HarmonyOS NAPI中如何将C++中的结构体回调给ArkTS

//创建类Struct用于接收C++侧结构体中的数据 
export class Struct{ 
  age: number = 0; 
  name: string = 'example'; 
}; 
export class tsClass{ 
  public onCallBack1(age: number){ 
    //对age进行操作 
    console.log("testcallback1" + age) 
  } 
  public onCallBack2(name: string){ 
    //对name进行操作 
    console.log("testcallback2" + name) 
  } 
  public onCallBack3(cbStruct: Struct){ 
    //对cbStruct进行操作 
    console.log("testcallback3 " + cbStruct.age + " " + cbStruct.name) 
  } 
}

export const transObject: (a: Object) => void; 

//定义一个结构体 
struct Person{ 
  int age; 
  std::string name; 
}; 
static napi_value TransObject(napi_env env, napi_callback_info info){ 
  napi_status status; 
  size_t argc = 1; 
  napi_value js_cb; 
  status = napi_get_cb_info(env, info, &argc, &js_cb, nullptr, nullptr); 
  // 获取TS 对象的函数 oncallback3 
  napi_value oncallback3, arg_object; 
  status = napi_get_named_property(env, js_cb, "onCallBack3", &oncallback3); 
  // native 层创建对象arg_object 
  status = napi_create_object(env, &arg_object); 
  napi_value age, name, cbargc; 
  Person person; 
  person.name = "Alice"; 
  person.age = 30; 
  //给arg_object对象的属性age赋值 
  status = napi_create_int32(env, person.age, &age); 
  status = napi_set_named_property(env, arg_object, "age", age); 
  //给arg_object对象的属性name赋值 
  const char* p1name = person.name.c_str(); 
  status = napi_create_string_utf8(env, p1name, sizeof(person.name), &name); 
  status = napi_set_named_property(env, arg_object, "name", name); 
  // 调用TS 对象的方法 onCallBack3,并将上面创建的对象arg_object，作为函数参数传递 
  status = napi_call_function(env, js_cb, oncallback3, 1, &arg_object, nullptr); 
 
  return nullptr; 
}
