c# - 远程服务器返回错误：(415) Unsupported Media Type using API in asp.net

问题描述

我想API在我的应用程序中使用。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。

当我调试这行代码时产生上述错误，

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"}]}

我不明白错误的根本原因是什么。请帮忙

解决方案

经过我从客户端获得的大量调试和响应数据。

试一试。我所做的是

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

例如：- 之前的响应类名称是IEIncrementalData我发送的。但 API 响应是SiteData，它有 11 个参数。所以我创建了具有相同名称和相同参数的类。

这样做之后它对我有用。！
