MVC5 中的域路由 [英] Domain Routing in MVC5
本文介绍了MVC5 中的域路由的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我知道有几篇关于类似事情的文章，但没有一篇对我有帮助.
I realize there are a few articles on similar things but none of which has helped me.
我有一个 Web 应用程序，其中多个域指向同一个应用程序.我想知道如何根据尝试访问 Web 应用程序的域将路由映射到特定控制器.
I have a single web app with multiple domains pointing to the same app. I would like to know how I can map a route to a specific controller based on the domain that is trying to access the web app.
我目前尝试的是以下但没有成功.
What I currently tried is the following with no success.
routes.MapRoute(
name: "WowPoetry",
url: "wowpoetry.org/{action}/{id}",
defaults: new { controller = "Wow", action = "Index", id = UrlParameter.Optional }
);
推荐答案
我最终按照本教程来实现我想要的，但我过去常常做域路由而不是子域路由.
I ended up following this tutorial to achieve what I wanted to with the exception of I used to to do domain routing and not subdomain routing.
实施:
routes.Add(new DomainRoute("wowpoetry.org", "", new { controller = "Wow", action = "Index" }));
域数据.cs
public class DomainData
{
public string Protocol { get; set; }
public string HostName { get; set; }
public string Fragment { get; set; }
}
DomainRoute.cs
DomainRoute.cs
public class DomainRoute : Route
{
private Regex domainRegex;
private Regex pathRegex;
public string Domain { get; set; }
public DomainRoute(string domain, string url, RouteValueDictionary defaults)
: base(url, defaults, new MvcRouteHandler())
{
Domain = domain;
}
public DomainRoute(string domain, string url, RouteValueDictionary defaults, IRouteHandler routeHandler)
: base(url, defaults, routeHandler)
{
Domain = domain;
}
public DomainRoute(string domain, string url, object defaults)
: base(url, new RouteValueDictionary(defaults), new MvcRouteHandler())
{
Domain = domain;
}
public DomainRoute(string domain, string url, object defaults, IRouteHandler routeHandler)
: base(url, new RouteValueDictionary(defaults), routeHandler)
{
Domain = domain;
}
public override RouteData GetRouteData(HttpContextBase httpContext)
{
// Build regex
domainRegex = CreateRegex(Domain);
pathRegex = CreateRegex(Url);
// Request information
string requestDomain = httpContext.Request.Headers["host"];
if (!string.IsNullOrEmpty(requestDomain))
{
if (requestDomain.IndexOf(":") > 0)
{
requestDomain = requestDomain.Substring(0, requestDomain.IndexOf(":"));
}
}
else
{
requestDomain = httpContext.Request.Url.Host;
}
string requestPath = httpContext.Request.AppRelativeCurrentExecutionFilePath.Substring(2) +
httpContext.Request.PathInfo;
// Match domain and route
Match domainMatch = domainRegex.Match(requestDomain);
Match pathMatch = pathRegex.Match(requestPath);
// Route data
RouteData data = null;
if (domainMatch.Success && pathMatch.Success && requestDomain.ToLower() != "tg.local" &&
requestDomain.ToLower() != "tg.terrasynq.net" && requestDomain.ToLower() != "www.townsgossip.com" &&
requestDomain.ToLower() != "townsgossip.com")
{
data = new RouteData(this, RouteHandler);
// Add defaults first
if (Defaults != null)
{
foreach (KeyValuePair<string, object> item in Defaults)
{
data.Values[item.Key] = item.Value;
}
}
// Iterate matching domain groups
for (int i = 1; i < domainMatch.Groups.Count; i++)
{
Group group = domainMatch.Groups[i];
if (group.Success)
{
string key = domainRegex.GroupNameFromNumber(i);
if (!string.IsNullOrEmpty(key) && !char.IsNumber(key, 0))
{
if (!string.IsNullOrEmpty(group.Value))
{
data.Values[key] = group.Value;
}
}
}
}
// Iterate matching path groups
for (int i = 1; i < pathMatch.Groups.Count; i++)
{
Group group = pathMatch.Groups[i];
if (group.Success)
{
string key = pathRegex.GroupNameFromNumber(i);
if (!string.IsNullOrEmpty(key) && !char.IsNumber(key, 0))
{
if (!string.IsNullOrEmpty(group.Value))
{
data.Values[key] = group.Value;
}
}
}
}
}
return data;
}
public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
{
return base.GetVirtualPath(requestContext, RemoveDomainTokens(values));
}
public DomainData GetDomainData(RequestContext requestContext, RouteValueDictionary values)
{

};
}
private Regex CreateRegex(string source)
{
// Perform replacements

source = source.Replace("-", @"-?");

}
private RouteValueDictionary RemoveDomainTokens(RouteValueDictionary values)
{
var tokenRegex =
new Regex(
@"({[a-zA-Z0-9_-]*})*.?/?({[a-zA-Z0-9_-]*})*.?/?({[a-zA-Z0-9_-]*})*.?/?({[a-zA-Z0-9_-]*})*.?/?({[a-zA-Z0-9_-]*})*.?/?({[a-zA-Z0-9_-]*})*.?/?({[a-zA-Z0-9_-]*})*.?/?({[a-zA-Z0-9_-]*})*.?/?({[a-zA-Z0-9_-]*})*.?/?({[a-zA-Z0-9_-]*})*.?/?({[a-zA-Z0-9_-]*})*.?/?({[a-zA-Z0-9_-]*})*.?/?");
Match tokenMatch = tokenRegex.Match(Domain);
for (int i = 0; i < tokenMatch.Groups.Count; i++)
{
Group group = tokenMatch.Groups[i];
if (group.Success)
{
string key = group.Value.Replace("{", "").Replace("}", "");
if (values.ContainsKey(key))
values.Remove(key);
}
}
return values;
