flask怎么开启多线程-创新互联
这篇文章主要讲解了flask怎么开启多线程,内容清晰明了,对此有兴趣的小伙伴可以学习一下,相信大家阅读完之后会有帮助。

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
if host is None:
host = '127.0.0.1'
if port is None:
server_name = self.config['SERVER_NAME']
if server_name and ':' in server_name:
port = int(server_name.rsplit(':', 1)[1])
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
# reset normally. This makes it possible to restart the server
# without reloader and that stuff from an interactive shell.
self._got_first_request = False 本文名称:flask怎么开启多线程-创新互联
