My .net 4.0 class library send HttpRequestMessage and receive HttpResponseMessage from .asp Web API (REST).
When I sent a small class, I use JSON to parse it as string, then I send string by:
request = new HttpRequestMessage();
request.RequestUri = new Uri(myRestAPI);
request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
request.Method = method;
if (method != HttpMethod.Get)
request.Content = new StringContent(content, Encoding.UTF8, mthv);
Next, use HttpClient to send it:
using (HttpResponseMessage httpResponse = _client.SendAsync(request).Result)
{..}
This works fine.
Now, my class has got bigger, How can i send it ?
What i did was to zip it and send as ByteArrayContent.
request = new HttpRequestMessage();
request.RequestUri = new Uri(url);
request.Method = method;
if (method != HttpMethod.Get)
request.Content = new ByteArrayContent(content);
request.Content.Headers.ContentType = new MediaTypeHeaderValue("multipart/form-data");
And send it the same way.
But now the server does reply me with error:
No MediaTypeFormatter is available to read an object of type 'Byte[]' from content with media type 'multipart/form-data'.
What am I doing wrong ?? I am trying to find a proper guide and all the guides are talking about uploading FROM web api and not about uploading from application to web api..
application/octet-stream. If you really wanted to send multipart form data then you would use the MultiPartFormDataContent class. Either way, you shouldn't be changing the content-type just because you want to compress. That's why there is a separate content-encoding header. – Darrel Miller
