400 badrequest при потреблении wcf-сервиса?

Question

Я разработал один wcf service.it работает нормально в моем локальном при потреблении service.but, что случилось, этот сервис опубликован на сервере. Затем всякий раз, когда потребляемая эта услуга получает 400 bad request.please, помогите мне.

ниже мой код:

namespace SampleWcfproject 
{ 
    [ServiceContract] 
    public interface ISampleService1 
    { 
     [OperationContract] 
     //[WebInvoke(Method="GET",ResponseFormat=WebMessageFormat.Json,BodyStyle=WebMessageBodyStyle.Wrapped,UriTemplate="getdata")] 
     [WebInvoke(UriTemplate = "/getdata/{uuid}", Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] 
     string getdata(string uuid); 

     [OperationContract] 
     string getcities(); 
    } 
} 

sampleservice.svc.cs:

[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)] 
public class SampleService1 : ISampleService1 
{ 
     public string getdata(string uuid) 
     { 
      try 
      { 


       SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["con2"].ConnectionString); 
       SqlCommand comm = new SqlCommand("select CircleID, CircleName from Circle", con); 
       con.Open(); 
       comm.ExecuteNonQuery(); 

       SqlDataAdapter da = new SqlDataAdapter(comm); 
       // DataSet ds = new DataSet(); 
       DataTable dt = new DataTable(); 
       da.Fill(dt); 

       JavaScriptSerializer JSSerializer = new System.Web.Script.Serialization.JavaScriptSerializer(); 
       List<Dictionary<string, object>> DtRows = new List<Dictionary<string, object>>(); 
       Dictionary<string, object> newrow = null; 

       //Code to loop each row in the datatable and add it to the dictionary object 
       foreach (DataRow drow in dt.Rows) 
       { 
        newrow = new Dictionary<string, object>(); 
        foreach (DataColumn col in dt.Columns) 
        { 
         newrow.Add(col.ColumnName.Trim(), drow[col]); 
        } 
        DtRows.Add(newrow); 
       } 
       con.Close(); 


       return JSSerializer.Serialize(DtRows); 
      } 
      catch (Exception ex) 
      { 

       List<String> Parameters = new List<String>(); 
       Parameters.Add("getRechargeCircleList"); 

      // SendErrorMail(ex.ToString(), "getRechargeCircleList", Parameters); 
       // Context.Response.ContentType = "application/json; charset=utf-8"; 
       // Context.Response.Write(@" {""Status"":""false"",""Message"" : ""Oops! Something went Wrong""}"); 
       // return; 
      } 
      return "false"; 
     } 
    } 
}

На самом деле, что случилось эта услуга работает нормально в my .net project. Я добавляю эту службу, используя ссылку на сервисную службу и получая данные нормально. Но всякий раз, когда я нахожусь httpWebRequest, тогда пришло 400 badrequest. Что я должен делать. Я не знаю, что произошло.

Обновлено:

Я получаю ответ в моем Windows Phone приложение. но люди андроидов получают ошибку. Они получают html response.i.e., мою страницу отладки wcf отладки.

Answer 1

Пожалуйста, измените Service Model Configuration как этот

Удалить <endpoint address="" binding="netTcpBinding" contract="SampleWcfproject.IService1"/>

<service behaviorConfiguration="SampleWcfproject.Service1Behavior" name="SampleWcfproject.Service1"> 

    <endpoint address="" binding="basicHttpBinding" contract="SampleWcfproject.IService1"> 

    <identity> 
<dns value="localhost"/> 
    </identity> 
    </endpoint> 

    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> 
    </service>
