URLs with slash in parameter?
提问by Stefan Steiger
Question:
题：
I am creating a wiki software, basically a clone of wikipedia/mediawiki, but in ASP.NET MVC (the MVC is the point, so don't recommend me ScrewTurn).
我正在创建一个 wiki 软件，基本上是 wikipedia/mediawiki 的一个克隆，但是在 ASP.NET MVC 中（MVC 是重点，所以不要推荐我 ScrewTurn）。
Now I have a question:
现在我有一个问题：
I use this route mapping, to route a URL like:
http://en.wikipedia.org/wiki/ASP.NET
我使用这个路由映射来路由一个 URL，如：http:
//en.wikipedia.org/wiki/ASP.NET
routes.MapRoute(
"Wiki", // Routenname
//"{controller}/{action}/{id}", // URL mit Parametern
"wiki/{id}", // URL mit Parametern
new { controller = "Wiki", action = "dbLookup", id = UrlParameter.Optional } // Parameterstandardwerte
);
Now it just occured to me, that there might be titles like 'AS/400':
http://en.wikipedia.org/wiki/AS/400
现在我突然想到，可能有像“AS/400”这样的标题：http:
//en.wikipedia.org/wiki/AS/400
Incidentially, there is also this one (title 'Slash'):
http://en.wikipedia.org/wiki//
顺便说一句，还有这个（标题“斜线”）：http:
//en.wikipedia.org/wiki//
And this one:
http://en.wikipedia.org/wiki//dev/null
还有这个：http:
//en.wikipedia.org/wiki//dev/null
Overall, Wikipedia seems to have a list of interesting titles like this: http://en.wikipedia.org/wiki/Wikipedia:Articles_with_slashes_in_title
总的来说，维基百科似乎有一个像这样有趣的标题列表：http: //en.wikipedia.org/wiki/Wikipedia: Articles_with_slashes_in_title
How do I make routes like this route correctly ?
我如何正确地制作这样的路线？
Edit:
Something like:
If the URL starts with /Wiki/, and if it doesn't start with /wiki/Edit/
(but not /Wiki/Edit)
then pass all the rest of the URL as Id.
编辑：
类似于：
如果 URL 以 /Wiki/ 开头，并且不以 /wiki/Edit/ 开头（但不是 /Wiki/Edit），则将 URL 的所有其余部分作为 Id 传递。
Edit:
Hmm, just another problem:
How can I route this one:
http://en.wikipedia.org/wiki/C&A
编辑：
嗯，只是另一个问题：我如何路由这个：http:
//en.wikipedia.org/wiki/C&A
Wikipedia can...
维基百科可以...
Edit:
According to wikipedia, due to clashes with wikitext syntax, only the following characters can never be used in page titles (nor are they supported by DISPLAYTITLE):
编辑：
根据维基百科，由于与 wikitext 语法的冲突，只有以下字符永远不能用于页面标题（DISPLAYTITLE 也不支持它们）：
# < > [ ] | { }
Edit:
To allow * and &, put
编辑：
为了允许 * 和 &，把
<httpRuntime requestPathInvalidCharacters="" />
into section <system.web> in file web.config
进入文件 web.config 中的 <system.web> 部分

You could use a catchall route to capture everything that follows the wikipart of the url into the idtoken:
您可以使用笼统的路由wiki将 url 部分后面的所有内容捕获到id令牌中：
routes.MapRoute(
"Wiki",
"wiki/{*id}",
new { controller = "Wiki", action = "DbLookup", id = UrlParameter.Optional }
);
Now if you have the following request: /wiki/AS/400it will map to the following action on the Wikicontroller:
现在，如果您有以下请求：/wiki/AS/400它将映射到Wiki控制器上的以下操作：
public ActionResult DbLookup(string id)
{
// id will equal AS/400 here
...
}
As far as /wiki//is concerned I believe you will get a 400 Bad Request error from the web server before this request ever reaches the ASP.NET pipeline. You may checkout the following blog post.
至于/wiki//来讲我认为这个要求是以往任何时候都达到ASP.NET管道，你会得到从Web服务器400错误请求错误。您可以查看以下博客文章。

in Attribute Routingin mvc i had the same problem having /in string abc/cdein HttpGet
在Attribute Routingmvc 中，我/在字符串abc/cde中遇到了同样的问题HttpGet
[Route("verifytoken/{*token}")]
[AllowAnonymous]
[HttpGet]
public ActionResult VerifyToken(string token)
{
//logic here
}
so you have to place *because after this it will be considered as parameter
所以你必须放置，*因为在此之后它将被视为参数

@Darin: Well, that much is obvious, the question is: Why ? controller + action + id are given, it's like it's passing all these to routing again... – Quandary Jun 13 '11 at 17:38
@Darin：嗯，这很明显，问题是：为什么？给出了控制器 + 动作 + id，就像它再次将所有这些传递给路由... – Quandary 2011 年 6 月 13 日 17:38
Quandry - maybe you have already figured this out since your question is over a year old, but when you call RedirectToAction, you are actually sending an HTTP 302response to the browser, which causes the browser to make a GET request to the specified action. Hence, the infinite loop you are seeing.
Quandry - 也许您已经想通了，因为您的问题已经存在一年多了，但是当您调用 RedirectToAction 时，您实际上是在向浏览器发送HTTP 302响应，这会导致浏览器向指定的操作发出 GET 请求。因此，您看到的无限循环。

Still as an option write in the file Global.asax:
仍然作为选项写入文件 Global.asax：
var uri = Context.Request.Url.ToString();
if (UriHasRedundantSlashes(uri))
{
var correctUri = RemoveRedundantSlashes(uri);
Response.RedirectPermanent(correctUri);
}
}
private string RemoveRedundantSlashes(string uri)
{
const string http = "http://";
const string https = "https://";
string prefix = string.Empty;
if (uri.Contains(http))
{
uri = uri.Replace(http, string.Empty);
prefix = http;
}
else if (uri.Contains(https))
{
uri = uri.Replace(https, string.Empty);
prefix = https;
}
while (uri.Contains("//"))
{
uri = uri.Replace("//", "/");
}
if (!string.IsNullOrEmpty(prefix))
{
return prefix + uri;
}
return uri;
}
private bool UriHasRedundantSlashes(string uri)
{
const string http = "http://";
const string https = "https://";
if (uri.Contains(http))
{
uri = uri.Replace(http, string.Empty);
}
else if (uri.Contains(https))
{
uri = uri.Replace(https, string.Empty);
}
return uri.Contains("//");
}
