triple协议如何能够配置随机端口呢？同一台机器部署多个相同服务，端口会重复，java中协议端口可以允许-1端口随机分配

调整代码

不要默认值是不是才能通过后面逻辑？，否则后面判断端口逻辑是无效的？

Thank you for reporting this. Firstly, the documentation you referenced is from Dubbo, not Dubbo-go. Therefore, the default port is not the same as the Dubbo's. Then, the condition of using ramdon port doesn't have problem, since the port should be specified to -1, instead of leaving empty.

@justxuewei Thank you your reply, But use "-1" in port field of string type, the length size is greater than 0, if i keep empty the field default is "20000",

there you are set the "default" tag value "20000", please give a simple of how to use random port?

thank you very much

use "-1" in port field of string type, the length size is greater than 0

What is happend while the length size is greater than 0? Does it not work while setting the port to -1?

Could you give me a link to this line of code? Instead of a picture. I'll take a look at this.

the code you are parse "default" tag, Port default "20000"
https://github.com/apache/dubbo-go/blob/main/config/protocol_config.go

my dubbogo.yaml config

dubbo:
  application: 
    name: go.micro.api.gateway
  registries:
    nacos:
      protocol: nacos
      address: 192.168.1.236:8848
  protocols:
    triple:
      name: tri
      port:  -1

感觉是判断-1才特殊处理？现在无法解析就随机分配 无法解析结束进程panic感觉比较合理
