如何使用WebRequest(无模型)将对象传递到外部Web Api ASP.NET MVC

Question

我有一个asp.net MVC和外部WEBAPI。我想按以下顺序传递数据：

1. 从Ajax到MVC控制器
2. 从MVC控制器到外部WEBAPI
3. 外部WEBAPI发送响应
4. MVC控制器收到响应
5. MVC控制器返回对AJAX的响应

问题：它可以保存到数据库，但所有值都为0。我路过的东西好像不见了，但我不知道在哪里。

在这方面真的需要帮助。感谢

下面是我调用MVC控制器的Ajax代码：

function savePostApplication(theData) {
var insert = {};
insert.JobTitleId = JobTitleId;
insert.Division = Division;
insert.SalaryScaleId = SalaryScaleId;
insert.DepartmentId = DepartmentId;
insert.MinistryId = MinistryId;
$.post("/Advert/AddAdvertApplication", theData,
function (response) {
alert(response);
});
}

这是我的MVC控制器代码：

public String AddAdvertApplication(JSON data)
{
var url = "https://localhost:44331/api/jobadvertisementdetails";
var wr = WebRequest.Create(url);
wr.Method = "POST";
string json = JsonConvert.SerializeObject(data);
byte[] byteArray = Encoding.UTF8.GetBytes(json);
wr.ContentType = "application/x-www-form-urlencoded";
wr.ContentLength = byteArray.Length;
var dataStream = wr.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
WebResponse response = wr.GetResponse();
var Status = ((HttpWebResponse)response).StatusDescription;
dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();
reader.Close();
dataStream.Close();
response.Close();
return responseFromServer;
}

这是我的WEBAPI代码：

public String PostJobAdvertisementDetail(JobAdvertisementDetail jobAdvertisementDetail)
{
try
{
DataTable table = new DataTable();
String query = @"insert into dbo.JobAdvertisementDetails (JobTitleId, Division, SalaryScaleId, DepartmentId, MinistryId) values (" + jobAdvertisementDetail.JobTitleId +
@"," + jobAdvertisementDetail.Division + "," + jobAdvertisementDetail.SalaryScaleId +
@","+jobAdvertisementDetail.DepartmentId+","+jobAdvertisementDetail.MinistryId+")";
using(var con = new SqlConnection(ConfigurationManager.ConnectionStrings["CONN"].ConnectionString))
using(var cmd = new SqlCommand(query, con))
using(var da = new SqlDataAdapter(cmd))
{
cmd.CommandType = CommandType.Text;
da.Fill(table);
}
return "Data Saved";
}
catch (Exception ex)
{
return "Error";
}
}

更新：它现在起作用了。我只是将内容类型从"；application/x-www-form-urlencoded"；至"；application/json"；
