asp.net json参数请求接口方法

废话不多说，直接上源码

 

调用代码：

 

//请求实体
var model = new Personnel()
{
Name = "赵思文",
Sex = "男"
};

//请求接口
var html = PostHtmlByJson("http://www.test.api.com", JsonConvert.SerializeObject(model));

 

 

请求方法

 /// 

        /// post请求方法
        /// 
        /// 请求地址
        /// json参数
        /// 
        public static string PostHtmlByJson(string url, string json)
        {
            var result = string.Empty;
            object obj;
            try
            {
                var request = WebRequest.Create(url) as HttpWebRequest;
                if (request != null)
                {
                    request.ContentType = "application/json";
                    request.Method = "post";

                    //request.CookieContainer = _cookie;
                    using (var streamWriter = new StreamWriter(request.GetRequestStream()))
                    {
                        streamWriter.Write(json);
                        streamWriter.Flush();
                        streamWriter.Close();
                    }
