This article began to formally do the function, before I developed the reminder of puzzle puzzle, the function of reminding sellers that puzzle puzzle is too many and the number of puzzle puzzle is not enough.

This idea comes mainly from the complaints of friends. I think it should be the voice of most sellers.

After analysis, I got several api s. Don't ask me how I got them. This is not the content of this series.

Interface 1: http://apiv4.yangkeduo.com/mall/{0}/info?pdduid=0

Interface 2: http://apiv4.yangkeduo.com/v2/mall/{0}/goods? Page=1&size=500&sort_type=PRIORITY&pdduid=0 (pass in store number, you can get store information, and limit access to up to 500 items)

Interface 3: http://apiv2.yangkeduo.com/v2/goods/{0}/local_group

With these api s, the jigsaw reminder function is out of the question. Next, we will explain the implementation process.

 

Establishment of new projects

Build a PddTool project under the solution, aiming at putting together many related business logic in a special class library.

 

Right-click on the solution to select the "NuGet package for managing the solution", search for and install the following NuGet package, pay attention to the version number.

 

 

To create a directory, first create several directories, as shown in the following figure:

 

Create a new MallEntity class in the Response directory with the following code:

public class MallEntity
    {
        /// <summary>
        /// 
        /// </summary>
        public int mall_id { get; set; }

        public int goods_num { get; set; }
        /// <summary>
        /// The shop mainly manages fashion fashion women's clothes, quality women's clothes, quality assurance!

        public string mall_desc { get; set; }
        /// <summary>

        public string company_phone { get; set; }
        /// <summary>

        public string offline_note { get; set; }

        public int wms_id { get; set; }
        /// <summary>

        public List<string> mall_coupons { get; set; }
        /// <summary>
        /// 
        /// </summary>
        public int server_time { get; set; }
    }

 

 

This is the class generated by returning json data after requesting the api.

http://www.bejson.com/convert/json2csharp/(through this tool, you can transfer JSON to C entity class)

New ProductEntity class under the same directory, code as follows:

/// <summary>
    /// Assemble
    /// </summary>
    public class Group
    {
        /// <summary>
        /// Group number

    }

    public class ProductEntity
    {
        /// <summary>

        /// 
        /// </summary>
        public List<string> subject_list { get; set; }
    }

 

 

Create the KaiTuanEntity class under the same directory. The code is as follows:

public class Local_groupItem
    {
        /// <summary>
        /// Group order id
        /// </summary>
        public string group_order_id { get; set; }
        /// <summary>
        /// commodity id
        /// </summary>
        public string goods_id { get; set; }
        /// <summary>
        /// City name
        /// </summary>
        public string city_name { get; set; }
        /// <summary>
        /// Nickname?
        /// </summary>
        public string nickname { get; set; }
        /// <summary>
        /// Head portrait
        /// </summary>
        public string avatar { get; set; }
        /// <summary>
        /// 
        /// </summary>
        public string expire_time { get; set; }
        /// <summary>
        /// user id
        /// </summary>
        public string uid { get; set; }
    }

    public class KaiTuanEntity
    {
        /// <summary>
        /// Collage List in progress
        /// </summary>
        public List<Local_groupItem> local_group { get; set; }
        /// <summary>
        /// 
        /// </summary>
        public int server_time { get; set; }
        /// <summary>
        /// Number of group members in progress
        /// </summary>
        public int total { get; set; }
    }

 

 

Then in the Entities directory, create the KaiTuan class, code as follows:

public class KaiTuan
    {
        /// <summary>
        /// commodity id
        /// </summary>
        public int Id { get; set; }

        /// <summary>
        /// Nickname?
        /// </summary>
        public string NickName { get; set; }

        /// <summary>
        /// 
        /// </summary>
        public string SKU { get; set; }

        /// <summary>
        /// Order number
        /// </summary>
        public string OrderNum { get; set; }

        /// <summary>
        /// Remaining time
        /// </summary>
        public double TimeLeft { get; set; }

        /// <summary>
        /// Group number
        /// </summary>
        public string KaiTuanOrderNum { get; set; }
    }

 

 

Continue to create the KaiTuanProduct class under the Entities directory with the following code:

/// <summary>
    /// Group merchandise
    /// </summary>
   public  class KaiTuanProduct
    {
        /// <summary>
        /// commodity id
        /// </summary>
        public int GoodId { get; set; }
        /// <summary>
        /// Trade name
        /// </summary>
        public string Name { get; set; }

        /// <summary>
        /// Commodity pictures
        /// </summary>
        public string Img { get; set; }
        /// <summary>
        /// Number of persons opening
        /// </summary>
        public int KaiTuanCount { get; set; }
    }

 

 

Create the DateTimeHelper class under the class library. The code is as follows:

public class DateTimeHelper
    {
        /// <summary>
        /// afferent unix Timestamp, calculating the number of hours between the current time
        /// </summary>
        /// <param name="unixTimeStamp"></param>
        /// <returns></returns>
        public static double GetHours(long unixTimeStamp)
        {
            System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970, 1, 1)); // Local time zone
            DateTime dt = startTime.AddSeconds(unixTimeStamp);
            var a = dt - DateTime.Now;
            
            return Math.Round(a.TotalHours, 1);
        }
    }

 

 

The MallTool class is created under the class library and several methods are implemented. The code is as follows:

public class MallTool
    {
        /// <summary>
        /// By store id Access to store information
        /// </summary>
        /// <param name="mallId"></param>
        public static MallEntity GetInfo(string mallId)
        {
            string url = string.Format("http://apiv4.yangkeduo.com/mall/{0}/info?pdduid=0", mallId);
            var client = new RestClient(url);
            var request = new RestRequest(Method.GET);
            request.AddHeader("cache-control", "no-cache");
            request.AddHeader("referer", url);
            IRestResponse response = client.Execute(request);
            if (string.IsNullOrWhiteSpace(response.Content) || response.Content.Contains("mall not exists"))
            {
                throw new Exception("The shop number is wrong!");
            }
            var mall = JsonConvert.DeserializeObject<MallEntity>(response.Content);
            return mall;
        }

        /// <summary>

            request.AddHeader("referer", url);
            IRestResponse response = client.Execute(request);
            var product = JsonConvert.DeserializeObject<ProductEntity>(response.Content);

You can see that UserFriendlyException reports exceptions, which are ABP exception classes. Then the solution opens the NuGet package of the management solution and searches for "abp" installation.

Finally, the structure of the project is as follows. The reminder function is encapsulated.

 

 

Create unit tests

Create a new unit test project under the Solution Tests directory, as shown in the following figure:

 

Create a new MallTool_Test class to test several methods just encapsulated. The code is as follows:

[TestClass]
    public class MallTool_Test
    {
        public string mallId { get; set; } = "1277675";
        [TestMethod]
        public void TestGetInfo()
        {
            MallEntity result=MallTool.GetInfo(mallId);
            Console.WriteLine(result.mall_name);
        }
    }

 

 

The following figure shows the output of debugging:

 

The above code is passed into the store number to obtain the store information.

Where does the store number come from?

Through the above links, you can inquire about the information of more than one item. Then you can click on a random item and click "Shop in", as shown in the following figure:

 

When you come in, you can see the number of the store in the address bar, as shown in the following figure:

 

Several other methods are similar, so they are not explained one by one.
