}
DemoController 通过继承自 WeixinController 便拥有了接收消息和发送消息的便利方法
public class WeixinApiController extends ApiController {
public void index() {
render("/api/index.html");
}
/**
* 获取公众号菜单
*/
public void getMenu() {
ApiResult apiResult = MenuApi.getMenu();
if (apiResult.isSucceed())
renderText(apiResult.getJson());
else
renderText(apiResult.getErrorMsg());
}
/**
* 获取公众号关注用户
*/
public void getFollowers() {
ApiResult apiResult = UserApi.getFollows();
renderText(apiResult.getJson());
}
}
通过调用 MenuApi、UserApi 等 Api 的相关方法即可获取封装成 ApiResult 对象的结果，使用 render 系列方法即可快捷输出结果

欢迎更多同学来帮助完善！
由于开发过程中需要与微信平台在线交互，所以建立一个从微信平台到本地开发机器的通道用于调试是至关重要的，否则每次开发完新功能需要部署到公网进行调试将会是极其低效痛苦的事情。
调试环境搭建可以参考我的博客：传送门 也可以参考 jfinal-weixin 文档：传送门
此外：如果开发机器是 Linux 或是 Mac，直接使用如下 linux 命令与外网服务器建立反向隧道：ssh -R :80:localhost:本地端口 root@远程主机ip地址
