最近代码出现分享问题，360云盘宣布混不下去，所有分享的连接都失效了，最近有时间会把代码转移到百度云，再把文章的代码补回去
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
/// <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
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
