远程服务器返回错误:(415) 在 asp.net 中使用 API 不支持的媒体类型

Question

我想在我的应用程序中使用API。所以我像下面这样使用它

IEIncrementalData objIncrement = new IEIncrementalData();
IEIncrementalData[] arrIncrementData = new IEIncrementalData[1];
objIncrement.SAPID = Convert.ToString(grdDisplayFCAData.Rows[gvrow.RowIndex].Cells[0].Text).Replace(" ","");
objIncrement.SiteRFEIDate = Convert.ToString(grdDisplayFCAData.Rows[gvrow.RowIndex].Cells[8].Text).Replace(" ", "");
objIncrement.SiteRFSDate = Convert.ToString(grdDisplayFCAData.Rows[gvrow.RowIndex].Cells[9].Text).Replace(" ", "");
objIncrement.ID_OD = Convert.ToString(grdDisplayFCAData.Rows[gvrow.RowIndex].Cells[1].Text).Replace(" ", "");
objIncrement.ID_OD_CHANGEDATE = Convert.ToString(grdDisplayFCAData.Rows[gvrow.RowIndex].Cells[2].Text).Replace(" ", "");
if (string.IsNullOrEmpty(Convert.ToString(grdDisplayFCAData.Rows[gvrow.RowIndex].Cells[4].Text).Replace(" ", "")))
{
objIncrement.NoofRRHBase = "0";
}
else 
{
objIncrement.NoofRRHBase = Convert.ToString(grdDisplayFCAData.Rows[gvrow.RowIndex].Cells[4].Text).Replace(" ", "");
}

objIncrement.SiteStatus = "".Replace(" ", "");
objIncrement.SiteDropDate = "".Replace(" ", "");
objIncrement.RRH_CHAGEDDATE = Convert.ToString(grdDisplayFCAData.Rows[gvrow.RowIndex].Cells[5].Text).Replace(" ", "");
objIncrement.TENANCY_COUNT = Convert.ToString(grdDisplayFCAData.Rows[gvrow.RowIndex].Cells[6].Text).Replace(" ", "");
objIncrement.TENANCY_CHANGEDDATE = Convert.ToString(grdDisplayFCAData.Rows[gvrow.RowIndex].Cells[7].Text).Replace(" ", "");
arrIncrementData[0] = objIncrement;
string apiUrl = ConfigurationManager.AppSettings["WebApiUrl"].ToString();
var inputIPColoMaster = new
{
IEIncrementalData = arrIncrementData,
};
string inputJsonIPColoMaster = (new JavaScriptSerializer()).Serialize(inputIPColoMaster);
WebClient client = new WebClient();
client.Headers["Content-type"] = "application/json";
client.Encoding = Encoding.UTF8;
string json = client.UploadString(apiUrl, inputJsonIPColoMaster);
DataTable dtRes = new DataTable();
string GISSendDate = System.DateTime.Now.Date.ToString("dd-MM-yyyy", new System.Globalization.CultureInfo("en-US"));
StringReader sr = new StringReader(json);
dtRes = JsonConvert.DeserializeObject<DataTable>(json);

但是在使用提到的 api 时，我收到错误

远程服务器返回错误：(415( 不支持的媒体类型。

调试这行代码时产生的上述错误，

string json = client.UploadString(apiUrl, inputJsonIPColoMaster);

生成的 json 如下：-

{"IEIncrementalData":[{"SAPID":"I-PB-AMRR-ENB-I042","SiteRFEIDate":"23/10/2018","SiteRFSDate":"Approved","ID_OD":"","ID_OD_CHANGEDATE":"","NoofRRHBase":"24/10/2018","SiteStatus":"","SiteDropDate":"","RRH_COUNT":null,"RRH_CHAGEDDATE":"","TENANCY_COUNT":"","TENANCY_CHANGEDDATE":"23/10/2018"}]}

错误的根本原因究竟是什么？

Answer 1

经过我从客户端获得的大量调试和响应数据。

试了一下。我所做的是

I created the Parameters with same name as the response was generating from the API

例如：- 早些时候，响应类名是我发送的IEIncrementalData。但是 API 响应是SiteData的，它有 11 个参数。所以我创建了具有相同名称和相同参数编号的类。

这样做之后它对我有用。！！
