在Hangfire中设置JWT承载令牌授权/认证

Question

如何在Hangfire中配置承载令牌授权/认证？

我有一个自定义身份验证筛选器,在初始请求时读取身份验证令牌,但所有其他请求(Hangfire调用)返回401.

如何将Auth Token附加到Hangfire所执行的每个请求的标头中？

如何在令牌过期时刷新令牌？

也许有点晚了，但这是一个可能的解决方案。这个想法来自这篇文章：https://discuss.hangfire.io/t/using-bearer-auth-token/2166

基本思想是将 jwt 添加为查询参数，然后将其收集在 JwtBearerOptions.Events 中，并将 MessageReceivedContext.Token 设置为等于它。这适用于第一个请求，但随后的请求不会附加查询参数，因此我们需要在获取 jwt 时将其添加到 cookie 中。现在我们检查查询参数中的 jwt。如果我们找到它，则将其添加到 cookie 中。如果没有，请在 cookie 中检查。在配置服务中：

services.AddAuthentication(options =>
  {
    options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
    options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;

  })
  .AddJwtBearer((Action<JwtBearerOptions>)(options =>
  {
    options.TokenValidationParameters =
        new TokenValidationParameters
        {
          LifetimeValidator = (before, expires, token, param) =>
                   {
                     return expires > DateTime.UtcNow;
                   },
          IssuerSigningKey = JwtSettings.SecurityKey,
          ValidIssuer = JwtSettings.TOKEN_ISSUER,
          ValidateIssuerSigningKey = true,
          ValidateIssuer = true,
          ValidateAudience = false,
          NameClaimType = GGClaimTypes.NAME
        };

    options.Events = new JwtBearerEvents
    {
      OnMessageReceived = mrCtx =>
      {
        // Look for HangFire stuff
        var path = mrCtx.Request.Path.HasValue ? mrCtx.Request.Path.Value : "";
        var pathBase = mrCtx.Request.PathBase.HasValue ? mrCtx.Request.PathBase.Value : path;
        var isFromHangFire = path.StartsWith(WebsiteConstants.HANG_FIRE_URL) || pathBase.StartsWith(WebsiteConstants.HANG_FIRE_URL);

        //If it's HangFire look for token.
        if (isFromHangFire)
        {
          if (mrCtx.Request.Query.ContainsKey("tkn"))
          {
            //If we find token add it to the response cookies
            mrCtx.Token = mrCtx.Request.Query["tkn"];
            mrCtx.HttpContext.Response.Cookies
            .Append("HangFireCookie",
                mrCtx.Token,
                new CookieOptions()
                {
                  Expires = DateTime.Now.AddMinutes(10)
                });
          }
          else
          {
            //Check if we have a cookie from the previous request.
            var cookies = mrCtx.Request.Cookies;
            if (cookies.ContainsKey("HangFireCookie"))
              mrCtx.Token = cookies["HangFireCookie"];                
          }//Else
        }//If

        return Task.CompletedTask;
      }
    };

  })); 

HangFire 身份验证过滤器：

 public class HangFireAuthorizationFilter : IDashboardAuthorizationFilter
 {

    public bool Authorize(DashboardContext context)
    {
      var httpCtx = context.GetHttpContext();

      // Allow all authenticated users to see the Dashboard.
      return httpCtx.User.Identity.IsAuthenticated;

    }//Authorize

}//Cls
