本實例是為了實現在管理後台實現微信菜單的添加刪除管理。
1、首先我們需要新建一個數據庫表用於存放menu菜單項
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
注意後台存menu菜單數據時，parentId=-1為一級菜單，或parendId為一級菜單的id作為該一級菜單下的二級菜單
2、在設置菜單時需要向微信接口傳menuJson字符串，所以要先拼接字符串，後台定義一個creatMenu()
public bool creatMenu() { string menuJson = ""; //這裡默認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字符串後調用微信接口創建菜單，需先獲取assess token,有關assess token獲取可參考：獲取AccessToken
/// <summary> /// 向微信服務器請求創建自定義菜單/// </summary> /// <param name="jsonStr"></param> /// <returns></returns> /// private bool requstZmToCreatMent(string jsonStr) { try { var AccessToken = "";//accesstoken需例外獲取，一般可開始時獲取後存數據庫，下次從數據庫取，注意accesstoken有效期為7200秒//聲明一個HttpWebRequest請求string interfaceUrl = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=" + AccessToken; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(interfaceUrl); //設置連接超時時間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; //發送數據using (Stream writer = request.GetRequestStream()) { writer.Write(Bytes, 0, Bytes.Length); writer.Close(); } StringBuilder strb = new StringBuilder(); //接收數據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; } }總結
