需要调起系统相册，选择一张图片，并能获取到选择到的图片，应该如何实现

invokeCamera(callback?: (uri: string) => void) { 
const context = getContext(this) as common.UIAbilityContext 
context.startAbilityForResult({ 
action: “ohos.want.action.imageCapture”, 
parameters: { 
callBundleName: “com.neo.myapplication” //本应用bundlename 
} 
}, (err: BusinessError, data: common.AbilityResult) => { 
if (err && err.code != 0) { 
console.error(“imageCapture error:” + ${JSON.stringify(err)}); 
return; 
} 
console.warn(“imageCapture data:” + ${JSON.stringify(data)}); 
let uri = data?.want?.parameters?.resourceUri; 
if (callback && uri) { 
  callback(uri.toString()); 
} 
}) 
}
