讲解修改分组名称和删除分组
获取分组列表需要用到的实体类
////// 微信分组类 /// public class WxGroupsInfo { public string Group_ID { get; set; }//分组编号 public string Group_Name { get; set; }//分组名称 public string Group_Count { get; set; }//分组人数 }
前台代码:
后台代码如下:
protected void Page_Load(object sender, EventArgs e) { if(!Page.IsPostBack) { BindGroupList(); this.DataBind(); } } private void BindGroupList() { WeiXinServer wxs = new WeiXinServer(); ///从缓存读取accesstoken string Access_token = Cache["Access_token"] as string; if (Access_token == null) { //如果为空,重新获取 Access_token = wxs.GetAccessToken(); //设置缓存的数据7000秒后过期 Cache.Insert("Access_token", Access_token, null, DateTime.Now.AddSeconds(7000), System.Web.Caching.Cache.NoSlidingExpiration); } string Access_tokento = Access_token.Substring(17, Access_token.Length - 37); string jsonres = ""; string content = Cache["AllGroups_content"] as string; if (content == null) { jsonres = "https://api.weixin.qq.com/cgi-bin/groups/get?access_token=" + Access_tokento; HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(jsonres); myRequest.Method = "GET"; HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse(); StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.UTF8); content = reader.ReadToEnd(); reader.Close(); //设置缓存的数据7000秒后过期 Cache.Insert("AllGroups_content", content, null, DateTime.Now.AddSeconds(7000), System.Web.Caching.Cache.NoSlidingExpiration); } //使用前需要引用Newtonsoft.json.dll文件 JObject jsonObj = JObject.Parse(content); int groupsnum = jsonObj["groups"].Count(); Listwxgrouplist = new List (); for (int i = 0; i < groupsnum; i++) { WxGroupsInfo wginfo = new WxGroupsInfo(); wginfo.Group_ID = jsonObj["groups"][i]["id"].ToString(); wginfo.Group_Name = jsonObj["groups"][i]["name"].ToString(); wginfo.Group_Count = jsonObj["groups"][i]["count"].ToString(); wxgrouplist.Add(wginfo); } this.RepeaterGroupList.DataSource = wxgrouplist; this.RepeaterGroupList.DataBind(); } /// /// 绑定事件 /// /// /// protected void RepeaterGroupList_ItemDataBound(object sender, RepeaterItemEventArgs e) { if(e.Item.ItemType==ListItemType.Item||e.Item.ItemType==ListItemType.AlternatingItem) { Label lbXuHao = e.Item.FindControl("lbXuHao") as Label; int num = 1; lbXuHao.Text = num.ToString(); for (int i = 0; i < this.RepeaterGroupList.Items.Count;i++ ) { num += 1; lbXuHao.Text = num.ToString(); } LinkButton LinkBtnDeleteGroup = e.Item.FindControl("LinkBtnDeleteGroup") as LinkButton; LinkBtnDeleteGroup.Attributes.Add("OnClick", "return confirm('您确定要删除该分组?删除后该分组内的人员即将恢复到默认分组!')"); } } ////// 执行事件 /// /// /// protected void RepeaterGroupList_ItemCommand(object source, RepeaterCommandEventArgs e) { //ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('删除接口已关闭!');location='WxGroupManageList.aspx';", true); if (e.CommandName == "DeleteGroups") { WeiXinServer wxs = new WeiXinServer(); string res = ""; ///从缓存读取accesstoken string Access_token = Cache["Access_token"] as string; if (Access_token == null) { //如果为空,重新获取 Access_token = wxs.GetAccessToken(); //设置缓存的数据7000秒后过期 Cache.Insert("Access_token", Access_token, null, DateTime.Now.AddSeconds(7000), System.Web.Caching.Cache.NoSlidingExpiration); } string Access_tokento = Access_token.Substring(17, Access_token.Length - 37); string posturl = "https://api.weixin.qq.com/cgi-bin/groups/delete?access_token=" + Access_tokento; //POST数据例子: POST数据例子:{"group":{"id":108}} string groupid = e.CommandArgument.ToString(); string postData = "{\"group\":{\"id\":\"" + groupid.ToString() + "\"}}"; res = wxs.GetPage(posturl, postData); ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('删除成功!由于缓存问题,您可能需要重新登录才能看到效果!');location='WxGroupManageList.aspx';", true); } } ////// 创建分组 /// /// /// protected void LinkBtnCreateGroup_Click(object sender, EventArgs e) { if (this.txtgroupsName.Value.ToString().Equals("分组名称")) { //// ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('不能为空!')", true); this.txtgroupsName.Focus(); return; } WeiXinServer wxs = new WeiXinServer(); string res = ""; ///从缓存读取accesstoken string Access_token = Cache["Access_token"] as string; if (Access_token == null) { //如果为空,重新获取 Access_token = wxs.GetAccessToken(); //设置缓存的数据7000秒后过期 Cache.Insert("Access_token", Access_token, null, DateTime.Now.AddSeconds(7000), System.Web.Caching.Cache.NoSlidingExpiration); } string Access_tokento = Access_token.Substring(17, Access_token.Length - 37); string posturl = "https://api.weixin.qq.com/cgi-bin/groups/create?access_token=" + Access_tokento; string postData = "{\"group\":{\"name\":\"" + this.txtgroupsName.Value.ToString().Trim() + "\"}}"; res = wxs.GetPage(posturl, postData); ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('创建成功!如未显示,请退出重新登录即可!');location='WxGroupManageList.aspx';", true); }
修改分组名称的页面
前台代码:
后台代码:
protected void Page_Load(object sender, EventArgs e) { if(!Page.IsPostBack) { if (Request.QueryString["id"] != null) { string group_id = Request.QueryString["id"].ToString(); string group_name = Request.QueryString["name"].ToString(); this.txtGroupId.Text = group_id.ToString(); this.txtGroupName.Text = group_name.ToString(); this.txtGroupName.Focus(); } } } ////// 设置 /// /// /// protected void LinkBtnSet_Click(object sender, EventArgs e) { if(String.IsNullOrWhiteSpace(this.txtGroupName.Text.ToString().Trim())) { ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('不能为空!');", true); this.txtGroupName.Focus(); return; } if (this.txtGroupName.Text.ToString().Trim().Length>30) { ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('组名称应在30个字符之内!');", true); this.txtGroupName.Focus(); return; } WeiXinServer wxs = new WeiXinServer(); string res = ""; ///从缓存读取accesstoken string Access_token = Cache["Access_token"] as string; if (Access_token == null) { //如果为空,重新获取 Access_token = wxs.GetAccessToken(); //设置缓存的数据7000秒后过期 Cache.Insert("Access_token", Access_token, null, DateTime.Now.AddSeconds(7000), System.Web.Caching.Cache.NoSlidingExpiration); } string Access_tokento = Access_token.Substring(17, Access_token.Length - 37); string posturl = "https://api.weixin.qq.com/cgi-bin/groups/update?access_token=" + Access_tokento; //POST数据例子:POST数据例子:{"group":{"id":108,"name":"test2_modify2"}} //string postData = "{\"group\":{\"name\":\"" + this.txtgroupsName.Value.ToString().Trim() + "\"}}"; string postData = "{\"group\":{\"id\":\"" + txtGroupId.Text.ToString() +"\",\"name\":\""+this.txtGroupName.Text.ToString()+"\"}}"; res = wxs.GetPage(posturl, postData); //使用前需药引用Newtonsoft.json.dll文件 JObject jsonObj = JObject.Parse(res); ///获取返回结果的正确|true|false, string isright = jsonObj["errcode"].ToString();//0 string istrueorfalse = jsonObj["errmsg"].ToString();//ok if (isright.Equals("0") && istrueorfalse.Equals("ok")) { ///修改成功之后,刷新父窗体,关闭本页 ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('修改成功!如未正常显示,属缓存问题,请重新登录即可!');window.opener.location.reload();this.close();", true); } else { ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('修改失败!');this.close();", true); } }
