flask开启多线程的具体方法

flask开启多线程的具体方法开启多线程的具体方法

在本篇内容里小编给大家整理的是一篇关于flask开启多线程的具体方法，对此有需求的可以学习参考下。

在我之前解释了flask如何支持多线程主要通过两个类来实现,LocalStack和Local,在Local中有两个属性,__storage__和

__ident_func__,后者用来获取线程id,从而区分不同线程发来的请求

这次要说的是flask如何开启多线程

先从app.run()这个方法看起

def run(self, host=None, port=None, debug=None, **options):

from werkzeug.serving import run_simple

else:

port = 5000

if debug is not None:

self.debug = bool(debug)

options.setdefault('use_reloader', self.debug)

options.setdefault('use_debugger', self.debug)

try:

run_simple(host, port, self, **options) #会进入这个函数

finally:

# reset the first request information if the development server

extra_files=None, reloader_interval=1,

reloader_type='auto', threaded=False,

processes=1, request_handler=None, static_files=None,

passthrough_errors=False, ssl_context=None):

"""Start a WSGI application. Optional features include a reloader,

multithreading and fork support.

This function has a command-line interface too::

python -m werkzeug.serving --help

support for SSL was added.

.. versionadded:: 0.8

Added support for automatically loading a SSL context from certificate

file and private key.

.. versionadded:: 0.9

Added command-line interface.

.. versionadded:: 0.10

:param application: the WSGI application to execute

:param use_reloader: should the server automatically restart the python

process if modules were changed?

:param use_debugger: should the werkzeug debugging system be used?

:param use_evalex: should the exception evaluation feature be enabled?

:param extra_files: a list of files the reloader should watch

additionally to the modules. For example configuration

files.
