如何在休息服务

Question

我正在使用带有rest api后端的ng2-file-upload，没有multer 想知道，如果ng2-file-upload内部正在进行http发布，或者我们需要创建一个服务来做http post

我从演示中获取了代码 https://valor-software.com/ng2-file-upload/

 public uploader:FileUploader = new FileUploader({url: URL,maxFileSize: 
 maxFileSize,autoUpload:true});
 public hasBaseDropZoneOver:boolean = false;
 public hasAnotherDropZoneOver:boolean = false;

 public fileOverBase(e:any):void {
   this.hasBaseDropZoneOver = e;
 }

 public fileOverAnother(e:any):void {
   this.hasAnotherDropZoneOver = e;
 }
}
