HarmonyOS 如何调用系统相机进行拍照？

import common from '@ohos.app.ability.common'; 
 
@Entry 
@Component 
struct ImagePickerPage { 
  @State message: string = 'Hello World'; 
 
  build() { 
    Row() { 
      Column() { 
        Text(this.message) 
          .fontSize(50) 
          .fontWeight(FontWeight.Bold) 
 
        Button("camera Image").onClick(() => { 
          const context = getContext(this) as common.UIAbilityContext 
          console.log('sss') 
          context.startAbilityForResult({ 
            action:"ohos.want.action.imageCapture", 
            parameters:{ 
              callBundleName:"com.hm.imageshow" 
              //拉起系统相机拍照后返回的应用包名 
            } 
          },(err, data) => { 
            console.info("context:" + JSON.stringify(context)) 
            console.info("imageCapture:" + JSON.stringify(data)) 
          }) 
        }) 
      } 
      .width('100%') 
    } 
    .height('100%') 
  } 
}
