Important for Api Creation

Links: Good 

using Umbraco.Web.Mvc; // Allows to use – [PluginController(“AwesomeProducts”)]

using System.Web.Http;

[HttpGet]
public IEnumerable<string> Posts()
{  return new[] { "Post 1","Post 2","Post 3" };  }

Good one todo:

using System;
using System.Collections.Generic;
using Umbraco.Web.Mvc;
using System.Web.Http;
using Umbraco.Web.WebApi;

namespace Prodo.HousingSolutions.Web.Controllers.Api.Test
{
// Umbraco/AwesomeProducts/PostsApi/Test
[PluginController("AwesomeProducts")]
public class PostsApiController : UmbracoApiController
{
// BASIC API Creation

// post default
// domain/Umbraco/AwesomeProducts/PostsApi/IsUp
public bool IsUp()
{
return true;
}

// domain/Umbraco/AwesomeProducts/PostsApi/Posts
[HttpGet]
public IEnumerable<string> Posts()
{
return new[]
{
"Post 1","Post 2","Post 3"
};
}

// domain/Umbraco/AwesomeProducts/PostsApi/GetRandomNumbers
[HttpGet]
public IEnumerable<int> GetRandomNumbers(int? id)
{
List<int> numbers = new List<int>();
for (int i = 0; i < 10; i++)
{
int num = GetRandomNumber();
numbers.Add(num);

//double rDouble = r.NextDouble() * range;
}
return numbers; 
// return Enumerable.Repeat(new Random().Next(0, 10), 10);
}
private int GetRandomNumber()
{
Random random = new Random();
return random.Next(0, 100);
// OR
// for doubles
//int range = 100;
}

// is post request domain/api/getinsult/
[Route("api/getinsult")]
public string Insult()
{
return GetInsults();
}

private string GetInsults()
{
var insults = new[]

}

Structure should look like:

The – .csproj File must always be updated:

<ItemGroup>
<Compile Include=”Controllers\Api\ImportMembers\ImportMembersController.cs” />
<Compile Include=”Controllers\Api\SendInvite\SendInviteController.cs” />
</ItemGroup>
