我开发了一个wcf service.it在使用服务时在我的本地工作正常。但是在服务器上发布的这个服务发生了什么。然后每当使用此服务获得400个错误请求时请帮助我。

下面是我的代码:

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";
       }
     }
}

实际上这个服务在我的.net项目中正常运行。我通过使用添加服务引用并正常获取数据来添加此服务。但每当我使用HttpWebRequest时,就会发出400 badrequest。我该怎么办。我不知道#39;不知道发生了什么。

已更新:

我的Windows手机应用程序收到回复。但安卓人员得到错误。他们正在获取html response.i.e。,我的wcf调试浏览器页面。

答案 0 :(得分:1)

请修改Service Model Configuration这样的

删除<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>
