## 安装与使用

请到三方库的 Releases 发布地址查看配套的版本信息：[@tuya-oh/react-native-blob-util Releases](https://gitee.com/rn-mi/ty-react-native-blob-util/releases/tag/0.19.6-rc-0.0.16) 。对于未发布到npm的旧版本，请参考[安装指南](https://gitee.com/react-native-oh-library/usage-docs/blob/master/zh-cn/tgz-usage.md)安装tgz包。

进入到工程目录并输入以下命令：

<!-- tabs:start -->

#### **npm**

```bash
npm install @tuya-oh/react-native-blob-util
```

#### **yarn**

```bash
yarn add @tuya-oh/react-native-blob-util
```

<!-- tabs:end -->

## 使用 Codegen

本库已经适配了 `Codegen` ，在使用前需要主动执行生成三方库桥接代码，详细请参考[ Codegen 使用文档](https://gitee.com/react-native-oh-library/usage-docs/blob/master/zh-cn/codegen.md)。

## Link

目前 HarmonyOS 暂不支持 AutoLink，所以 Link 步骤需要手动配置。

首先需要使用 DevEco Studio 打开项目里的 HarmonyOS 工程 `harmony`

### 1.在工程根目录的 `oh-package.json5` 添加 overrides 字段

```
{
  ...
  "overrides": {
    "@rnoh/react-native-openharmony" : "./react_native_openharmony"
  }
}
```

### 2.引入原生端代码

目前有两种方法：

1. 通过 har 包引入（在 IDE 完善相关功能后该方法会被遗弃，目前首选此方法）；
2. 直接链接源码。

方法一：通过 har 包引入

> [!TIP] har 包位于三方库安装路径的 `harmony` 文件夹下。

打开 `entry/oh-package.json5`，添加以下依赖

```json
"dependencies": {
     "@rnoh/react-native-openharmony": "file:../react_native_openharmony",
     "@tuya-oh/react-native-blob-util": "file:../../node_modules/@tuya-oh/react-native-blob-util/harmony/blobUtil.har"
  }
```

点击右上角的 `sync` 按钮

或者在终端执行：

```bash
cd entry
ohpm install
```

方法二：直接链接源码

> [!TIP] 如需使用直接链接源码，请参考[直接链接源码说明](https://gitee.com/react-native-oh-library/usage-docs/blob/master/zh-cn/link-source-code.md)

### 3.在 ArkTs 侧引入 BlobUtilPackage

打开 `entry/src/main/ets/RNPackagesFactory.ts`，添加：

```diff
+ import {BlobUtilPackage} from '@tuya-oh/react-native-blob-util/ts';

export function createRNPackages(ctx: RNPackageContext): RNPackage[] {
  return [
+   new BlobUtilPackage(ctx)
  ];
}
```

### 4.配置 CMakeLists 和引入 react-native-blob-util

打开 `entry/src/main/cpp/CMakeLists.txt`，添加：

```diff
project(rnapp)
cmake_minimum_required(VERSION 3.4.1)
set(CMAKE_SKIP_BUILD_RPATH TRUE)
set(RNOH_APP_DIR "${CMAKE_CURRENT_SOURCE_DIR}")
set(NODE_MODULES "${CMAKE_CURRENT_SOURCE_DIR}/../../../../../node_modules")
+ set(OH_MODULES "${CMAKE_CURRENT_SOURCE_DIR}/../../../oh_modules")
set(RNOH_CPP_DIR "${CMAKE_CURRENT_SOURCE_DIR}/../../../../../../react-native-harmony/harmony/cpp")
set(LOG_VERBOSITY_LEVEL 1)
set(CMAKE_ASM_FLAGS "-Wno-error=unused-command-line-argument -Qunused-arguments")
set(CMAKE_CXX_FLAGS "-fstack-protector-strong -Wl,-z,relro,-z,now,-z,noexecstack -s -fPIE -pie")
set(WITH_HITRACE_SYSTRACE 1) # for other CMakeLists.txt files to use
add_compile_definitions(WITH_HITRACE_SYSTRACE)

add_subdirectory("${RNOH_CPP_DIR}" ./rn)

# RNOH_BEGIN: manual_package_linking_1
add_subdirectory("../../../../sample_package/src/main/cpp" ./sample-package)
+ add_subdirectory("${OH_MODULES}/@tuya-oh/react-native-blob-util/src/main/cpp" ./blobUtil)
# RNOH_END: manual_package_linking_1

file(GLOB GENERATED_CPP_FILES "./generated/*.cpp")

add_library(rnoh_app SHARED
    ${GENERATED_CPP_FILES}
    "./PackageProvider.cpp"
    "${RNOH_CPP_DIR}/RNOHAppNapiBridge.cpp"
)
target_link_libraries(rnoh_app PUBLIC rnoh)

# RNOH_BEGIN: manual_package_linking_2
target_link_libraries(rnoh_app PUBLIC rnoh_sample_package)
+ target_link_libraries(rnoh_app PUBLIC rnoh_blob_util)
# RNOH_END: manual_package_linking_2
```

### 5.运行

点击右上角的 `sync` 按钮

或者在终端执行：

```bash
cd entry
ohpm install
```

然后编译、运行即可。

### 6.release包的使用

> 执行完'npm install @tuya-oh/react-native-blob-util@x.x.x'命令后，在生成的node_modules/npm install @tuya-oh/react-native-blob-util中即可获取release包。

打开 `entry/src/main/cpp/CMakeLists.txt`，添加：

```diff
project(rnapp)
cmake_minimum_required(VERSION 3.4.1)
set(CMAKE_SKIP_BUILD_RPATH TRUE)
set(NATIVERENDER_ROOT_PATH "${CMAKE_CURRENT_SOURCE_DIR}")
set(OH_MODULE_DIR "${CMAKE_CURRENT_SOURCE_DIR}/../../../oh_modules")
set(RNOH_CPP_DIR "${OH_MODULE_DIR}/@rnoh/react-native-openharmony/include")
set(REACT_COMMON_PATCH_DIR "${RNOH_CPP_DIR}/patches/react_native_core")

set(CMAKE_CXX_STANDARD 17)
set(LOG_VERBOSITY_LEVEL 1)
set(CMAKE_ASM_FLAGS "-Wno-error=unused-command-line-argument -Qunused-arguments")
set(RNOH_GENERATED_DIR "${CMAKE_CURRENT_SOURCE_DIR}/generated")
set(CMAKE_CXX_FLAGS "-fstack-protector-strong -Wl,-z,relro,-z,now,-z,noexecstack -s -fPIE -pie -DNDEBUG")
set(WITH_HITRACE_SYSTRACE 1) # for other CMakeLists.txt files to use
add_compile_definitions(WITH_HITRACE_SYSTRACE)
# folly的编译选项
set(folly_compile_options
    -DFOLLY_NO_CONFIG=1
    -DFOLLY_MOBILE=1

    -Wno-comma
    -Wno-shorten-64-to-32
    -Wno-documentation
    -faligned-new
)
add_compile_options("-Wno-unused-command-line-argument")
# 添加头文件目录
include_directories(${NATIVERENDER_ROOT_PATH}
                    ${RNOH_CPP_DIR}
                    ${REACT_COMMON_PATCH_DIR}

### 7.字节码格式的release包使用

字节码格式的release包是指在release模式下编译出来、ets文件转换成了.abc、C++源码转换成.so的har包，其命名格式为 react_native_openharmony_abc-x.x.x.xxx.har。 字节码格式的release包使用方式跟release包使用大体上是一样的，主要有两点需要注意：

1. 使用字节码格式的release包需要将工程级的 build-profile.json5 文件中将 useNormalizedOHMUrl 设置为 true，如：

   ```diff
     "products": [
       {
         "name": "default",
         "signingConfig": "default",
         "compatibleSdkVersion": "5.0.1(14)",
         "runtimeOS": "HarmonyOS",
   +     "buildOption": {
   +       "strictMode": {
   +          "useNormalizedOHMUrl": true
   +       }
   +     }
       }
     ],
   ```
