crew 0.9.2

使用量

例如，创建第一个应用程序，并另存为master.py:

import tornado.ioloop
import tornado.gen
import tornado.web
import tornado.log
import json
import tornado.options
from crew import TimeoutError, ExpirationError
from crew.master.tornado import Client

class MainHandler(tornado.web.RequestHandler):

    @tornado.gen.coroutine
    def get(self):
        resp = yield self.settings['crew'].call(None, priority=100)
        self.write(json.dumps(resp))

cl = Client()
application = tornado.web.Application(
    [
        (r"/", MainHandler),
    ],
    crew=cl,
    autoreload=True,
    debug=True,
)

if __name__ == "__main__":
    cl.connect()
    tornado.options.parse_command_line()
    application.listen(8888)
    tornado.ioloop.IOLoop.instance().start()

然后创建第一个任务，并另存为worker.py:

# encoding: utf-8
from crew.worker import run, context, Task

@Task('test')
def long_task(req):
    context.settings.counter += 1
    return {"counter": context.settings.counter}

run(
    counter=0
)

之后运行：

$ python master.py &
$ python worker.py &
$ wait

尝试测试：

$ curl http://localhost:8888/
