Wcf 中的 WebInvoke POST“方法不允许”

Question

我的 Rest wcf 服务如下...

[ServiceContract]
public interface IWinPhoneService
{

[OperationContract]
[WebInvoke(RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "getkpimeasuredata", Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped)]
List<MeasureData> GetKpiMeasureData(DomainData data);


[OperationContract]
[WebGet(UriTemplate = "getdata/{value}", ResponseFormat = WebMessageFormat.Json)]
string GetData(string value);


// TODO: Add your service operations here
}

[DataContract]
public class DomainData
{
    [DataMember]
    public int? KPIId
    {
        get;
        set ;
    }

[DataMember]
public int? ScorecardId
{
    get;
    set;
}

[DataMember]
public short? CumulativeMonth
{
    get;
    set;
}

[DataMember]
public int? EngineeringOrgId
{
    get;
    set;
}

[DataMember]
public int? BusinessOrgId
{
    get;
    set;
}
[DataMember]
public int? DataValuetypeId
{
    get;
    set;
}

}

当我使用 Restsharp 使用此服务时，如下所示

string URL = "http://<servername>:8085/WinPhoneService.svc";

            RestClient client = new RestClient(URL);

            RestRequest request = new RestRequest("getkpimeasuredata",Method.POST);
            DomainData data = new DomainData();
            data.KPIId = 1006;
            data.ScorecardId = 3;
            data.EngineeringOrgId = 11;
            data.DataValuetypeId = 1;
            data.CumulativeMonth = 463;
            data.BusinessOrgId = 1;

            string json = Newtonsoft.Json.JsonConvert.SerializeObject(data);

            json = "{\"data\" : " + json + "}";

            request.AddParameter("application/json; charset=utf-8", json, ParameterType.RequestBody);
            request.RequestFormat = DataFormat.Json;
 client.ExecuteAsync(request, response =>
            {
                if (response.StatusCode == HttpStatusCode.OK)
                {



                }
                else
                {
                    //NOK
                }
            });

甚至尝试了如下的webget方法..

 RestClient client1 = new RestClient(URL);
            RestRequest request1 = new RestRequest(string.Format("getdata/{0}", 1), Method.GET);
            request1.RequestFormat = DataFormat.Json;

            var x = client1.ExecuteAsync(request1, response =>
                {
                    if (response.StatusCode == HttpStatusCode.OK)
                    {

                    }
                });

我能够将 response.StatusCode 设置为 NotFound，即使我检查了提琴手 服务根本没有命中，并且当我验证了服务 URL 时 在作曲家我得到错误为 "HTTP/1.1 405 方法不允许"

甚至当我尝试使用如下 Webclient 时

string URL = "http://<servername>:8085/WinPhoneService.svc";
            WebClient wclient = new WebClient();
            wclient.UseDefaultCredentials = true;
            wclient.Headers["Content-Type"] = "application/json";


            DomainData kpidata = new DomainData();
            data.KPIId = 1006;
            data.ScorecardId = 3;
            data.EngineeringOrgId = 11;
            data.DataValuetypeId = 1;
            data.CumulativeMonth = 463;
            data.BusinessOrgId = 1;

            string json = SerializeJson(kpidata);
            String str = wclient.UploadString(new Uri(URL ),"getkpimeasuredata",json);

即使在这里我得到“HTTP/1.1 405 Method Not Allowed”，但至少在这种情况下它如fiddler所示命中服务

请帮助我解决同样的问题..

我在win8手机应用中使用的功能是

public async void  LoadKpiData()
        {
                       string URL = "http://rr1biscdevsql01:8085/WinPhoneService.svc/getkpimeasuredata;
            WebClient wclient = new WebClient();
            wclient.UseDefaultCredentials = true;
            wclient.Headers["Content-Type"] = "application/json";

            DomainData kpidata = new DomainData();
            kpidata.KPIId = 1006;
            kpidata.ScorecardId = 3;
            kpidata.EngineeringOrgId = 11;
            kpidata.DataValuetypeId = 1;
            kpidata.CumulativeMonth = 463;
            kpidata.BusinessOrgId = 1;

            string json = SerializeJson(kpidata);
            wclient.UploadStringAsync(new Uri(URL), json);

            wclient.UploadStringCompleted += (s, e) =>
                {

                };

        }

当我检查 Restclient 调用的响应时，出现如下错误

拉杰什 当我添加 [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)] 在服务中和

<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>

在 webconfig 中出现错误，因为服务无法激活，因为它不支持 ASP.NET 兼容性。为此应用程序启用了 ASP.NET 兼容性。在 web.config 中关闭 ASP.NET 兼容模式，或将 AspNetCompatibilityRequirements 属性添加到服务类型，并将 RequirementsMode 设置为“允许”或“必需”。

实际上，当我在 localhost 中运行服务时它工作正常，但是当我托管服务时它抛出错误..请帮助....

Answer 1

[WebInvoke(... , Method = "POST" ... )]List<MeasureData> GetKpiMeasureData(DomainData data);

上面的代码你使用了 POST 方法，但是你必须使用 GET 方法，因为 POST 方法只用于添加数据。

Http 动词是 POST 、 GET 、 Delete 和 PUT(Update) 。你必须先学习。

I used Get method and RestSharp.dll for my project 如果您想将我的项目用于 POST 方法，您可以使用以下代码

客户端

 var client1 = new RestClient("http://localhost:61111/Service1.svc");
            var request1 = new RestRequest("/AddPerson", Method.POST);
            Person person1 = new Person();
            person1.PersonID = 2;
            person1.Name = "Robert";
            person1.SurName = "Dan";
            JsonSerializer serial = new JsonSerializer();

            string temp = serial.Serialize(person1);
            Console.WriteLine(temp);
            Person tempPerson1 = new JavaScriptSerializer().Deserialize<Person>(temp);
            Console.WriteLine(tempPerson1.PersonID + " " + tempPerson1.Name + " " + tempPerson1.SurName);

服务器端

public class Service1 : IService1
{       
    private Person person = new Person() { PersonID = 1, Name = "John", SurName = "Albert" };
    public Person GetPerson()
    {
        return person;
    }
    public Person AddPerson(Person person)
    {
        return person;
    }
}


[ServiceContract]
public interface IService1
{

    [OperationContract]
    [WebInvoke(Method="GET", ResponseFormat = WebMessageFormat.Json, UriTemplate = "/GetPerson")]
    Person GetPerson();
    [OperationContract]
    [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, UriTemplate = "/AddPerson")]
    Person AddPerson(Person person);
}

Answer 2

看看这段代码

我的服务器代码如下

[ServiceContract]
    public interface IWinPhoneService
    {
        [OperationContract]
        [WebInvoke(RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "getkpimeasuredata")]
        List<String> GetKpiMeasureData(DomainData data);
    }

[DataContract]
    public class DomainData
{
    [DataMember]
    public int? KPIId { get; set; }

    [DataMember]
    public int? ScorecardId { get; set; }

    [DataMember]
    public short? CumulativeMonth { get; set; }

    [DataMember]
    public int? EngineeringOrgId { get; set; }

    [DataMember]
    public int? BusinessOrgId { get; set; }

    [DataMember]
    public int? DataValuetypeId { get; set; }
}

现在我的接口实现如下

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
    public class WinPhoneService : IWinPhoneService
    {
        public List<string> GetKpiMeasureData(DomainData data)
        {
            if (data != null)
            {
                return new List<string>()  {"Sample 1","Sample 2"};
            }
            return new List<string>() {"No data recieved"};
        }
    }

用于端点元素配置的服务器端 web.config

<system.serviceModel>
<services>
    <service name="WinPhoneService.WinPhoneService">
            <endpoint address="" binding="webHttpBinding" behaviorConfiguration="web" bindingConfiguration="defaultRestJsonp" contract="WinPhoneService.IWinPhoneService">
            </endpoint>
          </service>
    </services>
    <behaviors>
    <endpointBehaviors>
            <behavior name="web">
              <webHttp />
              <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
            </behavior>        
    </endpointBehaviors> 
    </behaviors>
    <bindings>   
    <webHttpBinding>
            <binding name="defaultRestJsonp" crossDomainScriptAccessEnabled="true">
              <readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxDepth="64" maxNameTableCharCount="2147483647" />
              <security mode="None" />
            </binding>
  </webHttpBinding>
  </bindings>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />     
 </system.serviceModel>  

现在有了以上所有设置，使用 RestSharpClient 在下面找到我的客户端代码：

private static string ToStringUsingDataContractJsonSer<T>(T requestBody)
        {
            var serializer = new DataContractJsonSerializer(typeof(T));
            var ms = new MemoryStream();
            serializer.WriteObject(ms, requestBody);
            ms.Position = 0;
            var reader = new StreamReader(ms);
            return reader.ReadToEnd();
        }

private string UseRestSharpApproach(string serviceBaseUrl, string resourceUrl, Method method, object requestBody)
        {
            var client = new RestClient();
            client.BaseUrl = serviceBaseUrl;
            var request = new RestRequest(method) { DateFormat = DataFormat.Xml.ToString(), Resource = resourceUrl };
            request.AddParameter("application/json", requestBody, ParameterType.RequestBody);            
            var response = client.Execute(request);

            string responseString;
            if (response.StatusCode == HttpStatusCode.OK)
            {
                responseString = HttpUtility.HtmlDecode(response.Content);
            }
            else
            {
                responseString = response.StatusDescription + " --------------------" + HttpUtility.HtmlDecode(response.Content);
            }
            return responseString;
        }

public void CallRESTService()
{
       UseRestSharpApproach(serviceBaseUrl, resourceUrl, Method.POST, ToStringUsingDataContractJsonSer<DomainData>(objDomainData));
}

确保在客户端使用时的 DomainData 对象与在服务器上使用的名称空间相同，以便序列化和反序列化顺利进行。

现在我来自 Fiddler 的原始请求如下所示：
