Using JWT Bearer Authentication When Call API-CodePudding

I want to access an API for a purchased product, I used the following code according to the product documentation:

var client = new RestClient("http://example.com/api/login");

client.Timeout = -1;
var request = new RestRequest(Method.POST);
request.AddParameter("username", "admin");
request.AddParameter("password", "admin");
IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);

The documentation says:

Authentication is performed via JWT Bearer Authentication. Every endpoint requires authentication, so you will need to add the following header to each request

Authorization: Bearer <JWT>

How can I add the JWT authentication in my upper request?

CodePudding user response：

Based on the Access Granted Client Credentials section of the documentation you've provided, the endpoint you need to be calling for a Bearer token is /admin/api/index.php/api/login.

Calling that endpoint with correct credentials will populate your response.Content with the below JSON:

{
  "status": 200,
  "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJodHRwOlwvXC9kZW1vNC5zYXNyYWRpdXMuY29tXC9hZG1pblwvYXBpXC9pbmRleC5waHBcL2FwaVwvbG9naW4iLCJpYXQiOjE2MzA0MDU5OTgsImV4cCI6MTYzMDQwOTU5OCwibmJmIjoxNjMwNDA1OTk4LCJqdGkiOiJCZmdvN00zN2pkbGtRRzFhIiwic3ViIjoxLCJwcnYiOiJkNzk3N2M0N2U5MTY5NjUxMDEwNzM0ZDJmYmY4Y2MxMzlmM2U1MDM0In0.7tNWgF6psOPKpPC9-zU_hEK_GLx3-BeFlIW9LE4wzYo"
}

Deserialise the above JSON object to a token object & the token field will be your JWT token.

Token.cs

public class Token
{
    public int status { get; set; }
    public string token { get; set; }
}

var tokenObj = JsonConvert.DeserializeObject<Token>(response.Content);
string token = tokenObj.token;

For subsequent requests, to authenticate, add this line & you should be good to go.

request.AddHeader("Authorization", $"Bearer {token}");

CodePudding user response：

request.AddHeader("Authorization", $"Bearer {Token}");
