How do i do the following with AuthenticationHeaderValue class?

So i basically wanna auth to github api with the basic authentication the string i'm inputing is actually user:token, but it won't work either, here is what i tried so far.

requestClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.ASCII.GetBytes(Client.Env["GITCREDS"])));

requestClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.ASCII.GetBytes(Client.Env["GITCREDS"])));

Client.Env["GITCREDS"] actually returns the string.

i always get 403 because for some reason i'm not able to auth, i want to remark that with insomnia these creds work

@Memw Have you tried breaking it down into steps and see what fails rather than embedding 3 method calls and an indexer?

memwOP•3y ago

yeah i logged Convert.ToBase64String(thing) before and it gave a weird string, i'm guessing comming from Encoding.ASCII.GetBytes()

Yawnder•3y ago

@Memw And when you compared that value from the one shows encoded in the tool you took the screenshot from?

memwOP•3y ago

What do you mean by comparing? it is different that's all i know

Yawnder•3y ago

Well you don't see keen on sharing any details so good luck!

memwOP•3y ago

i do but what details do you want me to share i didn't understand the question correctly, i'm not native english, so sorry for that

Yawnder•3y ago

Alright. Since you shouldn't share a password, try with username abc and password def1%& and give the values of when extracted from the setting and when encoded. I'll compare to what I have on my side.

memwOP•3y ago

With this input

Encoding.ASCII.GetBytes("abc:def1%&")

Encoding.ASCII.GetBytes("abc:def1%&")

The output is YWJjOmRlZjElJg== @Yawnder

Yawnder•3y ago

Same value as I have...

memwOP•3y ago

i'm actually doing this

requestClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.ASCII.GetBytes("abc:def1%&")));
        Console.WriteLine(requestClient.DefaultRequestHeaders.Authorization.Parameter);

requestClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.ASCII.GetBytes("abc:def1%&")));
        Console.WriteLine(requestClient.DefaultRequestHeaders.Authorization.Parameter);

requestClient being an HttpClient

Yawnder•3y ago

Are you certain your Client.Env["GITCREDS"] returns the proper value?

memwOP•3y ago

i logged it and yeah i'm pretty sure it does

Yawnder•3y ago

Humn...

memwOP•3y ago

i can't share the full thing but yeah it does log the thing and the thing is always

Exception: Response status code does not indicate success: 403 (Forbidden).

Exception: Response status code does not indicate success: 403 (Forbidden).

as if there were no credentials or something

Yawnder•3y ago

Could that be it?

Yawnder•3y ago

Wait, 403 isn't that actually

memwOP•3y ago

I'm using username and token

Yawnder•3y ago

403 means the authentication is working fine, but authorization isn't.

memwOP•3y ago

and with insomnia http client it just gives me 200

Yawnder•3y ago

For the same endpoint?

memwOP•3y ago

yup maybe the way is not user:token? and other thing? or github doesn't want base64? but with raw string doesn't let me either so i'm kinda lost on that

Yawnder•3y ago

No idea. If it works with insomnia, you could inspect using Fiddler and see what is different.

memwOP•3y ago

Oh.

User Agent

Yawnder•3y ago

But why does the same credentials work for the same endpoint using another client?

memwOP•3y ago

Because insomnia maybe sends the user agent, i'm not sure what does it send but i'm very sure it does send the user agent

Yawnder•3y ago

Oh! Weird that it's not stated obviously in the doc since it's atypical.

memwOP•3y ago

imma see if all of this user agent thingy works

Yawnder•3y ago

https://docs.github.com/en/rest/overview/resources-in-the-rest-api#user-agent-required It's just not in the "Other Authentication" page.

memwOP•3y ago

it was that damn i just

requestClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.ASCII.GetBytes(Client.Env["GITCREDS"])));
requestClient.DefaultRequestHeaders.UserAgent.Add(new ProductInfoHeaderValue("JamieWorshipper", "1.0"));
requestClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

requestClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.ASCII.GetBytes(Client.Env["GITCREDS"])));
requestClient.DefaultRequestHeaders.UserAgent.Add(new ProductInfoHeaderValue("JamieWorshipper", "1.0"));
requestClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

Yawnder•3y ago

Good then!

memwOP•3y ago

thanks a lot and sorry for the missunderstanding before

Yawnder•3y ago

Don't worry. I have a short temper when I'm tired. I should go to bed 😉
