（微信支付）企业付款到银行卡

微信官方文档

https://pay.weixin.qq.com/wiki/doc/api/tools/mch_pay.php?chapter=24_2

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();

}
