Question

我尝试从命令行启动Celery worker服务器：

celery -A server application worker --loglevel=info

代码和文件夹路径：

server.py  
application/controllers/routes.py

server.py

app = Flask(__name__)  
from application.controllers import routes  
app.run(host='127.0.0.1',port=5051,debug=True)

route.py

from flask import Flask,  
from celery import Celery
from server import app 


app.config['CELERY_BROKER_URL'] = 'redis://localhost:6379/0'
app.config['CELERY_RESULT_BACKEND'] = 'redis://localhost:6379/0' 

celery = Celery(app.name, broker=app.config['CELERY_BROKER_URL'])
celery.conf.update(app.config)

@celery.task()  
def add_together(self, count):  
   return "First success"

@app.route("/queing")  
def testsfunction():    
    count = 1  
    add_together.delay(count)  
    return "cool"

当我在码头经营芹菜工人时，我收到了这个错误。

Answer 1

用这个命令而不是你的命令运行芹菜：

celery -A application.controllers.routes:celery worker --loglevel=info

这将解决您当前的问题，但是您的代码有很多错误，例如，如果您想在add_together函数中设置自我参数，您应该声明这样的任务：

@celery.task(bind=True)

Answer 2

好像你有错误的错误：

def add_together(self, count):

到

def add_together(count):

烧瓶中的芹菜：AttributeError：'Flask'对象没有属性'user_options'
