Ajax 如何执行 Response.Redirect

Ajax 直接对服务端的Response.Redirect是不感冒的, 另觅途径, 具体可行办法如下:

Web Service 服务端:

public WXService()
    {
        if (!IsValidTicket)
        {
            string result = "{\"success\": true}";
            Context.Response.Clear();
            Context.Response.ContentType = "application/json; charset=UTF-8";
            Context.Response.Headers.Add("Redirect", "true");
            Context.Response.Headers.Add("RedirectUrl", "Errors.aspx?code=401");
            Context.Response.Flush();
            Context.Response.Write(result);
            throw new Exception("Ticket is logout.");
        }
    }

ajax 客户端:

全局定义:
$.ajaxSetup({
    complete: function (XMLHttpRequest, textStatus) {
        var redirect = XMLHttpRequest.getResponseHeader("Redirect");
        if (redirect == "true") {
            window.location.href = XMLHttpRequest.getResponseHeader("RedirectUrl");
        }
    }
});

响应结果如下:
