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
