Grails和子域 [英] Grails and Subdomains

问题描述

Grails是否了解子域名（即subdomain.domain.com）？我没有在手册中看到它的讨论。这纯粹是一个应用程序服务器/ Web服务器的问题？可以绑定到grails控制器，无论是静态还是动态？

解决方案

无论哪个主机访问java web应用程序。

1. 假设您在一台主机上分隔了多个客户端，例如customer1.yourhost.com，customer2.yourhost.com等，所有的客户端都具有相同的功能。
   
   

   在最简单的例子中，我只是用写过滤器，它总是会放一些请求变量，如下所示：

     def filters = {
    all（controller：' （'。'））{
    def clientName = 
    request.serverName。 substring（0，request.serverName.indexOf（。））
    
    request.currentClient = Client.findByClientName（clientName）//例如
   } 
   } 
   } 
   } 
     

   然后在任何地方你可以检查 request.currentClient 为当前访问的子域。

   
   
   

   然而，如果它变得更复杂看看Grails的一些多租户插件。

如果你想为每个子域拥有不同的功能，例如help.yourhost.com和www.yourhost.com，我会建议你编写独立的Grails应用程序。然后，您可以设置NGINX服务器，将这些请求重定向到应用服务器上运行的相应应用程序。

Does Grails know anything about sub-domains (i.e. subdomain.domain.com) ? I don't see it discussed in the manual. Is this purely an app server/web server issue? Can be tied into grails controllers, either statically or dynamically?

解决方案

It does not matter which host is accessed for a java web application.

1. Supposing you have multiple clients separated on one host, e.g. customer1.yourhost.com, customer2.yourhost.com, etc. and all clients will have same functionalities.

   In the simplest case I propse, that you just use write a filter, which will always put some request variable, like this:

   def filters = {
       all(controller:'*', action:'*') {
           before = {
               if (request.serverName.contains(".")) {
                   def clientName = 
                     request.serverName.substring(0, request.serverName.indexOf("."))
   
                   request.currentClient = Client.findByClientName(clientName) // e.g.
               }
           }
       }
   }
   

   Then at any place you can check request.currentClient for the current accessed subdomain.

   However if it gets more complicated have a look at some multi-tenant plugins for grails.

2. If you want to have different functionalities for each subdomain e.g. help.yourhost.com and www.yourhost.com, I would propose that you write independent grails applications. You then setup a NGINX server to redirect those requests to the appropriate application running on your application server.
