微信公众号开发之创建自定义菜单

微信菜单创建调用接口 

public static String menu_create_url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN";

菜单的创建需要传入access_token作为参数，还没获取access_token的小伙伴可参照微信公众号开发之获取access_token

在这里创建最基本的菜单实例：

public class Menu {
    private Button[] button;	//一级菜单数组，个数应为1~3个
    public Button[] getButton() {
        return button;
    }
    public void setButton(Button[] button) {
        this.button = button;
    }
}

public class Button {
    private String name;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

public class SubButton extends Button{
    private Button[] sub_button;
    public Button[] getSub_button() {
        return sub_button;
    }
    public void setSub_button(Button[] sub_button) {
        this.sub_button = sub_button;
    }
}

public class ClickButton extends Button{
    private String type;
    private String key;
    public String getKey() {
        return key;
    }
    public void setKey(String key) {
        this.key = key;
    }
    public String getType() {
        return type;
    }
    public void setType(String type) {
        this.type = type;
    }
}

public class ViewButton extends Button{
    private String type;
    private String url;
    public String getUrl() {
        return url;
    }
    public void setUrl(String url) {
        this.url = url;
    }
    public String getType() {
        return type;
    }
    public void setType(String type) {
        this.type = type;
    }
}

组装菜单数据

/**
 * 描述:菜单管理器类 </br>
 */
public class MenuManager {
    /**
     * 组装菜单数据
     * @return
     */
    public static Menu getMenu() {
        Menu menu = new Menu();
        ViewButton button11 = new ViewButton();
        button11.setName("如何使用");
        button11.setType("view");
        button11.setUrl(WXConstants.BASE_SERVER + "/wechat/toshopstep");
        ViewButton button12 = new ViewButton();
        button12.setName("联系我们");
        button12.setType("view");
        button12.setUrl(WXConstants.BASE_SERVER + "/wechat/tocontentus");
        SubButton button1 = new SubButton();
        button1.setName("关于我们");
        button1.setSub_button(new Button[]{button11,button12});        
        ViewButton button31 = new ViewButton();
        button31.setName("领取福利");
        button31.setType("view");
        button31.setUrl(WXConstants.BASE_SERVER + "/activity/xdou");
        ViewButton button32 = new ViewButton();
        button32.setName("人脸识别");
        button32.setType("view");
        button32.setUrl("https://open.weixin.qq.com/connect/oauth2/authorize?appid=" + WXConstants.APPID + "&redirect_uri=" + WXConstants.BASE_SERVER + "/wechat/check&response_type=code&scope=snsapi_base&state=BINDFACE#wechat_redirect");
        SubButton button3 = new SubButton();
        button3.setName("豆便利");
        button3.setSub_button(new Button[]{button31,button32});
        menu.setButton(new Button[]{button1,button3});
        return menu;
    }
}

创建菜单 （httpRequest方法参照微信公众号开发之获取access_token）

    /**
     * 创建菜单
     * @param menu 菜单实例
     * @param accessToken 有效的access_token
     * @return 0表示成功，其他值表示失败
     */
    public static int createMenu(Menu menu, String accessToken) {
        int result = 0;
        // 拼装创建菜单的url
        String url = WXConstants.menu_create_url.replace("ACCESS_TOKEN", accessToken);
        // 将菜单对象转换成json字符串
        String jsonMenu = JSONObject.fromObject(menu).toString();
        // 调用接口创建菜单
        JSONObject jsonObject = httpRequest(url, "POST", jsonMenu);
        if (null != jsonObject) {
            if (0 != jsonObject.getInt("errcode")) {
                result = jsonObject.getInt("errcode");
                log.error("创建菜单失败 errcode:{} errmsg:{}", jsonObject.getInt("errcode"), jsonObject.getString("errmsg"));
            }
        }
        return result;
    }

main方法测试：

    private static Logger log = LoggerFactory.getLogger(MenuManager.class);
    public static void main(String[] args) {
        // 通过缓存获取access_token
        Map<String,Object> map = AccessTokenCache.getInstance().getAcessTokenAndExpiresIn(WXConstants.APPID, WXConstants.APPSECRET);
        String accessToken = (String)map.get("access_token");
        if (!accessToken.equals("")) {
            // 调用接口创建菜单
            int result = WeiXinUtil.createMenu(getMenu(), accessToken);
            // 判断菜单创建结果
            if (0 == result)
                log.info("菜单创建成功！");
            else
                log.info("菜单创建失败，错误码：" + result);
        }
    }

测试结果：

当然只是测试的话，还有更简单的方式，就是通过微信公众平台的测试接口https://mp.weixin.qq.com/debug

先获取access_token

然后复制获取到的access_token，再创建菜单（菜单是以json封装的，具体可参考微信公众平台）

返回如下结果，则说明创建成功
