I'm implementing an API made by other colleagues with Apiary.io, in a Windows Store app project.
They show this example of a method I have to implement:
var baseAddress = new Uri("https://private-a8014-xxxxxx.apiary-mock.com/");
using (var httpClient = new HttpClient{ BaseAddress = baseAddress })
{
using (var response = await httpClient.GetAsync("user/list{?organizationId}"))
{
string responseData = await response.Content.ReadAsStringAsync();
}
}
In this and some other methods, I need to have a header with a token that I get before.
Here's an image of Postman (chrome extension) with the header I'm talking about:
How do I add that Authorization header to the request?
This question is related to

You can add whatever headers you need to the HttpClient
.
Here is a nice tutorial about it.
This doesn't just reference to POST-requests, you can also use it for GET-requests.
Sometimes, you only need this code.
httpClient.DefaultRequestHeaders.Add("token", token);
A later answer, but because no one gave this solution...
If you do not want to set the header on the HttpClient
instance by adding it to the DefaultRequestHeaders
, you could set headers per request.
But you will be obliged to use the SendAsync()
method.
This is the right solution if you want to reuse the HttpClient
-- which is a good practice for
Use it like this:
using (var requestMessage =
new HttpRequestMessage(HttpMethod.Get, "https://your.site.com"))
{
requestMessage.Headers.Authorization =
new AuthenticationHeaderValue("Bearer", your_token);
httpClient.SendAsync(requestMessage);
}
Following the greenhoorn's answer, you can use "Extensions" like this:
public static class HttpClientExtensions
{
public static HttpClient AddTokenToHeader(this HttpClient cl, string token)
{
//int timeoutSec = 90;
//cl.Timeout = new TimeSpan(0, 0, timeoutSec);
string contentType = "application/json";
cl.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(contentType));
cl.DefaultRequestHeaders.Add("Authorization", String.Format("Bearer {0}", token));
var userAgent = "d-fens HttpClient";
cl.DefaultRequestHeaders.Add("User-Agent", userAgent);
return cl;
}
}
And use:
string _tokenUpdated = "TOKEN";
HttpClient _client;
_client.AddTokenToHeader(_tokenUpdated).GetAsync("/api/values")
The accepted answer works but can got complicated when I wanted to try adding Accept headers. This is what I ended up with. It seems simpler to me so I think I'll stick with it in the future:
client.DefaultRequestHeaders.Add("Accept", "application/*+xml;version=5.1");
client.DefaultRequestHeaders.Add("Authorization", "Basic " + authstring);
