celery结合发布

views.py

代码

from \_\_future\_\_ import absolute\_import, unicode\_literals

import time

import requests

from celery import shared_task

from django.views.decorators.csrf import csrf\_exempt,csrf\_protect

from django.shortcuts import render,HttpResponse,redirect

@shared_task

def add(x,y):

    return x+y

@shared_task

def salt(app\_name,host\_li,package):

    # 第一步  :在 自动化管理平台  里面 下载代码 (可以打包)   subporcsess

    # import os

    # import sys

    # path = os.getcwd() + r'/project_path/'

    # subporcsess -->执行命令 cd  path

    # mkdir $app\_name && cd $app\_name

    # svn co $package

    # 打包

    # 第二步  :推送  -->salt stack   state.sls

    # 写 state.sls 规则的yml 文件

    # 通过python 代码  salt api  调用  state 触发 推送

    # 第三步   #执行远端代码   -->cmd.run      cd  路径  python xxx

    return True

@shared_task

def mul(x, y):

    print(x*y)

    return x * y

@shared_task

def xsum(numbers):

    print(sum(numbers))

    return sum(numbers)

带坑的发布串行

views.py

代码

from django.shortcuts import render,HttpResponse,redirect

from django.views import View

from demo1 import models

from demo1.task import add

from celery.result import AsyncResult

        app=request.POST.get('app')

        obj\_li = models.App.objects.filter(name=app,environment\_\_name=env)

        #拿到 对应的 主机组             代码-->地址

        #循环 主机组    推送代码

        app_name = 'payment'

        host_li = \[{'id':'test','path':'/app/www/payment'},\]

        package = 'svn://xxxxx'  #sh xxxx.sh                     #改成自己的地址

        return HttpResponse('已存入队列中')

def celery_status(req):

    import datetime

    import json

    if req.method=='GET':

        if req.GET.get('x') and req.GET.get('y'):

            # ret=add.delay(int(req.GET.get('x')),int(req.GET.get('y')))

            if req.GET.get('after'):

                utc_ctime = datetime.datetime.utcfromtimestamp(ctime.timestamp())

                s1 = datetime.timedelta(seconds=int(req.GET.get('after'))*60)

                ctime\_x = utc\_ctime + s1

                # 使用apply_async并设定时间

            year=req.GET.get('year')

            mouth=req.GET.get('month')

            day=req.GET.get('day')

            hour=req.GET.get('hour')

            minute=req.GET.get('minute')

            if year and mouth and day and hour and minute:

                ctime = datetime.datetime(year=int(year), month=int(mouth),

                ret = add.apply\_async(args=\[int(req.GET.get('x')), int(req.GET.get('y'))\], eta=ctime\_x)

                num=ret.id

        if req.GET.get('cancel'):

            async = AsyncResult(id=req.GET.get('cancel'), app=app)

            async.revoke(terminate=True)

            cancel_tag='取消成功'

        if req.GET.get('stop'):

            async = AsyncResult(id=req.GET.get('stop'), app=app)

            async.revoke()

            stop_tag='中止成功'

        return render(req,'celery.html',locals())

    else:

        ret=req.POST.get('id','')

        data = ''

        if ret:

            async=AsyncResult(id=ret,app=app)

            if async.successful():

                async.forget()

            elif async.failed():
