微信公众号自定义菜单添加小程序链接 thinkphp5开发
 
微信自定义菜单里面添加小程序方法  getInstanceWchatMenu为读取数据库里的菜单
public function updateInstanceMenuToWeixin($instance_id)
{
    $menu = array();
    $menu_list = $this->getInstanceWchatMenu($instance_id);
    if (! empty($menu_list)) {
        
        foreach ($menu_list as $k => $v) {
            if (! empty($v)) {
                $menu_item = array(
                    'name' => ''
                );
                $menu_item['name'] = $v['menu_name'];
                
                // $menu_item['sub_menu'] = array();
                if (! empty($v['child'])) {
                    
                    foreach ($v['child'] as $k_child => $v_child) {
                        if (! empty($v_child)) {
                            $sub_menu = array();
                            $sub_menu['name'] = $v_child['menu_name'];
                            // $sub_menu['sub_menu'] = array();
                            if ($v_child['menu_event_type'] == 1) {
                                $sub_menu['type'] = 'view';
                                $sub_menu['url'] = $v_child['menu_event_url'];
                            }elseif($v_child['menu_event_type'] == 4){
                                // 小程序
                                $sub_menu['type'] = 'miniprogram';
                                $sub_menu['appid'] = $v_child['appid'];
                                $sub_menu['pagepath'] = $v_child['pagepath'];
                                $sub_menu['url'] = $v_child['menu_event_url'];
                            } else {
                                $sub_menu['type'] = 'click';
                                $sub_menu['key'] = $v_child['menu_id'];
                            }
                            
                            $menu_item['sub_button'][] = $sub_menu;
                        }
                    }
                } else {
                    if ($v['menu_event_type'] == 1) {
                        $menu_item['type'] = 'view';
                        $menu_item['url'] = $v['menu_event_url'];
                    }elseif($v['menu_event_type'] == 4){
                        // 小程序
                        $menu_item['type'] = 'miniprogram';
                        $menu_item['appid'] = $v['appid'];
                        $menu_item['pagepath'] = $v['pagepath'];
                        $menu_item['url'] = $v['menu_event_url'];
                    } else {
                        $menu_item['type'] = 'click';
                        $menu_item['key'] = $v['menu_id'];
                    }
                }
                $menu[] = $menu_item;
            }
        }
    }
    $menu_array = array();
    $menu_array['button'] = array();
    foreach ($menu as $k => $v) {
        $menu_array['button'][] = $v;
    }
    // 汉字不编码
    $menu_array = json_encode($menu_array);
    // 链接不转义
    $menu_array = preg_replace_callback("/\\\u([0-9a-f]{4})/i", create_function('$matches', 'return mb_convert_encoding(pack("H*", $matches[1]), "UTF-8", "UCS-2BE");'), $menu_array);
    return $menu_array;
}
生成菜单 $jsonmenu这个是上面方法生成菜单的数组
public function menu_create($jsonmenu)
{
    $url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=%s";
    $result = $this->get_url_return($url, $jsonmenu);
    return $result;
}
 
 
private function get_url_return($url, $data = '', $needToken = false)
{
    // 第一次为空，则从文件中读取
    if (empty($this->token)) {
        $this->token = cache::get('token-' . $this->author_appid);
    }
    // 为空则重新取值
    if (empty($this->token) or $needToken) {
        
        $this->get_access_token();
        $this->token = cache::get('token-' . $this->author_appid);
    }
    $newurl = sprintf($url, $this->token);
    $curl = curl_init(); // 创建一个新url资源
    curl_setopt($curl, CURLOPT_URL, $newurl);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
    if (! empty($data)) {
        curl_setopt($curl, CURLOPT_POST, 1);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
    }
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    $AjaxReturn = curl_exec($curl);
    // curl_close();
    $strjson = json_decode($AjaxReturn);
    if (! empty($strjson->errcode)) {
        switch ($strjson->errcode) {
            case 40001:
                return $this->get_url_return($url, $data, true); // 获取access_token时AppSecret错误，或者access_token无效
                break;
            case 40014:
                return $this->get_url_return($url, $data, true); // 不合法的access_token
                break;
            case 42001:
                return $this->get_url_return($url, $data, true); // access_token超时
                break;
            case 45009:
                return json_encode(array(
                    "errcode" => - 45009,
                    "errmsg" => "接口调用超过限制：" . $strjson->errmsg
                ));
                break;
            case 41001:
                return json_encode(array(
                    "errcode" => - 41001,
                    "errmsg" => "缺少access_token参数：" . $strjson->errmsg
                ));
                break;
            default:
                return json_encode(array(
                    "errcode" => - 41000,
                    "errmsg" => $strjson->errmsg
                )); // 其他错误，抛出
                break;
        }
    } else {
        return $AjaxReturn;
    }
}
