jquery Ajax异步请求之session，jqueryajax
写了一个脚本,如下:

 

1 $(function () { 2 $("#btnVcode").click(function () { regMobile = /^1[3|4|5|7|8][0-9]\d{8}$/;(!regMobile.test(receiveMobile)) { 7 helper.dialogError('手机号格式不对'); 8 return; 9 } 10 $.post('/Register/SendSms', { Moblie: receiveMobile }, function (jsonObj) { }); 14 },'json'); 15 }); 16 });

 

手机号码验证通过后,会去后台调用发送短信接口,如果短信发送成功,会创建session ,而session的原理有一点是要在客户端浏览器创建cookie用来存ASP.NET_SessionId.

刚写完这段代码时担心Ajax异步请求不会创建本地cookie存sessionId.　　~.~

因为后台返回的是一个Json字符串: {"status":0,"msg":"短信已发送,请注意查收!"}

纠结了一会,想怎么解决.

 

试试再说,经测试,竟然创建cookie了.(后台没有操作cookie,返回的结果是字符串,也没有用jquery去操作去生成cookie,然而,然而,却有了...有了...)

{"status":0,"msg":"短信已发送,请注意查收!"}

 

真的有了.据分析,应该是 

　　Session[Keys.smsVcode] = vcode;//短信发送成功才创建session 

这行代码会 自动创建一个cookie并放入响应流(类似 Response.Cookies.Add(...) ),体现在报文的头部,浏览器收到报文,根据

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

创建了cookie.

 

分析完毕.
