    微信退款感觉比支付宝要容易一点

    官网api:https://pay.weixin.qq.com/wiki/doc/api/app/app.php?chapter=9_1

    直接上代码:

        public function refound(){
            $ref= md5("appid=1233213&mch_id=1233213&nonce_str=2194kfhaafaf384&op_user_id=1461000002"
                . "&out_refund_no=201704181551358393&out_trade_no=201704181551358393&refund_fee=1&total_fee=1"
                . "&key=yudsd7rfer7dsadh0UfdoReraRdsad4d");//sign加密MD5
            $refund=array(
                'appid'=>'12323123',
                'mch_id'=>'123213213',//商户号
                'nonce_str'=>'2194kfhaafaf384',//随机字符串
                'op_user_id'=>'1461000002',
                'out_refund_no'=>'201704181551358393',
                'out_trade_no'=>'201704181551358393',
                'refund_fee'=>'1',
                'total_fee'=>'1',
                'sign'=>$ref
            );
            $url="https://api.mch.weixin.qq.com/secapi/pay/refund";;//微信退款地址,post请求
            $xml=ToXml($refund);
            $ch=curl_init();
            curl_setopt($ch,CURLOPT_URL,$url);
            curl_setopt($ch,CURLOPT_HEADER,1);
            curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
            curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,1);//证书检查
            curl_setopt($ch,CURLOPT_SSLCERTTYPE,'pem');
            curl_setopt($ch,CURLOPT_SSLCERT,'plugins/payment/weixin/cert/apiclient_cert.pem');
            curl_setopt($ch,CURLOPT_SSLCERTTYPE,'pem');
            curl_setopt($ch,CURLOPT_SSLKEY,'plugins/payment/weixin/cert/apiclient_key.pem');
            curl_setopt($ch,CURLOPT_POST,1);
            curl_setopt($ch,CURLOPT_POSTFIELDS,$xml);
            $data=curl_exec($ch);
            if($data){ //返回来的是xml格式需要转换成数组再提取值,用来做更新
                curl_close($ch);
                dump($data);
            }else{
                $error=curl_errno($ch);
                echo "curl出错,错误代码:$error"."<br/>";
                echo "<a href='http://curl.haxx.se/libcurl/c/libcurs.html'>;错误原因查询</a><br/>";
                curl_close($ch);
                echo false;
            }
        }

    function ToXml($arr)
    {
    if(!is_array($arr)
    || count($arr) <= 0)
    {
    throw new WxPayException("数组数据异常!");
    }

    $xml = "<xml>";
    foreach ($arr as $key=>$val)
    {
    if (is_numeric($val)){
    $xml.="<".$key.">".$val."</".$key.">";
    }else{
    $xml.="<".$key."><![CDATA[".$val."]]></".$key.">";
    }
    }
    $xml.="</xml>";
    return $xml;
    }
     

    最主要证书的添加,基本上就可以走通的
