如何更改 ServiceStack 中的 HTTP 401 响应? [英] How to change HTTP 401 response in ServiceStack?

问题描述

默认情况下，当我在授权前尝试调用任何内容时，ServiceStack 返回 http 状态 401.我如何返回 http 状态 200 和我的 DTO 而不是那个?

By default, ServiceStack returns http status 401 when I try to call anything before authorization. How do I return http status 200 and my DTO instead of that?

理想情况下，如果我尝试调用任何未经授权的内容，我想在 ResponseStatus 应用程序范围内显示 boolean NeedAuth=true 标志.

Ideally, I want to show boolean NeedAuth=true flag in ResponseStatus application wide, if I try calling anything unauthorized.

推荐答案

我修改了我之前创建的自定义 AuthProvider.现在，如果我在身份验证之前调用任何内容或尝试提供错误的凭据，我会得到 HTTP 200 OK 状态和此响应:

I've modified my previously created custom AuthProvider. Now if I call anything before authentication or try to provide wrong credentials, I get HTTP 200 OK status and this response:

{
    "NeedAuth": true
}

我扩展了 AuthResponse:

I've extended AuthResponse:

public class MyAuthResponse : AuthResponse
{
    public bool? NeedAuth { get; set; }
}

并修改了我从 CredentialsAuthProvider 继承的自定义 AuthProvider:

And modified my custom AuthProvider inherited from CredentialsAuthProvider:

// This one is called when I call anything before authorization
public override void OnFailedAuthentication(IAuthSession session, ServiceStack.ServiceHost.IHttpRequest httpReq, ServiceStack.ServiceHost.IHttpResponse httpRes)
{
    httpRes.StatusCode = (int)HttpStatusCode.OK;
    var callback = httpReq.GetJsonpCallback();
    var doJsonp = EndpointHost.Config.AllowJsonpRequests && !string.IsNullOrEmpty(callback);
    var res = new MyAuthResponse() { NeedAuth = true };
    if (doJsonp)
        httpRes.WriteToResponse(httpReq, res, (callback + "(").ToUtf8Bytes(), ")".ToUtf8Bytes());
    else
        httpRes.WriteToResponse(httpReq, res);
}

// This one is called when I try to login
public override object Authenticate(IServiceBase authService, IAuthSession session, Auth request)
{
    var userName = request.UserName;
    var password = request.Password;
    var res = new MyAuthResponse();

    if (!LoginMatchesSession(session, userName))
    {
        authService.RemoveSession();
        session = authService.GetSession();
    }

    if (TryAuthenticate(authService, userName, password))
    {
        if (session.UserAuthName == null)
            session.UserAuthName = userName;

        OnAuthenticated(authService, session, null, null);

        res.UserName = userName;
        res.SessionId = session.Id;
    }
    else
        res.NeedAuth = true;

    return res;
}
