I have requirement of changing GET to POST redirection to external URL.
Currently, we are using checkFormRedirect(url,req,res) to redirect to external URL which by default uses GET as per my understanding. I want to change this request to POST.
One way is we can use HTTPClient API for re-direction.
Is there any way ATG out of box provide some thing to POST redirection. Please help.
If you submitted a form in JSP as you are using checkFormRedirect(). It is already a POST request and you can get data in your handlerXXX method.
You can use this method to control redirects. The API call of this method looks somewhat like:-
public boolean checkFormRedirect(pSuccessURL, pFailureURL, pRequest, pResponse);
Now, this method redirects to pSuccessURL if no form errors are found in the form. Otherwise, it redirects to pFailureURL.

Does anyone know how to pass parameters to a RESTFUL webservice using the Orbeon HTTP Service?
I have a RESTFUL API at http://localhost/RESTFUL/GETADDRESS/$parameter$.
Sample of the URL is http://localhost/RESTFUL/GETADDRESS/1234
Orbeon HTTP service is unable to pass the parameter to the web service.
The Request Body is configured as <parameter/> and serialization is set to XML.
Could not use HTML Form as it adds a ? to the URL which is not correct.
Anyone has any ideas to get this working?
There is no perfect solution. But try writing the service URL as:
http://localhost/RESTFUL/GETADDRESS/{...expression here...}
where "...expression here..." should be replaced by an XPath expression pointing to the value you would like to pass. For example, if pointing to a control called foo in a section called bar, try:
http://localhost/RESTFUL/GETADDRESS/{/*/bar/foo}
I also added this RFE.
Suppose I have URL as
http://someurl.com/Search?q=a&page=8
(Above mentioned URL is getting called throug AJAX, in MVC4.paging)
What I want is to show only upto http://someurl.com/Search?q=a
I want to hide my second parameter which is page=8
Is this possible?
EDIT: More confusion to add.
<a data-ajax="true" data-ajax-loading="#divLoading" data-ajax-method="POST" data-ajax-mode="replace" data-ajax-success="successPaging" data-ajax-update="#searchresults" href="/Search?q=a&page=1" title="Go to first page"><<</a>
Is button of Next in my Paging, it is making an AJAX request, So I don't know how to change GET to POST for this.
The URL isn't there just for looks; it's telling the server what resource is being requested, and in the case of a query string, that's information the server needs to return a response. http://someurl.com/Search?q=a is a completely different resource than http://someurl.com/Search?q=a&page=8. With a GET request, all you have is the URL, so all the information the server needs must be in the URL. What others in the comments are telling you to do is use a POST request, which among other things includes a post body. In other words, you can pass information to the server both in the URL and in the post body. That allows you to remove the page parameter from the URL and include it in the post body instead. That's the only way you can achieve what you want.
That said, strictly speaking, a POST is inappropriate for fetching a resource like this. POST should be used to update or modify a resource or to call some atomic method in an API scenario. It can also be used for the creation of resources, although PUT is more appropriate there. GET is supposed to be used to return a resource which is not variable. For example, any request to http://someurl.com/Search?q=a&page=8 should always return the same response no matter what client requests it. And, it's even less important what URL is actually being used because the user does not see it at all, since you're requesting it via AJAX (it won't show in the navigation bar). Just keep it as a GET request and leave the parameters as they are.
I run my scripts under Apache. I understand how I can create request, for example:
http.Get(url)
How I can get GET request? I really dont see this information in docs. Thanks in advance!
UPD
For example, i do GET or POST-request to my go script from another script. In PHP I'd just write $a=$_GET["param"]. How i can do that in Go? Sorry for bad english, by the way
Your handler is passed a Request. In that Request you find for example the parameters in the Form field as soon as you parsed it using ParseForm :
// Form contains the parsed form data, including both the URL
// field's query parameters and the POST or PUT form data.
// This field is only available after ParseForm is called.
// The HTTP client ignores Form and uses Body instead.
Form url.Values
I would like to be able to log the requests that my app receives that are unauthorized. Because the Shiro plugin uses an HTTP redirect to send the user to auth/unauthorized the request object is a fresh one and I can't get the original URL; controller/action name; or request parameters from it.
Is there a way to determine either the original url, or the controller and action names (and request params if possible) inside the AuthController unauthorized action?
I am looking at http://plugins.grails.org/grails-shiro/tags/RELEASE_1_1_3/ShiroGrailsPlugin.groovy as a reference of the plugin source.
Details:
Grails 1.3.7
Shiro Grails plugin 1.1.3
I had the same problem... my solution is not perfect:
a browser sends the so called referer in one of the headers which you can get through
request?.getHeader('Referer')
But the referer is nothing you really can rely on -- but most of the browsers send it.
Another solution could be the filter: try to write the current url to another variable before you call accessControl() in ShiroSecurityFilters.groovy. You can get the current URL through request.forwardURI.
Update: just verified my last assumption - this seems the cleanest solution to me:
In ShiroSecurityFilters.groovy, replace
// Access control by convention.
accessControl()
with
// Access control by convention.
if (!accessControl()) {
session.deniedUrl = request.forwardURI
return false
}
which enables you to access the url as session.deniedUrl in your auth/unauthorized controller.

What are the benefits to send data with internal requests like this
$post = Request::factory('module/data')
->method(Request::POST)
->post(array('some' => 'random data'))
->execute()
->response;
if you could simply send data like this
Module::instance()->data(array('some' => 'random data'));
In this example Module is a random module and data is some random method.
I'll call this Module via ajax and internal requests. I'm planning to design RESTful API.
QUESTION IS: Why use HMVC instead of just directly using an internal class API
Because they're internal requests, there is no additional HTTP request being made.
You might want to take a look at Request_Client_Internal and compare it to Request_Client_External. After that you should feel enlightened :)
Edit:
You should know that AJAX requests aren't the only "external HTTP requests". cURL, PECL HTTP, file_get_contents() and other PHP functions will also send an external HTTP request (imho you should read the RFC 2616 to understand how HTTP actually works).
With HMVC calls you can use the same controller for both Ajax and internal requests. Also, it can handle a standard (non-ajax) http-requests, form submits for example. All-in-one solution, single entry point.
If you dont want HMVC calls, you will require one call for internal request (somewhere in base controller) and another one - in a special Ajax controller. Also you may have a problems with a data rendering (usually HMVC and ajax calls are using different templates). Its not DRY.
I would comment on the above, what biakaveron said, but I can't yet, so I put it as an answer.
#stacknoob: Could you use Module::instance()->data(array(...)) as controller's action? You could - with some extra code.
Instead, what biakaveron already said, you can keep your code logic and have the action return the same result for AJAX and HMVC requests. In one place. DRY + KISS.
