[I] [BUG] [dubbo-go]
qiubyte opened a new issue, #3157:
URL: https://github.com/apache/dubbo-go/issues/3157
### ✅ 验证清单
- [x] 🔍 我已经搜索过 [现有 Issues](https://github.com/apache/dubbo-go/issues)，确信这不是重复问题
### 🚀 Go 版本
1.24.0
### 📦 Dubbo-go 版本
v3.3.1
### 🖥️ 服务端配置
dubbo-go v3.3.1
### 💻 客户端配置
terminal curl http
### 🌐 协议配置
triple
### 📋 注册中心配置
nacos v3
### 💾 操作系统
🍎 macOS
### 📝 Bug 描述
问题现象：dubbo-go 使用triple协议暴露服务，希望通过http方式调用传递参数并获取返回值。
错误信息：http body中json数据多传递了参数，或者说有些字段以前存在，现在从proto中被移除了，但是调用端还可能在使用，就会出现invalid_argument的错误。
### 🔄 重现步骤
步骤
1. 定义接收参数
`type GsImportReq struct {
state protoimpl.MessageState `protogen:"open.v1"`
DeviceId *string `protobuf:"bytes,1,opt,name=deviceId,proto3,oneof" json:"deviceId,omitempty"`
unknownFields protoimpl.UnknownFields
sizeCache protoimpl.SizeCache
}`
2. curl 发起http调用
`
正确：
curl -H "Content-Type:application/json" -H "tri-service-group:uac" -H "tri-service-version:1.0.0" -X POST --data '{"deviceId":"tas"}' "http://127.0.0.1:50001/com.cc.uac.facade.UacGsInternalFacade/GsImport"
多加了参数就报错：
curl -H "Content-Type:application/json" -H "tri-service-group:uac" -H "tri-service-version:1.0.0" -X POST --data '{"deviceId":"tas","plat":"saas"}' "http://127.0.0.1:50001/com.cc.uac.facade.UacGsInternalFacade/GsImport"
`
### ✅ 预期行为
期望能收到正确的业务返回值
### ❌ 实际行为
实际provider端返回错误信息。{"code":"invalid_argument","message":"unmarshal into *GsImportReq: proto: (line 1:24): unknown field \"plat\""}
### 💡 可能的解决方案
跟踪代码发现 triple_protocol/codec.go 中使用到 protojson.UnmarshalOptions DiscardUnknown 默认为false，会严格比对参数。
`
func (c *protoJSONCodec) Unmarshal(binary []byte, message any) error {
protoMessage, ok := message.(proto.Message)
if !ok {
return errNotProto(message)
}
if len(binary) == 0 {
return errors.New("zero-length payload is not a valid JSON object")
}
var options protojson.UnmarshalOptions
return options.Unmarshal(binary, protoMessage)
}
`
var options protojson.UnmarshalOptions 是否可以添加DiscardUnknown: true,或者通过配置方式让使用者自己决定要不要严格限制

经社区讨论后是不打算实现了：参数多了报错也没啥问题，参数都改了改升v2了
