Web Controller:

public void SignIn(UserInfo user, IList<string> roleList, bool rememberMe = false)
{
    Audit audit = new Audit()
        {                
            UserName = user.UserName,
            Role = roleList[0].ToString(),
            ControllerAccessed = "Login",
            MethodAccessed = "Login",
            TimeAccessed = DateTime.UtcNow,
            IsLogin = true,               
            Is_Report = false,
            Report_Type = null,
            Report_Name = null
        };
     PostAPIData<int>(apiBaseUrl   "api/AuditAPI/LogUIAudit", audit);
}

public class Audit
{        
    public string UserName { get; set; }
    public string Role { get; set; }        
    public string ControllerAccessed { get; set; }
    public string MethodAccessed { get; set; }
    public DateTime TimeAccessed { get; set; }
    public bool IsLogin { get; set; }
    public bool Is_Report { get; set; }
    public string Report_Type { get; set; }
    public string Report_Name { get; set; }
    
}

public T PostAPIData<T>(string url, object obj)
{
    using (HttpClient client = new HttpClient())
    {
        var responseTask = client.PostAsJsonAsync(url, obj);
        responseTask.Wait();
        var result = responseTask.Result;
    }
}

In above SignIn method, I'm passing 2 different api calls with respective model classes. So I defined it as obj in the PostAPIData method. and one of the url is https://localhost:44306/api/AuditAPI/LogUIAudit. When this code hits the below API Controller, parameters turns empty:

API Controller:

[Route("api/AuditAPI/LogUIAudit")]
[HttpPost]
public int LogUIAudit(Audit AuditEntry)
{
} 

I tried below conversions. But none of them works.

1:

StringContent content = new StringContent(JsonConvert.SerializeObject(obj), Encoding.UTF8, "application/json");
var responseTask = client.PostAsJsonAsync(url, content);    

2:

StringContent content = new StringContent(JsonConvert.SerializeObject(AuditEntry), Encoding.UTF8, "application/json");
var responseTask = client.PostAsync(url, content); 

3:

Audit AuditEntry = (Audit)obj;
StringContent content = new StringContent(JsonConvert.SerializeObject(AuditEntry), Encoding.UTF8, "application/json");
var responseTask = client.PostAsync(url, content);

Both client and server is running. But when I debug the code, all the properties of that model class are shown as null.

CodePudding user response：

In order to get your data in your API Controller, you should use the FromBody attribute to bind your model correctly:

[Route("api/AuditAPI/LogUIAudit")]
[HttpPost]
public int LogUIAudit([FromBody]Audit AuditEntry)
{

}
