I have simple controller code like:
// UserController.groovy
class UserController {
static allowedMethods = [
signIn: 'GET',
authenticate: 'POST',
signOut: 'POST',
register: 'GET',
save: 'POST'
]
// ... code omitted
def register() { }
def save() {
render 'ok'
}
}
Registration form:
<!-- register.gsp -->
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta name="layout" content="main" />
<title>Withme: Register</title>
</head>
<body>
<g:form mapping="register">
<!-- Code omitted -->
<g:actionSubmit value="Register" />
</g:form>
</body>
</html>
And url mappings:
//UrlMappings.groovy
class UrlMappings {
static mappings = {
name register: '/register'(controller: 'user') {
action = [GET: 'register', POST: 'save']
}
}
}
Now for the weird part. When making request with curl all works as expected:
$ curl http://localhost:8080/withme/register -X GET -v -L
... form rendered ...
$ curl http://localhost:8080/withme/register -X POST -v -L
< HTTP/1.1 200 OK
< Server: Apache-Coyote/1.1
< Content-Type: text/html;charset=utf-8
< Transfer-Encoding: chunked

* Connection #0 to host localhost left intact
ok* Closing connection #0
Accessing /register with a browser returns form. But when I submit it within a browser, 405 returned!
HTTP Status 405 -
type Status report
message
description The specified HTTP method is not allowed for the requested resource.
Apache Tomcat/7.0.42
Firebug confirms that POST is performed:
POST http://localhost:8080/withme/register | 405 Method Not Allowed | localhost:8080
I have disabled all filters in my application.
I wonder what the difference between curl and browser POST requests? Why grails handles it in a different way? And finally, how to fix it..

Update
I've figured out that request body matters. Sending request with curl without body succeed, but setting body causes request to fail. Good one:
$ curl http://localhost:8080/withme/register -X POST -v -L

* Trying ::1...
* connected

And bad one:

Still what's the difference?
I've solved strange problem.
Grails renders <g:actionSubmit value="Register" /> as
<input type="submit" value="Register" name="_action_Register">
Note the strange name. Grails deduce it from the value attribute and uses it when choosing what action to call. It causes problem in my case because POST /register should be handled by save action.
Changing it to <input type="submit" value="Register"> solve the problem.
