代码示例如下：

import picker from '@ohos.file.picker'; 
import { BusinessError } from '@ohos.base'; 
import common from '@ohos.app.ability.common'; 
import web_webview from '@ohos.web.webview'; 
class pickImage { 
  constructor() {} 
  testPickImage(): string { 
    let PhotoSelectOptions = new picker.PhotoSelectOptions(); 
    PhotoSelectOptions.MIMEType = picker.PhotoViewMIMETypes.IMAGE_TYPE; 
    PhotoSelectOptions.maxSelectNumber = 5; 
    let photoPicker = new picker.PhotoViewPicker(); 
    photoPicker.select(PhotoSelectOptions).then((PhotoSelectResult: picker.PhotoSelectResult) => { 
      console.info('PhotoViewPicker.select successfully, PhotoSelectResult uri: ' + JSON.stringify(PhotoSelectResult)); 
    }).catch((err: BusinessError) => { 
      console.error('PhotoViewPicker.select failed with err: ' + JSON.stringify(err)); 
    }); 
    return '121'; 
  } 
} 
class cameraImage { 
  constructor() {} 
  testCameraImage(): string { 
    const context = getContext(this) as common.UIAbilityContext 
    context.startAbilityForResult({ 
      action:'ohos.want.action.imageCapture', 
      parameters:{ 
        callBundleName:'com.hm.imageshow' } 
    },(err,data) => { 
      console.info('imageCapture:' + `${JSON.stringify(data) 
      }`) 
    }) 
    return '1221'; 
  } 
}
