 IEnumerable<ReportObject> IHttpReceiveReport.OnPost(System.Web.HttpContextBase context)
        {
            //[{"time":"20161012150400","taskid":"30cf60a756d444b986b9e3909e3b107a","code":"DELIVRD","msg":"提交成功","mobile":""}]
            var request = context.Request;
            request.InputStream.Position = 0;
            StreamReader reader = new StreamReader(request.InputStream);
            string result = reader.ReadToEnd();
}
