RestSharp 使用默认值反序列化对 object 的 401 响应

Question

I've experienced an issue while using RestSharp.

I have a method in my client which is show below. When I send a request with a valid token I get an IEnumerable of type StravaActivityDto , and its working fine. But when I send a request and my token is not valid, instead of activities variable being null it is IEnumerable of type StravaActivityDto , but it always has only one object in it and this has a default value in every property (eg Id =0, MaxSpeed =0).

I have checked the behavior in Postman and if I make a request with an invalid token the status code of the response is 401.

How can I stop RestSharp from deserializing the response if the request is invalid (which results in creating StravaActivityDto with default values).
I know I can use request.Execute and then check IsSuccessful status but I would like to just get null after calling request.Get<>() .

public async Task<IEnumerable<StravaActivityDto>> GetActivities(string token)
{
    var request = new RestRequest("activities", DataFormat.Json);
    request.AddHeader("authorization", "Bearer " + token);
    var activities = await RestClient.GetAsync<IEnumerable<StravaActivityDto>>(request);

    return activities;
}

Answer 1

This is default behavior of RestSharp, it didn't throw any errors on responses with HTTP errors, only on transport level (when server is unreachable or etc)

So you have 2 options:

First

Add OnBeforeDeserialization on every request

request.OnBeforeDeserialization = response =>
{
     if (!response.IsSuccessful)
          throw new Exception("Response is unsuccessful");
};

Second

Use ExecuteGetAsync instead of GetAsync method and check for errors on every response.

var response = await client.ExecuteGetAsync<IEnumerable<StravaActivityDto>>(request);
                
if (!response.IsSuccessful)
    throw new Exception("Response is unsuccessful");

return response.Data;

also instead of using

request.AddHeader("authorization", "Bearer " + token);

on every requests, you can use JwtAuthenticator (or your custom authenticator if you want) once in client initialization.

var client = new RestClient()
{
    Authenticator = new JwtAuthenticator("MyBearerToken")
};
