在MVC 5中,我重写HandleUnauthorizedRequest()
并检查请求是否来自AJAX。
我还注册了一个全局ajaxComplete
,用于处理401 AJAX请求,但在HandleUnauthorizedRequest()
之后状态代码仍为200。
问题:我是否必须手动更改filterContext
功能中HandleUnauthorizedRequest()
的状态代码?
检测到未经授权的AJAX请求
protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
{
if (filterContext.HttpContext.Request.IsAjaxRequest())
{
// <-- in here
filterContext.Result = new JsonResult
{
Data = new
{
returnUrl = "foo"
},
JsonRequestBehavior = JsonRequestBehavior.AllowGet
};
}
else
{
base.HandleUnauthorizedRequest(filterContext);
}
}
全球ajax完成注册
$(document).ajaxComplete(function (e, xhr, settings) {
console.log('xhr.status: "' + xhr.status +'"'); // 200 - i want 401
if(xhr.status === 401) {
window.location.replace(urlHelper.getUrlNotAuthorized());
}
});
&#34;工作但遭到黑客攻击的解决方案,直到找到ajaxComplete的解决方案。
检查用户请求是否已获得授权。缺点是,我必须检查isAuthorized()
我提出请求。这就是我想使用全局ajaxComplete的原因,所以我绝不会错过任何一个。&#34;:
检查用户AJAX请求是否已获得授权
isAuthorized = function (result) {
try {
var obj = JSON && JSON.parse(result) || $.parseJSON(result);
// Here, obj can still be a parsed JsonResult, from when getting GetDatatableRows(), so we also need to check on returnUrl which is distinct
// obj will only contain returnUrl if the JSON was returned from Shield validation
if (obj && obj.returnUrl) {
window.location.replace(urlHelper.getUrlNotAuthorized() + '?returnUrl=' + encodeURIComponent(obj.returnUrl));
return false;
}
} catch (e) {
}
return true;
};
AJAX请求,其中结果是部分视图或JSON
partialViewService.changePartialViewService(url, data)
.done(function (result) {
if (isAuthorized(result)) {
// use result
}
});
答案 0 :(得分:4)
是 - 我没有检查过这个,但尝试添加指示的行。指定代码401不会过滤到您想要的结果。 (我怀疑这是由于身份截取代码401具体而言):
protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
{
if (filterContext.HttpContext.Request.IsAjaxRequest())
{
// Add this (code 401 does not work)
filterContext.HttpContext.Response.StatusCode = 412;
// <-- in here
filterContext.Result = new JsonResult
{
Data = new
{
returnUrl = "foo"
},
JsonRequestBehavior = JsonRequestBehavior.AllowGet
};
}
else
{
base.HandleUnauthorizedRequest(filterContext);
}
}
