我们目前在套接字连接错误方面遇到一些困难。我们的微服务在Flask中运行，带有Flask-SocketIO软件包。
当前有三个API-全部使用Python： -1-带有服务器的Socket Flask API -2-具有端点的Flask API，用于设置socketio客户端 -3-要求上述API的聊天机器人
考虑到第二个API的狂热，可以与第一个API建立成功的连接。一切按预期进行：客户端连接并进入房间。
但是，当以另一个API（例如第三个API）间接发出python请求时，会出现以下错误：
文件“”，第3行，在raise_from中 api_kpi | socketio.exceptions.ConnectionError：服务器拒绝连接
有人知道可能发生的事情吗？我们还尝试过其他后端（例如Node），并且连接有效。
非常感谢！
发出请求的函数-出现以下错误：
def make_request_api（自己）： '''Faz一个没有终结点的请求/ redirecionar para realizar o transbordo'''
data = splitSenderId(self.sender)
logger.info(data)
headers = {
"Content-type": "application/json"
,"Accept": "application/json"
}
try:
r = requests.post(os.environ['TRANSBORDO'], data=json.dumps(data), headers=headers)
if r.status_code is 200:
logger.info(f'Msg {r.text}')
return True
else:
logger.info(f'Erro: {r.text}')
return False
except requests.exceptions.ConnectionError:
logger.info('Erro de Conexao com Transbordo')
return False
