微信提現+退款 · php常用實例

## 1、先建造一個公共方法、也可以用sdk中的代碼 ```php namespace app\api\controller; class common { private $key = ''; /**********下方代碼可以放到公共函數中**********/ /* * * 產生隨機字符串，不長于32位 * @param int $length * @return 產生的隨機字符串 */ public function getNonceStr($length = 32) { $chars = "abcdefghijklmnopqrstuvwxyz0123456789"; $str = ""; for ($i = 0; $i < $length; $i++) { $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1); } return $str; } /* * 生成簽名 * @return 簽名 */ public function makeSign($data) { //獲取微信支付秘鑰 $key = $this->key ; // 去空 $data = array_filter($data); //簽名步驟一：按字典序排序參數 ksort($data); $string_a = http_build_query($data); $string_a = urldecode($string_a); //簽名步驟二：在string后加入KEY //$config=$this->config; $string_sign_temp = $string_a . "&key=" . $key; //簽名步驟三：MD5加密 $sign = md5($string_sign_temp); // 簽名步驟四：所有字符轉為大寫 $result = strtoupper($sign); return $result; } //將一個數組轉換為 XML 結構的字符串 public function array2xml($arr, $level = 1) { $s = $level == 1 ? "<xml>" : ""; foreach ($arr as $tagname => $value) { if (is_numeric($tagname)) { $tagname = $value['TagName']; unset($value["TagName"]); } if (!is_array($value)) { $s .= "<{$tagname}>" . (!is_numeric($value) ? '<![CDATA[' : "") . $value . (!is_numeric($value) ? ']]>' : "") . "</{$tagname}>"; } else { $s .= "<{$tagname}>" . $this->array2xml($value, $level + 1) . "</{$tagname}>"; } } $s = preg_replace("/([\x01-\x08\x0b-\x0c\x0e-\x1f])+/", ' ', $s); return $level == 1 ? $s . "</xml>" : $s; } /* * 將xml轉為array * @param string $xml xml字符串 * @return array 轉換得到的數組 */ public function xml2array($xml) { libxml_disable_entity_loader(true); $result = json_decode(json_encode(simplexml_load_string($xml, "SimpleXMLElement", LIBXML_NOCDATA)), true); return $result; } } ``` ## 2、建立控制器進行退款退款的curl需要證書、所以這里我們單獨寫在了控制器中 ```php namespace app\api\controller; class Wxrefund { private $appid = ''; private $mch_id = ''; private $apiclient_cert = './wx/apiclient_cert.pem'; private $apiclient_key = './wx/apiclient_key.pem'; /* refund(支付訂單號,支付總金額,退款金額) */ public function refund($order_sn,$total_fee,$refund_fee) { $data = request()->param(); if ($refund_fee){ $out_trade_no = $order_sn;//商戶支付單號自定義而已 $out_refund_no = 'refund'.time();//商戶退款單號自定義而已 $common=new common;//調用公共方法 //統一下單退款參數構造 $unifiedorder = array( 'appid' => $this->appid,//appid 'mch_id' => $this->mch_id,//商戶id 'nonce_str' => $common->getNonceStr(),//公共方法的隨機字符串 'out_trade_no' => $out_trade_no, //商戶訂單號 'out_refund_no' => $out_refund_no, //商戶退款單號 'total_fee' => $total_fee, //訂單金額需要整數依分為單位所以一般*100 'refund_fee' => intval(floatval($refund_fee)), //退款金額需要整數依分為單位所以一般*100 ); //生成簽名并加入數組 $unifiedorder['sign'] = $common->makeSign($unifiedorder); //根據數組轉成xml生成請求數據 $xmldata = $common->array2xml($unifiedorder); $opUrl = "https://api.mch.weixin.qq.com/secapi/pay/refund"; //吊起請求 $res = $this->curl_post_ssl_refund($opUrl, $xmldata); if (!$res) { return json_encode(array('status' => $status, 'result' => 'fail', 'errmsg' => "Can't connect the server")); } $content = $common->xml2array($res); if (strval($content['result_code']) == "FAIL" ) { return json_encode(array("status" => $status, "result" => 'fail', "errmsg" => strval($content["err_code_des"]))) ; } if (strval($content['return_code']) == "FAIL") { return json_encode(array("status" => $status, "result" => "fail", "errmsg" => strval($content['return_msg']))) ; } return "退款成功！"; }else{ return "不符合退款訂單！"; } } //curl public function curl_post_ssl_refund($url, $vars, $second=30,$aHeader=array()) { $ch = curl_init(); //超時時間 curl_setopt($ch,CURLOPT_TIMEOUT,$second); curl_setopt($ch,CURLOPT_RETURNTRANSFER, true); //這里設置代理，如果有的話 //curl_setopt($ch,CURLOPT_PROXY, "10.206.30.98"); //curl_setopt($ch,CURLOPT_PROXYPORT, 8080); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false); curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false);

curl_setopt($ch,CURLOPT_SSLKEY, $this->apiclient_key); //默認格式為PEM，可以注釋 //curl_setopt($ch,CURLOPT_SSLKEYTYPE,"PEM"); //默認格式為PEM，可以注釋 //curl_setopt($ch,CURLOPT_SSLKEYTYPE,"PEM"); /** * 補充當找不到ca根證書的時候還需要rootca.pem文件 * TODO 注意，微信給出的壓縮包中，有提示信息： * 由于絕大部分操作系統已內置了微信支付服務器證書的根CA證書, * 2018年3月6日后, 不再提供CA證書文件（rootca.pem）下載 */ /*----------第二種方式，兩個文件合成一個.pem文件----------------------------------------*/ //curl_setopt($ch,CURLOPT_SSLCERT,getcwd().'/all.pem');
