flask 后台程序执行方法

由于flask后台多线程、多进程都是假的，所以想异步操作必须多一些代码内容。解决方法主要是2种：

一、使用Celery (http://www.celeryproject.org/),或者RQ (http://python-rq.org/).实现异步分布式后台操作。

二、简单的使用python代码了：

# -*- coding: utf8 -*-from flask import Flaskfrom time import sleepfrom concurrent.futures import ThreadPoolExecutor# DOCS https://docs.python.org/3/library/concurrent.futures.html#concurrent.futures.ThreadPoolExecutorexecutor = ThreadPoolExecutor(1)app = Flask(__name__)@app.route('/jobs')def run_jobs():    executor.submit(some_long_task1)    executor.submit(some_long_task2, 'hello', 123)    return 'Two jobs was launched in background!'def some_long_task1():    print("Task #1 started!")    sleep(10)    print("Task #1 is done!")def some_long_task2(arg1, arg2):    print("Task #2 started with args: %s %s!" % (arg1, arg2))    sleep(5)    print("Task #2 is done!")if __name__ == '__main__':    app.run()    app.run("0.0.0.0", 888, debug=True)
