1 添加一個小程序的消息模板，獲取到模板id，存儲到數據庫中，方便以后修改調用
2. https://developers.weixin.qq.com/miniprogram/dev/api-backend/open-api/template-message/templateMessage.send.html 小程序模板消息 官網文檔，直接調用send方法就行
這里有個坑，就是 form_id, 這個是用戶觸發表單事件的表單id,需要存儲到數據庫中，給這個表單提交以后的數據，添加一個字段叫做form_id（7天過期）， 這個formid 是和提交時的openid有關聯的，只能是提交的那個人才能用，別人用不了
也就是說，想要給誰發送模板消息，就要存儲誰的form_id。
例如 劍聖給守望者提交了一個 愛你呦 的表單(數據庫里會存儲這個表單的form_id)，但是守望者回復這個表單，並且向給 劍聖發送一個提醒的模板消息，就需要從劍聖提交的表單中獲取存儲的form_id，然后拼接url，發送post請求才能成功
守望者提交表單時的 form_id，只能給守望者自己發送模板消息
3. 代碼正文：
劍聖端：
Form表單屬性
bindsubmit="sendClick" 提交方法
report-submit="true" 必須有，用來獲取form_id
button
formType="submit" 使用這個屬性，進行表單提交，不用bindtap提交
Wxml:
<form bindsubmit="sendClick" bindreset="inputReset" report-submit="true">
<input focus="true" name="send-input" adjust-position='{{false}}' value='{{inputValue}}' bindfocus='focus' bindblur='blur' bindconfirm="sendClick" bindinput="getcontent" />
<image src='./../../../centent/img/camera.png' bindtap="chooseBanner"></image>
<button formType="submit" bindtap="addquestion">發送</button>
</form>
Js:
sendClick: function(e) {
var formId = e.detail.formId;//獲取form_id,存儲到數據庫
hcxcx.requestPost(hcxcx.apiUrl.addquestion, { formId : formId },function(){
})
}
守望者端：
執行回復操作，C#代碼：
//發送模板消息
Public void Addquestion(){
//獲取用戶的formid，這個就是劍聖端提交保單時存儲的formId
var list = questionbll.GetList("IsNoTeam:1,MemberId:'" + memberid + "',XcxFormIdNoNull:1");
var fid = list.OrderByDescending(x => x.CreateTime).FirstOrDefault().XcxFormId;
var openid=memberid.openid;//這個是需要發送的用戶(劍聖的openid，必須是小程序的openid)
//拼接模板消息主體
XcxRequestData xr = new XcxRequestData();
XcxRequestDataKeyword xcxRequest1 = new XcxRequestDataKeyword();
xcxRequest1.value = createTime.ToString("yyyy-MM-dd HH:mm:ss");
XcxRequestDataKeyword xcxRequest2 = new XcxRequestDataKeyword();
xcxRequest2.value = user.RealName;
XcxRequestDataKeyword xcxRequest3 = new XcxRequestDataKeyword();
xcxRequest3.value = "尊敬的用戶您好,您的咨詢已經被" + user.RealName + "解答,請及時查看";
xr.keyword1 = xcxRequest1;
xr.keyword2 = xcxRequest2;
xr.keyword3 = xcxRequest3;
//獲取消息模板
TemplateMesEntity templateMesEntity = templateMesCache.GetEntityByTeamIdAndTypeId(teamid.ToInt(), 30);
//延遲4秒發送，否則蘋果收不到消息
System.Timers.Timer timer = new System.Timers.Timer(4000);
timer.Elapsed += delegate (object sender, System.Timers.ElapsedEventArgs e)
{
timer.Enabled = false;
XcxSendTemplateMsg xcxSend = new XcxSendTemplateMsg();
xcxSend.form_id = fid;
xcxSend.page = "pages/GroupTools/UserClient/UserClient";
xcxSend.template_id = templateMesEntity.TemplateId;
xcxSend.touser = openid;
xcxSend.data = xr;
XcxSendTemplateMsg(xcxSend);
};
timer.Enabled = true;
