功能实现

新建线程并创建ArkTS基础运行时环境，加载自定义模块请参考napi_load_module_with_info。

#include "napi/native_api.h"
#include <pthread.h>
// ...
static void *CreateArkRuntimeFunc(void *arg)
{
    // 1. 创建基础运行环境
    napi_env env = nullptr;
    napi_status ret = napi_create_ark_runtime(&env);
    if (ret != napi_ok) {
        return nullptr;
    }

    napi_handle_scope scope = nullptr;
    if (napi_open_handle_scope(env, &scope) != napi_ok) {
        napi_destroy_ark_runtime(&env);
        return nullptr;
    }

    // 2. 加载自定义模块
    napi_value objUtils = nullptr;
    ret = napi_load_module_with_info(env, "entry/src/main/ets/pages/ObjectUtils", "com.example.myapplication/entry",
                                     &objUtils);
    if (ret != napi_ok) {
        OH_LOG_ERROR(LOG_APP, "Failed to load module");
        napi_close_handle_scope(env, scope);
        napi_destroy_ark_runtime(&env);
        return nullptr;
    }

    // 3. 使用ArkTS中的logger
    napi_value logger = nullptr;
    ret = napi_get_named_property(env, objUtils, "Logger", &logger);
    if (ret != napi_ok) {
        napi_close_handle_scope(env, scope);
        napi_destroy_ark_runtime(&env);
        return nullptr;
    }
    ret = napi_call_function(env, objUtils, logger, 0, nullptr, nullptr);
    if (ret != napi_ok) {
        napi_close_handle_scope(env, scope);
        napi_destroy_ark_runtime(&env);
        return nullptr;
    }

    napi_close_handle_scope(env, scope);

    // 4. 销毁ArkTS环境
    ret = napi_destroy_ark_runtime(&env);
    if (ret != napi_ok) {
        OH_LOG_ERROR(LOG_APP, "Failed to destroy ark runtime");
    }

    return nullptr;
}

static napi_value CreateArkRuntime(napi_env env, napi_callback_info info)
{
    pthread_t tid;
    pthread_create(&tid, nullptr, CreateArkRuntimeFunc, nullptr);
    pthread_join(tid, nullptr);
    return nullptr;
}

ArkTS导入头文件
```
import testNapi from 'libentry.so';
```

ArkTS代码示例

export function Logger() {
  console.info('print log');
}

// index.ets
testNapi.createArkRuntime();
