我正在开发一款需要至少拍摄4张照片的应用程序。我每次拍照都要重新启动相机,这样他们就不必再在应用菜单上再次点击拍照按钮了。到目前为止,这是我的代码:
sh "docker run -d --name mongocontainer19"
sh "docker exec mongocontainer19 mongo mongodump"
然而,相机不会重新启动回相机?有什么理由不行吗?我想我试图在承诺中调用一个函数吗?

也许使用递归你可以做到,我给你一个未经证实的例子,但这可以在逻辑上为你服务:
我根据将其保存在Base 64中的应用程序做了示例,但是根据需要在列表中应用了推送。
pictureList: any[];
ngOnInit(): void {
this.pictureList = null;
this.optionsCamera = {
quality: 50,
destinationType: this._camera.DestinationType.DATA_URL,
encodingType: this._camera.EncodingType.JPEG,
mediaType: this._camera.MediaType.PICTURE,
saveToPhotoAlbum: true
};
this.optionsGallery = {
quality: 50,
destinationType: this._camera.DestinationType.DATA_URL,
sourceType: this._camera.PictureSourceType.PHOTOLIBRARY
};
}
startCamera(): void {
if (this.pictureList.length <= 4) {
console.log('Open in length: ' + this.pictureList.length);
this.getPhoto(this.optionsCamera);
this.startCamera();
}
}
getPhoto(options): void {
this._camera.getPicture(options).then(
imageData => {
let base64Image = "data:image/jpeg;base64," + imageData;
this.pictureList.push(base64Image);
},
err => {
console.log("Could not open the camera: " + err);
}
);
}
