postman params没有发送到web api控制器

I have this web api controller:

我有这个web api控制器：

public class LoginController : ApiController
    {
        private mw2devnew15Entities db = new mw2devnew15Entities();

        [System.Web.Http.HttpGet]
        public string Post()
        {
            string authenticationToken = "";
            return authenticationToken;
        }


        [System.Web.Http.AcceptVerbs("GET", "POST")]
        public HttpResponseMessage Post(JObject data)
        {
            dynamic json = data;

            LoginForm loginF = new LoginForm();
            loginF.username = json.username;
            loginF.password = json.password;

            return Request.CreateResponse(HttpStatusCode.OK);
        }
    }

I'm able to post correctly with this ajax call:

我能用这个ajax调用正确发布：

jQuery.ajax({
            type: "POST",
            url: "http://localhost:5832/api/Login",
            data: JSON.stringify({ username: 'joep11aul1234', password: '1212213' }),
            contentType: "application/json; charset=utf-8",
            dataType: "json", 
            success: function (data) {
                alert(data);
            }
        });

But when I'm trying to use Postman to place POST call, the JObject is null.

但是当我尝试使用Postman进行POST调用时，JObject为null。

Any idea why?

知道为什么吗？

Using Postman you're not reproducing the same request as your JavaScript code since you posting the parameters in the query string. What you shoud do instead is something like this:

使用Postman，您不会再生成与JavaScript代码相同的请求，因为您在查询字符串中发布了参数。你要做的事情是这样的：

Add a content type header with the value of application/json:

使用application / json的值添加内容类型标头：

and for your request body select raw and then add your JSON:

并为您的请求正文选择raw然后添加您的JSON：

this will send the following request same as your JavaScript code:

这将发送与JavaScript代码相同的以下请求：

POST /api/Login HTTP/1.1
Host: localhost:5832
Content-Type: application/json
Cache-Control: no-cache
Postman-Token: 4bf25ded-7548-77f9-3389-fa16a5d50087

{ "username": "joep11aul1234", "password": "1212213" }
