我正在开发 wcf 服务。我在我的 windows 手机应用程序中得到了很好的响应。但是 android 人得到了错误。他们得到了 html 响应。即，（我的 wcf 调试浏览器页面）。下面是我的代码：
namespace SampleWcfproject
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "ISampleService1" in both code and config file together.
[ServiceContract]
public interface ISampleService1
{
[OperationContract]
[WebInvoke(UriTemplate = "/getdata/{uuid}", Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
string getdata(string uuid);
[OperationContract]
string getcities();
}}
我的 svc.cs 页面：
namespace SampleWcfproject
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "SampleService1" in code, svc and config file together.
// NOTE: In order to launch WCF Test Client for testing this service, please select SampleService1.svc or SampleService1.svc.cs at the Solution Explorer and start debugging.
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
[AspNetCompatibilityRequirements(
RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
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();
var rowString = JSSerializer.Serialize(DtRows);
//rowString = rowString.Trim('"');
rowString = rowString.Substring(1, rowString.Length - 2);
return rowString;
}
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";
