在Web Api中集成protobuf

1. 安装WebApiContrib.Formatting.ProtoBuf

   1. Install-Package WebApiContrib.Formatting.ProtoBuf

2. 注册ProtoBufFormatter

   1. public static class WebApiConfig
          {
              public static void Register(HttpConfiguration config)
              {
                  config.Formatters.Add(new ProtoBufFormatter());
                  // Web API configuration and services
      
                  // Web API routes
                  config.MapHttpAttributeRoutes();
      
                  config.Routes.MapHttpRoute(
                      name: "DefaultApi",
                      routeTemplate: "api/{controller}/{id}",
                      defaults: new { id = RouteParameter.Optional }
                  );
              }
          }
      

3. 设置DTO

   1. 注意这里的Order是必须的

   2.  [DataContract]
          public class Item
          {
              [DataMember(Order = 1)]
              public int Id { get; set; }
              [DataMember(Order = 2)]
              public string Name { get; set; }
              [DataMember(Order = 3)]
              public long Value { get; set; }
          }
      

4. 客户端调用

      static  void Main(string[] args)
        {

            var httpClient = new HttpClient();

            httpClient.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/x-protobuf"));

            var response = httpClient.GetAsync("http://localhost:60339/api/Default/GetItem").Result;
            //把 ProtoBuf Stream 反序列化成 集合
            var  obj = (RuntimeTypeModel.Default).Deserialize(response.Content.ReadAsStreamAsync().Result, null, typeof(List<Item>)) as List<Item>;

            Console.WriteLine(obj.Count);

            //设置请求头
            var content = new ObjectContent<List<Item>>(obj, new ProtoBufFormatter());
            content.Headers.ContentType = new MediaTypeHeaderValue("application/x-protobuf");

            var postResponse1=  httpClient.PostAsync("http://localhost:60339/api/Default/PostItem", content).Result;
            var postResult = postResponse1.Content.ReadAsStreamAsync().Result;
            var intValue = (RuntimeTypeModel.Default).Deserialize(postResult, null, typeof(int));

            Console.WriteLine(intValue);
            Console.ReadKey();
        }

使用Fiddler发送Accept 分别为Json,Xml,Protobuf三种格式来请求数据
