WebAPI：如何为Post，Put和Delete动词执行属性路由

Question

我是WebAPI的新手。不知何故，我设法为获取类型请求执行属性路由，但不知道如何为Post，Put和Delete动词执行此操作

请参阅我的示例代码并附带经过修改的代码，其中有人会向我展示如何为Post，Put和Delete动词执行属性路由。

[RoutePrefix("api/customer")]
public class CustomerController : ApiController
{
    static readonly ICustomerRepository repository = new CustomerRepository();

    [HttpGet, Route("GetAll")]
    public IEnumerable<Customer> GetAllCustomers()
    {
        return repository.GetAll();
    }

    [HttpGet, Route("GetByID/{customerID}")]
    public Customer GetCustomer(string customerID)
    {
        Customer customer = repository.Get(customerID);
        if (customer == null)
        {
            throw new HttpResponseException(HttpStatusCode.NotFound);
        }
        return customer;
    }

    [HttpGet, Route("GetByCountryName/{country}")]
    public IEnumerable<Customer> GetCustomersByCountry(string country)
    {
        return repository.GetAll().Where(
            c => string.Equals(c.Country, country, StringComparison.OrdinalIgnoreCase));
    }

    public HttpResponseMessage PostCustomer(Customer customer)
    {
        customer = repository.Add(customer);
        var response = Request.CreateResponse<Customer>(HttpStatusCode.Created, customer);

        string uri = Url.Link("DefaultApi", new { customerID = customer.CustomerID });
        response.Headers.Location = new Uri(uri);
        return response;
    }

    public void PutProduct(string customerID, Customer customer)
    {
        customer.CustomerID = customerID;
        if (!repository.Update(customer))
        {
            throw new HttpResponseException(HttpStatusCode.NotFound);
        }
    }

    public void DeleteProduct(string customerID)
    {
        Customer customer = repository.Get(customerID);
        if (customer == null)
        {
            throw new HttpResponseException(HttpStatusCode.NotFound);
        }
        repository.Remove(customerID);
    }
}

客户类

public class Customer
{
    public string CustomerID { get; set; }
    public string CompanyName { get; set; }
    public string ContactName { get; set; }
    public string ContactTitle { get; set; }

    public string Address { get; set; }

    public string Region { get; set; }

    public string PostalCode { get; set; }
    public string City { get; set; }
    public string Country { get; set; }
    public string Phone { get; set; }
    public string Fax { get; set; }
}

不是测试，但我认为它应该是这样的：

[RoutePrefix("api/customer")]
public class CustomerController : ApiController
{
    static readonly ICustomerRepository repository = new CustomerRepository();

    [HttpGet]
    [Route("")]
    public IEnumerable<Customer> GetAllCustomers()
    {
        return repository.GetAll();
    }

    [HttpGet]
    [Route("{customerID}")]
    public Customer GetCustomer(string customerID)
    {
        Customer customer = repository.Get(customerID);
        if (customer == null)
        {
            throw new HttpResponseException(HttpStatusCode.NotFound);
        }
        return customer;
    }

    [HttpGet]
    [Route("/GetByCountryName/{country}")]
    public IEnumerable<Customer> GetCustomersByCountry(string country)
    {
        return repository.GetAll().Where(
            c => string.Equals(c.Country, country, StringComparison.OrdinalIgnoreCase));
    }

    [HttpPost]
    [Route("")]
    public HttpResponseMessage PostCustomer([FromBody]Customer customer)
    {
        customer = repository.Add(customer);
        var response = Request.CreateResponse<Customer>(HttpStatusCode.Created, customer);

        string uri = Url.Link("DefaultApi", new { customerID = customer.CustomerID });
        response.Headers.Location = new Uri(uri);
        return response;
    }

    [HttpPut]
    [Route("{customerID}")]
    public void PutProduct(string customerID, [FromBody]Customer customer)
    {
        customer.CustomerID = customerID;
        if (!repository.Update(customer))
        {
            throw new HttpResponseException(HttpStatusCode.NotFound);
        }
    }

    [HttpDelete]
    [Route("{customerID}")]
    public void DeleteProduct(string customerID)
    {
        Customer customer = repository.Get(customerID);
        if (customer == null)
        {
            throw new HttpResponseException(HttpStatusCode.NotFound);
        }
        repository.Remove(customerID);
    }
}
