我正在使用ng2-file-upload和rest api后端，没有multer想知道，如果ng2-file-upload正在内部进行http post或者我们需要创建一个服务来做http post
我从demo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;
}
}
