Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@capacitor-ohos/app-launcher

v8.0.1

Published

The AppLauncher API allows your app to check if an app can be opened and open it.

Readme

@capacitor/app-launcher

zh-CN en

本项目基于 @capacitor/[email protected] 开发。

简介

@capacitor/app-launcher是Capacitor生态系统中的核心插件,用于判断一个url是否可以被打开,为跨平台应用开发提供设备差异化适配能力,兼容Capacitor的Android、iOS等主流移动平台及浏览器环境,本文档只说明在OpenHarmony系统中的使用。

API提供全局 app-launcher 对象,该对象在注册插件后可用,可用于判断一个url是否可以被打开、以及打开一个url的操作,满足各类URL调用场景需求。

支持平台

  • OpenHarmony:5.0+

下载安装

通过命令行或手动引入即可快速安装插件,支持从npm仓库获取。

命令行安装(推荐)

安装hionic CLI:

npm install -g hionic

以下两种方式中任选其一即可,无需重复操作:

npm安装:

# 安装插件
npm install @capacitor/app-launcher

# 同步插件
hionic sync

hionic CLI安装:

hionic plugin add @capacitor/app-launcher

手动引入安装

根据插件源码中 plugin.xml 配置在项目中引入插件:

1. 添加插件配置

根据 plugin.xmlconfig-json 项,通过 target 字段找到 entry 模块中 capacitor.plugins.json 文件,并根据 param 标签添加配置如下:

[
  {
    "pkg": "@capacitor/app-launcher",
    "classpath": "AppLauncher"
  }
]

2. 修改 CMake 配置

根据 plugin.xmlCMakeLists 项,通过 modules-name 字段找到模块 capacitor,路径为 target 字段的 CMakeLists.txt 文件,并添加 add_subdirectorytarget_link_libraries 如下:

#START_ADD_SUBDIRECTORY
// ...
add_subdirectory(AppLauncher)
// ...
#END_ADD_SUBDIRECTORY

// ...

target_link_libraries(capacitor PUBLIC
  "-Wl,--whole-archive"
  // ...
  AppLauncher
  // ...
  "-Wl,--no-whole-archive"
)

3. 复制源码文件

根据 plugin.xmlsource-file 项,根据 src 字段找到需要复制的文件,并根据 modules-name 字段和 target-dir 字段找到文件复制的具体模块和目录:

将源码中src/main/cpp/AppLauncher目录下的AppLauncher.h、AppLauncher.cpp、CMakeLists.txt文件引入到capacitor模块中src/main/cpp/AppLauncher目录下。

将源码中src/main/ets/components/AppLauncher目录下的AppLauncher.ets文件引入到capacitor模块中src/main/ets/components/AppLauncher目录下。

4. 添加 ArkTS 配置

capacitor模块的build-profile.json5文件中,buildOption/arkOptions/runtimeOnly/sources配置项数组中加入步骤 3 中拷贝的 ets 文件路径:

{
  "buildOption": {
    // ...
    "arkOptions": {
      "runtimeOnly": [
        // ...
        "./src/main/ets/components/AppLauncher/AppLauncher.ets"
        // ...
      ]
    }
  }
}

卸载

# 卸载 app-launcher 插件
hionic plugin remove @capacitor/app-launcher

约束与限制

兼容性

在以下版本中已测试通过:

  • capacitor: 8.0.0-ohos-8.0.0; SDK: 5.0.5(17); IDE: DevEco Studio: 6.0.0; ROM: 5.1.0.150;

权限要求

OpenHarmony系统中,AppLauncher插件需申请网络权限,需在主工程的 module.json5requestPermissions 中添加 ohos.permission.INTERNET 权限,配置示例如下:

{
  "requestPermissions": [
    {
      // 插件AppLauncher所需权限
      "name": "ohos.permission.INTERNET"
    }
  ]
}

白名单配置

配置canOpenLink相关的白名单,在主工程配置中添加如下内容:

{
  "uris": [
    {
      // 自定义Scheme名称(如myapp、myproject)
      "scheme": "capacitorPlugin",
      // 主机名
      "host": "app"
    }
  ]
}

使用示例

示例1:判断一个url是否可以被打开

import { AppLauncher } from '@capacitor/app-launcher';

const handleCanOpenUrl = async () => {
  try {
    const url = 'TestPlugin://app';
    const result = await AppLauncher.canOpenUrl({ url });
    console.log(`URL ${url} ${result.value ? '可以' : '不可以'} 被打开`);
  } catch (error) {
    console.log(`检查URL失败: ${error instanceof Error ? error.message : String(error)}`);
  }
};

示例2:打开一个url

const handleOpenUrl = async () => {
  try {
    const url = 'TestPlugin://app';
    const result = await AppLauncher.openUrl({ url });
    console.log(`URL ${url} ${result.completed ? '已成功' : '未成功'} 打开`);
  } catch (error) {
    console.log(`打开URL失败: ${error instanceof Error ? error.message : String(error)}`);
  }
};

使用说明

AppLauncher是插件导出对象,可直接导入使用,导入后即可调用插件提供的所有方法,调用便捷高效,所有API均基于Promise实现,支持异步调用。

| 方法名 | 返回类型 | 描述 | 备注 | |--------------------------------------------------------------|------------------------------------------------------|----------------------|---------------| | canOpenUrl(options: CanOpenURLOptions) | Promise<CanOpenURLResult> | 检查是否可以使用给定的URL打开某个应用 | 需配置URL白名单 | | openUrl(options: OpenURLOptions) | Promise<OpenURLResult> | 打开指定的URL | 需申请网络权限、配置白名单 |
