使用proto的oneof语法时, 不支持自定义字段名称like [(api.body = "xxxx")]

[huhu415]

这个生成出来的如果是question会是Question. system也是System

message QuestionnaireContent {
    string type = 1 [(api.body) = "type"]; // system, question
    oneof content {
        QuestionnaireQuestion question = 2 [(api.body) = "content"];
        QuestionnaireSystem system = 3 [(api.body) = "content"];
    }
}

生成出来的go代码会忽视json字段

type QuestionnaireContent struct {
	state         protoimpl.MessageState
	sizeCache     protoimpl.SizeCache
	unknownFields protoimpl.UnknownFields

	Type string `protobuf:"bytes,1,opt,name=type,proto3" form:"type" json:"type"` // system, question
	// Types that are assignable to Content:
	//
	//	*QuestionnaireContent_Question
	//	*QuestionnaireContent_System
	Content isQuestionnaireContent_Content `protobuf_oneof:"content"`
}

type QuestionnaireContent_Question struct {
	Question *QuestionnaireQuestion `protobuf:"bytes,2,opt,name=question,proto3,oneof"`
}

type QuestionnaireContent_System struct {
	System *QuestionnaireSystem `protobuf:"bytes,3,opt,name=system,proto3,oneof"`
}

如果我想要改外层的content为小写的时候, 也会报错

message QuestionnaireContent {
    string type = 1 [(api.body) = "type"]; // system, question
    oneof content {
        QuestionnaireQuestion question = 2 [(api.body) = "question"];
        QuestionnaireSystem system = 3 [(api.body) = "system"];
    } [(api.body) = "content,required"];
}

会报错Expected type name.
