後端的WebApi（Erp和Shipping兩個項目進行分佈式部署）

Shipping項目

1.Model（將新增的字段經過程序包管理器控制檯映射到數據庫）

using Lmt.Shared.Domains;
using Shipping.Shared;
using System.ComponentModel;
using System.Collections;
using System.Collections.Generic;

namespace Shipping.Domains.Models {
    public class SelectedShippingService :IModel{


        public long Id { get; protected set; }
        public long WarehouseId { get; protected set; }
        public long SsId { get; protected set; }
        public bool IsActive { get; set; }

        public Operator Operator { get; private set; }


        /// <summary>
        /// 物流屬性
        /// </summary>
        public string ShippingAttribute { get; set; }


        public LogisticsTypes LogisticsType { get; set; }

        /// <summary>
        /// 物流分類
        /// </summary>
        public enum LogisticsTypes
        {
            [Description("快遞")]
            Expressal = 1,
            [Description("掛號")]
            Register = 2,
            [Description("平郵")]
            SurfaceMail = 3,
            [Description("專線掛號")]
            SpecialRegister = 4,
            [Description("專線平郵")]
            SpecialSurfaceMail = 5,
            [Description("虛擬海外倉")]
            VirtualRsealocation = 6,
        }

        /// <summary>
        /// 預估運輸時間
        /// </summary>
        public int? StartDay { get; set; }
        public int? EndDay { get; set; }

        public static SelectedShippingService Create(long warehouseId,long ssId,long userId) {
            return new SelectedShippingService {
                SsId = ssId,
                WarehouseId = warehouseId,
                Operator = new Operator(UserOperator.Create(userId))
            };
        }
    }
}

View Code

2.Commands（調用Model類）

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Lmt.Shared.Domains;
using Shipping.Shared;
using static Shipping.Domains.Models.SelectedShippingService;

namespace Shipping.Domains.Commands
{
    public class UpdateShippingServiceAttributeCommand
    {
        public long SsId { get; set; }

        public LogisticsTypes LogisticsType { get; set; }

        public int? StartDay { get; set; }
        public int? EndDay { get; set; }

        public List<ShippingAttributeType> ShippingAttribute { get; set; }
    }
}

View Code

3.Services（EF鏈接數據庫進行增刪改查）

修改物流屬性的方法

 public async Task SetLogisticsAttribute(UpdateShippingServiceAttributeCommand command, long userId)
        {
            using (var db = Db.Shippings)
            {
                var selectedSSsId = db.SelectedShippingServices.FirstOrDefault(m => m.Id == command.SsId);
                if (selectedSSsId == null)
                {
                    throw new DomainException("未找到該數據的信息");
                }
                selectedSSsId.LogisticsType = command.LogisticsType;
                selectedSSsId.StartDay = command.StartDay;
                selectedSSsId.EndDay = command.EndDay;
                selectedSSsId.ShippingAttribute = string.Join(",", command.ShippingAttribute);
                selectedSSsId.Operator.Update(userId);
                await db.SaveChangesAsync().ConfigureAwait(false);
            }
        }

View Code

查詢修改後的方法

 public async Task<UpdateShippingServiceAttributeCommand> QueryLogisticsAttribute(long ssid,long userId)
        {
            using (var db = Db.Shippings)
            {
                var selectedSSsId = db.SelectedShippingServices.FirstOrDefault(m => m.Id == ssid);
                if (selectedSSsId == null)
                {
                    throw new DomainException("未找到該數據的信息");
                }
                List<ShippingAttributeType> type = new List<ShippingAttributeType>();
                if (!selectedSSsId.ShippingAttribute.IsNullOrEmpty())
                {
                    var attr = selectedSSsId.ShippingAttribute.Split(',');
                    foreach (var item in attr)
                    {
                        var enums = (ShippingAttributeType)Enum.Parse(typeof(ShippingAttributeType), item);
                        type.Add(enums);
                    }
                }
                
                var Query = new UpdateShippingServiceAttributeCommand() {
                    SsId=ssid,
                    ShippingAttribute = type, 
                    LogisticsType = selectedSSsId.LogisticsType,
                    StartDay = selectedSSsId.StartDay,
                    EndDay = selectedSSsId.EndDay, };
                return Query;


            }
        }

View Code

4.WebApi（調用Services中的類，定義路由規則給前端Angular.js頁面調用）

修改->Post

 [Route("SetLogistics"), HttpPost]
        [ResponseType(typeof(bool))]
        public async Task<HttpResponseMessage> SetLogisticsAttribute(UpdateShippingServiceAttributeCommand command)
        {
            var shippingMethodService = new ShippingMethodService();
            await shippingMethodService.SetLogisticsAttribute(command, CurrentUser.UserId).ConfigureAwait(false);
            return OkResult(true);
        }

View Code

查詢->Get

 [Route("QueryLogistics/{ssId:long}"),HttpGet]
        [ResponseType(typeof(UpdateShippingServiceAttributeCommand))]
        public async Task<HttpResponseMessage> QueryLogisticsAttribute(long ssid)
        {
            var shippingMethodService = new ShippingMethodService();
            var attributeCommand = await shippingMethodService.QueryLogisticsAttribute(ssid, CurrentUser.UserId).ConfigureAwait(false);
            return OkResult(attributeCommand);
        }

View Code

 

Erp的項目

1.ShippingModel（和Model保持一致）

using Shipping.Shared;
using System;
using System.Collections.Generic;
using static Shipping.Domains.Models.SelectedShippingService;

namespace Erp.ApiClients.Shipping.RequestModel
{
    public class UpdateShippingServiceAttributeRequest
    {
        public long SsId { get; set; }

        public LogisticsTypes LogisticsType { get; set; }

        public int? StartDay { get; set; }
        public int? EndDay { get; set; }

        public List<ShippingAttributeType> ShippingAttribute { get; set; }
    }
}

View Code

2.調用Shipping項目的WebApi的路徑（兩邊的接口經過反序列化進行數據的傳遞）

調用修改的Post路徑

 public Task<WebApiResult<bool?>> SetLogisticsAttribute(UpdateShippingServiceAttributeCommand command, long userId)
        {
            var request = new UpdateShippingServiceAttributeRequest
            {
                LogisticsType = command.LogisticsType,
                ShippingAttribute = command.ShippingAttribute,
                StartDay = command.StartDay,
                EndDay = command.EndDay,
                SsId = command.SsId
            };
            return ApiClient
                .Auth(DmtApiAuth.User(userId))
                .Path("api/v1/shipping-service/SetLogistics")
                .PostJsonAsync<WebApiResult<bool?>>(request);
        }

View Code

調用查詢的Get路徑

 public Task<WebApiResult<UpdateShippingServiceAttributeRequest>> QueryLogisticsAttribute(long ssid, long userId)
        {
            return ApiClient
                .Auth(DmtApiAuth.User(userId))
                .Path($"api/v1/shipping-service/QueryLogistics/{ssid}")
                .GetAsync<WebApiResult<UpdateShippingServiceAttributeRequest>>();
        }

View Code

3.Services（EF鏈接數據庫進行增刪改查）

修改

 public async Task SetLogisticsAttribute(UpdateShippingServiceAttributeCommand command, long userId)
        {
            await CallShippingApi(c => c.SetLogisticsAttribute(command, userId)).ConfigureAwait(false);
        }

View Code

查詢

 public async Task<UpdateShippingServiceAttributeRequest> QueryLogisticsAttribute(long ssid,long userId)
        {
            return await CallShippingApi(c => c.QueryLogisticsAttribute(ssid,userId)).ConfigureAwait(false);
        }

View Code

4.WebApi（調用Services中的類，定義路由規則給前端Angular.js頁面調用）

定義路由規則的入口

 [RoutePrefix("api/v1/shipping/shipping-method")]
    public class ShippingServiceController : ErpApiController {
        private readonly ShippingMethodService _shippingMethodService;

        public ShippingServiceController() {
            _shippingMethodService = new ShippingMethodService();
        }

...

}

View Code

修改的WebApi

  [Route("setLogisticsAttribute"), HttpPost]
        [ResponseType(typeof(bool))]
        public async Task<HttpResponseMessage> SetLogisticsAttribute(UpdateShippingServiceAttributeCommand command)
        {
            var ssService = new ShippingMethodService();
            await ssService.SetLogisticsAttribute(command, User.UserId).ConfigureAwait(false);
            return OkResult(true);
        }

View Code

查詢的WebApi

[Route("queryLogisticsAttribute"), HttpPost]
        [ResponseType(typeof(UpdateShippingServiceAttributeCommand))]
        public async Task<HttpResponseMessage> QueryLogisticsAttribute(long ssid)
        {
            var ssService = new ShippingMethodService();
            var attributeCommand = await ssService.QueryLogisticsAttribute(ssid,User.UserId).ConfigureAwait(false);
            return OkResult(attributeCommand);
        }

View Code

 5.附加（在查詢中去重複數據，在ERP的主表新增SelectedShippingServicesId來關聯Shipping表中的主鍵ID）

在Model中新增字段

using System.Collections.Generic;
using Erp.Shared;

namespace Erp.ApiClients.Shipping.ResponseModel {
    public class ShippingServiceListModel {
        public long SsId { get; set; }
        public string SsCode { get; set; }
        public string SsName { get; set; }

        /// <summary>
        /// 物流別名
        /// </summary>
        public string ShippingServiceAlias { get; set; }

        public string SpCode { get; set; }
        public string SpName { get; set; }
        public long SpId { get; set; }

        public long? SelectedShippingServicesId { get; set; }

        public bool NeedAuthorize { get; set; }
        public bool? IsAuthorized { get; set; }

        public bool IsActive { get; set; }
        public bool IsCustom { get; set; }
        public string LogisticsProviderShippingMethod { get; set; }
        public bool IsSelected { get; set; }
        public bool HasTrackingNumber { get; set; }
        public string TrackingNumberApiName { get; set; }
        public TrackingNumberApiFetchType TrackingNumberApiFetchType { get; set; }

        public List<ShippingMethodCarrireCodeModel> CarrireCodes { get; set; }
    }
 
    public class ShippingMethodCarrireCodeModel {
        public ChannelType ChannelType { get; set; }
        public string CarrierCode { get; set; }
        public string CustomCarrierName { get; set; }
    }
}

 6.屬性的枚舉類

using System.Collections.Generic;
using System.ComponentModel;

namespace Shipping.Shared {

    public enum ShippingAttributeType {
        [Description("普貨")]
        Normal = 0,
