【问题描述】：
我在 wcf 上工作了 7 天。我创建了一个 Wcf 服务。 但是工作正常并通过添加服务参考在 Visual Studio 中得到响应。但我的问题是，每当它集成到 android/windows 中时，那些人都没有得到响应。他们得到 400（错误请求）。请任何人帮助我如何得到正确的回应。 （我想要响应为 json）这是我下面的代码。 提前谢谢你。
在界面中
public interface ISampleService1
{
[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json, UriTemplate = "getdata",BodyStyle = WebMessageBodyStyle.Bare)]
string getdata();
}
在课堂上
public string getdata()
{
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";
}

我通过使用 Web 参考项目在 Visual Studio 中得到以下响应。但在 android 中出现类似 400 的错误。
[{""CircleID"":1,""CircleName"":""安得拉邦""},{""CircleID"":4,""CircleName"":""阿萨姆邦""},{ ""CircleID"":5,""CircleName"":""Bihar""},{""CircleID"":6,""CircleName"":""Chennai""},{""CircleID"": 7,""CircleName"":""Delhi""},{""CircleID"":8,""CircleName"":""Gujarat""},{""CircleID"":9,""CircleName" ":""喜马偕尔邦""},{""CircleID"":10,""CircleName"":""哈里亚纳邦""},{""CircleID"":11,""CircleName"":""查谟\u0026 克什米尔""},{""CircleID"":12,""CircleName"":""Kerala""},{""CircleID"":13,""CircleName"":""Karnataka""} ,{""CircleID"":14,""CircleName"":""加尔各答""},{""CircleID"":15,""CircleName"":""马哈拉施特拉邦""},{""CircleID" ":16,""CircleName"":""Madhya Pradesh""},{""CircleID"":17,""CircleName"":""Mumbai""},{""CircleID"":18," "CircleName"":""North East""},{""CircleID"":19,""CircleName"":""Orissa""},{""CircleID"":20,""CircleName"": ""Punjab""},{""CircleID"":21,""CircleName"":""Rajasthan""},{""CircleID"":22,""CircleName"}]");
这是我的网址 http://xyzmnmkljj.in/SampleService1.svc/getdata
但它给出了 400 个错误请求。
对 web.comfig 文件的任何修改请帮助我
