c# 微信公众号开发之自定义菜单栏

在微信公众号开启了第三方服务器之后，很多在微信平台上的配置都需要开发者通过微信提供的API，POST请求，将JSON字符串按格式，告知微信服务器

在这里介绍微信公众号的自定义菜单栏开发

先恭迎我们的TX文档 微信公众号——自定义菜单栏

官方文档里说明了一些需要注意的事项

在这里 我只使用了几个我业务中用到的类型 哈哈哈 本来在考虑要不要加在后台上，后来想想反正他们有事都找自己，直接写了一个get接口 要删要改，调接口

建立了一个菜单栏类

public class MenuModel{public MenuModel(string name = "", string type = "", string url = "", string key = "", string pagepath = "", string appid = ""){Sub_Button = new List<MenuModel>();if (name != ""){Name = name;}if (type != ""){Type = type;}if (url != ""){Url = url;}if (key != ""){Key = key;}if (pagepath != ""){Pagepath = pagepath;}if (appid != ""){Appid = appid;}}public List<MenuModel> Sub_Button { get; set; }/// <summary>/// 名字/// </summary>public string Name { get; set; }/// <summary>/// 类型/// </summary>public string Type { get; set; }/// <summary>/// 地址/// </summary>public string Url { get; set; }/// <summary>/// 菜单KEY值，用于消息接口推送/// </summary>public string Key { get; set; }/// <summary>/// 小程序页面地址/// </summary>public string Pagepath { get; set; }/// <summary>/// 小程序appid/// </summary>public string Appid { get; set; }//通过递归格式化所需json字符串public string ToJson(List<MenuModel> modelList){string result = "";foreach (var a in modelList){if (!a.Sub_Button.Any()){result += "{\"type\":\"" + a.Type + "\",\"name\":\"" + a.Name + "\",";if (a.Url != null){result += "\"url\":\"" + a.Url + "\",";}if (a.Key != null){result += "\"key\":\"" + a.Key + "\",";}if (a.Appid != null){result += "\"appid\":\"" + a.Appid + "\",";}if (a.Pagepath != null){result += "\"pagepath\":\"" + a.Pagepath + "\",";}string lastStr = result.Substring(result.Length - 1, 1);if (lastStr == ","){result = result.Substring(0, result.Length - 1);}result += "},";}else{result += "{\"name\":\"" + a.Name + "\",\"sub_button\":[";result += a.ToJson(a.Sub_Button);result += "},";}if (modelList.Count - 1 == modelList.IndexOf(a)){string lastStr = result.Substring(result.Length - 1, 1);if (lastStr == ","){result = result.Substring(0, result.Length - 1);}result += "]";}}return result;}}
