curl增加多个请求头的写法

public function add_brand()
{
    $header = array('Content-Type:application/json','charset:utf-8','groupName:ns-v7g15','accountId:1626231450425742965');

    $list = db('user')->where(['apply_sj_status' => 2])->field('id,username')->select();
    foreach ($list as $k=>$val){
       // $threeDS2RequestData['name'] = (string)$val['username'];
        $threeDS2RequestData['name'] = "测试品牌11";
        $url = 'http://api.kingdee.com/jdy/basedata/material_brand_save?access_token='.$token;
        $result = $this->curl_request($url,json_encode($threeDS2RequestData),'POST',$header);
