有谁知道VS 2010中是否有HttpClient和HttpResponseMessage类？我似乎无法让它们工作,我是否需要添加引用或使用命名空间？

这些类最初来自REST for Vs 2008的入门套件......在vs 2010中它的内置即没有用于入门套件......

但如果缺少这些类,我该如何使用它们...

我搜索了谷歌的答案,我一直在寻找的是vs 2008的示例,即REST入门套件.

任何帮助真的很感激

提前致谢

我很困惑你何时以及为什么要在REST中使用特定的动词？

我知道基本的东西,比如:

Get -> for retrieval
Post -> adding new entity
PUT -> updating
Delete -> for deleting

这些属性是按照我上面写的操作使用的,但我不明白为什么？如果在REST中的Get方法内部我会添加一个新实体或在POST内部更新一个实体会发生什么？或者可能在DELETE里面我添加一个实体.我知道这可能是一个noob问题,但我需要了解它.这对我来说听起来很混乱.

我的WCF服务中有以下方法:

[OperationContract]
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Xml, RequestFormat = WebMessageFormat.Xml)]
public int GetOne(string param1, string param2)
{
    return 1;
}

我从Flex应用程序发送xml,它需要一个如下所示的对象:{ param1: "test", param2: "test2" }并将其转换为以下请求:

POST http://localhost:8012/MyService.svc/GetOne HTTP/1.1
Accept: application/xml
Accept-Language: en-US
x-flash-version: 10,1,53,64
Content-Type: application/xml
Content-Length: 52
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)
Host: localhost:8012
Connection: Keep-Alive
Pragma: no-cache
Cookie: ASP.NET_SessionId=drsynacw0ignepk4ya4pou23

<param1>something</param1><param2>something</param2>

我收到了错误The incoming message has an unexpected message format 'Raw'. The expected message …

我的合同细节如下.我正在使用Json响应和请求格式,也使用POST方法.如何编写客户端以在c#中使用此服务.

[OperationContract()]
[WebInvoke(UriTemplate = "/RESTJson_Sample1_Sample1Add", Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
int RESTJson_Sample1_Sample1Add(Int32 a, Int32 b, Int32 c);

我有一个使用.NET 4.0用C#编写的RESTful WCF Web服务,我希望使用GZip或deflate压缩响应.(我可能也需要支持请求压缩,但这还不是必需的).它将作为Windows服务部署,即自托管WCF服务,因为IIS托管不是一个选项.

到目前为止,我的搜索还很短.大多数命中要么是在IIS中打开压缩,要么是为基于SOAP的服务编写自定义消息编码器,既不适合我的场景,也不适合我的场景.

如果您有任何指示如何做到这一点,将不胜感激!

我有那个错误：

合同“IService”中的操作“GetFields”使用具有 SOAP 标头的 MessageContract。None MessageVersion 不支持 SOAP 标头。

问题是我的操作被两个端点使用：CustomEndpoint with messageVersion="Soap12WSAddressing10" 和第二个 webHttpBehavior。

我认为这个错误引发了 Rest 有 MessageVersion.None 的问题

有什么办法解决吗？

我试图实现REST WCF以探索PUT和POST动词之间的区别.我已使用该服务在某个位置上传了一个文件.

服务实现如下:

[OperationContract]
[WebInvoke(UriTemplate = "/UploadFile", Method = "POST")]
void UploadFile(Stream fileContents);

public void UploadFile(Stream fileContents)
{
 byte[] buffer = new byte[32768];
 MemoryStream ms = new MemoryStream();
 int bytesRead, totalBytesRead = 0;
 do
 {
       bytesRead = fileContents.Read(buffer, 0, buffer.Length);
       totalBytesRead += bytesRead;

       ms.Write(buffer, 0, bytesRead);
  } while (bytesRead > 0);

  using (FileStream fs = File.OpenWrite(@"C:\temp\test.txt")) 
  { 
      ms.WriteTo(fs); 
   }

  ms.Close();

}

客户端代码如下:

HttpWebRequest request =     (HttpWebRequest)HttpWebRequest.Create("http://localhost:1922   /EMPRESTService.svc/UploadFile");
        request.Method = "POST";
        request.ContentType = "text/plain";

        byte[] fileToSend = File.ReadAllBytes(@"C:\TEMP\log.txt");  // txtFileName contains …

我在我的WCF服务中使用基本身份验证.并且还使用ASP Membership provider进行身份验证.

Web.Config: 对于REST服务:

<webHttpBinding>
    <binding name="webHttpBinding" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="200065536" maxBufferPoolSize="200065536" maxReceivedMessageSize="200065536"   transferMode="Buffered" useDefaultWebProxy="true">
      <readerQuotas maxDepth="202048000" maxStringContentLength="202048000" maxArrayLength="202048000"
                    maxBytesPerRead="202048000" maxNameTableCharCount="202048000"/>
      <security mode="Transport">  
      </security>
    </binding>
  </webHttpBinding>

验证类型和模式:

<serviceCredentials>
            <userNameAuthentication userNamePasswordValidationMode="MembershipProvider" membershipProviderName="CustomMemberShipProvider" />
</serviceCredentials>

在调用任何方法之前,我的BasicAuthentication类.代码如下所示:

namespace BasicAuth.Service
{
    public class BasicAuthenticationInvoker : Attribute, IOperationBehavior, IOperationInvoker
    {
        #region Private Fields

        private IOperationInvoker _invoker;

        #endregion Private Fields

        #region IOperationBehavior Members

        public void ApplyDispatchBehavior(OperationDescription operationDescription,
                                          DispatchOperation dispatchOperation)
        {
            _invoker = dispatchOperation.Invoker;
            dispatchOperation.Invoker = this;
        }

        public void ApplyClientBehavior(OperationDescription operationDescription, …

我在IIS中托管了WCF 4.5 Restful服务,我正在尝试使用RemoteEndpointMessageProperty来获取使用该服务的客户端的IP地址.

代码1:

private string GetClientIP()
{
  OperationContext context = OperationContext.Current;
  MessageProperties prop = context.IncomingMessageProperties;
  RemoteEndpointMessageProperty endpoint =
         prop[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty;
  string ip = endpoint.Address;
  return ip;
}

代码2:

private string GetClientIP()
{
  string retIp = string.Empty;
  OperationContext context = OperationContext.Current;
  MessageProperties prop = context.IncomingMessageProperties;
  HttpRequestMessageProperty endpointLoadBalancer =
  prop[HttpRequestMessageProperty.Name] as HttpRequestMessageProperty;
  if (endpointLoadBalancer.Headers["X-Forwarded-For"] != null)
  {
    retIp = endpointLoadBalancer.Headers["X-Forwarded-For"];
  }
  if (string.IsNullOrEmpty(retIp))
  {
    RemoteEndpointMessageProperty endpoint =
                prop[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty;
                retIp = endpoint.Address;
  }
  return retIp;
}

但是,由于WCF服务托管在负载均衡器后面的IIS中,因此我获得的IP地址始终是负载均衡器的IP.有没有办法解决这个问题,以便我可以获得客户的真正IP？

谁知道这有什么问题？我无法从我的wcf休息服务获得json响应.

jQuery的

$.ajax({
  type: 'POST',
  url: "http://localhost:8090/UserService/ValidateUser",
  data: {username: 'newuser', password: 'pwd'},
  contentType: "application/json; charset=utf-8",
  success: function(msg) {
   alert(msg);
  },

  error: function(xhr, ajaxOptions, thrownError) {
   alert('error');
  }

});

服务

  [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
    public class UserService: IUserService
    {
        private readonly IUserRepository _repository;

        public UserService()
        {
            _repository = new UserRepository();
