Golang sendMessage Examples

Example #1

File: kite_client_manager.go Project: huayl/kiteq

//发送消息
func (self *KiteClientManager) SendMessage(msg *protocol.QMessage) error {
	c, err := self.selectKiteClient(msg.GetHeader())
	if nil != err {
		return err
	}
	return c.sendMessage(msg)
}

Example #2

File: kite_client_manager.go Project: huayl/kiteq

//发送事务消息
func (self *KiteClientManager) SendTxMessage(msg *protocol.QMessage, doTranscation DoTranscation) (err error) {
	//路由选择策略
	c, err := self.selectKiteClient(msg.GetHeader())
	if nil != err {
		return err
	}

	//先发送消息
	err = c.sendMessage(msg)
	if nil != err {
		return err
	}

	//执行本地事务返回succ为成功则提交、其余条件包括错误、失败都属于回滚
	feedback := ""
	succ := false
	txstatus := protocol.TX_UNKNOWN
	//执行本地事务
	succ, err = doTranscation(msg)
	if nil == err && succ {
		txstatus = protocol.TX_COMMIT
	} else {
		txstatus = protocol.TX_ROLLBACK
		if nil != err {
			feedback = err.Error()
		}
	}
	//发送txack到服务端
	c.sendTxAck(msg, txstatus, feedback)
	return err
}
