Set HttpClient Authorization Header

Question

I have the following code, and I want to set up mail request authorization this way:

Authorization:key=somevalue

 using (HttpClient client = new HttpClient()) { using (StringContent jsonContent = new StringContent(json)) { jsonContent.Headers.ContentType = new MediaTypeHeaderValue("application/json"); using (HttpResponseMessage response = await client.PostAsync("https://android.googleapis.com/gcm/send", jsonContent)) { var reponseString = await response.Content.ReadAsStringAsync(); } } } 

how to do it? I am really struggling and the following statement

 client.DefaultRequestHeaders.Add("Authorization", "key=" + apiKey); 

the following exception is thrown

An exception of type "System.FormatException" occurred in System.Net.Http.dll, but was not processed in user code

Answer 1

I solved this with the following line of code.

 client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("key", "=" + apiKey);
