I've been able to integrate some scheduled web service calls into my Umbraco site that uses the response from the web service to update some of the content on my site. I can now handle text and some various other content but my main query is how should I deal with images that are delivered from the web service in byte[] format?
For a little context, the site I am developing uses web service calls to retreive the details of a product which users of our desktop software have created on their machine. Each of these products is pulled via a web service call into my Umbraco site and created as an individual product page under the parent node of products.
Products > Product
Each product has several properties such as an ID, a name, notes and a collection of images. Once I have called my web service I am creating these pages using the following code:
//Construct Service Request
svc = new StaticDataWebServiceSoapClient();
var response = svc.GetProducts(ref compressionSoapHeader,ref managedUserHeader);
//Umbraco Content Services
int rootID = 1117;
IContentService cs = ApplicationContext.Current.Services.ContentService;
var remove = cs.GetChildren(rootID).Where(x => x.ContentType.Alias == "product");
foreach (var child in remove)
{
cs.Delete(child);
}
foreach(var product in response){
var item = cs.CreateContent(product.ContinentName, rootID, "product");
//Set the properties using the SetValue method, passing in the alias of the property and the value to assign to it
item.SetValue("continentId", product.Id);
item.SetValue("continentName", product.ProductName);
item.SetValue("continentNotes", product.Notes);
foreach (var image in product.Images)
{
??? destination.SetValue("ProductImages", image._Image); ???
image.Caption;
image.FileName;
image.ImageId;
image.KeywordID;
}
cs.SaveAndPublishWithStatus(item);
}
As you can see from the code, each product has several images associated with it that I would also like to pull into the site and associate with the product page that is being created. How would I go about doing this? Would I need to use the Media Service and a specific datatype or would this structure fit easily into a multiple media picker?
You may find it easiest to loop through the images once you've retrieved them and create a new Media item for each of them, and then associate them with the product using a property based on something like the Multiple Media Picker datatype as you noted.
Because this data type stores it's values as a comma separated list of id's you could use something like the following:
// Setup
IContentService cs = ApplicationContext.Current.Services.ContentService;
var mediaService = ApplicationContext.Current.Services.MediaService;
int mediaRootId = 1111; // Replace with the id of your media parent folder
// Replace the image looping logic with the following:
// MultiMediaPicker stores it's values as a commma separated string of ids.
string imageIds = string.Empty;
foreach (var image in product.Images)
{
var fileName = image.FileName; // Assumes no path information, just the file name
var ext = fileName.Substring(fileName.LastIndexOf('.') + 1).ToLower();
if (!UmbracoConfig.For.UmbracoSettings().Content.DisallowedUploadFiles.Contains(ext))
{
var mediaType = Constants.Conventions.MediaTypes.File;
if (UmbracoConfig.For.UmbracoSettings().Content.ImageFileTypes.Contains(ext))
mediaType = Constants.Conventions.MediaTypes.Image;
var f = mediaService.CreateMedia(fileName, mediaRootId, mediaType);
// Assumes the image._Image is a Stream - you may have to do some extra work here...
f.SetValue(Constants.Conventions.Media.File, fileName, (Stream)image._Image); // Real magic happens here.
mediaService.Save(f);
imageIds += (imageIds.Length > 0 ? "," : "") + f.Id;
}
}
// Get the relevant property on the new item and save the image list to it.
var imagesProp = item.Properties.Where(p => p.Alias == "productImages").FirstOrDefault();
imagesProp.Value = imageIds;
Note - I haven't tested this code out, so ymmv.
