I have a rest web service built with the Visual Studio wizard with a method like this:
public string Post([FromBody] string value)
{
...
}
and another parameterless one (provided by the wizard) like this:
public IEnumerable Get()
{
...
}
I have installed this in two separate locations on the web.
I can call the parameterless Get method and the FromBody Post method directly on each location from a .net console app and from a smartphone app with no problem. I may sometimes need to forward calls made to one location on to the other and this is where the problem comes. I find if I call the Post(FromBody) method on the service being forwarded that it is received by the location to which it has been forwarded without the parameter and so the second wizard generated parameterless method receives it by default.
I am using the RestSharp NuGet package.
The service being fowarded is being managed by Google domains and in the forwarding process I have specified the path to be included in the forwarding.
Is there some additional setting I need to specify in the calling code that will ensure that the FromBody parameter is passed on to be picked up by the ultimate destination rather than being discarded?
Any thoughts anyone has would be very welcome.
I was expecting the FromBody parameter to be passed on as part of the forwarding process

My Problem: I want to introduce a new field in JIRA with status information from external REST Service (response is json).
Plan: Every Jira issue has a input field with some reference string. Behind this field there should be a panel, what should display informations from the external REST call (parsing response JSON is required).
Can someone give me some good info pages, how to tell JIRA to call external REST Service?
If you don't want to build it see:
nFeed
HTTP Feed Custom Field
If you want to build it yourself then start by following this tutorial on Creating a custom field type which is to more or less store a basic String within the database. (This would be the reference string)
You then have two options, the first is within the JiraCustomField class override the getVelocityParameters which was taken from How to call a java method from velocity Atlassian Answers question.
Then create a method (fetchValueFromWebService(String val)) that you would call that would contain code to query the REST Service based off the fields value that would be passed in from the velocity template. (E.g. $instance.fetchValueFromWebService($value))
To perform the actual web service call you can use any library you want, just see the Managing Dependencies documentation so it gets included in the plugin. (For example using the Jira Jersey version see this)
Your other option would be to within the view-basictext.vm have it use javascript and perform an AJAX to the web service by calling a function in your own JS file and dump that into a span that you have defined: (See Including Javascript and CSS resources)
<span id="webServiceValue"></span>
<script type="text/javascript">
fetchValueFromWebService($value);
</script>
You would however need to ensure that the webservice has Cross-origin resource sharing (CORS) enabled if you go the AJAX route.
I've created the blog from blog tutorial, and I would to protect articles list, but I want that this be accesible across REST, I've activated json extensions.
All works well. I can add and retrieve list, but now I want to deny index and add from web and only be accesible from .json to public.
I tried with
public function beforeFilter(Event $event)
{
parent::beforeFilter($event);
$this->Auth->allow('index.json');
}
But this obviously doesn't work. All webpage is login protected as is in tutorial. Web services should be accesible to Android App (code is ready and working).
Thank you!
Of course that doesn't work, the allow() methods expects valid method names, and that's all the authentication component cares about, method/action names, it doesn't matter how the action was requested.
What you are trying to do requires you to check the type of the request, and based on the results, allow the actions. Checking the request type can be done using Request::is().
See Cookbook > Request & Response Objects > Checking Request Conditions
So it might be as simple as
if ($this->request->is('json')) {
$this->Auth->allow(['index', 'add']);
}
I just started to learn Grails and my question of this could be dumb. So apologies if it is dumb. I have a client program and a REST web service - both coded by me. The client program calls the RESTful service using POST (to add record to a database). When I call object.save() there are some validation errors that are returned.
In my gsp I have fieldError tag coded to read the error message for each field in the bean and show it in the screen. I'm assuming I needed to pass the domain instance that failed the validation from RESTful service to the client so the client could inturn send it to gsp which will automatically show errors. Correct me if this is wrong. however I don't know how to pass the domain instance object as XML from the web service. When the validations are successful though, I get the object like "render object as XML". However when validations fail, I don't know how to pass the entire failed domain instance object back as xml.
I tried to code,
if (student.save()){
render student as XML
} else {
student.errors.each(){
println it
}
def errmsg = student.errors.allErrors.collect { g.message(error:it) }
render(contentType:"text/xml") {
respstud {
for(err in errmsg) {
message(err)
}
}
}
}
This returned the specific error message back to the client as xml, but I'm needing the entire student object to be sent back to the client when save() fails also. Can someone please help?
let me know if you need more info. This is my first post in stackoverflow so I don't really know if I have to provide more details. Any help is greatly appreciated.
Thanks,
Prem
Because the request is being made via ajax, you will need to handle it the Ajax way.
Your gsp is compiled on the server and sent as html to the client when the page is first requested.
One way to handle this would be to set an error on the ajax response and return a snippet of the code you would like to render.
The response may then be handled in the error section of your calling JavaScript and the code snippet rendered on the page where you wish.
I have two questions:
Q: 1
I'm currently developing a GWT app. The entry point for the app is: ImageViewer.java. I could well access it by http://127.0.0.1:8888/ImageViewer.html?gwt.codesvr=127.0.0.1:9997. I have a service called "Search" which has corresponding "Async" and "Impl"'s defined. Now, I call the service from client side, using RPC. I could call the service, obtain return value. Everything works fine.
However, I expect the application to show a behavioral change on URL. i.e. when a service is being accessed, I thought it would be reflected on the browser's URL something like: http://127.0.0.1:8888/search?gwt.codesvr=127.0.0.1:9997 as I've modified web.xml. However, this behavior is not realized. Any particular reason why this is not reflected??
Q:2
This one is a reverse of the previous ques. i.e. I have an application running. Let's say it has an entrypoint class(Imageviewer.java) and another composite class (searchClass.java) which would be loaded on the Imageviewer based on an event. This searchClass invokes the "search" service mentioned in the previous question.
I could load the "searchClass" in "Imageviewer", invoke the service, and the service also returns the value needed. Everything works fine... But,
I need something like this: by just typing this query string:
http://127.0.0.1:8888/search?value=John
I want the "searchClass" to be loaded on the "ImageViewer", call the service using the value(which is "john" in this case) and display the result. Is this possible at all?
what I've tried: I have tried to create a httpServletClass on the server and mapped it with the URL and could do the search. The search returns appropriate results. However, I want the results from the server to be displayed on the client. Remember, I'm directly using a servlet to read the URL and so there is no value being passed from client to server.
Thanks in advance.
A: 1. To change URL, the hash part, you need to set new history token in the History class. More about history management in this article.
A: 2. For the second part you could achieve it by changing the history token, for instance "http://127.0.0.1/search#value=John". The history service will trigger an event if the # part changes. You could also use the part with "?", as in your example, if you use Window.Location , but it will cause reload of the application, which would put the whole idea of using GWT in question.
RPC (AJAX) calls are done Via XHR and do not change the browser URL.
You can't (with the URL you presented). GWT apps normally run in one web page, i.e. the URL does not change (see how gmail changes browser url bar). What you can do is enable GWT history support. Then your url would be http://host/#search?value=queryu
Is there a comprehensive explanation of how the Zend Redirector Action Helper works? I've read the reference guide, but am still not 100% clear. For example:
Apparently the goToSimple() is more like a forward(), than a redirect. Does this mean that it won't send a redirect message back to the browser?
If I want to send a redirect message back to the browser, which Redirector method should I be using?
Is there a way to get the forward() type of behaviour, without re-executing the init() method of Action Helpers?
This problem cropped up when I was implementing an ACL. I have an ACL Action Helper and its init() method adds the role 'current'. When I use the redirector's goToSimple() I get an error saying that the role is already registered. I can use if (!$acl->hasRole('current')) however I think it would be preferable not to be re-executing the helper's init() in the first place.
Not too comprehensive just a few quick notes about the redirector.
The redirector does a little bit more than a regular PHP redirect which you would use with header('Location: www.domain.com/new/location') in your script--following by an exit().
If you look at Zend_Controller_Action_Helper_Redirector it ultimately does exactly the same; if $_exit==true (default) everything leads to redirectAndExit() which calls header() and ends with an exit() call. However it terminates the framework properly, mainly the session if any.
The redirector does not forward internally it sends a default 302 code back unless you have set another code with setCode().
Methods gotoRoute() and gotoSimple() assemble the destination URL for you and call redirectAndExit() but only if $_exit==true. Or you can use their brethren gotoRouteAndExit() and gotoSimpleAndExit() which will exit immediately. The gotoSimple methods pass on to setGotoSimple which uses some methods to assemble the URL for you.
In your case I can only assume that the setGotoSimple method and one of the methods in it call the destination controller and fire up the init() method; however, only for checking but not forwarding.
