URL Routing
All modules have the capability to leverage URL routing in a portable manner. They will automatically register an entry point URL pattern via the
this.entryPoint setting. If an incoming URL has that specific pattern, then it will search for the module's routing table for a match.this.entryPoint = "/mymodule";
You can also add these entry points manually in the host application's routing file:
config/Router.cfc. However, you will lose all module portability. We do this by using a method called addModuleRoutes() method.addModuleRoutes(pattern, module): Insert the module routes at this location in the configuration file with the applied URL pattern.
The URL pattern is the normal URL Mappings pattern we are used to and the module is the name of the module you want to target. What this does is create an entry point pattern that will identify the module's routing capabilities. For example, we create the following:
addModuleRoutes(pattern="/blog",module="simpleblog");
addModuleRoutes(pattern="/admin",module="admin");
What the previous method calls do is bind a static URL entry pattern to a module. So if the framework detects an incoming URL with the starting point to be /blog, it will then match the simpleblog routes. Once matched, it will now try to match the rest of the incoming URL with the module's custom routes. Let's do a full example, below are some custom routes for my blog module in its
ModuleConfig.cfc:// In my ModuleConfig.cfc
routes = [
{pattern="/", handler="blog", action="showPosts"},
{pattern="/:year-numeric/:month-numeric?", handler="blog", action="showPosts"}
{pattern="/comment/:action", handler="comments"}
]
Now, let's say the URL that is incoming is:
http://mysite.com/blog
Then this will resolve to the
/blog pattern in the host that says, now look in the module simpleblog for routes. The left over part of the URL is nothing or / so the pattern that matches is my first declared pattern:{pattern="/", handler="blog", action="showPosts"}
This means, that we will execute the modules'
blog handler and the showPosts method. Now, let's say the next URL that comes is:http://mysite.com/blog/2009/09
Then this will match the
simpleblog module via the static /blog entry point and then it tries to find a match for /2009/09 in the modules' routes and it does!Last modified 3mo ago
