(1) PLease upload your client side code to call talents API

(2) AWS url for web API if you have PUBLISHED your web api to AWS
    or url to S3 image

(3) Sequence diagram for calling Stripe API 
    or calling global weather web service

Some Screenshots for API annotations [Task 3]

Trying to POST object that is not compliant with annotated fields.

Attempting to POST object with fields that are not within pre-definied model.

Some screenshots regarding HTTPS authentication [Task 5]

When requesting with http://, it gets redirected to HTTPS. Below shows that an SSL protocol is needed to go through

Using Postman, there is no response when using http

Database Driven Approach

public class TalentController : ApiController
{
CSC_DatabaseEntitiesv1 db = new CSC_DatabaseEntitiesv1();
///

/// Get all talents objects from database
///

///
[RequireHttps]
[HttpGet]
[EnableCors(origins: "", headers: "", methods: "*")]
[Route("api/talents")]
public IEnumerable GetAllTalents()
{
List talents = db.Talents.ToList();
System.Threading.Thread.Sleep(1500);
return talents;
}

    /// <summary>
    /// Get one talent object from database by id
    /// </summary>
    /// <param name="id">The id of the talent object</param>
    /// <returns></returns>
    [Route("api/talents/{id:int}")]
    public Talent GetTalent(int id)
    {
        Talent item = db.Talents.SingleOrDefault(x => x.Id == id);
        if (item == null)
        {
            throw new HttpResponseException(HttpStatusCode.NotFound);
        }
        return item;
    }

Adding a Database Model

Reference

https://www.youtube.com/watch?v=UrHKfCCncHQ (Start from 2:03)

1. AJAX Timeout Retry

$.ajax({ type: 'GET', url: url, async: false, contentType: "application/json", jsonpCallback: callback, dataType: 'jsonp', tryCount: 0, retryLimit: 3, success: function (json) { console.dir('success'); }, error: function (xhr, textStatus, errorThrown ) { if (textStatus == 'timeout') { this.tryCount++; if (this.tryCount <= this.retryLimit) { sleep(1000); $.ajax(this); return; } return; } console.log(e.message); } });

2. Entity Framework (DotNet Core)

2.1 Startup - Specify services used
public void ConfigureServices(IServiceCollection services) { services.AddDbContext<TalentDbContext>( options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"))); services.AddScoped<ITalentRepository, SqlTalentRepository>(); services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1); }

2.2 TalentDbContext - Create DB Context

`
public class TalentDbContext : DbContext
{
public TalentDbContext(DbContextOptions options) : base(options) {}

    public DbSet<Talent> Talents { get; set; }
}

`

2.3 SqlTalentRepository - DB CRUD operations

`
public class SqlTalentRepository : ITalentRepository
{
private TalentDbContext _context;

    public SqlTalentRepository(TalentDbContext context)
    {
        _context = context;
    }

    public void Post(Talent inputTalent)
    {
        _context.Add(inputTalent);
        _context.SaveChanges();
    }

    public IEnumerable<Talent> GetAll() => _context.Talents;

    public Talent Get(int inputId) => _context.Talents.FirstOrDefault(t => t.Id == inputId);

    public void Put(int inputId, Talent inputTalent)
    {
        Talent talent = _context.Talents.FirstOrDefault(x => x.Id == inputId);
        if (talent != null)
        {
            _context.Talents.Remove(talent);
            _context.Talents.Add(inputTalent);
        }
        _context.SaveChanges();
    }
    public void Delete(int inputId)
    {
        Talent talent = _context.Talents.FirstOrDefault(x => x.Id == inputId);
        _context.Talents.Remove(talent);
        _context.SaveChanges();
    }
}

3. AJAX Loading

$(document).ajaxStart(function () { $("#loading").show(); }).ajaxStop(function () { $("#loading").hide(); });
