I really like aspnetboilerplate framework, I learning/using it now..

您如何在AppServices中为aspnetboilerplate执行文件上传"逻辑/方法?我已经弄清楚了有角的部分，并且工作正常.

How do you do 'File Upload' logic/method in AppServices for aspnetboilerplate? The angular part have I figured out and is working fine.

打算如何在appservice层中编写接收文件上传的方法?关于粗俗有很好的例子，并且大张旗鼓地把它们弄清楚.现在我要实现文件上传.甚至可以在appservice层中做到这一点，还是必须在控制器方法中做到这一点?

How is it intended to write the methods receiving a file upload in the appservice layer? There is good examples on crud, and swagger figures them out. Now I want to implement file upload. Is this even possible in the appservice layer, or do I have to do this in the controller methods?

推荐答案

无法通过Appservice上传文件，您需要使用此操作的特定方法创建Web Api控件.

There is no way to upload a file from Appservice you need to create a web Api controler with a particular method for this action.

  public class EntityImageController : AbpApiController
 {
      private IEntityImageAppService iEntityAppService;

      public EntityImageController( IEntityImageAppService pEntityImgAppService ) : base()
      {
           this.LocalizationSourceName = AppConsts.LocalizationSourceName;
           this.iEntityImgAppService = pEntityImgAppService;
      }          

      [AbpAuthorize( PermissionNames.Entity_Update )]
      [HttpPost]
      public async Task<HttpResponseMessage> Set()
      {

           // Check if the request contains multipart/form-data.
           if( !Request.Content.IsMimeMultipartContent() )
           {
                throw new HttpResponseException( HttpStatusCode.UnsupportedMediaType );
           }

           string root = HttpContext.Current.Server.MapPath( "~/App_Data" );
           var provider = new MultipartFormDataStreamProvider( root );

           try
           {
                // Read the form data.
                await Request.Content.ReadAsMultipartAsync( provider );

                var mEntityId = provider.FormData[ "EntityId" ];

                MultipartFileData mFileData = provider.FileData.FirstOrDefault();
                var mFileInfo = new FileInfo( mFileData.LocalFileName );
                var mImageBytes = File.ReadAllBytes( mFileInfo.FullName );

                await this.iEntityImgAppService.Set( new EntityImageInput
                {
                     ImageInfo = mImageBytes,
                     EntityId = Convert.ToInt32( mEntityId )
                } );

                return Request.CreateResponse( HttpStatusCode.OK );
           }
           catch( System.Exception e )
           {
                return Request.CreateErrorResponse( HttpStatusCode.InternalServerError, e );
           }
      }

}
