why asp .net mvc web api does not support custom operations? - visual-studio-2010

I don't know if I am missing something obvious.
I can see that asp .net web api supports standard Get(), GetById(), Add, Update, Delete operations. But it does not support some custom operations/actions like for example "Get_CustomDataForModel", "Do_SomePostWork" or "Do_somecalc_and_return_a_list" any such custom operations.
I have tried searching for this question, but couldn't get a direct answer. If this is a duplicate, pls give me the right link.
Is this because HTTP REST requests must only support one method each per url for GET, POST, DELETE, PUT etc.,?
Am I missing something obvious while it supports it and I don't see it?
Is there a way to add let's say 30 different actions with 15 get and 15 posts? (PS: I know having 30 actions inside a controller is a bad idea, but asking just for the sake of understanding)

By default, Web API supports HTTP method based routing. But it does support RPC-style routing based on action methods. Look at the section "Routing by Action Name" in http://www.asp.net/web-api/overview/web-api-routing-and-actions/routing-in-aspnet-web-api. BTW, it is possible to have 30 different action methods in a controller but won't it be a maintenance nightmare?

Helpme with own functions in api-platform

recently I have been working with symfony 4 in search of some solution for the creation of web services api-rest and I have found api-platform. After several days trying, because I do not have much knowledge of symfony, I managed to raise the API for an entity that I created by default. It turns out that now I have the doubt of how to add to the api methods other than those that are by default, say the put, the get and others that are already by default, I want to be able to add to my entity the methods that I estimate necessary and with the name that I want. Please I would appreciate your help with some form or some simple steps that allow me to add new methods to the api always keeping in mind that I do not have much knowledge in the matter.
try to avoid endpoint proliferation as much as possible, think REST
the recommended way to hook your own logic in API Platform is using the built-in events
if you really need to add custom endpoints, here is a dedicated documentation entry, but it should be your last resort (see 1/)

Laravel Web and API controller structure. Separate vs DRY

I want to build a Laravel application which users both web and API parts. The common (and mine as well) question is whether to use separate controllers or not.
There are 2 options:
Separate controllers
Laravel API controller structure?
Use one controller and check the request type (is Ajax, or depending on the request link) and return either JSON or HTML.
Laravel resource controllers for both API and non-API use
Those who have the 1-st opinion doesn't explain the DRY problem solution - web and API controllers would be the same except the return statement (JSON or HTML view). But since most post recommend to separate controllers I suspect I don't understand something about the DRY problem solution.
I don't see any disadvantage of the second method. But people say something like
If you use only one controller, you will end up soon with a messy class with thousands of lines. Not only this is not going to scale well, but it will be hard to work with for you and your teammates.
Please explain me the DRY problem solution for the first approach (separate controllers) and the possible underwater rocks in the second approach (single controller)
Please explain which approach is preferable.
I think this is a great question, and I too am keen to see the responses.
I can see the arguments for both approaches. I however would create and maintain separate controllers, whilst using services to share common logic between the controllers where it is known that this will never change.
For example, if you allow users to upload avatar images. I would put such logic in a service and consume this service in both controllers.
The reason for this approach in my mind, is that the web and API logic may diverge and it would therefore be easier to iterate each without impacting the other.
If this is unlikely, then I would still create separate routes, but point them both at the same controllers, so that if it did change in the future, you can simply re-point the API routes to their own controllers.

Grails - execute check on every request

I’m looking for a neat way to execute a check to see if there are any messages in an inbox (realtime) in a Grails 2.x application.
I’ve moved away from polling via ajax to websockets, which is great at the point where someone actually sends you the message, but when you change to another screen, the “count” still needs to be initialized.
Can anyone advise on a elegant way of doing this?
Interceptors are not ideal as I need to check across just about all controllers
Filters are not ideal because on some screens with graphs there are many ajax request, the check would be run many times for each request.
I’m wondering if there are any other solutions that I’m not thinking of.. but possibly not.
A filter that disregards the check if a request header indicates an Ajax request would work.
Depending on where you need this "count" you could: In your layout (main.gsp for instance) call a tag library which makes use of a service to fetch the count. That way it's only applied to GSPs where the layout is applied (e.g. not any ajax request).

phplist api - subscibe / edit / remove users by ajax

I have a very-simple php-based website.
I would like to add "subsribe for information" box and send it to some list-management tool.
I found that phplist is quite a good one. However, I don't find any api which allows me to subscribe users using ajax.
(I would like to avoid the pages of phplist in order to avoid confusion due to different design, and also I want the interface to be multi-language).
Of-course I can touch the code, but I doubt that it misses this feature, so I assunme I simply missed it.
Thanks!
Hopefully you have managed how to achieve this already. I have a different use case not requiring AJAX.
Anyway, I've found a script that tries to ease the addition of subscribers to your list. Maybe you could use it as the backend to support your AJAX request.
This is the thread in which the script is shared, as others have found it useful, also for unsuscribing users, even handling massive subscriptions/unsuscriptions:
http://forums.phplist.com/viewtopic.php?t=5009
Finally, be aware this code is using PEAR DB abstraction layer, probably I'm going to use this but without the PEAR package.
I look forward for what you could do through AJAX and this functions.

Why use MVC/router

I'm trying to comprehend the concept behind MVC and URL routing. I understand that it's good to seperate your code, hence MVC, but fail to understand the idea behind the URL router!
Instead of having a lot of rewrite rules in htaccess, I send all traffic to router.php, and in this page I have an array with page urls, and its corresponding PHP controller.
To keep it simple, I just include the controller, where the output finally is generated, however having seen lots of other practices, I'm afraid that im doing something wrong, or bad in some way..
Can someone please enlighten me, how to do a good, but simple URL router? Is it okay just to include the controller, which then generates the output? Perhaps someone has some information that describes the subject in details (something understandable for a beginner)
Thanks in advance
There are lots of ways to do URL routing. Some are client side like with backbone.js, others are server side. Doing it with .htaccess is one way, another is th way you are doing it by having a prerequisite path that is is either a hard path, or a regular expression that you parse and figure out where to send it. None of them are 100% right or 100% wrong, it's all preference, and it sounds like you are doing just fine with a route file.
For more information on how different frameworks do routing you should read over the docs on routing for CodeIgniter, and Symfony frameworks to see 2 different styles of server side routing, and then maybe look at the backbone.js framework for client side routing just to see the similarities and differences.
The router in the MVC concept decides which controller it has to load when a user requests a page. E.g. a user requests example.com/something/very/important, the router would now look for an action which is mapped to this route and execute it. There are different methods how you can accomplish that (simple include, instantiating a class and running a method etc.) but the most simple and still powerful solution I came up with is creating a separate class for every action. I've written a little article on that matter, since I've been asked this question several times, you can have a look at it here: Writing a simple and fast mvc router with PHP
The ASP.NET Routing module is responsible for mapping incoming browser requests to particular MVC controller actions.
Routing is a pattern matching system that monitor the incoming request and figure out what to do with that request. At runtime, Routing engine use the Route table for matching the incoming request's URL pattern against the URL patterns defined in the Route table. You can register one or more URL patterns to the Route table at Application_Start event.
