调用获取RSA公钥API
https://pay.weixin.qq.com/wiki/doc/api/tools/mch_pay.php?chapter=24_7
1.获取PKCS#1格式的公钥
public static void getPublicKey() throws Exception {
String nonce_str= MD5Utils.getMessageDigest(String.valueOf(new Random().nextInt(10000)).getBytes());//随机数
//签名数据
Map<String, String> packageParams = new HashMap<>();
packageParams.put("mch_id", MERID);//微信支付分配的商户号
packageParams.put("nonce_str",nonce_str);//随机字符串，不长于32位。推荐随机数生成算法
packageParams.put("sign_type", "MD5");//签名类型，目前支持HMAC-SHA256和MD5，默认为MD5
// 把数组所有元素，按照“参数=参数值”的模式用“&”字符拼接成字符串
String prestr = PayUtil.createLinkString(packageParams);
//MD5运算生成签名，这里是第一次签名，用于调用统一下单接口
String sign = PayUtil.sign(prestr, SIGNKEY, "utf-8").toUpperCase();
//封装xml报文
String xml="<xml>"+
"<mch_id>"+MERID+"</mch_id>"+
"<nonce_str>"+nonce_str+"</nonce_str>"+
"<sign>"+sign+"</sign>"+
"<sign_type>"+"MD5"+"</sign_type>"+
"</xml>";
String createOrderURL = "https://fraud.mch.weixin.qq.com/risk/getpublickey";//获取RSA加密公钥API
//调用统一下单接口，并接受返回的结果
System.out.println(xml);
String post = ClientCustomSSL.paybank(createOrderURL, xml);
System.out.println(post);
String postString = XML.toJSONObject(post).toString();
String wxinfo = postString.substring(postString.indexOf(":") + 1, postString.length() - 1);
System.out.println(wxinfo);
}
2.返回示例
<xml>
<return_code>SUCCESS</return_code>
<return_msg>OK</return_msg>
<result_code>SUCCESS</result_code>
<mch_id>XXXXXXXX</mch_id>
<pub_key>
-----BEGIN RSA PUBLIC KEY-----
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
-----END RSA PUBLIC KEY-----
</pub_key>
</xml>
3.转换PKCS公钥格式
filename ：为public.pem地址
PKCS#1 转 PKCS#8:
openssl rsa -RSAPublicKey_in -in <filename> -pubout
PKCS#8 转 PKCS#1:
openssl rsa -pubin -in <filename> -RSAPublicKey_out
需要安装openSSL,配置环境变量 需要区分系统
4.将得到的PKCS#8公钥转换为base64
public static String getRsa() throws Exception {
String encBankAcctNo = "JOKER"; //加密的银行账号、或者名称
String keyfile = "C:\\Users\\o\\Desktop\\WXCertUtil\\cert\\XXXXXXXXXX_cert\\pksc8_public.pem"; //读取PKCS8密钥文件
PublicKey pub=RSAUtil.getPubKey(keyfile,"RSA");
//用标准的RSA加密库对敏感信息进行加密，选择RSA_PKCS1_OAEP_PADDING填充模式（eg：Java的填充方式要选 " RSA/ECB/OAEPWITHSHA-1ANDMGF1PADDING"）
String rsa ="RSA/ECB/OAEPWITHSHA-1ANDMGF1PADDING";
byte[] estr=RSAUtil.encrypt(encBankAcctNo.getBytes(),pub,2048, 11,rsa); //对银行账号进行加密
encBankAcctNo =Base64.encode(estr);//并转为base64格式
return encBankAcctNo;
}
5.调用https://api.mch.weixin.qq.com/mmpaysptrans/pay_bank 接口实现微信支付到银行卡
@PostMapping("/paybankcard")
@ApiOperation("微信账户付款到银行卡")
public Result<String> payBankCard() throws Exception {
String nonce_str= MD5Utils.getMessageDigest(String.valueOf(new Random().nextInt(10000)).getBytes());//随机数
int randomNum = (int) (Math.random() * 1999+5000);
//"商户企业付款单号";
String partner_trade_no = TimeUtils.getSysTime("yyyyMMddHHmmss") + randomNum;//生成订单号
String enc_bank_no = "XXXXXXXXX";
String enc_true_name = "XXXXXXXXXX";
String bank_code = "1005";
int amount = 100;
String desc = "测试到账";
//签名数据
Map<String, String> packageParams = new HashMap<>();
packageParams.put("mch_id",MERID);
packageParams.put("partner_trade_no",partner_trade_no);
packageParams.put("nonce_str",nonce_str);
packageParams.put("enc_bank_no",enc_bank_no);
packageParams.put("enc_true_name",enc_true_name);
packageParams.put("bank_code", bank_code);
packageParams.put("amount",String.valueOf(amount));
packageParams.put("desc", desc);
// 把数组所有元素，按照“参数=参数值”的模式用“&”字符拼接成字符串
String prestr = PayUtil.createLinkString(packageParams);
//MD5运算生成签名，这里是第一次签名，用于调用统一下单接口
String sign = PayUtil.sign(prestr, SIGNKEY, "utf-8").toUpperCase();
LOGGER.info("sign="+sign);
//封装xml报文
String xml="<xml>"+
"<amount>"+amount+"</amount>"+
"<bank_code>"+bank_code+"</bank_code>"+
"<desc>"+desc+"</desc>"+
"<enc_bank_no>"+enc_bank_no+"</enc_bank_no>"+
"<enc_true_name>"+enc_true_name+"</enc_true_name>"+
"<mch_id>"+ MERID+"</mch_id>"+
"<nonce_str>"+nonce_str+"</nonce_str>"+
"<partner_trade_no>"+ partner_trade_no+"</partner_trade_no>"+
"<sign>"+sign+"</sign>"+
"</xml>";
String createOrderURL = "https://api.mch.weixin.qq.com/mmpaysptrans/pay_bank";//微信统一下单接口
//调用统一下单接口，并接受返回的结果
System.out.println(xml);
String post = ClientCustomSSL.doRefund(createOrderURL,xml);
String postString = XML.toJSONObject(post).toString();
String wxinfo = postString.substring(postString.indexOf(":") + 1, postString.length() - 1);
System.out.println(wxinfo);
return Result.success();
