Http转dubbo协议的List类型不支持结构体元素类型

[lionelStuart]

MyResponse getPosition(Position pos);

public class Position implements Serializable {

    public String name;

    public Long age;

    public Integer weight;

    public Float height;

    private Date born;

    private List<TagsModel> innerTags;

    private Map<String, TagsModel> innerMap;

    private TagsModel outerTag;

    private List<String> funs;
}

# 服务端日志
# getPosition get pos = Position(name=jim, age=7, weight=60, height=187.0, born=Mon Jan 01 19:00:29 CST 2024, innerTags=[null, null], innerMap={a=TagsModel{id=1, name='null', postId=null, addBy='ssss'}, b=TagsModel{id=3, name='null', postId=null, addBy='bbbb'}}, outerTag=TagsModel{id=10, name='ffff', postId=null, addBy='null'}, funs=[a, b, c])

定义上面的dubbo接口，解析字段中List 解析出来为[null, null]，Map解析出来为nnerMap={a=TagsModel{id=1, name='null', postId=null, addBy='ssss'}，看起来List应该还不支持结构体类型的元素 从代码来看也能应证

void DubboUtility::createUntypedListObjcet(const json& object,
                                           Hessian2::Object::UntypedList& untyped_list) {
  auto type = object.type();
  switch (type) {
  case json::value_t::string:
    untyped_list.emplace_back(std::make_unique<Hessian2::StringObject>(object.get<std::string>()));
    break;
  case json::value_t::number_unsigned:
  case json::value_t::number_integer:
    untyped_list.emplace_back(std::make_unique<Hessian2::IntegerObject>(object.get<int64_t>()));
    break;
  case json::value_t::number_float:
    untyped_list.emplace_back(std::make_unique<Hessian2::DoubleObject>(object.get<double>()));
    break;
  case json::value_t::boolean:
    untyped_list.emplace_back(std::make_unique<Hessian2::BooleanObject>(object.get<bool>()));
    break;
  case json::value_t::binary:
    untyped_list.emplace_back(std::make_unique<Hessian2::BinaryObject>(object.get_binary()));
    break;
  case json::value_t::null:
  default:
    untyped_list.emplace_back(std::make_unique<Hessian2::NullObject>());
    break;
  }
}

@sjtuzbk 帮忙看看

[sjtuzbk]

是的，目前只支持List里存放一些基础的类型，对于object可以研究下尝试通过递归来实现。已将此issue置为help wanted，感兴趣的话可以认领

@sjtuzbk 请问能让我试试吗？

请问可否提供一个简单的demo？@lionelStuart
