调用钉钉接口失败

Question

示例代码：

!/usr/bin/env python

import argparse
import logging
from dingtalk_stream import AckMessage
import dingtalk_stream

def setup_logger():
logger = logging.getLogger()
handler = logging.StreamHandler()
handler.setFormatter(
logging.Formatter(’%(asctime)s %(name)-8s %(levelname)-8s %(message)s [%(filename)s:%(lineno)d]’))
logger.addHandler(handler)
logger.setLevel(logging.INFO)
return logger

def define_options():
parser = argparse.ArgumentParser()
parser.add_argument(
’–client_id’, dest=‘client_id’, required=True,
help=‘app_key or suite_key from https://open-dev.digntalk.com’
)
parser.add_argument(
’–client_secret’, dest=‘client_secret’, required=True,
help=‘app_secret or suite_secret from https://open-dev.digntalk.com’
)
options = parser.parse_args()
return options

class EchoTextHandler(dingtalk_stream.ChatbotHandler):
def init(self, logger: logging.Logger = None):
super(dingtalk_stream.ChatbotHandler, self).init()
if logger:
self.logger = logger

async def process(self, callback: dingtalk_stream.CallbackMessage):
    incoming_message = dingtalk_stream.ChatbotMessage.from_dict(callback.data)
    print(incoming_message)
    text = incoming_message.text.content.strip()
    self.reply_text(text, incoming_message)
    return AckMessage.STATUS_OK, 'OK'

def main():
logger = setup_logger()
options = define_options()

credential = dingtalk_stream.Credential(options.client_id, options.client_secret)
client = dingtalk_stream.DingTalkStreamClient(credential)
client.register_callback_handler(dingtalk_stream.chatbot.ChatbotMessage.TOPIC, EchoTextHandler(logger))
client.start_forever()

if name == ‘main’:
main()

在macOS上，Python不会自动使用系统的证书存储。您需要安装证书：

1. 找到证书安装脚本： 在您的Python安装目录中找到Install Certificates.command文件，通常位于：

   /Library/Frameworks/Python.framework/Versions/3.12/bin/Install Certificates.command

2. 运行证书安装脚本：

   cd /Library/Frameworks/Python.framework/Versions/3.12/bin/
   ./Install\ Certificates.command

调不通可以拿钉钉官方SDK示例本地跑一下：https://github.com/open-dingtalk/dingtalk-stream-sdk-python?tab=readme-ov-file

  在本地全局环境下执行
  1. python3 -c "import certifi; print(certifi.where())"
  输出：/Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages/certifi/cacert.pem
  在项目下的poetry创建的虚拟环境中执行：
  1. poetry add certifi
  2. python -c "import certifi; print(certifi.where())"
  输出：/Users/imooc/Library/Caches/pypoetry/virtualenvs/dingtalk-langchain-G04N6Vrq-py3.12/lib/python3.12/site-packages/certifi/cacert.pem
  这说明我本地已经有证书了呀！
