Question

我正在使用Visual Studio 2013 ASP.NET身份模板。用户成功登录后，用户将转到带有表的页面。页面有搜索选项，搜索功能是javascript驱动的 javascript以ajax请求的形式发送用户选择的参数我遇到了问题，因为AJAX请求从客户端构造良好并发送到正确的URL但它立即被重定向并且参数丢失。我不确定是否会发生这种情况，因为请求应该经过身份验证/授权。我尝试了以下

            $.ajax({
                type: 'POST',
                url: '<%=Config.VirtualDir %>listings.aspx' + '?filterattribute=y&call=ajax',
                data: { 'zipcode': ZipCode, 'bedrooms': BedRooms, 'bathrooms': Bathroom, 'SquareFeetMin': SquareFeetMin, 'SquareFeetMax': SquareFeetMax, 'PriceMin': MinPrice, 'PriceMax': MaxPrice, 'Radius': Radius, 'Years': Years, 'IntRate': IntRate, 'DownPayment': DownPayment, 'sort': ddlsort, 'crfrom': capfrom, 'crto': capto, 'cffrom': cflowfrom, 'cfto': cflowto, 'roifrom': roifrom, 'roito': roito, 'vefrom': vefrom, 'veto': veto, 'chksupp': supp, 'undadd': undadd },
                beforeSend: function(xhr){
                    xhr.withCredentials = true;
                },
                success: function (response) {
                    $('#DivRender').html(response);
                    DisplayPaging();
                    UpdateDropDowns();
                    $.hideprogress();
                }
            });

我检查了如何在Fiddler中处理请求，这是发生了什么

如何确保ajax post请求与请求一起发送会话cookie，以便重定向不会发生。

Answer 1

如果您想确保不受身份验证重定向的影响：

查看你的OWIN Startup类，你应该有这样的一行（取自默认的MVC，对于Web API来说类似）：

app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
            LoginPath = new PathString("/Account/Login"),

        });

此处的LoginPath属性会将所有未经身份验证的请求（如果请求需要授权）重定向到指定的路径。

在没有LoginPath的情况下再次尝试您的AJAX请求，您可能会获得401 Unauthorized。

如果您想保留LoginPath重定向但不希望它影响您的AJAX调用，请查看this post from Brock Allen，以便根据请求的应用程序以不同方式处理401.

Answer 2

在您的情况下，最好使用[WebMethod]而不是向页面发送请求。在WebMethod中，您也可以访问Session。

ASP.NET ajax发布请求被重定向
