HarmonyOS 鸿蒙Next 第三方App相关

1.判断第三方App是否已安装

let paylink = 'payapp://startpay?apppid=123456&page=xxx/pay&query=10';

let paydata = bundleManager.canOpenLink(paylink);

if (paydata) {

  // 应用已安装，可以打开

} else {

  // 应用未安装，不能打开

}

2.打开第三方App

let want: Want = {

  uri: paylink

};

let context = getContext(this) as common.UIAbilityContext;

context.startAbility(want, (error: BusinessError) => {

  console.error(`error.code = ${error.code}`);

});

3.处理未安装的情况

const want: Want = {

  uri: `store://appgallery.huawei.com/app/detail?id=C1229502635594278976`

}

const context = getContext(this) as common.UIAbilityContext;

context.startAbility(want).then(() => {

  // 拉起成功

}).catch((error: BusinessError) => {

  console.log('error code:' + error.code + ', message:' + error.message);

});
