1. Introduction to WeChat store shelves
In the background of the WeChat official account, shelf information can be maintained, and the interface is as follows. The concept of a shelf is to display products in categories to customers. A shelf is similar to a well-layed showcase. We can define different shelves and then publish different URLs for experience.
In addition, we generally create shelves based on the shelf template library. The shelf template allows us to quickly build a shelf and provides a visual reference interface. The shelf template interface is shown below.
For the development of WeChat stores using APIs, the shelf management operation interface of WeChat stores, It is similar to a regular module and has the following functional operations.
Although it looks similar to the previous object model, the shelf information is very complex, so if you need to restore it to an entity object based on Json data, you need to repeat it. Consider it carefully, otherwise it is easy to model errors.
Corresponds to the shelf template of the WeChat store management interface. The object information of the shelf includes 5 different control models, and some of them can be used in combination.
The model display of several shelves is shown below.

#endregion有了这些接口的定义，我们就需要实现对应的接口，从而实现我们向微信API的封装处理了。
微信小店的货架管理实现内容如下所示（部分内容，增删改）。

public AddShelfResult AddShelf(string accessToken, string shelfBanner, string shelfName, List<ShelfControlBase> controls)
{
var url = string.Format("https://api.weixin.qq.com/merchant/shelf/add?access_token={0}", accessToken);
var data = new
{
shelf_data = new
{
module_infos = controls
},
shelf_banner = shelfBanner,
shelf_name = shelfName
};
string postData = data.ToJson();
return JsonHelper<AddShelfResult>.ConvertJson(url, postData);
}

{

var data = new
{
shelf_id = shelfId
};
string postData = data.ToJson();
return Helper.GetExecuteResult(url, postData);
}

{
var url = string.Format("https://api.weixin.qq.com/merchant/shelf/mod?access_token={0}", accessToken);
var data = new
{
shelf_id = shelfId,
shelf_data = new
{

},

};
string postData = data.ToJson();
return Helper.GetExecuteResult(url, postData);
}由于货架管理的对象和接口定义比较复杂一些，一定需要进行反复的测试才能正式使用，如果不注意有可能你定义的实体类，获取不到某个字段信息。
我为了方便，创建了一个Winform项目，分别对各个接口进行测试。
对于货架管理内容的接口测试，测试代码如下所示。
private void btnShelf_Click(object sender, EventArgs e)
{
IMerchantApi api = new MerchantApi();
List<ShelfJson> list = api.GetAllShelf(token);
Console.WriteLine(list.ToJson());
foreach(ShelfJson json in list)
{
Console.WriteLine("货架信息：");
ShelfJson getJson = api.GetShelfById(token, json.shelf_id.Value);
Console.WriteLine(getJson.ToJson());
}
string shelf_banner = "http://mmbiz.qpic.cn/mmbiz/mLqH9gr11Gyb2sgiaelcsxYtQENGePp0RgeNlAQicfZQokjbJMUq4h8MHtjpekJNEWKuMN3gdRz5RxfkYb7NlIrw/0";
string shelf_name = "测试货架";
ShelfControl1 c11 = new ShelfControl1(6, 202797386);
ShelfControl1 c12 = new ShelfControl1(4, 202797397);
List<ShelfControlBase> controlList = new List<ShelfControlBase>(){c11, c12};
AddShelfResult result = api.AddShelf(token, shelf_banner, shelf_name, controlList);
if (result != null && result.shelf_id > 0)
{
Console.WriteLine("增加的货架信息：");
ShelfJson getJson = api.GetShelfById(token, result.shelf_id);
Console.WriteLine(getJson.ToJson());
shelf_name = "测试货架-修改";
controlList = new List<ShelfControlBase>(){c11};
CommonResult updateReuslt = api.UpdateShelf(token, result.shelf_id, shelf_banner, shelf_name, controlList);
Console.WriteLine("修改货架操作：{0}", updateReuslt.Success ? "成功" : "失败");
CommonResult deleteResult = api.DeleteShelf(token, result.shelf_id);
Console.WriteLine("删除货架操作：{0}", deleteResult.Success ? "成功" : "失败");
}
}
