所以这里是:
我有一个 html 助手,它ActionLink
使用当前 url 的可选参数呈现 s 。这个 html 帮助器还允许您根据需要添加更多可选参数并将它们合并到 1 中RouteValueDictionary
。
public static string ActionLinkwParams(this HtmlHelper helper, string linktext, string action, string controller, object extraRVs, object htmlAttributes) {
//get current optional params from current URL
NameValueCollection c = helper.ViewContext.RequestContext.HttpContext.Request.QueryString;
//put those in a dict
RouteValueDictionary r = new RouteValueDictionary();
foreach (string s in c.AllKeys) {
r.Add(s, c[s]);
}
RouteValueDictionary htmlAtts = new RouteValueDictionary(htmlAttributes);
RouteValueDictionary extra = new RouteValueDictionary(extraRVs);
//merge them
RouteValueDictionary m = RouteValues.MergeRouteValues(r, extra);
return helper.ActionLink(linktext, action, controller, m, htmlAtts).ToHtmlString();
}
这很完美,但我现在添加了 SecurityAware Actionlinks。
所以
return helper.ActionLink(linktext, action, controller, m, htmlAtts).ToHtmlString();
变成
return helper.SecurityTrimmedActionLink(linktext, action, controller, m, htmlAtts);
然后调用:
public static string SecurityTrimmedActionLink(this HtmlHelper htmlHelper, string linkText, string action, string controller, object extraRVs, object htmlAttributes) {
return SecurityTrimmedActionLink(htmlHelper, linkText, action, controller, extraRVs, htmlAttributes, false);
}
public static string SecurityTrimmedActionLink(this HtmlHelper htmlHelper, string linkText, string action, string controller, object extraRVs, object htmlAttributes, bool showDisabled) {
if (controller == null) {
RouteData routeData = htmlHelper.ViewContext.RouteData;
controller = routeData.GetRequiredString("controller");
}
if (IsAccessibleToUser(action, controller)) {
return htmlHelper.ActionLink(linkText, action, controller, extraRVs, htmlAttributes).ToHtmlString();
} else {
return showDisabled ? String.Format("<span>{0}</span>", linkText) : "";
}
}
现在这不起作用。它可以编译,但我的 URL 看起来不太好。
<a count="3" keys="System.Collections.Generic.Dictionary`2+KeyCollection[System.String,System.Object]" values="System.Collections.Generic.Dictionary`2+ValueCollection[System.String,System.Object]" href="/2011-2012/Instelling?Count=3&Keys=System.Collections.Generic.Dictionary%602%2BKeyCollection%5BSystem.String%2CSystem.Object%5D&Values=System.Collections.Generic.Dictionary%602%2BValueCollection%5BSystem.String%2CSystem.Object%5D">Back to List</a>
如您所见,以前有效,现在无效,因为它将RouteValueDictionary
s 作为对象,这没有给我想要的结果。
所以我想,如果我再把它们变成RouteValueDictionary
s 怎么办。
if (IsAccessibleToUser(action, controller)) {
RouteValueDictionary parsedextraRVs = null;
if (extraRVs != null && extraRVs.GetType().Name == "RouteValueDictionary") {
parsedextraRVs = (RouteValueDictionary)extraRVs;
}
RouteValueDictionary parsedHtmlAttributes = null;
if (htmlAttributes != null && htmlAttributes.GetType().Name == "RouteValueDictionary") {
parsedHtmlAttributes = (RouteValueDictionary)htmlAttributes;
}
return htmlHelper.ActionLink(linkText, action, controller, parsedextraRVs == null ? extraRVs : parsedextraRVs, parsedHtmlAttributes == null ? htmlAttributes : parsedHtmlAttributes).ToHtmlString();
}
但这也给了我刚刚在上面发布的网址。为什么这在我的ActionLinkwParams
方法中起作用,但在ActionLinkwParams
调用SecurityTrimmedActionLink
方法时不起作用?我该如何解决这个问题?
