c# - 如何使用路由属性绑定(bind) WebAPI GET 请求中的请求模型？

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。

我的问题是是否可以在 GET 请求中绑定(bind)请求模型？

例如我有这样一个请求模型

 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 get 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，但每次我在我的书中得到 null (BookRequestModel)

Answer 1

添加 [FromUri] 然后重试如下

[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};
            }
