#鸿蒙通关秘籍#开发的时候，如果里得用到Native软件包，这个咋配置？

咱们要想在HarmonyOS应用中使用Native软件包，进行一些配置和代码编写是基本工作。

然后得在`module.json5`文件中配置Native模块的路径和参数，比如：

{
  "apiType": "stageMode",
  "buildOption": {
    "externalNativeOptions": {
      "path": "./src/main/cpp/CMakeLists.txt",
      "arguments": "",
      "abiFilters": [
        "arm64-v8a",
        "x86_64"
      ],
      "cppFlags": ""
    }
  },
  "targets": [
    {
      "name": "default",
      "runtimeOS": "HarmonyOS"
    }
  ]
}

EXTERN_C_START
static napi_value Init(napi_env env, napi_value exports) {
  // 注册Native函数
  napi_property_descriptor desc[] = {
    { "myHypot", nullptr, MyHypot, nullptr, nullptr, nullptr, napi_default, nullptr }
  };
  if(napi_ok != napi_define_properties(env, exports, sizeof(desc) / sizeof(desc[0]), desc)) {
    return nullptr;
  }
  return exports;
}
EXTERN_C_END

static napi_module demoModule = {
  .nm_version = 1,
  .nm_flags = 0,
  .nm_filename = nullptr,
  .nm_register_func = Init,
  .nm_modname = "hello",
  .nm_priv = ((void*)0),
  .reserved = { 0 },
};
extern "C" __attribute__((constructor)) void RegisterEntryModule(void) {
  napi_module_register(&demoModule);
}

import libHello from 'libhello.so';
