Question

Given this UrlMapping:

'/foo/$foobar' {     controller = 'foo'     action = 'foo'     constraints {     } } 

Combined with this controller:

class FooController {     def foo = {         def foobar = params.foobar         println 'foobar=' + foobar     } } 

And with these requests:

• http://localhost:8080/app/foo/example.com give the output ‘foobar=example’
• http://localhost:8080/app/foo/examplecom give the output ‘foobar=examplecom’

It seems like Grails cuts the ‘foobar’ parameter at the first dot (‘.’). Is this intentional? Is there a work-around if I want to use parameters containing dots in my URL mappings?

Answer 1

This can be solved by setting …

grails.mime.file.extensions = false 

… in Config.groovy.

It seems like Grails is trying to do some MIME magic behind the scene based on the file name suffix.

Updated: Some additional info from the Grails JIRA.

This is the offending code in UrlMappingsFilter.java:

    if(WebUtils.areFileExtensionsEnabled()) {         String format = WebUtils.getFormatFromURI(uri);         if(format!=null) {             MimeType[] configuredMimes = MimeType.getConfiguredMimeTypes();             // only remove the file extension if its one of the configured mimes in Config.groovy                                                                                                                        for (MimeType configuredMime : configuredMimes) {                 if (configuredMime.getExtension().equals(format)) {                     request.setAttribute(GrailsApplicationAttributes.CONTENT_FORMAT, format);                     uri = uri.substring(0, (uri.length() - format.length() - 1));                     break;                 }             }         }     } 

WebUtils.areFileExtensionsEnabled() returns the value of the ‘grails.mime.file.extensions’ setting configured in Config.groovy.
