我如何将json对象传递给webapi控制器(POST)并且没有将其映射到的类,而是将其作为任意内容处理？

所以如果我这样从我的客户端传入:

        createRecord: function (model, data, callback, callbackParams) {
        var request = jQuery.ajax({
            type: "POST", // default = GET,
            url: '/api/' + model + '/',
            data: data,
            contentType: 'application/json',
            success: function (msg) {
                $('#results').text(msg);
                if (callback) // only fire a callback if it has been specified
                    callback(msg, callbackParams);
            },
            error: function (jqXHR, textStatus) {
                alert('Request failed: ' + textStatus);
            }
        });
    }

和数据是这样的:

{ "_id" : ObjectId("5069f825cd4c1d590cddf206"), "firstName" : "John", "lastName" : "Smith", "city" : "Vancouver", "country" : …

传递参数时出错,

"无法绑定多个参数"

这是我的代码

[HttpPost]
public IHttpActionResult GenerateToken([FromBody]string userName, [FromBody]string password)
{
    //...
}

阿贾克斯:

$.ajax({
    cache: false,
    url: 'http://localhost:14980/api/token/GenerateToken',
    type: 'POST',
    contentType: "application/json; charset=utf-8",
    data: { userName: "userName",password:"password" },

    success: function (response) {
    },

    error: function (jqXhr, textStatus, errorThrown) {

        console.log(jqXhr.responseText);
        alert(textStatus + ": " + errorThrown + ": " + jqXhr.responseText + "  " + jqXhr.status);
    },
    complete: function (jqXhr) {

    },
})

如何使用Angular2正确创建复杂对象或多个参数的Web API POST？

我在Angular2中有一个服务组件,如下所示:

public signin(inputEmail: string, inputPassword: string): Observable<Response> {
    return this.http.post('/api/account/signin', JSON.stringify({ Email: inputEmail, Password: inputPassword}), this.options);
}

目标web api如下所示:

[HttpPost]
[Route("signin")]
public async Task<IActionResult> Signin(string email, string password)
{
       ....
}

这不起作用,因为我需要将web api的参数转换为具有Email和Password属性的单个POCO类实体,并放置[FromBody]属性: Signin([FromBody] Credential credential)

如果不使用[FromURI](带有查询字符串的POST请求？),如何在不将这些参数转换为单个POCO类的情况下对多个参数或复杂对象进行POST？

因为如果我有许多带有参数的Web API POST操作,(string sensitiveInfo1, string name, int sensitiveInfo2)或者(ClassifiedInfo info, string sensitiveInfo1, string sensitiveInfo2),我是否需要将它们全部转换为POCO类并始终使用[FromBody]？

PS.我以前使用RestangularJS它,它可以发布任何东西(多个原始对象和复杂对象),而我的Web API操作没有[FromBody]属性.将研究RestangularJS如何做到这一点.

我使用的是asp.net 4.5和最新的MVC版本.在html页面中发布表单时deviceId,我需要retrive 和bodyheader.在行public void Post([FromBody]string value)值处,它始终为null.

我在这做错了吗？

  namespace WebApi.Controllers
    {
        public class NotificationController : ApiController
        {
            // GET api/notification
            public IEnumerable<string> Get()
            {
                return new string[] { "value1", "value2" };
            }

            // GET api/notification/5
            public string Get(int id)
            {
                return "value";
            }

            // POST api/notification
            public void Post([FromBody]string value)
            {
// value it is always null
            }

            // PUT api/notification/5
            public void Put(int id, [FromBody]string value)
            {
            }

            // DELETE api/notification/5
            public void Delete(int …

我有一个带有更新操作的 ASP.Net Core WebApi，如下所示：

   [HttpPut("{id}")]
    public async Task<IActionResult> Campaigns(long id, JObject jobject)
    {

    }
