    java小程序发送模板消息

    wxml:

    wxss:

    .modelbutton{
        margin-top:50%;
        width: 50%;
    }

    js前端发送模板消息:

    注意:每个小程序的openid都是不一样的,这里使用的是我的小程序的openid,应替换为自己小程序的openid。

    关于解密openid参考我的另一篇博客:https://blog.csdn.net/long_yi_1994/article/details/82977603

        testsubmit: function(e) {

            let url = 'https://api.weixin.qq.com/cgi-bin/message/wxopen/template/sendaccess_token=' + _access_token;

            })
    
        }

    java代码后台发送模板消息:

    后端发送模板消息需要获取前端表单提交的formid

    controller:

        @getmapping("/publishmodelmessage")
        public string publishmodelmessage(@requestparam(required = false) string formid,@requestparam(required = false) string openid,httpservletresponse response){
            openid = "ok_7b4mgyt6l9drxwinxjeecb_no";
            token token = commonutil.gettoken("wxe07fe139e9473040","0881d4dc47cd36cac667264238ad0bf2");
            system.out.println(token.getaccesstoken());
            wxmssvo wxmssvo = new wxmssvo();
            wxmssvo.settemplate_id("pz-qulr4atcagbacomjh09u0bava_st-lncp5jv7pcs");
            wxmssvo.settouser(openid);
            wxmssvo.setpage("pages/index/index");
            wxmssvo.setrequest_url("https://api.weixin.qq.com/cgi-bin/message/wxopen/template/sendaccess_token=" + token.getaccesstoken());
            wxmssvo.setform_id(formid);
            list list = new arraylist<>();
            list.add(new templatedata("通知","#ffffff"));
            list.add(new templatedata("李银龙","#ffffff"));
            list.add(new templatedata("发布成功","#ffffff"));
            list.add(new templatedata(new date().tostring(),"#ffffff"));
            list.add(new templatedata("日常加班","#ffffff"));
            list.add(new templatedata("深圳市方寸科技服务有限公司","#ffffff"));
            wxmssvo.setparams(list);
            commonutil.sendtemplatemessage(wxmssvo);
            return null;
        }

    工具类commonutil:

    public class commonutil {    
        public final static string token_url = "https://api.weixin.qq.com/cgi-bin/tokengrant_type=client_credential&appid=appid&secret=appsecret";
    //获取小程序token
        public static token gettoken(string appid, string appsecret) {
            token token = null;
            string requesturl = token_url.replace("appid", appid).replace("appsecret", appsecret);
            // 发起get请求获取凭证
            jsonobject jsonobject = httpsrequest(requesturl, "get", null);
    
            if (null != jsonobject) {
                try {
                    token = new token();
                    token.setaccesstoken(jsonobject.getstring("access_token"));
                    token.setexpiresin(jsonobject.getinteger("expires_in"));
                } catch (jsonexception e) {
                    token = null;
                    // 获取token失败
                    log.error("获取token失败 errcode:{} errmsg:{}", jsonobject.getinteger("errcode"), jsonobject.getstring("errmsg"));
                }
            }
            return token;
        }
    //发送模板消息
        public static string sendtemplatemessage(wxmssvo wxmssvo) {
            string info = "";
            try {
                //创建连接
                url url = new url(wxmssvo.getrequest_url());
                httpurlconnection connection = (httpurlconnection) url.openconnection();
                connection.setdooutput(true);
                connection.setdoinput(true);
                connection.setrequestmethod("post");
                connection.setusecaches(false);
                connection.setinstancefollowredirects(true);
                connection.setrequestproperty("content-type", "application/x-www-form-urlencoded");
                connection.setrequestproperty("content-type", "utf-8");
                connection.connect();
                //post请求
                dataoutputstream out = new dataoutputstream(connection.getoutputstream());
                jsonobject obj = new jsonobject();
    
                obj.put("access_token", wxmssvo.getaccess_token());
                obj.put("touser", wxmssvo.gettouser());
                obj.put("template_id", wxmssvo.gettemplate_id());
                obj.put("form_id", wxmssvo.getform_id());
                obj.put("page", wxmssvo.getpage());
    
                jsonobject jsonobject = new jsonobject();
    
                for (int i = 0; i < wxmssvo.getparams().size(); i++) {
                    jsonobject datainfo = new jsonobject();
                    datainfo.put("value", wxmssvo.getparams().get(i).getvalue());
                    datainfo.put("color", wxmssvo.getparams().get(i).getcolor());
                    jsonobject.put("keyword" + (i + 1), datainfo);
                }
    
                obj.put("data", jsonobject);
                out.write(obj.tostring().getbytes());
                out.flush();
                out.close();
    
                //读取响应
                bufferedreader reader = new bufferedreader(new inputstreamreader(connection.getinputstream()));
                string lines;
                stringbuffer sb = new stringbuffer("");
                while ((lines = reader.readline()) != null) {
                    lines = new string(lines.getbytes(), "utf-8");
                    sb.append(lines);
                }
                info = sb.tostring();
                system.out.println(sb);
                reader.close();
                // 断开连接
                connection.disconnect();
            } catch (exception e) {
                e.printstacktrace();
            }
            return info;
        }
    
    
    }

    token类:

    public class token {
        //接口访问凭证
        private string accesstoken;
        //接口有效期,单位:秒
        private int expiresin;
        
        public string getaccesstoken() {
            return accesstoken;
        }
        public void setaccesstoken(string accesstoken) {
            this.accesstoken = accesstoken;
        }
        public int getexpiresin() {
            return expiresin;
        }
        public void setexpiresin(int expiresin) {
            this.expiresin = expiresin;
        }
    }

    模板消息请求参数封装类wxmssvo:

    public class wxmssvo {
       private string touser;
       private string template_id;
       private string page;
       private string form_id;
       private string access_token;
       private string request_url;
       private list params = new arraylist<>();
    }

    模板消息详细参数封装templatedata:

    public class templatedata {
        private string key;
        private string value;
        private string color;
    
        public templatedata(string value, string color) {
            this.value = value;
            this.color = color;
        }
    }
