python向企业微信发送文字和图片消息的示例

吐槽一下企业微信的api文档真的不好读······

企业微信本来是有功能，可以直接把图片显示到正文的，但是那个api我调用一直出错，各种折腾也没解决。后来感觉就算了，没必要，用url拼接在文字中也行，这样的好处就是以后可以换图床，不局限在企业微信内部(好像免费版一天之内可以上传200张图片，所以如果需求比较大的话可以采用第三方图床)

我把上传部分封装了一个使用新线程的方法，以防使用的时候因为上传卡住主线程(亲测如果不这样的话确实会卡住)

import requests
import json
from threading import Thread
import cv2
import os


class Wechat_Info():
  def __init__(self):
    self.partyID = \'\'
    self.corpID = \'\'
    self.secret = \'\'
    self.agentID = \'\'
    self.token = None
    self.pic = None

  def __get_token(self, corpid, secret):
    Url = \"https://qyapi.weixin.qq.com/cgi-bin/gettoken\"
    Data = {
      \"corpid\": corpid,
      \"corpsecret\": secret
    }
    r = requests.get(url=Url, params=Data)
    token = r.json()[\'access_token\']
    return token

  def send_message(self, message):
    url = \"https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token={}\".format(
      self.__get_token(self.corpID, self.secret))
    data = {
      \"toparty\": self.partyID,
      \"msgtype\": \"text\",
      \"agentid\": self.agentID,
      \"text\": {
        \"content\": message
      },
      \"safe\": \"0\"
    }
    result = requests.post(url=url, data=json.dumps(data))
    return result.text

  def get_media_url(self, path): ##上传到图片素材 图片url
    Gtoken = self.__get_token(self.corpID, self.secret)
    img_url = \"https://qyapi.weixin.qq.com/cgi-bin/media/uploadimg?access_token={}\".format(Gtoken)
    files = {\'media\': open(path, \'rb\')}
    r = requests.post(img_url, files=files)
    re = json.loads(r.text)
    # print(\"media_id: \" + re[\'media_id\'])
    return re[\'url\']

  def send_pic(self, pic_path):
    img_url = self.get_media_url(pic_path)
    url = \"https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token={}\".format(
      self.__get_token(self.corpID, self.secret))
    data = {
      \"toparty\": self.partyID,
      \"msgtype\": \"text\",
      \"agentid\": self.agentID,
      \"text\": {
        \"content\": img_url
      },
      \"safe\": \"0\"
    }
    result = requests.post(url=url, data=json.dumps(data))
    return result.text

  def send_violence_warning(self, pic_path):
    img_url = self.get_media_url(pic_path)
    url = \"https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token={}\".format(
      self.__get_token(self.corpID, self.secret))
    data = {
      \"toparty\": self.partyID,
      \"msgtype\": \"text\",
      \"agentid\": self.agentID,
      \"text\": {
        \"content\": \'【管理员注意】，有校园暴力行为发生，请及时处理！监控图片>>\' + img_url
      },
      \"safe\": \"0\"
    }
    result = requests.post(url=url, data=json.dumps(data))
    return result.text

  def send_violence_warning_read_path_from_class(self):
    pic_path = \'temp.jpg\'
    cv2.imwrite(pic_path, self.pic)
    self.send_violence_warning(pic_path)
    os.remove(pic_path)

  def send_violence_warning_in_new_thread(self, pic):
    self.pic = pic
    thread = Thread(target=self.send_violence_warning_read_path_from_class)
    thread.start()



if __name__ == \'__main__\':
  wechat_info = Wechat_Info()
  # result = wechat_info.send_message(\'微信测试_2020\')
  # result = wechat_info.send_pic(\'C:\\\\Users\\\\JiaDing\\\\Desktop\\\\pic.jpg\')
  result = wechat_info.send_violence_warning(\'C:\\\\Users\\\\JiaDing\\\\Desktop\\\\pic.jpg\')
  print(result)

在主线程里面调用那个send_violence_warning_in_new_thread，把opencv的图片传进来就行

效果：
