 1139f764dbe64a1ba6e1c8d95228400c: Received packet MESSAGE data 2/telescope,["AskForTimeEvent"]
