✅ Add OAuth 2.0 in HttpClient Request Headers

Hi folks, I tried to request by Get using HttpClient, but in this case, I don't know how can add this "OAuth 2.0" in HttpClient to send. When I use this code I have the unauthorized 401.

var client = new HttpClient();
var request = new HttpRequestMessage
{
    Method = HttpMethod.Get,
    RequestUri = new Uri("myURL"),
    Headers =
    {
        { "Authorization", "token MyTokenCode" },
    },
};
using (var response = await client.SendAsync(request))
{
    response.EnsureSuccessStatusCode();
    var body = await response.Content.ReadAsStringAsync();
    Console.WriteLine(body);
}

var client = new HttpClient();
var request = new HttpRequestMessage
{
    Method = HttpMethod.Get,
    RequestUri = new Uri("myURL"),
    Headers =
    {
        { "Authorization", "token MyTokenCode" },
    },
};
using (var response = await client.SendAsync(request))
{
    response.EnsureSuccessStatusCode();
    var body = await response.Content.ReadAsStringAsync();
    Console.WriteLine(body);
}

Not sure if I understood you correctly. What do you want to add?

How can I add "OAuth 2.0" in my Get, when I try to request with this code, I have the following unauthorized 401 error. My token is correct, because I tested the request in postman

HimmDawg•6/2/23, 11:58 AM

You mean this?

HimmDawg•6/2/23, 11:59 AM

That's the real token in the picture? You shouldn't post tokens publicly

HHimmDawg That's the real token in the picture? You shouldn't post tokens publicly

Ale KantousianOP•6/2/23, 12:02 PM

No, my real token is another one, I put that one just to illustrate in the image

HimmDawg•6/2/23, 12:02 PM

Good

HHimmDawg ```cs request.Headers.Authorization = new AuthenticationHeaderValue("token", "yo...

I tried this, but I got the same 401

HHimmDawg Good 😄

Ale KantousianOP•6/2/23, 12:33 PM

Sometimes I think this is a bug in .NET

HimmDawg•6/2/23, 12:40 PM

So, when you tried stuff out in postman and it worked there, you could try to copy the headers from postman and add them to your request.

This is my Headers

HimmDawg•6/2/23, 12:42 PM

+7 hidden headers

Ale KantousianOP•6/2/23, 12:43 PM

Hummmmm give me a second

HHimmDawg +7 hidden headers

Ale KantousianOP•6/2/23, 1:11 PM

How can I add this in my headers?

HimmDawg•6/2/23, 1:12 PM

I guess those wont be needed

HHimmDawg I guess those wont be needed

Ale KantousianOP•6/2/23, 1:18 PM

The same again, 401

HimmDawg•6/2/23, 1:22 PM

Hmm, without seeing your code, I'd have to guess from here on. Maybe your url is wrong?

Have you tried using "Bearer" as token prefix?

HimmDawg•6/2/23, 1:41 PM

HHimmDawg ```cs request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", "y...

Ale KantousianOP•6/2/23, 1:43 PM

Yes

HimmDawg•6/2/23, 1:45 PM

I#m running out of ideas here fluffyFoxMood

Is there more to the authorization process? Do you have to provide some client id or so in the url?

HHimmDawg I#m running out of ideas here <:fluffyFoxMood:917843829686693918> Is there more...

Ale KantousianOP•6/2/23, 1:48 PM

Unfortunately not, that's why I told you that I think it's some .NET bugs

HimmDawg•6/2/23, 2:01 PM

That's pretty unlikely imo. But no idea what else could be wrong then

So, yesterday I tried several solutions according to the documentation, according to StackOverFlow and today here with your tips, I find it very difficult for 3 different way to all go wrong when all 3 showed similar or identical solutions.

HimmDawg•6/2/23, 2:24 PM

Must be something super obvious but small then fluffyFoxThink
