WCF Resful Service

[ServiceContract]
public interface IBookService
{
    [OperationContract]
    [WebGet]
    List<Book> GetBooksList();

    [OperationContract]
    [WebGet(UriTemplate  = "Book/{id}")]
    Book GetBookById(string id);

    [OperationContract]
    [WebInvoke(UriTemplate = "AddBook/{name}")]
    void AddBook(string name);

    [OperationContract]
    [WebInvoke(UriTemplate = "UpdateBook/{id}/{name}")]
    void UpdateBook(string id, string name);

    [OperationContract]
    [WebInvoke(UriTemplate = "DeleteBook/{id}")]
    void DeleteBook(string id);
}

实施服务

现在，服务实现部分将使用实体框架生成的上下文和实体来执行所有相应的操作。

public class BookService : IBookService
{
    public List<Book> GetBooksList()
    {
        using (SampleDbEntities entities = new SampleDbEntities())
        {
            return entities.Books.ToList();
        }
    }

    public Book GetBookById(string id)
    {
        try
        {
            int bookId = Convert.ToInt32(id);

            using (SampleDbEntities entities = new SampleDbEntities())
            {
                return entities.Books.SingleOrDefault(book => book.ID == bookId);
            }
        }
        catch
        {
            throw new FaultException("Something went wrong");
        }
    }

    public void AddBook(string name)
    {
        using (SampleDbEntities entities = new SampleDbEntities())
        {
            Book book = new Book { BookName = name };
            entities.Books.AddObject(book);
            entities.SaveChanges();
        }
    }

    public void UpdateBook(string id, string name)
    {
        try
        {
            int bookId = Convert.ToInt32(id);

            using (SampleDbEntities entities = new SampleDbEntities())
            {
                Book book = entities.Books.SingleOrDefault(b => b.ID == bookId);
                book.BookName = name;
                entities.SaveChanges();
            }
        }
        catch
        {
            throw new FaultException("Something went wrong");
        }
    }

    public void DeleteBook(string id)
    {
        try
        {
            int bookId = Convert.ToInt32(id);

            using (SampleDbEntities entities = new SampleDbEntities())
            {
                Book book = entities.Books.SingleOrDefault(b => b.ID == bookId);
                entities.Books.DeleteObject(book);
                entities.SaveChanges();
            }
        }
        catch
        {
            throw new FaultException("Something went wrong");
        }
    }
}

Restful WCF 服务配置

现在从 ServiceContract 透视图中，服务已准备好为 REST 请求提供服务，但是为了在休息时访问此服务，我们还需要对服务行为和绑定进行一些更改。

要使服务通过 REST 协议可用，需要使用的绑定是 webHttpBinding。此外，我们需要设置端点的行为配置并在 endpointBehavior 中定义 webHttp 参数。所以我们的结果配置如下：
