HarmonyOS 通过want打开本地图片，选择图库打开无效

import Want from '@ohos.app.ability.Want'; 
import common from '@ohos.app.ability.common'; 
import wantConstant from '@ohos.app.ability.wantConstant'; 
 
let want: Want = { 
  type: fileMimeType, //fileMimeType 文件mime类型 
  uri: 'file://' + uri, //uri 本地图片绝对路径值为 '/storage/Users/currentUser/Documents/1.jpg' 
  flags: wantConstant.Flags.FLAG_AUTH_READ_URI_PERMISSION 
}; 
 
context.startAbility(want, (err: BusinessError, result: common.AbilityResult) => { 
  // do sth ... 
});
