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);
        }
    }

我可以使用此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);
            }
        });

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

知道为什么吗?

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。你应该做的是这样的事情:

添加内容类型标头,其值为application/json

并为您的请求正文选择raw,然后添加您的JSON:

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" }
