微信接口文档：调用微信服务消息的请求接口为：还有一个地址为微信公众号的消息推送接口：这里用服务消息的接口而不是公众号消息推送的接口，公众号接口需要付费开通权限关于服务推送form_id问题：
form_id有时效性，网上有说7天，但文档中没有维护。form_id用过一次就失效。form_id要真机提供才有效1.模板实体类
publicclassTemplateData{privateStringvalue;//color在服务消息通知中废弃，但在公众号消息通知仍存在privateStringcolor;publicTemplateData(Stringvalue,Stringcolor){this.value=value;this.color=color;}//getset省略}publicclassTemplateMessage{/接收者openid/privateStringtouser;/所需下发的模板消息的id/privateStringtemplateId;/小程序要跳转的页面url/privateStringpage;/表单提交场景下，为submit事件带上的formId；支付场景下，为本次支付的prepay_id/privateStringformId;/模板数据/privateMapString,TemplateDatadata;/模板需要放大的关键词，不填则默认无放大/privateStringemphasiseyword;//getset省略}2.获取token
publicclassAccessTokenRequestHandlerextendsRequestHandler{publicAccessTokenRequestHandler(HttpServletRequestrequest,HttpServletResponseresponse){super(request,response);}privatestaticStringaccess_token="";/获取小程序凭证access_token@return/publicstaticStringgetMinAccessToken(){if("".equals(access_token)){//如果为空直接获取returngetMinTokenReal();}if(tokenIsExpire(access_token)){//如果过期重新获取returngetMinTokenReal();}returnaccess_token;}/实际获取小程序access_token的方法@return/protectedstaticStringgetMinTokenReal(){//获取token所需参数url,grant_type,appid,appsecret用自己的StringrequestUrl=TOKENURL+"?grant_type="+GRANT_TYPE+"&appid="+APPID+"&secret="+APPSECRET;StringresContent="";TenpayHttpClienthttpClient=newTenpayHttpClient();httpClient.setMethod("GET");httpClient.setReqContent(requestUrl);if(httpClient.call()){resContent=httpClient.getResContent();if(resContent.indexOf(ConstantUtil.ACCESS_TOKEN)0){access_token=JsonUtil.getJsonValue(resContent,ConstantUtil.ACCESS_TOKEN);}else{System.out.println("获取access_token值返回错误！！！");}}else{System.out.println("后台调用通信失败");System.out.println(httpClient.getResponseCode());System.out.println(httpClient.getErrInfo());//有可能因为网络原因，请求已经处理，但未收到应答。}returnaccess_token;}}3.发起https请求并获取结果
