微信公众号自定义菜单创建方法

本人也是刚接触微信开发不久，希望能给小白一些帮助，下面直接看代码：

项目结构图：

前台页面效果：

一、前台页面：Index.cshtml

@{
ViewBag.Title = "微信公众号自定义菜单";
}
<script type="text/javascript">
function Post() {
document.getElementById("msg").innerHTML = "提交数据中...";
var url = "@Url.Action("CreateMenu","Menu")";
var postData = document.getElementById("postData").value;
var accessToken = document.getElementById("accessToken").value;
var par = {};
par.data = postData;
par.accessToken = accessToken;
$.ajax({
url: url,
type: 'post',
data:par,
success: function (msg) {
var result = JSON.parse(msg);
if (result.errcode==0) {
document.getElementById("msg").innerHTML = "自定义菜单成功！" + "[状态码：" + result.errcode + "消息：" + result.errmsg + "]";
return;
}
document.getElementById("msg").innerHTML = "自定义菜单失败！" + "[状态码：" + result.errcode + "消息：" + result.errmsg + "]";
}
})
}
function GetAccessToken() {
document.getElementById("msg1").innerHTML = "获取中...";
var appID = document.getElementById("appID").value;
var appSecret = document.getElementById("appSecret").value;
var url = "@Url.Action("GetAccessToken","Menu")";
var par = {};
par.appID = appID;
par.appSecret = appSecret;
$.ajax({
url: url,
type: 'get',
data: par,
success: function (msg) {
var result = JSON.parse(msg);//反序列号
document.getElementById("accessToken").value = result.access_token;
if (result.expires_in==7200) {
document.getElementById("msg1").innerHTML = "成功获取！";
return;
}
document.getElementById("msg1").innerHTML = "成功获取！";
}
})
}
</script>
<span>AppID(应用ID)</span><br />
<input type="text" name="name" value="wx01bf9adca00b21b1"style="1000px;" id="appID" /><br />
<br />
<span>AppSecret(应用密钥)</span><br />
<input type="text" name="name" value="1a1841aba9cc53662fa706456f224812"style="1000px;" id="appSecret" /><br />
<br />
<input type="button" value="GetAccessToken" onclick="GetAccessToken();" />
<span id="msg1"></span>
<br />
<br />
<hr />
<br />
<span>AccessToken</span><br />
<input type="text" name="name" value=""style="1000px;" id="accessToken"/><br />
<br />
<span>JSON</span><br />
<textarea id="postData" style="1000px;height:500px;"></textarea><br />
<input type="button" value="Post" onclick="Post();" />
<span id="msg"></span>

二、页面后台：MenuControllers

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using WechatPostMenu.Helper;

namespace WechatPostMenu.Controllers
{
public class MenuController : Controller
{
//
// GET: /Menu/

public ActionResult Index()
{
return View();
}
public ActionResult CreateMenu()
{
string data = Request.Form["data"];
string accessToken = Request.Form["accessToken"];
var json = HttpHelper.Post("https://api.weixin.qq.com/cgi-bin/menu/create?access_token=" + accessToken, data);
return Json(json);
}

public string GetAccessToken()
{
string appID = Request.QueryString["appID"];
string appSecret = Request.QueryString["appSecret"];
string url = string.Format("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={0}&secret={1}", appID, appSecret);
return HttpHelper.Get(url);
}

}
}

三、HttpHelper.cs类

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Security;
using System.Text;
using System.Web;

namespace WechatPostMenu.Helper
{
public class HttpHelper
{
public static string Post(string url, string paramData)
{
return Post(url, paramData, Encoding.UTF8);
}

public static string Post(string url, string paramData, Encoding encoding)
{
string result;

if (url.ToLower().IndexOf("https", System.StringComparison.Ordinal) > -1)
{
ServicePointManager.ServerCertificateValidationCallback =
new RemoteCertificateValidationCallback((sender, certificate, chain, errors) => { return true; });
}

try
{
var wc = new WebClient();
if (string.IsNullOrEmpty(wc.Headers["Content-Type"]))
wc.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
wc.Encoding = encoding;

result = wc.UploadString(url, "POST", paramData);
}
catch (Exception e)
{
throw;
}

return result;
}

public static string Get(string url)
{
return Get(url, Encoding.UTF8);
}

public static string Get(string url, Encoding encoding)
{
try
{
var wc = new WebClient { Encoding = encoding };
var readStream = wc.OpenRead(url);
using (var sr = new StreamReader(readStream, encoding))
{
var result = sr.ReadToEnd();
return result;
}
}
catch (Exception e)
{
throw e;
}
}
}
}
