发布请求未收到任何数据

Question

I am trying to make a PostRequest from Unity that creates a new account in a database. When I run the Post Request function(click the submit button), a new Account is created in the database but all of the values are null. I am unable to get any of the data at the controller. I am sending the data as a string in Json format. Any help is appreciated.

Controller:

    [HttpPost]
    public string Post([FromForm] Account data )
    {
        Console.WriteLine("Data user name: " +data.userName);
        db.Accounts.Add(data);
        db.SaveChanges();
        Console.WriteLine(data);
        return "success";
    }

PostRequest from Unity

    public void AddAccount()
    {

    WebRequest request = (HttpWebRequest)WebRequest.Create("https://localhost:44301/accounts" );
    request.Method = "POST";

    string json = " { \"highScores\":[],\"lazyLoader\":{},\"userName\":user\",\"password\":testpassword",\"displayName\":name"} ";
    byte[] byteArray = Encoding.UTF8.GetBytes(json);

    request.ContentType = "application/json; charset=UTF-8";

    request.ContentLength = byteArray.Length;

    Stream dataStream = request.GetRequestStream();

    dataStream.Write(byteArray, 0, byteArray.Length);

    dataStream.Close();

    WebResponse response = request.GetResponse();

    Debug.Log(((HttpWebResponse)response).StatusDescription);

    using (dataStream = response.GetResponseStream())
    {
        StreamReader reader = new StreamReader(dataStream);

        string responseFromServer = reader.ReadToEnd();

        Debug.Log(responseFromServer);
    }

}

You're sending content body with type application/json . Form datas are sent via x-www-form-urlencoded . You need to change parameter binder [FromForm] to [FromBody] on your controller action.

Secondly, " { \\"highScores\\":[],\\"lazyLoader\\":{},\\"userName\\":user\\",\\"password\\":null,\\"displayName\\":null} " is not a valid Json. When you change to FromBody binder, the deserializer will throw serialization exception. You need to fix the json data, also.
