我正在关注Steven Sanderson的" Pro …

我有一个淘汰模型,正在提供我的页面和保存下面的代码是客户端执行.

self.save = function() {
    var tirerun = ko.mapping.toJSON(self.data());
    $.ajax({
        type: 'post',
        url: "@Url.Action("SaveTireRunModel", "Events")",
        data: tirerun,
        success: function(result) {
            if (!result.success) {
                alert(result.error);
            } else {}
        }
    });
};

然后它将以下JSON发布到我的服务器(来自fiddler并为简洁而裁剪)

使用以下http请求标头
