这篇文章给大家分享的是有关微信公众号开发中如何设置自定义菜单的内容。小编觉得挺实用的,因此分享给大家做个参考,一起跟随小编过来看看吧。
1、首先我们需要新建一个数据库表用于存放menu菜单项
可包含的字段有id、父类id、name、排序、是否显示、类型(view、click)、链接、adddate
注意后台存menu菜单数据时,parentId=-1为一级菜单,或parendId为一级菜单的id作为该一级菜单下的二级菜单
2、在设置菜单时需要向微信接口传menuJson字符串,所以要先拼接字符串,后台定义一个creatMenu()
public bool creatMenu()
{
string menuJson = "";
//这里默认parentId=-1为最外层菜单,isactive=1为显示,respOnseType=1为click类型
DataTable dtAMenu = Service.SelectDataTable("id, name, responseType, jsonStr,url", "WEIXINMENU", " parentId=-1 and isactive=1 order by sort");
if (dtAMenu.Rows.Count > 0)
{
menuJson = "{\"button\":[";
for (int i = 0; i < dtAMenu.Rows.Count; i++)
{
DataTable dtBMenu = Service.SelectDataTable("id, name, responseType, jsonStr,url", wx, " parentId=" + dtAMenu.Rows[i]["id"].ToString() + " and isactive=1 order by sort");
if (dtBMenu.Rows.Count > 0)
{
menuJson += "{\"name\":\"" + dtAMenu.Rows[i]["name"].ToString() + "\",\"sub_button\":[";
for (int j = 0; j < dtBMenu.Rows.Count; j++)
{
if (Convert.ToInt32(dtBMenu.Rows[j]["responseType"]) == 2)
{
menuJson += "{\"type\":\"view\",\"name\":\"" + dtBMenu.Rows[j]["name"].ToString() + "\",\"url\":\"" + dtBMenu.Rows[j]["jsonStr"].ToString() + "\"},";
}
else
{
menuJson += "{\"type\":\"click\",\"name\":\"" + dtBMenu.Rows[j]["name"].ToString() + "\",\"key\":\"eventKey_" + dtBMenu.Rows[j]["id"].ToString() + "\"},";
}
}
menuJson = menuJson.TrimEnd(&#39;,&#39;);
menuJson += "]},";
}
else
{
//if (Convert.ToInt32(dtAMenu.Rows[i]["responseType"]) == 2)
//{
menuJson += "{\"type\":\"view\",\"name\":\"" + dtAMenu.Rows[i]["name"].ToString() + "\",\"url\":\"" + dtAMenu.Rows[i]["jsonStr"].ToString() + "\"},";
//}
//else
//{
// menuJson += "{\"type\":\"click\",\"name\":\"" + dtAMenu.Rows[i]["name"].ToString() + "\",\"key\":\"eventKey_" + dtAMenu.Rows[i]["id"].ToString() + "\"},";
//}
}
dtBMenu.Dispose();
}
dtAMenu.Dispose();
menuJson = menuJson.TrimEnd(&#39;,&#39;);
menuJson += "]}";
menuJson = menuJson.Trim();
return requstZmToCreatMent(menuJson);
}
else
{
return false;
}
}
3、获取到menujson字符串后调用微信接口创建菜单,需先获取assess token,有关assess token获取可参考:获取AccessToken
///
/// 向微信服务器请求创建自定义菜单
///
///
///
///
private bool requstZmToCreatMent(string jsonStr)
{
try
{
var AccessToken = "";//accesstoken需例外获取,一般可开始时获取后存数据库,下次从数据库取,注意accesstoken有效期为7200秒
//声明一个HttpWebRequest请求
string interfaceUrl = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=" + AccessToken;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(interfaceUrl);
//设置连接超时时间
request.Timeout = 30000;
request.KeepAlive = true;
Encoding encodeType = Encoding.GetEncoding("UTF-8");
request.Headers.Set("Pragma", "no-cache");
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; Maxthon; .NET CLR 1.1.4322); Http STdns";
request.Accept = "image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*";
request.COOKIEContainer = new COOKIEContainer();
byte[] Bytes = encodeType.GetBytes(jsonStr);
request.ContentLength = Bytes.Length;
request.AllowAutoRedirect = true;
//发送数据
using (Stream writer = request.GetRequestStream())
{
writer.Write(Bytes, 0, Bytes.Length);
writer.Close();
}
StringBuilder strb = new StringBuilder();
//接收数据
using (Stream reader = request.GetResponse().GetResponseStream())
{
StreamReader sr = new StreamReader(reader, encodeType);
strb.Append(sr.ReadToEnd());
sr.Close();
reader.Close();
}
if ((strb.ToString().IndexOf("\"errcode\":42001") != -1) || (strb.ToString().IndexOf("\"errcode\":40001") != -1) || (strb.ToString().IndexOf("\"errcode\":40014") != -1) || (strb.ToString().IndexOf("\"errcode\":41001") != -1)) //access_token错误
{
// AccessToken = getAccessToken();
getzmAccessToken();
return requstZmToCreatMent(jsonStr);
}
else
{
if (strb.ToString() == "{\"errcode\":0,\"errmsg\":\"ok\"}")
{
return true;
}
else
{
return false;
}
}
}
catch (Exception exp)
{
return false;
}
}
