Asset addition using web api c#


Level 1

I am at present writing some tests for Azure Experience Manager ,in which i need to upload huge data like jpg , Tiff ,Zip .. etc files.

So To add that I am using Api POST call using my C# Test Project in visual Studio  .

I am using Http Client with HttpContent as MultipartFormDataContent , so it adds the Asset inside my Custom Folder in CRXDE Lite

the Url is Like this "http://localhost:4502/crx/de/index.jsp#/content/dam/AemTest ".

But the Structure it shows is, it add a FileContent e.g abc.jpg and child Node it adds jcr:content where some metadata appears . Inside Tool-> CRXDE lite

Note : jcr:primaryType =  nt:file

But when Looked inside Assets Folder , it shows Empty . i.e Navigation->Asset-> Files->AemTest

Now when I am Tring to add Manually the Same Asset

it shows an Asset added as  jcr:primaryType = dam:Asset inside CRXDE Lite

also the Structure it comes as first it creates a Node Named  eg. "abc.jpg" then in child Node jcr:content then child node metadata, rendition folder, related node

How can I achieve this by using Api calls like POST,GET ,PUT .

Referring to document , Now I am Trying to Update the Metadata for a Asset e.g bird.jpg

So Below is the Code I am Referring to

HttpWebRequest httpWReq = (HttpWebRequest)WebRequest.Create(http://localhost:4502/content/AemTest/bird.jpg);

NetworkCredential nc = new NetworkCredential("admin", "admin");

         httpWReq.Method = "PUT";

        httpWReq.Credentials = nc;

        httpWReq.ContentType = "application/json";

        String postData = "{\"class\":\"asset\", \"properties\":{\"dc:title\":\"My Asset\"}}";

            using (var streamWriter = new StreamWriter(httpWReq.GetRequestStream()))






HttpWebResponse response = (HttpWebResponse)httpWReq.GetResponse();

But everytime it returns "NO CONTENT". and the Asset is not getting updated .
