Coupon Service Interface and Coupon Service Implementation - bondaigames/ASP.NET-Core-Documentation GitHub Wiki

• Create CouponDto.cs in Models/Dto folder

using Utility;
using System.Text.Json.Serialization;

namespace Web.Admin.Models.Dto
{
    public class CouponDto
    {
        [JsonPropertyName(PN.CouponId)]
        public int CouponId { get; set; }
        [JsonPropertyName(PN.CouponCode)]
        public string? CouponCode { get; set; }
        [JsonPropertyName(PN.DiscountAmount)]
        public double DiscountAmount { get; set; }
        [JsonPropertyName(PN.MinAmount)]
        public int MinAmount { get; set; }
    }
}

• Create Interface ICouponService.cs in Service\IService folder

using Web.Admin.Models.Dto;

namespace Web.Admin.Service.IService
{
    public interface ICouponService
    {
        Task<ResponseDto?> GetCouponAsync(string couponCode);
        Task<ResponseDto?> GetAllCouponsAsync();
        Task<ResponseDto?> GetCouponByIdAsync(int id);
        Task<ResponseDto?> CreateCouponsAsync(CouponDto couponDto);
        Task<ResponseDto?> UpdateCouponsAsync(CouponDto couponDto);
        Task<ResponseDto?> DeleteCouponsAsync(int id);
    }
}

• Go to SD.cs and add CouponApiBase Url

public static string CouponAPIBase { get; set; }

• Define url in appsettings.json

"ServicesUrls": {
  "CouponAPI": "https://localhost:7001",
}

• Create CouponService.cs in Service folder

using Web.Admin.Models.Dto;
using Web.Admin.Service.IService;
using Web.Admin.Utility;

namespace Web.Admin.Service
{
    public class CouponService : ICouponService
    {
        private readonly IBaseService _baseService;

        public CouponService(IBaseService baseService)
        {
            _baseService = baseService;
        }

        public async Task<ResponseDto?> CreateCouponsAsync(CouponDto couponDto)
        {
            return await _baseService.SendAsync(new RequestDto()
            {
                ApiType = SD.ApiType.POST,
                Data = couponDto,
                Url = SD.CouponAPIBase + "/api/coupon"
            });
        }

        public async Task<ResponseDto?> DeleteCouponsAsync(int id)
        {
            return await _baseService.SendAsync(new RequestDto()
            {
                ApiType = SD.ApiType.DELETE,
                Url = SD.CouponAPIBase + "/api/coupon/" + id
            });
        }

        public async Task<ResponseDto?> GetAllCouponsAsync()
        {
            return await _baseService.SendAsync(new RequestDto()
            {
                ApiType = SD.ApiType.GET,
                Url = SD.CouponAPIBase + "/api/coupon"
            });
        }

        public async Task<ResponseDto?> GetCouponAsync(string couponCode)
        {
            return await _baseService.SendAsync(new RequestDto()
            {
                ApiType = SD.ApiType.GET,
                Url = SD.CouponAPIBase + "/api/coupon/GetByCode/" + couponCode
            });
        }

        public async Task<ResponseDto?> GetCouponByIdAsync(int id)
        {
            return await _baseService.SendAsync(new RequestDto()
            {
                ApiType = SD.ApiType.GET,
                Url = SD.CouponAPIBase + "/api/coupon/" + id
            });
        }

        public async Task<ResponseDto?> UpdateCouponsAsync(CouponDto couponDto)
        {
            return await _baseService.SendAsync(new RequestDto()
            {
                ApiType = SD.ApiType.PUT,
                Data = couponDto,
                Url = SD.CouponAPIBase + "/api/coupon"
            });
        }
    }
}
