参考文档:
Harmony如何引用har包
List列表使用
通过上面的下载链接下载之后,把har包复制到项目中,在项目src/main目录下新建目录lib,将har包复制进去。
然后在项目的oh-package.json5中添加对har包的引用,添加完成后会报错,只需要将鼠标放在错误处,出现Run 'ohpm install'后执行下就行了。
"dependencies": {
"@app/RefreshLibrary": "file:./src/main/libs/RefreshLibrary_OpenHarmony.har"
}
引用成功后会在项目目录下生成一个oh_modules目录,如果有@app/RefreshLibrary则成功,无则失败。
