mvc后台post发送json数据

代码比较简单，不废话，直接上代码：

/// <summary>/// 提交json数据，并接收/// </summary>/// <param name="apipath">要请求的服务器地址</param>/// <param name="jsonStr">要提交的json数据</param>/// <returns></returns>public static string PostDataWithJson(string apipath,string jsonStr){HttpContent content = new StringContent(jsonStr);content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/json");var httpClient = new HttpClient();var responseJson = httpClient.PostAsync(apipath, content).Result.Content.ReadAsStringAsync().Result;return responseJson;}

要引入命名空间：using System.Net.Http;
