server 测有设置 tag 吗?

server 测有设置 tag 吗?

server是java服务带了preserved.register.source=SPRING_CLOUD,客户端使用了hz client

请问你 res[0] 的 metadata 里面真的是空的吗?

[KafuuEriri]

请问你 res[0] 的 metadata 里面真的是空的吗?

var metadata map[string]string
    serviceName := desc

    // Get serviceName and metadata from desc
    if strings.Contains(desc, "?") {
        queries, _ := url.Parse(desc)
        tags, _ := url.ParseQuery(queries.Query().Encode())

        result := make(map[string]string)
        for key, value := range tags {
            result[key] = value[0]
        }
        metadata = result
        serviceName = strings.Split(desc, "?")[0]
    }

空的metadata来自这段代码，res中的metadata为 preserved.register.source -> SPRING_CLOUD
