#鸿蒙通关秘籍#在鸿蒙开发中调用ArkTS中的newSendable函数步骤详解

在鸿蒙应用开发中调用ArkTS的newSendable函数包括以下步骤：首先，通过napi_create_ark_runtime创建执行环境；然后使用napi_load_module_with_info加载模块并获取到指定类的属性；接着，查找到newSendable方法并通过napi_call_function调用；最后，处理返回结果并销毁环境。

cpp #include "napi/native_api.h" #include <thread>

static void *CreateArkRuntimeFunc(void *arg) { napi_env env = nullptr; napi_status ret = napi_create_ark_runtime(&env); if (ret != napi_ok) { std::abort(); } napi_value test = nullptr; ret = napi_load_module_with_info(env, "entry/src/main/ets/pages/SendableObjTest", "com.example.myapplication/entry", &test); if (ret != napi_ok) { std::abort(); } napi_value sendableObjTest = nullptr; ret = napi_get_named_property(env, test, "SendableObjTest", &sendableObjTest); if (ret != napi_ok) { std::abort(); } napi_value newSendable = nullptr; ret = napi_get_named_property(env, sendableObjTest, "newSendable", &newSendable); if (ret != napi_ok) { std::abort(); } napi_value result = nullptr; ret = napi_call_function(env, sendableObjTest, newSendable, 0, nullptr, &result); if (ret != napi_ok) { std::abort(); } int value0; napi_get_value_int32(env, result, &value0); if (value0 != 1024) { std::abort(); } ret = napi_destroy_ark_runtime(&env); return nullptr; }
