如何在具有路由属性的WebAPI GET请求中绑定请求模型？

Question

GET :http://www.Example.com/Api/1/0/Book/Company/0 

[Route("{UserId}/{Category}/books/{BookType}/{Page}")]
        [HttpGet]
        [RequestAuthorization]
         public Response Get(int UserId,string Category, string BookType,int Page )
        {          
            var books= this.contentService.GetUserItems(UserId,Category, BookType, Page)
            return new Response() { Status = ApiStatusCode.Ok, Books = books};
        }

上面的代码对我来说效果很好。

我的问题是可以在GET请求中绑定请求模型吗？

例如我有一个这样的请求模型

 public class BookbRequestModel
    {
        public int UserId { get; set; }
        public int Category { get; set; }
        public int Page { get; set; }  
        public string BookType { get; set; }       
    }

我想要这样的请求

GET :http://www.Example.com/Api/1/0/Book/Company/0 

to bind the data to my request model


[Route("{UserId}/{Category}/books/{BookType}/{Page}")]
        [HttpGet]
        [RequestAuthorization]
         public Response Get(BookbRequestModel book )
        {          
            var books= this.contentService.GetUserItems(book.UserId,book.Category,book.BookType,book.Page)
            return new Response() { Status = ApiStatusCode.Ok, Books = books};
        }

我试过了，但是每次我的书（BookRequestModel）为空时

Answer 1

添加[FromUri]，然后按如下所示重试

[Route("{UserId}/{Category}/books/{BookType}/{Page}")]
            [HttpGet]
            [RequestAuthorization]
             public Response Get(([FromUri] BookbRequestModel book )
            {          
                var books= this.contentService.GetUserItems(book.UserId,book.Category,book.BookType,book.Page)
                return new Response() { Status = ApiStatusCode.Ok, Books = books};
            }

它采用参数，因为它们是您不能执行的操作。 我建议尝试更改routeConfig。 添加新路线。 在WebApiConfig.cs 。

config.Routes.MapHttpRoute(
                name: "NewApiRoute",
                routeTemplate: "myapi/{Controller}/{id}",
                defaults: new { id = new object()//this is to make it generic you can pass object of your class also }
                );
