前言
本节主要是关注者(即用户)和用户组的管理,微信公众号提供了用户和用户组的管理,我们可以在微信公众号官方里面进行操作，添加备注和标签,以及移动用户组别，同时,微信公众号也提供了相应的接口另我们本地可以操作.我们主要是同步到本地,这样我们可以自己为用户定义更多的信息,以及与本地的业务更好的对接起来.
实现
一、关注与订阅事件
看到我们之前的消息处理类 我们需要扩展一个事件类,这个类与之前消息处理类是一样的分部类，同样来自Senpars微信的SDK
CustomMessageHandler.cs
/// <summary> /// 订阅（关注）事件 /// </summary> /// <returns></returns> public override IResponseMessageBase OnEvent_SubscribeRequest(RequestMessageEvent_Subscribe requestMessage) { var responseMessage = base.CreateResponseMessage<ResponseMessageText>(); responseMessage.Content = "欢迎关注"; return responseMessage; } /// <summary> /// 退订 /// 实际上用户无法收到非订阅账号的消息，所以这里可以随便写。 /// unsubscribe事件的意义在于及时删除网站应用中已经记录的OpenID绑定，消除冗余数据。并且关注用户流失的情况。 /// </summary> /// <returns></returns> public override IResponseMessageBase OnEvent_UnsubscribeRequest(RequestMessageEvent_Unsubscribe requestMessage) { var responseMessage = base.CreateResponseMessage<ResponseMessageText>(); responseMessage.Content = "有空再来"; return responseMessage; }
里面有2个事件,一个用户关注时触发,一个退订时候触发，所以基本我们无需要进行什么配置，只要加入这个类就可以了
二、本地数据库表
分组表
用户表
表字段是根据官网，用户管理对应字段而建立，基本与官方提供的用户信息是一样的，无非是存点用户的姓名，籍贯，头像，关注事件等
三、同步数据
这时我们就可以实现OnEvent_SubscribeRequest （关注时）的代码，基本没有实现难度，步骤如下：
- 获得OpenID（requestMessage.FromUserName）
- 调用信息接口（ UserInfoJson userJson = UserApi.Info(account.AccessToken, requestMessage.FromUserName);）
- 把信息添加到本地
- 启用订阅时回复的内容（回复在前面已经放出）
/// <summary> /// 订阅（关注）事件 /// </summary> /// <returns></returns> public override IResponseMessageBase OnEvent_SubscribeRequest(RequestMessageEvent_Subscribe requestMessage) { ValidationErrors errors = new ValidationErrors(); using (DBContainer db = new DBContainer()) { IWC_OfficalAccountsBLL account_BLL = new WC_OfficalAccountsBLL() { m_Rep = new WC_OfficalAccountsRepository(db) }; //获得当前公众号 WC_OfficalAccountsModel account = account_BLL.GetById(Id); //将用户提取到本地数据库 WC_UserModel userModel = new WC_UserModel(); IWC_UserBLL user_BLL = new WC_UserBLL() { m_Rep = new WC_UserRepository(db) }; user_BLL.Create(ref errors, userModel); UserInfoJson userJson = UserApi.Info(account.AccessToken, requestMessage.FromUserName); userModel.Id = ResultHelper.NewId; userModel.OpenId = userJson.openid; userModel.NickName = userJson.nickname; userModel.Sex = userJson.sex; userModel.Language = userJson.language; userModel.City = userJson.city; userModel.Province = userJson.province; userModel.Country = userJson.country; userModel.HeadImgUrl = userJson.headimgurl; userModel.SubscribeTime = ResultHelper.GetTimeByLong(userJson.subscribe_time); userModel.UnionId = userJson.unionid; userModel.Remark = userJson.remark; userModel.GroupId = userJson.groupid.ToString(); userModel.TagidList = string.Join(",", userJson.tagid_list.ToArray()); userModel.Subscribe = userJson.subscribe; userModel.OfficalAccountId = account.Id; IWC_MessageResponseRepository m_Rep = new WC_MessageResponseRepository(db); //订阅回复 List<WC_MessageResponse> messageList = m_Rep.GetSubscribeResponseContent(account.Id); if (messageList.Count() > 0) { if (messageList[0].Category == (int)WeChatReplyCategory.Text) { var responseMessage = base.CreateResponseMessage<ResponseMessageText>(); responseMessage.CreateTime = ResultHelper.NowTime; responseMessage.ToUserName = requestMessage.FromUserName; responseMessage.FromUserName = account.OfficalId; responseMessage.Content = messageList[0].TextContent; return responseMessage; } //图文方式 else if (messageList[0].Category == (int)WeChatReplyCategory.Image) { var responseMessage = CreateResponseMessage<ResponseMessageNews>(); foreach (var model in messageList) { responseMessage.Articles.Add(new Article() { Title = model.TextContent, Description = model.ImgTextContext, PicUrl = WebChatPara.SiteUrl + model.ImgTextUrl, Url = model.ImgTextLink }); } return responseMessage; }//一般很少用到 else if (messageList[0].Category == (int)WeChatReplyCategory.Voice) { var responseMessage = base.CreateResponseMessage<ResponseMessageMusic>(); responseMessage.Music.MusicUrl = WebChatPara.SiteUrl + messageList[0].MeidaUrl; responseMessage.Music.Title = messageList[0].TextContent; responseMessage.Music.Description = messageList[0].Remark; return responseMessage; } } var errorResponseMessage = requestMessage.CreateResponseMessage<ResponseMessageText>(); return errorResponseMessage; } }
退订事件：OnEvent_UnsubscribeRequest(退订没有什么代码，只是标记这个openID已经取消关注)
/// <summary> /// 订阅（关注）事件 /// </summary> /// <returns></returns> public override IResponseMessageBase OnEvent_SubscribeRequest(RequestMessageEvent_Subscribe requestMessage) { ValidationErrors errors = new ValidationErrors(); using (DBContainer db = new DBContainer()) { IWC_OfficalAccountsBLL account_BLL = new WC_OfficalAccountsBLL() { m_Rep = new WC_OfficalAccountsRepository(db) }; //获得当前公众号 WC_OfficalAccountsModel account = account_BLL.GetById(Id); //将用户提取到本地数据库 IWC_UserBLL user_BLL = new WC_UserBLL() { m_Rep = new WC_UserRepository(db) }; WC_UserModel userModel = user_BLL.GetById(Id); //标记为取消关注 userModel.Subscribe = 0; user_BLL.Edit(ref errors, userModel); var errorResponseMessage = requestMessage.CreateResponseMessage<ResponseMessageText>(); return errorResponseMessage; } }
后台管理
后台管理最直接的效益是分析统计用户的数据状况，这里只演示从服务器同步用户信息,其他都是以前写得发愁的，增删改查了
前端JS
$("#btnSync").click(function () {
var rows = $('#List').datagrid('getSelections');
if (rows.length > 0) {
var ids = rows.join(",");
$.each(rows, function (index, row) {
ids = ids + row.value + ",";
});
$.post("@Url.Action("SyncUser")?ids=" + ids, function (data) {
if (data.type == 1)
$("#List").datagrid('load');
$.messageBox5s('@Resource.Tip', data.message);
}, "json");
} else { $.messageBox5s('@Resource.Tip', '@Resource.PlaseChooseToOperatingRecords'); }
});
后端控制器代码
public JsonResult SyncUser(string ids,string officeId) { if (!string.IsNullOrWhiteSpace(ids)) { //填充数据 string[] arrs = ids.Split(','); List<BatchGetUserInfoData> list = new List<BatchGetUserInfoData>(); foreach (var m in arrs) { list.Add(new BatchGetUserInfoData() { openid = m }); } //批量同步数据 WC_OfficalAccountsModel accountModel = account_BLL.GetById(officeId); var batchList = Senparc.Weixin.MP.AdvancedAPIs.UserApi.BatchGetUserInfo(accountModel.AccessToken, list); foreach (var info in batchList.user_info_list) { WC_UserModel userModel = m_BLL.GetById(info.openid); if (userModel != null) { userModel.City = info.city; userModel.OpenId = info.openid; userModel.Id = info.openid; userModel.HeadImgUrl = info.headimgurl; userModel.Language = info.language; userModel.NickName = info.nickname; userModel.Province = info.province; userModel.Sex = info.sex; m_BLL.Edit(ref errors, userModel); } } LogHandler.WriteServiceLog(GetUserId(), "Ids:" + ids, "成功", "删除", "WC_User"); return Json(JsonHandler.CreateMessage(1, Resource.SaveSucceed)); } else { return Json(JsonHandler.CreateMessage(0, Resource.SaveFail)); } }
代码简单易懂：通过OpenID到公众号同步到数据，再将本地数据修改
同步接口在Senparc WX SDK下的Senparc.Weixin.MP.AdvancedAPIs UserApi
同时这个类也提供了：获取用户信息，获取关注者OpenId信息，修改关注者备注信息，批量获取用户基本信息
