在我們購買商品或其他操作的時候，這時候微信公眾號會推送相關模版訊息。接下來簡單介紹開發流程：（本文以訂單推送為例）

測試號新建模版訊息

格式如下：

{{first.DATA}} 
使用者名稱：{{keyword1.DATA}} 
訂單號：{{keyword2.DATA}} 
訂單金額：{{keyword3.DATA}} 
商品資訊：{{keyword4.DATA}} 
{{remark.DATA}

注：這裡會生成一個模版ID，後面會用到

訂單完成模版訊息資料

@Data
public class OrderData {
    private DataInfo first;
    private DataInfo keyword1;
    private DataInfo keyword2;
    private DataInfo keyword3;
    private DataInfo keyword4;
    private DataInfo remark;

    public OrderData(DataInfo first, DataInfo keyword1, DataInfo keyword2, DataInfo keyword3, 
DataInfo keyword4, DataInfo remark) {
        this.first = first;
        this.keyword1 = keyword1;
        this.keyword2 = keyword2;
        this.keyword3 = keyword3;
        this.keyword4 = keyword4;
        this.remark = remark;
    }

    public OrderData(DataInfo first, DataInfo keyword1, DataInfo keyword2, DataInfo remark) {
        this.first = first;
        this.keyword1 = keyword1;
        this.keyword2 = keyword2;
        this.remark = remark;
    }
}

訂單完成模版訊息

public void sendOrderTemplateMessage(Order order) {
    AugeWechatUser wechatUser = augeWechatUserMapper.selectByPhone(order.getPhone());
String goodsInfo = "";
    for (AugeSaleItem augeSaleItem : order.getData()) {
        goodsInfo += augeSaleItem.getItemName() + "×" + augeSaleItem.getItemNum() + "
 
\n\t\t\t";
}
    DataInfo first = new DataInfo("恭喜你購買成功！", "#ff0000");
DataInfo keyword1 = new DataInfo(wechatUser.getNickName(), "#ff0000");
DataInfo keyword2 = new DataInfo(order.getOrderNumber(), "#ff0000");
DataInfo keyword3 = new DataInfo("￥" + order.getSumPrice() + "元", "#ff0000");
DataInfo keyword4 = new DataInfo(goodsInfo, "#ff0000");
DataInfo remark = new DataInfo("歡迎再次購買！", "#000000");

OrderData orderData = new OrderData(first, keyword1, keyword2, keyword3, keyword4, remark);
OrderTemplateMessage templateMessage = new OrderTemplateMessage();
templateMessage.setTouser(wechatUser.getId());
templateMessage.setTemplate_id(orderTemplateId);//模版ID
templateMessage.setData(orderData);

OkHttpUtil.getInstance().doPost(WechatConstant.getTemplateUrl(wechatAccessTokenService.takeAccessToken()), 
JSON.toJSONString(templateMessage));
}

OkHttpUtil

OkHttp是一個第三方類庫，用於Android中請求網路。

public String doPost(String url, String param) {
        MediaType JSON = MediaType.parse("application/json; charset=utf-8");
RequestBody body = RequestBody.create(JSON, param);
Request request = new Request.Builder()
                .url(url)
                .post(body)
                .build();
Call call = okHttpClient.newCall(request);
        try {
            Response response = call.execute();
            return response.body().string();
} catch (IOException e) {
            e.printStackTrace();
}
        return null;
}

注意配置訂單模版ID

@Value("#{setting.ordertemplateid}")
private String orderTemplateId;
