ajax请求基于restFul的WebApi(post、get、delete、put)

restFul是符合rest架构风格的网络API接口。

rest是一种软件架构的编码风格,是根据网络应用而去设计和开发的一种可以降低开发复杂度的编码方式,并且可以提高程序的可伸缩性(增减问题)。

几种较为常见的操作类型：get(查询)、post(新增)、put(修改)、delete(删除)

 

2.restFul标准的WebApi搭建以及部署在iis上

在这里为了方便，使用的ef框架，在创建读/写控制器时直接引用了模型类

 

 

控制器直接帮我帮crud的方法都写好了，按照注释的请求规则，可直接使用。代码如下：

using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Data.Entity.Infrastructure;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using System.Web.Http.Description;
using webapi;

namespace webapi.Controllers
{
    public class ProductsController : ApiController
    {
        private DtoolsEntities db = new DtoolsEntities();

        // GET: api/Products
        [HttpGet]
        public IQueryable<Product> GetProduct()
        {
            return db.Product.OrderByDescending(p => p.AddDate).Take(10);
        }

        // GET: api/Products/5
        [HttpGet]
        [ResponseType(typeof(Product))]
        public IHttpActionResult GetProduct(int id)
        {
            Product product = db.Product.Find(id);
            if (product == null)
            {
                return NotFound();
            }

            return Ok(product);
        }

        // PUT: api/Products/5  update
        [HttpPut]
        [ResponseType(typeof(void))]
        public IHttpActionResult PutProduct(int id, Product product)
        {
            if (!ModelState.IsValid)
            {
                return BadRequest(ModelState);
            }

            if (id != product.Id)
            {
                return BadRequest();
            }
            product.AddDate = DateTime.Now;
            db.Entry(product).State = EntityState.Modified;

            try
            {
                db.SaveChanges();
            }
            catch (DbUpdateConcurrencyException)
            {
                if (!ProductExists(id))
                {
                    return NotFound();
                }
                else
                {
                    throw;
                }
            }

            return StatusCode(HttpStatusCode.NoContent);
        }


        // POST: api/Products  
        [HttpPost]
        [ResponseType(typeof(Product))]
        public IHttpActionResult PostProduct(Product product)
        {
            if (!ModelState.IsValid)
            {
                return BadRequest(ModelState);
            }
            product.AddDate = DateTime.Now;
            db.Product.Add(product);
            db.SaveChanges();

            return CreatedAtRoute("DefaultApi", new { id = product.Id }, product);
        }

        // DELETE: api/Products/5  
        [HttpDelete]
        [ResponseType(typeof(Product))]
        public IHttpActionResult DeleteProduct(int id)
        {
            Product product = db.Product.Find(id);
            if (product == null)
            {
                return NotFound();
            }

            db.Product.Remove(product);
            db.SaveChanges();

            return Ok(product);
        }

        protected override void Dispose(bool disposing)
        {
            if (disposing)
            {
                db.Dispose();
            }
            base.Dispose(disposing);
        }

        private bool ProductExists(int id)
        {
            return db.Product.Count(e => e.Id == id) > 0;
        }
    }
}
