celery：错误：无法识别的参数：-A，Flask，argparse

Question

在基于Flask的Web应用程序中，使用arg文件中的两个命令行参数ini filename，端口号，在同一个文件芹菜应用程序中也定义了。但是在运行芹菜应用程序时我得到了上述错误。

<div class="uk-width-1-4 start-time-div">
                                        <label class="uk-form-label uk-display-block">Start Time</label>
                                        <div class="uk-form-controls uk-clearfix">
                                            <div class="yn_formdatewrap">
                                                <div class="uk-form-icon uk-form-icon-flip uk-width-1-1">
                                                    <i class="yash_icons yash-ion-android-time"></i>
                                                    <input type="text" name="start_time[]" placeholder="Start Time" data-uk-timepicker="{format:'12h'}" 
                                                    class="uk-width-1-1 yn_formcommon yn_formtext timing-req start_time">
                                                </div>
                                            </div>
                                        </div>
                                    </div>

                                    <div class="uk-width-1-4 end-time-div">
                                        <label class="uk-form-label uk-display-block">End Time</label>
                                        <div class="uk-form-controls uk-clearfix">
                                            <div class="yn_formdatewrap">
                                                <div class="uk-form-icon uk-form-icon-flip uk-width-1-1">
                                                    <i class="yash_icons yash-ion-android-time"></i>
                                                    <input type="text" name="end_time[]" placeholder="End Time" data-uk-timepicker="{format:'12h'}" 
                                                    class="uk-width-1-1 yn_formcommon yn_formtext timing-req end_time">
                                                </div>
                                            </div>
                                        </div>
                                    </div>

------- CELERY CONFIGS -------

import argparse
from flask import  Flask
from celery import Celery

app = Flask(__name__)
parser = argparse.ArgumentParser(prog="testpgm")
parser.add_argument('-c','--cfgfile', default='domain.ini', help="provide ini      file path")
parser.add_argument('-p','--port', default=5000, help="-p port number eg - 'python run.py -p <port>, default to 5000")
args = parser.parse_args()
ini_path = args.cfgfile
port = args.port

但是当我使用

运行芹菜时

app.config["CELERY_QUEUES"] = (
Queue('queue1', Exchange('queue1'), routing_key='queue1')
)
def make_celery(flaskapp):

   #getting celery broker uri
   celery_broker_uri=         CeleryBrokerWrapper().get_broker_uri(broker,username,password,host,port,vhost) 

   celeryinit = Celery(flaskapp.import_name, broker=celery_broker_uri)
   celeryinit.conf.update(flaskapp.config)
   taskbase = celeryinit.Task

   class ContextTask(taskbase):
      abstract = True

      def __call__(self, *args, **kwargs):
         with app.app_context():
             return taskbase.__call__(self, *args, **kwargs)

   celeryinit.Task = ContextTask
   return celeryinit

celery = make_celery(app)

我收到错误

celery -A testpgm.celery worker --loglevel=info --concurrency=5 -Q queue1

它看起来像一个argparse错误，如何为我的应用程序自定义argparse，而没有芹菜的命令行参数问题..

Answer 1

你需要重新订购args：

celery worker -A testpgm.celery --loglevel=info --concurrency=5 -Q queue1

Answer 2

有一个类似的问题，argparse也抱怨我。

快速修复：使用parse_known_args，而不是parse_args

args, unknown = parser.parse_known_args()

源： Python argparse ignore unrecognised arguments

丑陋的修复： 定义芹菜工人args作为你的主应用程序的argparse的一部分

“做得对”修复： 考虑在主函数中使用argparse，以便芹菜不会与它发生冲突
