> 因为我看过这段代码 ‘’‘ for key, valRaw := range dubbo3Resp.Attachments() { switch
valRaw.(type) { case string: trailer[key] = []string{valRaw.(string)} case
[]string: trailer[key] = valRaw.([]string) default:
panic(fmt.Sprintf("unsupported attachment value type %T", valRaw)) } } ’‘’
直接panic了，所以我也没做处理。其实统一，到底能不能传非string或者[]string的值。而且到接收端，从其他结构变成string，感觉也不适合，真正的完美应该可以支持所有类型，接收端能够反序列化
如果想要支持所有类型的话，建议放在reqs,
resp结构体中，triple的attachments是放在http协议的header中，将header字段序列化反序列化太奇怪了
