asp.net 之微信自定义菜单创建
前段时间由于公司需要，申请了大批量的微信公众账号，并要求每个公众账号都需要创建自定义菜单，由于数量相当庞大，单个创建简直是个巨大的工作量，于是我开动脑筋，搞了一个自义定菜单管理后台，实现一键添加、删除自定义菜单：
- 管理后台是基于asp.net+MVC+dwz来写，至于什么是dwz自己百度，很简单也很实用的国产开源框架
-公众账号列表页面：
<div class="pageContent">
<div class="panelBar">
<ul class="toolBar">
<li><a class="icon" href="#" onclick="GetID()"><span>创建菜单</span></a></li>
<li><a class="delete" href="@Url.Content("~/WeiXin/DelMenu")" target="selectedTodo" title="确定删除该账号的自定义菜单吗？">
<span>删除菜单</span></a></li>
</ul>
</div>
<table class="table" width="100%" layouth="135">
<thead>

if (dt != null)
{
foreach (DataRow Dr in dt.Rows)
{
<tr target="ID" rel="@Dr["ID"].ToString()">

{
<input type="checkbox" name="ids" value="@Dr["ID"]"/>

</div>-公众号列表为了展示所有需要创建自定义菜单的公众账号，每条数据都加了复选框，允许多个账号同时创建菜单
创建菜单按钮事件控制器：
public ActionResult CreateMenu(string s1 = "")
{
DWZJson djson = null;
if (string.IsNullOrWhiteSpace(s1))
{
djson = new DWZJson() { message = "请选择要创建菜单的公众号", statusCode = "300" };
return Content(djson.ToJsonString());
}
//string[] ids = s1.Split(new char[1] { ',' }, StringSplitOptions.RemoveEmptyEntries);
//获取选中的公众账号名称
DataTable dt_accout = DALWeiXin.GetAccountList(s1);
StringBuilder sb = new StringBuilder();
if (dt_accout != null && dt_accout.Rows.Count > 0)
{
for (int i = 0; i < dt_accout.Rows.Count; i++)
{
sb.AppendFormat("<li class='{0}' style=\"display: inline; margin-right: 10px;\"><strong>☑ {1}</strong></li>", dt_accout.Rows[i]["ID"], HttpUtility.HtmlDecode(Convert.ToString(dt_accout.Rows[i]["AccountName"])));
}
}
ViewData["AccountList"] = sb.ToString();
//所有菜单列表
DataTable dt = DALWeiXin.getMenuList();
ViewBag.Table = dt;
ViewBag.accountID = s1;//对应公众账号id
return View();
}选择之后弹出菜单选择窗口，菜单以树形结构分两级展示，根据直观
弹窗页面：
@using System.Data;
@{
ViewBag.Title = "CreateMenu";
DataTable dt = ViewBag.Table;//菜单集合
}

return access_token;
}-至于后台取数据的方法就不贴了，不同程序不同用法，以上有些代码可以删除，比喻修改状态云云，就不多说了。以上有不到位的欢迎指正。
