Click Finish to generate a Webhook Address , This address and key should not be published casually , There will be security risks if it is placed on an external website .

Get signature value

We have obtained the key and Webhook, First, parse the key to get the timestamp (timestamp) And signature value (sign), The code is as follows .

import time
import hmac
import hashlib
import base64
import urllib.parse
timestamp = str(round(time.time() * 1000))
secret = ' Fill in your key '
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))
print(timestamp)
print(sign)

timestamp,sign As two key parameters , Match them with Webhook Splicing .

import time
import hmac
import hashlib
import base64
import urllib.parse
import datetime
import json
timestamp = str(round(time.time() * 1000))
secret = ' Fill in your key '
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))
print(timestamp)
print(sign)
url = f'https://oapi.dingtalk.com/robot/send?access_token=xxxx&timestamp={
timestamp}&sign={
sign}'
def send_request(url, datas):
header = {

"Content-Type": "application/json",
"Charset": "UTF-8"
}
sendData = json.dumps(datas)
sendDatas = sendData.encode("utf-8")
request = urllib.request.Request(url=url, data=sendDatas, headers=header)
opener = urllib.request.urlopen(request)
# Output response results 
print(opener.read())
def get_string():
''' What you want to send , Notice the message format , If you choose markdown, Expected to contain... In string Markdown Content of format example ： "<font color=#00ffff> Yesterday's sales ：XXX</font> \n <font color=#00ffff> Yesterday's sales ：XXX</font>" '''
