jquery Ajax異步請求之session

寫了一個腳本,如下:

 

$(function () {
            $("#btnVcode").click(function () {
                var receiveMobile = $("#Moblie").val();//手機號
                var regMobile = /^1[3|4|5|7|8][0-9]\d{8}$/;//驗證手機

                if (!regMobile.test(receiveMobile)) {
                    helper.dialogError('手機號格式不對');
                    return;
                }
                $.post('/Register/SendSms', { Moblie: receiveMobile }, function (jsonObj) {
                    helper.checkAjaxStatus(jsonObj, function() {                   13                     });
                },'json');
            });
        });

 

手機號碼驗證通過后,會去后台調用發送短信接口,如果短信發送成功,會創建session ,而session的原理有一點是要在客戶端瀏覽器創建cookie用來存ASP.NET_SessionId.

剛寫完這段代碼時擔心Ajax異步請求不會創建本地cookie存sessionId.　　~.~

因為后台返回的是一個Json字符串: {"status":0,"msg":"短信已發送,請注意查收!"}

糾結了一會,想怎么解決.

 

試試再說,經測試,竟然創建cookie了.(后台沒有操作cookie,返回的結果是字符串,也沒有用jquery去操作去生成cookie,然而,然而,卻有了...有了...)

{"status":0,"msg":"短信已發送,請注意查收!"}

 

真的有了.據分析,應該是 

　　Session[Keys.smsVcode] = vcode;//短信發送成功才創建session 

這行代碼會 自動創建一個cookie並放入響應流(類似 Response.Cookies.Add(...) ),體現在報文的頭部,瀏覽器收到報文,根據

　　 Set-Cookie: ASP.NET_SessionId=zbdy1ndgta2g02lysrfv1rhj; path=/; HttpOnly

創建了cookie.

 

分析完畢.
