Hi I am new for nopcommerce 3.5. I need to write a restful web service api to third party(for eg mobile) access the service. I know that we can access through Nop.Plugin.Misc.WebServices . I had enable the service from administrator site.
But now is my question. How can i call the web service for eg GetPaymentMethod , product list and etc
And if I want to write my custom web service by using web api. what is step to create? I cant find any documentation about the web service. Please guide me some example
Thanks
If you want a really quick start in writing a web service in NopCommerce, you can follow the MVC architecture and:
Create an Action method inside a Controller that you find appropriate for your purpose. For example, if you want access to a product list, you might create an Action inside CatalogController that follows the logic of the existing ProductList action.
Set up a Route in RouteProvider.cs to point to the Action you created. Based on this route you can deduce the URL of your service.
Do the processing that you need inside the Action. If this Action/service is to be called with parameters (in query string format: param=value¶m2=value2), you can just put these parameters in the Action's header:
public ActionResult QuickService(int param, string param2) { ... and .NET will take care of having them initialized.
Store results in an object (can also be an anonymous object) and at the end of your action, return it as Json: return Json(resultsObject); Again, ASP.NET takes care of the JSON serialization and automatically sets the Content-Type HTTP response header to "application/json".
You can consume the service calling the URL that corresponds to the route of your Action.
If you want users to be able to log in, by using the above method, it gets a little bit trickier. You need the webservice client to be able to accept and send cookies, as well as make appropriate services for Login, Logout, Register,...
However, in this case, you might be better off with a mobile version of the site.
Final note: If you don't want to alter base NopCommerce code, you can apply the steps above to a plugin. The majority of NopCommerce plugins follow the MVC architecture, so you can apply the steps above.

Do any of the front end frameworks (Like Vue.js) have the ability to generate a prototype form/view directly from various an Endpoints?
I am wanting to quickly knock up a few forms to capture and submit data to a set of JSON Rest Post APIs and Display pages to render data retrieved from other JSON Rest Get APIs.
I don't want to have to go through the pain of having to map each and every field out in a set of .js file, it would be great if the boilerplate could just be generated from interface in a similar way to what Apache Isis does from a Domain model.
The above would allow me/clients to generate a UI directly off the interface and interact with it using a web browser in a similar way one would using Postman, without having to install and understand Postman.
You can try one of these:

I am total JS newbie working on a project build in Grail 2.4.4, a web-app. It's a working app, build by a developer whom is not available anymore.
To get it to work locally I had to upgrade it to Grails 3.2.0. I got it almost working in Netbeans. But I got stuck at getting the data from the MySQL database.
The Chrome inspector says:
angular.min.js GET http://localhost:8080/<app>/currency/allCurrencies 404 ()
The controllers are written in Restangular which call the above URL.
What am I missing?
Firstly, Restangular is an Angular library which simplifies and standardizes making calls to a REST backend (which in your case is a Grails app). So, Restangular does not directly retrieve data from your a database, it invokes a web service which (in some cases) may retrieve data from a database.
In your case, Restangular is attempting to retrieve data from the endpoint http://localhost:8080/<app>/currency/allCurrencies but you are getting a 404 response, indicating that there is no endpoint mapped to this URL.
HTTP REST helps you connect to the API easily. Restangular can handle that by sending standard methods [Get, Post, Delete, Put] to the api like what you see.
This mean StudentController > Get()
localhost:2045/api/student
This mean StudentController > Get(Guid id)
localhost:2045/api/student/8ae37cfa-905b-4c71-ad03-bf416d93bdf8
This mean StudentController > POST(Guid id) ... if you send Post method to the API, it will detect it, this work also on put method
localhost:2045/api/student
use this module to get easily rest api.
Http-Rest-Service
I've been looking into if it's possible to create a web based version of my Chrome Plugin
now that it's relying completely on Trakt.TV's JSON API.
According to angular's documentation, it's possible to intercept HTTP requests at several levels, one is the HTTP Backend itself (mainly used for testing though) and the other is HTTPInterceptor.get
The basic idea is to wrap calls to Trakt.TV's JSONP api through http://json2jsonp.com/ and have them returned transparently to get around cross site scripting restrictions. This would not only be very useful for my own project, but for a lot of other people daeling with the same issues too (therefore i'll release the module after it's done, but I want to do it properly)
The basics should be simple:
Hook the $http.get request at the right level
Overwrite the original request made
Cancel an optional other request already set up
Hook it through $http.jsonp(http://json2jsonp.com/)
Return the original promise's success/fail when done
Questions:
Has anyone built anything like this yet? (Github searches revealed nothing)
Would you suggest using the HTTPBackend or the HTTPInterceptor?
why can't you just use the jsonp helper function?
httpBakend is a mockup service to fake a backend server is not used on live code. http interceptors would do what you want you just need to attach the callback function name to your request if the url contains what ever name you want to filter and then in the response interceptor you have to pass response to the callback function so the json to be evaluated. be aware that interceptors will inspect every request makde by angular which is not very eficien, unless you are only doing calls to the tv service.
like i said before a better approach is to use $http.jsonp function
https://docs.angularjs.org/api/ng/service/$http#jsonp
a word about interceptors they need to be defined as services and then be passed to HttpProvider during your apps configuration.
I'm new to AngularJS and am trying to build myself a simple little app. I have JSON data for the app being fetched with $resource, and this data should be the same across multiple views/routes. However, when I go to a new route, the JSON data (stored as $scope.data) is no longer available to the new view. What can I do to pass this data to the new view and not require another fetch? (The tutorial phone-catalog app re-fetches this data every time from what I can tell.)
From what I understand, $rootScope can do this but it seems to be generally frowned upon. I apologize if this doesn't make much sense; I'm very much diving in the deep end here.
Use a service to store the data. Inject that service into each controller that needs access to this data. Each time a controller is created and executes (because you switch to another view/route), it can ask the service for the data. If the service doesn't yet have the data, it can make a request to the server and return a promise to the controller (see below for how to do that). If the service has the data, it can return it to the controller immediately.
See also Processing $http response in service
Note that services are singletons, unlike controllers.
Another variation: when the service is created, it can go fetch the data itself, and then store it for later use. Controllers can than $watch properties or functions on the service. For an example of this approach see How do I store a current user context in Angular?
I am trying to build my application's admin UI using sling's userManager REST interface, but I would like to customize the json rendering. For example, I would like the response of "Get group" to include the members only if the requestor is a member.
I started by adding libs/sling/group/json.esp but I don't understand how I can get hold of the default response and customize it. Even if I had to query and form the json from scratch, where can I find information about APIs available to get this data from JCR/Sling?
I found that I could use ResourceTraversor to dump the resource object in json form but using new Packages.org.apache.sling.servlets.get.impl.helpers.ResourceTraversor(-1, 10000, resource, true) in the esp throws up an error
There are a few things to note here.
First, you should avoid putting your code under the libs directory. Your app code should live under the apps directory. When attempting to resolve a servlet for a URI, Sling will check apps before it checks libs so if you need to completely override functionality delivered with Sling, you would place your code in apps.
Second, what is (probably, depending on how you have things setup) happening when you request http://localhost:8080/system/userManager/group/administrators.tidy.1.json is the request is being handled by Sling's default GET servlet, because it finds no other script or servlet which is applicable. For research purposes it might be worth looking at the code for the default get servlet, org.apache.sling.servlets.get.impl.DefaultGetServlet, to see what it's using to render JSON. If you need to handle the rendering of a user group in a manner different than what the default GET servlet is doing, then you would need to create a servlet which is listening for requests for resources of type sling/group. It would probably be ideal to create a servlet for this purpose and register it with OSGI. http://sling.apache.org/site/servlets.html provides the various properties you would need to set to ensure the servlet resolver finds your servlet. Your servlet then would handle the request and as such would have direct and easy access to the requested resource.
Third, the particular need you specified is that you do not want the group members to render unless the requesting user is a member of the group requested. This is more of an access control issue than a rendering issue. Sling and Jackrabbit, out of the box, make as few assumptions as possible concerning how you might want your application to be setup. That being the case, you need to establish the access controls that are applicable for your particular use case. The wiki post on Access Control in the Jackrabbit wiki ( http://wiki.apache.org/jackrabbit/AccessControl ) goes into this to an extent.
Using directions from Paul Michelotti's answer, I researched further and found a suitable solution to my problem.
Sling accepts request filters (javax.servlet.Filter) through SCR annotations like the one below
#SlingFilter(scope = SlingFilterScope.REQUEST, order = Integer.MIN_VALUE)
Every request is passed down to the filter before it is processed by the servlet. Using the resourceType, I was able to distinguish requests to group.1.json and group/mygroup.1.json. Since the filter also has access to the current user, I was able to decide to deny the request if it did not abide by my security model and return a 404 status code.
Please refer to this page for details on filters. You can also check out the sample project urlfilter for directions on usage.
