#小程序端配置
1、进入微信公众平台,扫码登录
https://mp.weixin.qq.com/
2、获取appid和secret
小程序后台->开发->开发管理->开发设置->开发者 ID(需要配置在yml文件中)
3、配置模板
小程序后台->功能->订阅消息->我的模板->搜索需要模板(企业主体可以添加模板)->点击模板后面选用->选择关键词并填写场景->提交->点击详情->可以看到模板的详细信息->模板id需要配置在yml中。
需要注意的是thing最多接收20个字符,如果字符过多可配置character_string类型,该类型最多32个字符
后端代码配置
在对应yml中配置
spring-boot-plus:
wechat:
secret: 微信小程序中的secret
appid: 微信小程序中的appid
host: https://api.weixin.qq.com 固定配置
templateId1: 需要使用的模板id 该配置的key的值自定义,可配置多个
templateId2: xxx
path1: /xxx/index/tagview/meeting/meeting?id= 点击通知详情后的跳转路径,可配置多个
path2: /xxx/index/activity/activity?id=
增加订阅次数
前端调用弹出是否订阅时调用后台服务
1、controller
/**
* 订阅模板消息
*/
@PostMapping("/addSubscribe")
@ApiOperation(value = "订阅模板消息", notes = "订阅模板消息")
public ApiResult<Boolean> addSubscribe(@Valid @RequestBody AddSinosoftWxSubscribeParam addSinosoftWxSubscribeParam) throws Exception {
wxSubscribeServiceImpl.subscribe(addSinosoftWxSubscribeParam);
return ApiResult.ok();
}
2、后端接参AddSinosoftWxSubscribeParam
@Data
@Accessors(chain = true)
@ApiModel(value = "添加小程序订阅对象", description = "小程序订阅")
public class AddSinosoftWxSubscribeParam extends BaseEntity {
private static final long serialVersionUID = 1L;
@ApiModelProperty(value = "消息模板id集合")
private List<String> templateIds;
@ApiModelProperty(value = "openid")
private String openid;
@ApiModelProperty(value = "是否永久订阅 1:否 2:是")
private String isForever;
}
3、service
/**
* 增加订阅次数
*
* @param addSinosoftWxSubscribeParam
*/
public void subscribe(AddSinosoftWxSubscribeParam addSinosoftWxSubscribeParam) {
log.info("开始===微信增加订阅次数,addSinosoftWxSubscribeParam:[{}]", addSinosoftWxSubscribeParam);
// 获取当前登录
String loginUserId = RequestContext.getLoginUserId();
//String loginUserId = "1";
//获取用户openId
String openId = addSinosoftWxSubscribeParam.getOpenid();
//判断是否永久订阅
int isForever = Integer.parseInt(addSinosoftWxSubscribeParam.getIsForever());
//批量存库list
List<WxSubscribe> wxSubscribeList = new ArrayList<>();
//是否永久订阅
int isforever = Integer.parseInt(SubscribeTypeEnum.FOREVER.getValue());
//int isForever = 1;
for (String templateId : addSinosoftWxSubscribeParam.getTemplateIds()) {
//查找数据库中是否有该用户的记录
WxSubscribe wxSubscribe = wxSubscribeRepository.selectOne(templateId, loginUserId);
log.info("用户信息,wxSubscribe:[{}]", wxSubscribe);
//如果没有则新建用户
if (wxSubscribe == null) {
wxSubscribe = new WxSubscribe();
wxSubscribe.setUserId(Long.parseLong(loginUserId));
wxSubscribe.setTemplateId(templateId);
wxSubscribe.setWeChatOpenid(openId);
if (isForever == isforever) {
wxSubscribe.setIsForever(isforever);
} else {
wxSubscribe.setTotal(1);
}
//保存到数据库
//wxSubscribeMapper.insert(wxSubscribe);
} else {
log.info("[old-openid]" + wxSubscribe.getWeChatOpenid());
log.info("[new-openid]" + openId);
//判断是否永久订阅
if (isForever == isforever) {
wxSubscribe.setIsForever(isforever);
} else {
wxSubscribe.setTotal(wxSubscribe.getTotal() + 1);
}
// 更新openid
wxSubscribe.setWeChatOpenid(openId);
//保存到数据库
//wxSubscribeMapper.updateById(wxSubscribe);
}
wxSubscribeList.add(wxSubscribe);
}
wxSubscribeRepository.saveOrUpdateBatch(wxSubscribeList);
log.info("结束===微信增加订阅次数");
}
推送订阅信息
一般时通过时间或者调度进行调用服务,以下只进行服务实现展示
1、在domain层写send方法
public void send(String tempId, Map<String, Object> data, Long userId, String path) {
this.send(tempId, data, Collections.singletonList(userId), path);
}
/**
* 小程序通知发送
*
* @param tempId 通知模板
* @param data 模板参数 其中key对应模板thing、time等值 value对应值
* @param userIds 要发送的id
* @param path 点击消息后打开的小程序页面
*/
public void send(String tempId, Map<String, Object> data, List<Long> userIds, String path) {
log.info("开始===微信通知发送业务处理,tempId:[{}],data:[{}],userIds:[{}],path:[{}]", tempId, data, userIds, path);
//拼接模板参数
Map<String, Object> outMap = new HashMap<>();
for (Map.Entry<String, Object> entry : data.entrySet()) {
Map<String, Object> inMap = new HashMap<>();
inMap.put("value", entry.getValue());
outMap.put(entry.getKey(), inMap);
}
log.info("[userIds]" + userIds);
//是否永久订阅
int notForever = Integer.parseInt(SubscribeTypeEnum.NOTFOREVER.getValue());
int forever = Integer.parseInt(SubscribeTypeEnum.FOREVER.getValue());
//查找数据库中所有订阅了该模板的用户
List<WxSubscribe> tmpSinosoftWxSubscribes = wxSubscribeRepository.selectWxSubscribeList(tempId, userIds);
List<WxSubscribe> wxSubscribes = tmpSinosoftWxSubscribes.stream().filter(x -> (x.getIsForever() == forever || (x.getIsForever() == notForever && x.getTotal() > 0))).collect(Collectors.toList());
log.info("[wxSubscribes]" + wxSubscribes);
//订阅用户为空则不往下执行
if (CollectionUtil.isEmpty(wxSubscribes)) {
return;
}
//获取微信api调用token
String token = this.getToken();
//批量更新微信发送通知记录表
List<WxSendNoticeRecord> wxSendNoticeRecordList = new ArrayList<>();
//遍历订阅用户,逐一推送消息
for (WxSubscribe subscribeMessage : wxSubscribes) {
//模板id
String templateId = subscribeMessage.getTemplateId();
//构建消息实体
//Map<String,Object> resultMap = new HashMap<>();
JSONObject resultMap = new JSONObject();
//接收用户的openid
resultMap.put("touser", subscribeMessage.getWeChatOpenid());
//消息模板id(从小程序后台获取)
resultMap.put("template_id", templateId);
//点击消息后打开的小程序页面
resultMap.put("page", path);
log.info("[path]" + path);
resultMap.put("data", outMap);
//推送消息
JSONObject wxNoticeResult = this.sendMessage(token, resultMap.toString());
//数据库中的订阅次数-1
//如果是永久不需-1 非永久-1
int isForever = subscribeMessage.getIsForever();
if (isForever == notForever) {
subscribeMessage.setTotal(subscribeMessage.getTotal() - 1);
}
//拼接发送记录表
WxSendNoticeRecord wxSendNoticeRecord = new WxSendNoticeRecord();
wxSendNoticeRecord
.setUserId(subscribeMessage.getUserId())
.setTemplateId(templateId)
.setNoticemsg(data.toString())
.setErrcode(wxNoticeResult.getString("errcode"))
.setErrmsg(wxNoticeResult.getString("errmsg"));
wxSendNoticeRecordList.add(wxSendNoticeRecord);
//wxSubscribeMapper.updateById(subscribeMessage);
}
//批量更新剩余发送条数
wxSubscribeRepository.updateBatchById(wxSubscribes);
//批量更新发送记录
wxSendNoticeRecordRepository.saveBatch(wxSendNoticeRecordList);
log.info("结束===微信通知发送业务处理");
}
/**
* 发送消息
*
* @param token
* @param body
*/
private JSONObject sendMessage(String token, String body) {
log.info("开始===微信订阅推送,token:[{}],body:[{}]", token, body);
String url = this.host + "/cgi-bin/message/subscribe/send?access_token=" + token;
HttpRequest request = HttpRequest.post(url);
log.info("[body]" + body);
if (body != null) {
request.body(body);
}
request.contentType("application/json");
HttpResponse httpResponse = request.execute();
httpResponse.charset(StandardCharsets.UTF_8);
String result = httpResponse.body();
JSONObject object = JSON.parseObject(result);
log.info("开始===微信订阅推送,result:[{}]" + result);
return object;
}
/**
* 获取微信api凭证
*
* @return
*/
private String getToken() {
log.info("开始===微信获取token");
String url = this.host + "/cgi-bin/token?grant_type=client_credential&appid=" + this.appid + "&secret=" + this.secret;
HttpRequest req = HttpRequest.get(url);
HttpResponse resp = req.execute();
resp.charset(StandardCharsets.UTF_8);
String respBody = resp.body();
log.info("[respBody]" + respBody);
log.info("结束===微信获取token,result:[{}]", respBody);
JSONObject object = JSON.parseObject(respBody);
return object.getString("access_token");
}
前端也需进行调用接口(以下简单写)
1、首先小程序授权登陆获取 code
2、将 code 传给服务端 获取用户唯一标识 openId
3、通过代码起小程序消息订阅界面、用户点击确定ok,小程序工作结束文章来源:https://www.toymoban.com/news/detail-648680.html
