java小程序发送模板消息案例

java小程序发送模板消息

wxml:

发送模板消息

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) {
        console.log(e);
        var self = this;
        let method = 'get';
        let openid = 'obk-w5fq76shfannc_8l_6xeew0m';
        let _access_token = '14_z_mmrqz8f0lsoyphxhxlcy1qyqbiarasntyrchbqtknwdl3co46exwqsl8qr58yz01xme6shklgngkz1zhx0zqpnnsxjlgljdlejcr_qerpp76h-4zodzt4xtpqeaywhtnb_m-djizon3ayhzzjjafassc';
        let url = 'https://api.weixin.qq.com/cgi-bin/message/wxopen/template/sendaccess_token=' + _access_token;

                    "value": "测试数据一",

                    title: '发送成功',
                })
            },
            fail: function(err) {
                console.log('request fail ', err);
            },
            complete: function(res) {
                console.log("request completed!");
            }

        })

    }

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;
    }
}
