指定调用Web Api 2 Controller方法的正确路由

Question

我创建了一个PublicController.cs，它将返回代理列表。然后我构建并运行项目并打开Postman更改模式以获取并调用http://localhost:50159/api/public/Agents我得到的消息是

{
    "Message": "No HTTP resource was found that matches the request URI 'http://localhost:50159/api/public/Agents'.",
    "MessageDetail": "No action was found on the controller 'Public' that matches the request."
}

有什么我想念的吗？

    [HttpGet]
    public IHttpActionResult Agents(string key, string diseaseId)
    {
        GuardKey(key);

        var result = AgentsDataService.GetAgents();



        return Json(result);
    }
