HarmonyOS 鸿蒙Next 如何在C层获取一个hashmap或者自定义对象数据

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);
    assert(status == napi_ok);

    napi_value onCallBack1, str_arg;
    status = napi_get_named_property(env, js_cb, "onCallBack1", &onCallBack1);
    assert(status == napi_ok);

    status = napi_create_string_utf8(env, "mangguo", strlen("mangguo"), &str_arg);
    assert(status == napi_ok);

    size_t cb1argc = 1;
    status = napi_call_function(env, js_cb, onCallBack1, cb1argc, &str_arg, nullptr);

    size_t cb2argc = 1;
    napi_value onCallBack2, int_arg;
    status = napi_get_named_property(env, js_cb, "onCallBack2", &onCallBack2);
    status = napi_create_int32(env, 2, &int_arg);
    assert(status == napi_ok);

    status = napi_call_function(env, js_cb, onCallBack2, cb2argc, &int_arg, nullptr);
    assert(status == napi_ok);

    napi_value oncallback3, arg_object;
    status = napi_get_named_property(env, js_cb, "onCallBack3", &oncallback3);
    assert(status == napi_ok);

    status = napi_create_object(env, &arg_object);
    assert(status == napi_ok);

    napi_value testNum, testString;
    status = napi_create_int32(env, 123, &testNum);
    assert(status == napi_ok);

    status = napi_set_named_property(env, arg_object, "testNum", testNum);
    assert(status == napi_ok);

    status = napi_create_string_utf8(env, "mangguo", strlen("mangguo"), &testString);
    assert(status == napi_ok);

    status = napi_set_named_property(env, arg_object, "testString", testString);
    assert(status == napi_ok);

    status = napi_call_function(env, js_cb, oncallback3, cb2argc, &arg_object, nullptr);
    assert(status == napi_ok);

    return nullptr;
}

导入：import testNapi from ‘libentry.so’;
使用：testNapi.transobject(tscb);
