Accept = "Application/json";            Req. ContentType = "Application/json; Charset=utf-8 ";            Req. Headers.set ("Odata-maxversion", "4.0");            Req. Headers.set ("Odata-version", "4.0");            Req. Headers.set ("Prefer", "Odata.include-annotations=odata.community.display.v1.formattedvalue");            using (HttpWebResponse res = (HttpWebResponse) req. GetResponse ())            {                StreamReader read = new StreamReader (res. GetResponseStream ());                result = read. ReadToEnd ();            }

var req = new XMLHttpRequest ()    req.open ("get", url);    Req.setrequestheader ("Accept", "Application/json");    Req.setrequestheader ("Content-type", "Application/json; Charset=utf-8 ");    Req.setrequestheader ("Odata-maxversion", "4.0");    Req.setrequestheader ("Odata-version", "4.0");    Req.setrequestheader ("Prefer", "Odata.include-annotations=odata.community.display.v1.formattedvalue");    Req.onreadystatechange = function () {        if (this.readystate = = 4) {            if (this.status = =) {                Successcallback (J Son.parse (This.responsetext));            }            else {                errorcallback (Json.parse (this.responsetext). error.message);}}}    ;    Req.send ();
