Teach you to build a nail warning robot hand in hand

Abstract

With the continuous increase of production and on-line business and the increasing demand for unattended , The emergence of nail warning robot has greatly solved our problem . This paper starts from 0 To 1 Introduce and explain in detail the construction and customization of the nail early warning robot , It is divided into robot construction , Early warning content development , Three steps for online deployment

Robot building

All the following configuration development comes from Nail official website documents , If you like to read the official website or have further personalized needs, you can go to check , You can also build it step by step from the perspective of junior developers with the essayist

The first is to have a group and you have the permission to add robots to this group , then

• Add robots

Group settings -- Intelligent group assistant -- Add robots -- Customize , Select Add , Then make the relevant settings

• Set up the robot

Start with a nice name , There are three security settings , There must be at least one

1. Custom keywords ： Customize the keywords of sending content , The content sent will only be sent if it contains the set keywords
2. The signature of the ： That is encryption , Generally, this one is used more ,
3. IP Address ： It's easy to understand , specific IP You can send content

Here we choose the second countersign , Then click Add , Here the group will prompt you that you have successfully added a robot

We open the robot and save the two data , Namely Webhook token And the countersigned ciphertext

https://oapi.dingtalk.com/robot/send?access_token=xxxxxxxxxxxWebhook: https://oapi.dingtalk.com/robot/send?access_token=xxxxxxxxxxx
The signature of the ：yyyyyyyyyyyyyyyyyyy

these two items. xxxxxx and yyyyy Keep it in reserve

Early warning content development

The above robots are added , Equivalent to a receiving data API The interface is ready , We are now developing early warning content

Use the simplest python, The overall framework code is as follows

from datetime import datetime, timedelta
import requests
import hmac
import hashlib
import base64
import urllib.parse
import urllib.request
import json
import time
import os
import sys
import re
def getUrl(secret,access_token):
    timestamp = str(round(time.time() * 1000))
    secret_enc = secret.encode('utf-8')
    string_to_sign = '{}\n{}'.format(timestamp, secret)
    string_to_sign_enc = string_to_sign.encode('utf-8')
    hmac_code = hmac.new(secret_enc, string_to_sign_enc, digestmod=hashlib.sha256).digest()
    sign = urllib.parse.quote_plus(base64.b64encode(hmac_code))
    url = "https://oapi.dingtalk.com/robot/send?access_token=%s&sign=%s&timestamp=%s" % (access_token, sign, timestamp)
    return url
def sendToGroup(url,header,data):
    sendData = json.dumps(data)# Convert dictionary type data to json Format 
    sendData = sendData.encode("utf-8") # python3 Of Request requirement data by byte type 
    request = urllib.request.Request(url=url, data=sendData, headers=header)
    opener = urllib.request.urlopen(request)
    return opener


secret= ''
access_token=''
data={
 "msgtype": "text",
 "text": {
     "content": " The analysis task has been completed "
 },
  "at": {
      "atMobiles": ["13216816870"],
      "isAtAll": False
  }
}

header = {
"Content-Type": "application/json",
"Charset": "UTF-8"
}
url=getUrl(secret,access_token)
opener=sendToGroup(url,header,data)

Put the above xxxx and yyyy Put it in the code secret and access_token, Can run , The nail robot will pop up

What the whole content needs to be developed is in the code data Which part

Our common query is through the database , So we also connect to the database to query , Add one more sql function code

def exeSqlRes(dbip,dbport,dbacco,dbpwd,dbname,sql):
    conn = connect(host=dbip, port=dbport, user=dbacco, password=dbpwd, database=dbname) 
    cursor = conn.cursor() 
    try:
        cursor.execute(sql)    
        list1 = cursor.fetchall()
        global dataStr1,dataStr2
        dataStr1 = " In line operation date  ：%s" % (list1[0][0])
        dataStr2 = " Public offering operation date  ：%s" % (list1[1][0])
    except:
        print(" Database connection failed \n")
    conn.close()
sql = '''
    SELECT SZ_TO_CHAR_D(max(d_date),'YYYYMMDD') as SYSTEMDATE from datacollect_log 
    union all 
    SELECT SZ_TO_CHAR_D(max(d_date),'YYYYMMDD') as SYSTEMDATE from datacollect_log 
    )
'''
exeSqlRes('xx.xx.xx.xx',3306,'xxxxx','xxxxx','xxxxx',sql)

data The official website of nailing introduces a lot , Yes txt,json,xml etc. , Limited to space , Here we only list the most commonly used MARKDOWN form

data = {
     "msgtype": "markdown",
     "markdown": {
         "title":" Data monitoring ",
         "text": "####  Current data run date  @17665011132 \n > - **%s** \n > - **%s** \n > ![screenshot](https://img-blog.csdnimg.cn/3c6a5aa682df459ab04d2fe5dc32475c.png?x-oss-process=image/watermark,type_d3F5LXplbmhlaQ,shadow_50,text_Q1NETiBA56We6Iq36L-m6JOd5a-6,size_20,color_FFFFFF,t_70,g_se,x_16)\n > ###### %s Release  [ Check the details ](https://www.dingtalk.com) \n" % (dataStr1,dataStr2,timeStr)
     },
      "at": {
          "atMobiles": [
              "176xxxx1132"
          ],
          "atUserIds": [
              ""
          ],
          "isAtAll": "false"
      }
 }

You can do it according to your actual needs data Development , After I finish the development here, the code pops up

  All configurations are completed

Online deployment

Put this python Put the code in crontab It can be scheduled to run on demand
