Question

我在使用WCF REST解析请求主体方面遇到了困难。我的问题：

POST方法https：// {服务} / X / Y？ Z = 0000000
正文请求：{＆＃34; id＆＃34;：＆＃34; id＆＃34;}

我的代码：

[ServiceContract]
public interface IService
{
    [OperationContract]
    [WebInvoke(Method = "POST",
                BodyStyle = WebMessageBodyStyle.Bare,
                RequestFormat = WebMessageFormat.Json,
                ResponseFormat = WebMessageFormat.Json,
                UriTemplate = "/X/{y}?Z={z}")
                ]
    string GetRequest(string y, string z, Request request);
}

public class Service : IService
{
    public string GetRequest(string y, string z, Request request)
    {
        //Do sth
    }


[DataContract]
public class Request
{
    [DataMember]
    [JsonProperty("id")]
    public String  Id { get; set; }
}

我遇到的问题是y和z有数据并且它们是正确的但是请求中的 id为null。我希望是＆＃34; id＆＃34;。

我在互联网上搜索了很多，我找到了Stream解决方案，在这种情况下不容易遵循。我想知道是否有人有一个聪明的想法来做到这一点。

看看这个版本

服务

namespace ServiceTest
{
    internal class Program
    {
        private static WebServiceHost _service;

        private static void Main()
        {
            _service = new WebServiceHost(typeof (Service));
            Console.WriteLine("The service has started");
            _service.Open();
            Console.ReadKey();
        }
    }

    [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
    public sealed class Service : IService
    {
        public string GetRequest(string y, string z, Request request)
        {
            Console.WriteLine("Y: {0}, Z: {1}, request: {2}", y, z, request);
            return "Ok";
        }
    }

    [ServiceContract]
    public interface IService
    {
        [OperationContract]
        [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, RequestFormat = WebMessageFormat.Json,
            ResponseFormat = WebMessageFormat.Json, UriTemplate = "/X/{y}?Z={z}")]
        string GetRequest(string y, string z, Request request);
    }

    [DataContract]
    public sealed class Request
    {
        [DataMember]
        public string Id { get; set; }

        public override string ToString()
        {
            return string.Format("Id: {0}", Id);
        }
    }
}

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

    <system.serviceModel>
        <services>
            <service name="ServiceTest.Service">
                <host>
                    <baseAddresses>
                        <add baseAddress="http://localhost:9090/webhost" />
                    </baseAddresses>
                </host>
                <endpoint binding="webHttpBinding" contract="ServiceTest.IService" />
            </service>
        </services>
    </system.serviceModel>

    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
</configuration>

客户

internal class Program
{
    private static void Main(string[] args)
    {
        var client = new HttpClient();
        var request = new Request {Id = "Nelibur"};
        var result = client.PostAsync("http://localhost:9090/webhost/X/Y?Z=2000", CreateContent(request)).Result;
        Console.WriteLine(result.Content.ReadAsStringAsync().Result);
        Console.ReadKey();
    }

    private static StringContent CreateContent<T>(T value)
    {
        using (var stream = new MemoryStream())
        {
            var serializer = new DataContractJsonSerializer(typeof (T));
            serializer.WriteObject(stream, value);
            string content = Encoding.UTF8.GetString(stream.ToArray());
            return new StringContent(content, Encoding.UTF8, "application/json");
        }
    }
}

原始请求：

POST http://localhost:9090/webhost/X/Y?Z=2000 HTTP/1.1
Content-Type: application/json; charset=utf-8
Host: localhost:9090
Content-Length: 16
Expect: 100-continue
Connection: Keep-Alive

{"Id":"Nelibur"}

您可以尝试使用请求，例如Fiddler
