使用HttpClient发送数据 到WebApi

发送和JSON数据

/=============================webAPI接受POST的JOSN数据=============================/
 POST api/<controller>
[HttpPost]
public string Post([FromBody]string value)
{
    var requestContent = value;
    var result = "[{"name":"12"}]";
    return result;
}


// 发送方法
public void SendStringToWebApi()
{
	
	#region 调用API发送字典数据

            // (orders+vehicles+appkey+timestamp+version+appsecret)
            var timestamp = DateTime.Now.ToString("yyyyMMddHHmmssSSS");
            var sign = DigitalSignature.MD5(JsonConvert.SerializeObject(listOrder) + appkey + timestamp + "1" + appsecret);
            var qid = timestamp + sign;

            var url = "http://www.routeapi.com/api/Order";
            var handler = new HttpClientHandler() { AutomaticDecompression = DecompressionMethods.GZip };

            using (var http = new HttpClient(handler))
            {
                // 发送的JSON数据
                var _TrasnTask = new TrasnTask()
