电容器-试图捕捉相机上的取消

public async takePicture(): Promise<string> {

    const image: CameraPhoto = await Camera.getPhoto({
        quality: 90,
        allowEditing: true,
        correctOrientation: true,
        resultType: CameraResultType.Uri,
        source: CameraSource.Camera
    }).catch((e) => {
        throw new Error(e);
    });

    return this._IMAGE = image.webPath;
}

我只是试图捕捉和错误,但点击取消不会抛出一个错误相比,科尔多瓦了。我怎样才能赶上火车 cancel 在照相机上
