java实现微信公众号发送模版消息
前言:
在我们购买商品或其他操作的时候,这时候微信公众号会推送相关模版消息。接下来简单介绍开发流程:(本文以订单推送为例)
首先在测试号新建模版消息
格式如下:
{{first.DATA}}
用户名:{{keyword1.DATA}}
订单号:{{keyword2.DATA}}
订单金额:{{keyword3.DATA}}
商品信息:{{keyword4.DATA}}
{{remark.DATA}}
这里会生成一个模版ID,后面会用到
然后后台在上传订单接口,上传成功后调用发送模版消息,代码实现:
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("恭喜你购买成功!", "#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("欢迎再次购买!", "#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));
}
简单介绍 OkHttpUtil
OkHttp是一个第三方类库,用于Android中请求网络。
public String doPost(String url, String param) {
MediaType );
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;
}
注意配置订单模版ID
@Value("#{setting.ordertemplateid}")
private String orderTemplateId;
