以视频文件为例，需要在module.json5文件中增加如下配置。{
"module": {
"name": "entry",
"type": "entry",
"description": "$string:module_desc",
"mainElement": "EntryAbility",
"deviceTypes": [
"phone"
],

"installationFree": false,
"pages": "$profile:main_pages",
"abilities": [
{
"name": "EntryAbility",
"srcEntry": "./ets/entryability/EntryAbility.ets",
"description": "$string:EntryAbility_desc",
"icon": "$media:layered_image",
"label": "$string:EntryAbility_label",
"startWindowIcon": "$media:startIcon",
"startWindowBackground": "$color:start_window_background",
"exported": true,
"skills": [
{
"entities": [
"entity.system.home"
],
"actions": [
"ohos.want.action.home",
"ohos.want.action.viewData" // 必填，声明数据处理能力
],
"uris": [
{
// 允许打开uri中以file://协议开头标识的本地文件
"scheme": "file", // 必填，声明协议类型为文件
"type": "general.video", // 必填，表示支持打开的文件类型
"linkFeature": "FileOpen" // 必填且大小写敏感，表示此URI的功能为文件打开
}
]
}
]
}
],
"extensionAbilities": [
{
"name": "EntryBackupAbility",
"srcEntry": "./ets/entrybackupability/EntryBackupAbility.ets",
"type": "backup",
"exported": false,
"metadata": [
{
"name": "ohos.extension.backup",
"resource": "$profile:backup_config"
}
],
}
]
}
} 声明了文件打开的应用在被拉起后，获取传入的Want参数信息，从中获取待打开文件的URI。import { ConfigurationConstant, UIAbility, Want } from '@kit.AbilityKit';

} catch (err) {
hilog.error(DOMAIN, 'testTag', 'Failed to set colorMode. Cause: %{public}s', JSON.stringify(err));
}
hilog.info(DOMAIN, 'testTag', '%{public}s', 'Ability onCreate');
// 从want信息中获取uri字段
let uri = want.uri;
if (uri == null || uri == undefined) {
console.info('uri is invalid');
return;
}
// 将uri信息保存至全局变量中
AppStorage.setOrCreate<string>("fileUri", uri);

AppStorage.setOrCreate<string>("fileUri", uri);
this.uiContext?.getRouter().pushUrl({

}).catch((error: BusinessError) => {
console.error(`error:${error.message}`);
});
}
onDestroy(): void {
hilog.info(DOMAIN, 'testTag', '%{public}s', 'Ability onDestroy');
}

}
hilog.info(DOMAIN, 'testTag', 'Succeeded in loading the content.');
});
windowStage.getMainWindow((err: BusinessError, data: window.Window) => {
