1.第一步準備好商戶的證書，在商戶後臺下載json

2第二步準備好微信RSA公鑰api

微信官方地址：https://pay.weixin.qq.com/wiki/doc/api/tools/mch_pay.php?chapter=24_7數組

這裏簡單實例展現，須要的自行拆分封裝微信

$mch_id     =   123456;//本身的商戶號
		$str        =   md5(rand(1000,9999));//隨機字符串
		$sign_type  =   "MD5";//加密類型
		$key        =   "abcde";//商戶的key
		$stringA    =   "mch_id={$mch_id}&nonce_str={$str}&sign_type={$sign_type}&key={$key}";
		$md5_str    =   MD5($stringA);//md5加密
		$sign       =   strtoupper($md5_str);//轉大寫
		$url        =   "https://fraud.mch.weixin.qq.com/risk/getpublickey";//微信生成RSA公鑰接口地址
$xml=<<<EOF
<xml>
<mch_id>{$mch_id}</mch_id>
<nonce_str>{$str}</nonce_str>
<sign_type>MD5</sign_type>
<sign>$sign</sign>
</xml>
EOF;
		$apiclient_key   =   './Xcxpay/Certificate/Jw/apiclient_cert.pem';//證書路徑 在商戶平臺下載
		$apiclient_cert  =   './Xcxpay/Certificate/Jw/apiclient_key.pem';//證書路徑 在商戶平臺下載
		$ch = curl_init();
		curl_setopt($ch, CURLOPT_TIMEOUT, 30);
		curl_setopt($ch,CURLOPT_URL, $url);
		curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,TRUE);
		curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,2);//嚴格校驗
		curl_setopt($ch, CURLOPT_HEADER, FALSE);
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
		//使用證書：cert 與 key 分別屬於兩個.pem文件
		curl_setopt($ch,CURLOPT_SSLCERTTYPE,'PEM');
//		curl_setopt($ch,CURLOPT_SSLCERT, 'apiclient_key證書的路徑');//上面第一步在商戶後臺下載的證書
		curl_setopt($ch,CURLOPT_SSLCERT, $apiclient_key);//上面第一步在商戶後臺下載的證書
		curl_setopt($ch,CURLOPT_SSLKEYTYPE,'PEM');
//		curl_setopt($ch,CURLOPT_SSLKEY, 'apiclient_cert證書的路徑');//上面第一步在商戶後臺下載的證書
		curl_setopt($ch,CURLOPT_SSLKEY, $apiclient_cert);//上面第一步在商戶後臺下載的證書
		curl_setopt($ch, CURLOPT_POST, TRUE);
		curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
		$data = curl_exec($ch);
		//返回結果
		if($data){
			curl_close($ch);
		} else {
			$error = curl_errno($ch);
			curl_close($ch);
		}
		libxml_disable_entity_loader(true);
		$result     =   json_decode(json_encode(simplexml_load_string($data, 'SimpleXMLElement', LIBXML_NOCDATA)), true);
		print_r($result);

成功後返回的數據app

把pub_key的內容保存成爲一個文件， 已 .pem後綴的文件 例如 wx_public.pem 等等須要用到這個文件curl

如：函數

再將wx_public.pem 格式轉換post

openssl rsa -RSAPublicKey_in -in 剛剛保存的文件 -pubout > 新的文件ui

獲得新的pem文件，等等要用到。這個文件主要是要來RAS加密 銀行卡號和姓名

 

新建一個類
