[Nahush Shrestha]

i am able to post the image and text from postman but i not able to post from Code.

i am able to get the access_token from user. Here is my code look like

  var appUrl = "https://api.tumblr.com/v2/blog/nahushshrestha/post";

            var authzHeader = oauth.GenerateAuthzHeader(appUrl, "POST");

          

            using (HttpClient client = new HttpClient())

            {

                var datas = new Dictionary<string, string>()

                {

                   {"type","photo"},

                   {"source","IMAGEURL"},

                  {"caption","test image api"}

                };

                var data = new FormUrlEncodedContent(datas);

                client.BaseAddress = new Uri(appUrl);

                client.DefaultRequestHeaders.Accept.Clear();

                client.DefaultRequestHeaders.Add("Authorization", authzHeader);

                var Result = await client.PostAsync("", data); /// from this i get the 401 response

                var result=await.client.PostAsync("/?type=photo&source=https://68.media.tumblr.com/fb7e7302e3f34cd6b4e11229ba3fcf5d/tumblr_o8b1oyML9H1riowtoo1_500.jpg&caption=test photo")/// from this i get the 200 response 

          

}

}

Hi Nahush,

I'm sure you've already figured this out, since it's been a long time. But here's what I was thinking, in case anyone else runs into the issue:

For an OAuth-signed request that has a Content-Type of x-www-form-urlencoded, you must include both the query and the body parameters in the signature. From your code sample, it looks like only the query (via `appUri`) is being included in the signature. I'm not sure how your OAuth library functions exactly, but you'll probably need call it with both `appUri` and `data` to generate the Authorization header.
