Aspnet core request count logging - asp.net-core

I have 2 controller and each controller has 2 endpoints. For example:
GET /categories
GET /category/{id}
Basically I want to know how many one or another endpoint is being used.
So the final result I want to count the calls. For example one endpoint was used X amount of times and another used Y amount of times. And I want to get this string: $"{id} is the most popular category"
How to do it? I need a statistic for my web api

getAllContentServices returns Huge Data

I am using Yodlee “getAllContentServices” API to get all content services. But service returns a
huge amount of data (More Than 26 MBs) and returns more than 12k records, which is very difficult
to handle in a single service call, Is it any other way exist to access this service page wise.
Thanks
There are two options to do this -
call getAllContentServices and pass "notrim=false" and then for each contentService ID you can call - getContentServiceInfo1 with desired reqSpecifier to get the information.
OR
Use getContentServicesByContainerType2 and get the list of content services based on the container type.

User's history and pagination with Deezer APIs

if I try to get the streaming history of a user, e.g.
http://api.deezer.com/2.0/user/.../history?access_token=...
I get the first result page but I don't see any method/parameter (like next, page, ...) to see the rest of the results.
How can I get the following result pages?
Thanks.
There are two parameters available to control the paging of data:
limit: the number of individual track objects that are returned in the request.
index: the individual track objects at the specified index that is the first result of the request to be returned.
Please, compare these two requests to get a better understanding of the paging system:
http://api.deezer.com/user/YOUR_USER_ID/history?access_token=YOUR_ACCESS_TOKEN&index=0&limit=10 will return the 10 latest tracks you listened to.
http://api.deezer.com/user/YOUR_USER_ID/history?access_token=YOUR_ACCESS_TOKEN&index=4&limit=5 will return the 5 tracks before the 5 latest tracks you listened to.
For your information, you cannot return more than 50 individual objects per page.

Include count of linked records in OData result

I've got a table "Events" with a linked table "Registrations", and I want to create an OData service that returns records from the Events table, plus the number of registrations for each event. The data will be consumed client-side in JavaScript, so I want to keep the size of the returned data down and not include all linked registration records completely.
For example:
ID Title Date Regs
1 Breakfast 01.01.01 12:00 4
2 Party 01.01.01 20:00 20
I'm building the service with ASP.NET MVC4. The tables are in an MSSQL database. I am really just getting started with OData and LINQ.
I tried using the WebAPI OData system first (using classes of EntitySetController) but was getting cryptic server errors as soon as I included the Registrations table in the entity set. ("The complex type 'Models.Registration' refers to the entity type 'Models.Event' through the property 'Event'.")
I had more success building a WCF OData system, and can request event information and information on related registrations.
However, I have no clue how to include the aggregate count information in the event result set. Do I need to create a custom entity set that will be the source for the OData service? I probably included too litte information here for finding a solution, but I don't really know where to look. Can somebody help me?
If you're willing to make an extra request per Event, you could query http://.../YourService.svc/Events(<key>)/Registrations/$count (or http://.../YourService.svc/Events(<key>)/$links/Registrations?$inlinecount=allpages if you're also using the links to the Registration entities).
Examples of both of these approaches on a public service:
http://services.odata.org/V3/OData/OData.svc/Suppliers(0)/Products/$count
http://services.odata.org/V3/OData/OData.svc/Suppliers(0)/$links/Products?$inlinecount=allpages&$format=json
I'm guessing that you'd prefer this information to come bundled together with the rest of the Events response though. It's not ideal, but you could issue a query along these lines:
http://services.odata.org/V3/OData/OData.svc/Suppliers?$format=json&$expand=Products&$select=Products/ID,*
I'm expanding Products (analogous to your Registrations) and selecting Products/ID in order to force the response to include an array that is the same size as the nested Products collection. I don't care about ID -- I just chose a piece of data that would be small. With this JSON response, your javascript client can get the length of the Products array and use that as the number of Products that are linked to the given Supplier.
(Note: to have your service support $select queries using WCF Data Services, you'll need to include this line when you initialize the service: config.DataServiceBehavior.AcceptProjectionRequests = true;)
Edit to add: The approach using $expand and $select won't be guaranteed to give you the correct count if your server does server-driving paging. In general, there isn't a simple single-response way to do what you're asking for in OData v3, but in OData v4, this will be possible with the new expand/select syntax.
i'm using oData v4 and i used this syntax :
var url = '.../odata/clients?$expand=Orders($count=true)';
// ...
a field called Orders#odata.count has been added to the response entity which contains the correct count.
and now to access the JSON property containing a dash you have to do it like this :
var ordersCount = response.value['Orders#odata.count'];
hope this helps.
Can you edit your Event model and add a RegistrationCount property? That'd be the simplest way I think
What I ended up doing was actually very simple; I created a View in SQL Server that returns the table including the registration counts. Never thought about using a view, since I've never used them before...
I used this to get the child count without returning the entities:
/Parents$expand=Children($count=true;$top=0)

Organising resource (URI) in REST API

Scenario 1
In my web application say for there is a screen for adding an employee to system. As soon as user tabs after entering name of the employee, it generates the employee code automatically (which is the next field) based on some logic and already present records in the database.
Now I want to expose rest API for this application so that third party devs can build on top of it. So, I will have a resource called as /Employee which will respond for GET, PUT and DELETE verbs. But when a client needs to autofill the code, which is a GET operation, it will be on what resource? Should I make a new resource /EmployeeCodeFor/{Name} or I should get it on /Employee/{Name}/GenerateCode? If I go with /Employee/{Name}/GenerateCode then what about my resource to GET, PUT and DELETE for Employee i.e. actually /Employee/{Id}?
Scenario 2
Here lets take the case of a stackoverflow post. So lets say the resource would be /Post/{Id}. In the same way as in the previous example it lists me possible duplicate question as soon as I tab out of the Title field.
Again on what URL I should get those possible duplicates?
I can't think of more scenarios just now. But many such kind of scenarios may come up in real life application development. How to implement them in RESTful way?
Update on scenario 1
Code and Id are two different fields. Id is primary key, code can be duplicate across departments just to illustrate. Also to generate a code, name should be provided first. So, if user types a name "FirstName LastName" then server might generate FL003 as code assuming that there are already two more employees with firstname starting from F and lastname starting from L in the said department. Department can be identified based on the logged in user.
One way to allow the server an opportunity to pre-fill a bunch of elements in a new resource is to do
POST /Employees
{with empty body}
=>
201 Created
Location: http://example.org/employee/3443
<Employee Id="3443">
<Code>E1001</Code>
<FirstName></FirstName>
<LastName></LastName>
</Employee>
This gives the server one chance to provide default values. If you are looking for a more interactive way for the server to provide feedback during the input, I have another approach but it will take quite a bit more explaining.
Scenario 1
Let say your employee code is a unique identifier. In this case, to get it, you would allow the user to complete any field for the new employee and then make a POST. The server would generate the code and respond to the POST with a link to /Employee/{generated_code} which is the record for your newly created employee.
A GET on /Employee would return a list of all employees. A GET on /Employee/{a_code} will give you the employee detail.
Scenario 2
You could have some kind of query on the /Post collection like /Post?title_like={question_title}. A GET /Post?title_like=REST How to would return you a list of all questions containing "REST How to".

How can I use expand() to include multiple levels of eager loaded properties for an entity with WCF Data Services for Silverlight?

I'm using Silverlight 4.0 (so I need to make the call async and can't use EF directly) with a WCF Data Service and EF 4 to model the database.I want to make one call and have several levels of properties populated.
Say I have the following setup (but this could go deeper):
Accounts
-- has zero or more Customers (and other properties)
-- Customer has zero or more Addresses (and other properties)
I want to bring back 1 payload where Accounts, Customers, and Addresses are all eager loading and included in that one payload.
I want to get : Accounts.Expand("Customers").Where(a => a.Id == 1); This returns the payload with the account and customer populated. How do I include the Addresses in the same call?
Just add Expand("Customers/Addresses"), you can add more of these, although there's a limit usually on the server. Something like 10 expanded entities should work, more might be problematic.
