Making a windows phone application and although I may easily pull from my Web Api I am having trouble posting to it. Whenever posting to the api I get the "Unsupported Media Type" error message and I'm not sure as to why it is happening considering the class I using as the base for my JSON post is the same as the one used in the api.
PostQuote (Post Method)
private async void PostQuote(object sender, RoutedEventArgs e)
{
Quotes postquote = new Quotes(){
QuoteId = currentcount,
QuoteText = Quote_Text.Text,
QuoteAuthor = Quote_Author.Text,
TopicId = 1019
};
string json = JsonConvert.SerializeObject(postquote);
if (Quote_Text.Text != "" && Quote_Author.Text != ""){
using (HttpClient hc = new HttpClient())
{
hc.BaseAddress = new Uri("http://rippahquotes.azurewebsites.net/api/QuotesApi");
hc.DefaultRequestHeaders.Accept.Clear();
hc.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = await hc.PostAsync(hc.BaseAddress, new StringContent(json));
if (response.IsSuccessStatusCode)
{
Frame.Navigate(typeof(MainPage));
}
else
{
Quote_Text.Text = response.StatusCode.ToString();
//Returning Unsupported Media Type//
}
}
}
}
Quotes and Topic (Model)
public class Quotes
{
public int QuoteId { get; set; }
public int TopicId { get; set; }
public string QuoteText { get; set; }
public string QuoteAuthor { get; set; }
public Topic Topic { get; set; }
public string QuoteEffect { get; set; }
}
//Topic Model//
public class Topic
{
public int TopicId { get; set; }
public string TopicName { get; set; }
public string TopicDescription { get; set; }
public int TopicAmount { get; set; }
}
I found this question while working on a quick and dirty reverse proxy. I needed form data and not JSON.
This did the trick for me.
string formData = "Data=SomeQueryString&Foo=Bar";
var result = webClient.PostAsync("http://XXX/api/XXX",
new StringContent(formData, Encoding.UTF8, "application/x-www-form-urlencoded")).Result;
To fix the unsupported media type I had to use HttpRequestMessage and add header to accept json with MediaTypeWithQualityHeaderValue like bellow.
var httpRequestMessage = new HttpRequestMessage
{
Content = new StringContent(json, Encoding.UTF8, "application/json")
};
httpRequestMessage.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var httpResponse = await _client.PostAsync("/contacts", httpRequestMessage.Content);
You should set the media type when creating StringContent
new StringContent(json, Encoding.UTF32, "application/json");
