本實(shí)例是為了實(shí)現(xiàn)在管理后臺(tái)實(shí)現(xiàn)微信菜單的添加刪除管理。

1、首先我們需要新建一個(gè)數(shù)據(jù)庫表用于存放menu菜單項(xiàng)

可包含的字段有id、父類id、name、排序、是否顯示、類型(view、click)、鏈接、adddate

注意后臺(tái)存menu菜單數(shù)據(jù)時(shí)，parentId=-1為一級(jí)菜單，或parendId為一級(jí)菜單的id作為該一級(jí)菜單下的二級(jí)菜單

2、在設(shè)置菜單時(shí)需要向微信接口傳menuJson字符串，所以要先拼接字符串，后臺(tái)定義一個(gè)creatMenu()

public bool creatMenu()

{

string menuJson = "";

//這里默認(rèn)parentId=-1為最外層菜單，isactive=1為顯示,responseType=1為click類型

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(',');

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(',');

menuJson += "]}";

menuJson = menuJson.Trim();

return requstZmToCreatMent(menuJson);

}

else

{

return false;

}

}

3、獲取到menujson字符串后調(diào)用微信接口創(chuàng)建菜單，需先獲取assess token,有關(guān)assess token獲取可參考：獲取AccessToken

///

/// 向微信服務(wù)器請(qǐng)求創(chuàng)建自定義菜單

///

///

///

///

private bool requstZmToCreatMent(string jsonStr)

{

try

{

var AccessToken = "";//accesstoken需例外獲取，一般可開始時(shí)獲取后存數(shù)據(jù)庫，下次從數(shù)據(jù)庫取，注意accesstoken有效期為7200秒

//聲明一個(gè)HttpWebRequest請(qǐng)求

string interfaceUrl = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=" + AccessToken;

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(interfaceUrl);

//設(shè)置連接超時(shí)時(shí)間

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;

//發(fā)送數(shù)據(jù)

using (Stream writer = request.GetRequestStream())

{

writer.Write(Bytes, 0, Bytes.Length);

writer.Close();

}

StringBuilder strb = new StringBuilder();

//接收數(shù)據(jù)

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錯(cuò)誤

{

// AccessToken = getAccessToken();

getzmAccessToken();

return requstZmToCreatMent(jsonStr);

}

else

{

if (strb.ToString() == "{\"errcode\":0,\"errmsg\":\"ok\"}")

{

return true;

}

else

{

return false;

}

}

}

catch (Exception exp)

{

return false;

}

}
