微信公众号之自定义菜单

自定义菜单，很嗨皮！

https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421141013

需要json传递数据！

微信提供三个接口，一个是创建菜单，一个是查看菜单，一个是删除菜单！

        if (preg_match('/(http:\/\/)|(https:\/\/)/i', C('SELF_HOSTNAME'))) {

    }
}

创建的时候会失败！

// 通过POST方式发送json数据
    static public function doPostJson($url = '', $param = [] ,$contentType = 'json') {
        $ch = curl_init();
        // 请求地址
        curl_setopt($ch, CURLOPT_URL, $url);
        // 请求参数类型
        $param = $contentType == 'json' ? urldecode(json_encode($param,JSON_UNESCAPED_UNICODE)) : http_build_query($param);
        // 关闭https验证
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        // post提交
        if($param){
            curl_setopt($ch, CURLOPT_POST, 1);
            curl_setopt($ch, CURLOPT_POSTFIELDS, $param);
        }
        // 返回的数据是否自动显示
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        // 执行并接收响应结果
        $output = curl_exec($ch);
        // 关闭curl
        curl_close($ch);
        return $output !== false ? $output : false;
}

这里的

 $param = $contentType == 'json' ? urldecode(json_encode($param,JSON_UNESCAPED_UNICODE)) : http_build_query($param);

是关键！！！

很有意思！！！

可以结合自动回复来实现更加复杂的功能！！！

菜单还可以跳转到小程序！！！

模板消息也可以跳转到小程序！！！
