Adding authorization to the headers

Question

I have the following code:

...
AuthenticationHeaderValue authHeaders = new AuthenticationHeaderValue(\"OAuth2\", Contract.AccessToken);
string result = await         


        

Answer 1

I struggled with this. I kept getting an error saying "invalid format" because I have a custom implementation and the Authorization header is validated against certain standards. Adding the header this way however worked:

var http = new HttpClient();
http.DefaultRequestHeaders.TryAddWithoutValidation("Authorization", "key=XXX");
