简介
微信小程序发送消息推送到用户微信上
基础流程
- 用户登录 :获取微信提供的openid
- 开发者去微信公众平台申请模板:获得模板id
- 授权消息推送:在小程序中调用wx.requestSubscribeMessage方法
- 成功后将数据保存到后台 消息推送表 中
- 在需要发送消息推送时:查询 消息推送表 如果有,使用 消息推送表 的数据调用接口subscribeMessage.send
细节流程
1.1用户微信登录(缓存opid)
1.2用户普通登录(无opid)
2 消息推送申请
2.1用户授权
2.1.1无opid(弹框要求 微信登录(类似第一步)
2.1.2有opid(继续
2.2获得了授权的模板id和opid
3传输到后台,后台存储到消息推送表,参数:模板id,opid,用户名称,身份证。默认参数:是否发送为N,创建时间,主键 ,发送时间为空
4后台定时器,查询到要发送的用户时,查询消息推送表,修改发送状态为Y,更新发送时间,然后发送微信小程序消息推送
代码
1用户微信小程序登录
wx.login({
success: res => {
console.log(res);
// 发送 res.code 到后台换取 openId, sessionKey, unionId
request.post('后台用小程序id和密钥获取Openid的接口.do', {
code: res.code
}).then((res) => {
console.log(res);
let result = JSON.parse(res.result);
wx.setStorageSync('openid',result.openid)//缓存openid
that.setData({
sessionKey: result.session_key
})
});
}
})
2 小程序消息推送授权
let templateId = '模板id';
wx.requestSubscribeMessage({
tmplIds: [templateId],
success (res) {
console.log(res);
if(res.模板id =='reject'){//被拒绝
}else{//同意
//获取缓存的openid,可能是之前用户登录时存放的
let opid = wx.getStorageSync('openid');
//如果有OPID,直接发送
if(opid){
//执行保存到后台的操作
that.saveSubMssage(opid,templateId);
}else{
wx.showToast({
title: '需要关联微信账号',
icon: 'success',
duration: 2000
})
//和登录授权一样
wx.login({
success: res => {
console.log(res);
// 发送 res.code 到后台换取 openId, sessionKey, unionId
request.post('后台换取用户id的接口', {
code: res.code
}).then((res) => {
//得到openid
let result = JSON.parse(res.result);
wx.setStorageSync('openid',result.openid)
opid=res.openid;
//执行保存到后台的操作
that.saveSubMssage(opid,templateId);
});
}
})
}
}
},
error(res){
console.log(res);
wx.showToast({
title: '授权出现错误',
icon: 'none',
duration: 2000
})
}
})
saveSubMssage(openid,tmplIds){
let that = this;
request.Post('后台保存用户同意消息推送的接口.do', {
openId: openid,//用户openid
templateId: tmplIds,//模板id
userName: encodeURI(that.data.userName),//中文乱码处理
idCard: that.data.idCard//身份证
}).then((res) => {
console.log(res);
wx.showToast({
title: '授权成功',
icon: 'success',
duration: 2000
})
//退出页面
setTimeout(function() {
wx.navigateBack({ changed: true });
}, 2000);
});
3 后台保存用户同意消息推送的接口
@RequestMapping(value="/SaveMessageAuthority.do" ,produces = "application/json;charset=UTF-8")
@ResponseBody
public String SaveMessageAuthority(String openId,String templateId,String userName ,String idCard) throws Exception {
try {
WeChatMessageAuthorityPO weChatMessageAuthority = new WeChatMessageAuthorityPO();
weChatMessageAuthority.setOpenId(openId);
weChatMessageAuthority.setTemplateId(templateId);
weChatMessageAuthority.setIdCard(idCard);
// String temp = request.getParameter("studentName");
if(StringUtils.isNotEmpty(userName)){
userName = java.net.URLDecoder.decode(userName,"UTF-8");
weChatMessageAuthority.setUserName(userName);
}
weChatMessageAuthority.setCreateDate(new Date());
weChatMessageAuthority.setIsSend(BaseStaticParameter.NO);
iWxMassageAuthorityService.saveOrUpdate(weChatMessageAuthority);
}catch (Exception e){
e.printStackTrace();
return "false";
}
return "true";
}
4 后台发送推送信息
public static boolean sendNearRemindMessage(String openId,String serveName,String windowName,String lineNumber,String waitNumber,String msg) throws Exception {
WxMaSubscribeMessage subscribeMessage = new WxMaSubscribeMessage();
//跳转小程序页面路径
subscribeMessage.setPage("pages/index/index");
//模板消息id
subscribeMessage.setTemplateId(WxMaConfiguration.templateId);
//给谁推送 用户的openid (可以调用根据code换openid接口)
subscribeMessage.setToUser(openId);

//把集合给大的data

return true;
