How to set an Url of the Application layer Method #783

sampath created 8 years ago

Hi, I have developed below mentioned code snippets for the app with the WebApi (not for the ABP app).So my question is how can I replace Application Layer method instaed of the Web api Url below (i.e. url: "/api/EventImages/AddPictures",) ? Thanks.

Note : In other words how can I implement below kind of implementation with the ABP.

//to add Pictures
            vm.AddPictures = function ($files) {
                vm.upload = [];
                for (var i = 0; i < $files.length; i++) {
                    var $file = $files_;
                    (function (index) {
                        vm.upload[index] = $upload.upload({
                            url: "/api/EventImages/AddPictures",
                            method: "POST",
                            data: {},
                            file: $file
                        }).progress(function (evt) {
                         }).success(function (data, status, headers, config) {
                          }).error(function (data, status, headers, config) {
                         });
                    })(i);
                }
            };

[i:2h7l3lfn]Web Api method which above app has been consumed_

[HttpPost]
        public async Task<HttpResponseMessage> AddPictures()
        {
            if (!Request.Content.IsMimeMultipartContent())
            {
                this.Request.CreateResponse(HttpStatusCode.UnsupportedMediaType);
            }

            var newImageName = string.Empty;
            var path = System.Web.Hosting.HostingEnvironment.MapPath("~");
            var provider = GetMultipartProvider();
            await Request.Content.ReadAsMultipartAsync(provider);

            foreach (var r in provider.FileData)
            {
                var uploadedFileInfo = new FileInfo(r.LocalFileName);
                var uploadedFileName = uploadedFileInfo.Name;
                var originalFileName = GetDeserializedFileName(r);
                var extension = Path.GetExtension(originalFileName);
                if (extension == null) continue;

                var ext = extension.ToLower();
                var guid = Guid.NewGuid().ToString();
                newImageName = guid + ext;

                try
                {
                    File.Move(path + "\\Resources\\images\\temp\\" + uploadedFileName, path + "\\Resources\\images\\event-images\\" + newImageName);
                }
                catch (IOException ex)
                {
                    //Write error
                }
            }

            return Request.CreateResponse(HttpStatusCode.OK, new { newImageName });
        }

Hi,

I suggest you to create regular web api controller, instead of application service method. Because, your code seems web related and should be in the web layer.

Hi, Perfect it works.I have created a new webApi controller on the WebApi Layer as PictureController .Thanks a lot :)

Here is the complete code snippet.

public class PictureController : IPApiControllerBase
    {

        /// <summary>
        /// to Add Pictures
        /// </summary>
        [HttpPost]
        public async Task<HttpResponseMessage> AddPictures()
        {
            if (!Request.Content.IsMimeMultipartContent())
            {
                this.Request.CreateResponse(HttpStatusCode.UnsupportedMediaType);
            }

            var newImageName = string.Empty;
            var path = System.Web.Hosting.HostingEnvironment.MapPath("~");
            var provider = GetMultipartProvider();
            await Request.Content.ReadAsMultipartAsync(provider);

            foreach (var r in provider.FileData)
            {
                var uploadedFileInfo = new FileInfo(r.LocalFileName);
                var uploadedFileName = uploadedFileInfo.Name;
                var originalFileName = GetDeserializedFileName(r);
                var extension = Path.GetExtension(originalFileName);
                if (extension == null) continue;

                var ext = extension.ToLower();
                var guid = Guid.NewGuid().ToString();
                newImageName = guid + ext;

                try
                {
                    File.Move(path + "\\Common\\temp\\" + uploadedFileName, path + "\\Common\\pictures\\" + newImageName);
                }
                catch (IOException ex)
                {
                    //Write error
                }
            }

            return Request.CreateResponse(HttpStatusCode.OK, new { newImageName });
        }

        #region Private Methods

        /// <summary>
        /// to Get Multi part Provider
        /// </summary>
        private MultipartFormDataStreamProvider GetMultipartProvider()
        {
            const string uploadFolder = "~/Common/temp";
            var root = HttpContext.Current.Server.MapPath(uploadFolder);
            Directory.CreateDirectory(root);
            return new MultipartFormDataStreamProvider(root);
        }

        /// <summary>
        /// to Get De-serialized File Name
        /// </summary>
        private string GetDeserializedFileName(MultipartFileData fileData)
        {
            var fileName = GetFileName(fileData);
            return JsonConvert.DeserializeObject(fileName).ToString();
        }

        /// <summary>
        /// to Get File Name
        /// </summary>
        private string GetFileName(MultipartFileData fileData)
        {
            return fileData.Headers.ContentDisposition.FileName;
        }

        #endregion Private Methods

    }
