近日，在开发“微信企业付款到银行卡”的功能。第一次接触“付款到银行卡“这一块的业务，查询了很多的博客资料以及走了很多的弯路。也发现“企业付款到银行卡”分享的博客并不多。特地写了该博客，希望对你们有帮助。个人浅薄的见解
资料下载：目前资料已经删除了，之前有网友吐槽说：资料不全；也有很多网友加了我qq拿资，咨询怎么做，目前已经解答了有50多位网友的问题了，本人的精力有限，没办法顾及所有网友的问题，所以源码将不再开源。如果有需要加我qq:924155240。发个15~20块吃饭钱，可以把源码发给你+稍稍解答问题
一、企业付款到银行卡API
https://pay./wiki/doc/api/tools/mch_pay.php?chapter=24_2
二、开发准备
（1）证书的准备：java开发需要用到：apiclient_cert.p12证书的，在微信商户平台(pay.)–>账户设置–>API安全–>证书中下载的 。
【何时用到证书？】与支付不一样，企业支付功能在发送post请求的时候，需要加载自己的一个证书之后，带着证书去请求退款才可以。这里使用到证书–很多人不知道证书在哪里使用
（2）了解好数字签名 — 简单来解释，就是对自己要发送的数据进行加密处理、换句话说假如说你要传递A/B/C，就对这三者进行加密。初开发者的误区：不知道该加密什么数据、观看网上的博客胡乱进行签名，导致签名错误
【温馨提示：】数字签名是一般开发人员容易遇到的错误，记住“你没遇到数字签名错误，都不好意思说自己做过微信退款支付订单查询等功能”。
耐心解决就行
三、API截图解释
~ 接口说明 + 是否需要证书
~ 数字签名说明 – 记住一句话：对要传递的数据进行加密，你要传递什么就要签名什么
~ 证书说明
~ RSA加密公钥API
四、开发步骤如下
1、拼凑所需要传递的参数 map集合
2、对“收款方银行卡号”、“收款方用户名”进行“采用标准RSA算法”【付款到银行卡，这点最难】
3、根据要传递的参数生成自己的签名
4、把签名放到map集合中【因为签名也要传递过去，看API】
5、将当前的map结合转化成xml格式
6、发送请求到企业付款到银行的Api。发送请求是一个方法来的POST
7、解析返回的xml数据===》map集合
8、根据map中的result_code AND return_code来判断是否成功与失败
【注意：】这里有个很难很难的点就是RSA加密，在这里花费了很长的时间。特地贴出来跟大家讲一下
五、分步解决问题
第一个难点：获取公钥，并且转化成PSCK#8格式，详细过程参考下面这篇文章
/xiaozhegaa/article/details/79125430
第二个难点就是：RSA的加密、base的 加密。一般常见的加密有DEC加密、RSA加密、MD5加密、盐值加密等、有时间会写几篇加密的算法。这里给大家介绍贴出来两个工具类~~以下两个很长，可以不看。直接贴过去

然后就可以了，测试案例如下：
package com.fh.controller.weixin.junit;import java.security.PublicKey;import com.fh.util.weixin.Base64;import com.fh.util.weixin.RSAUtil;public class DemoTest {public static void main(String[] args) throws Exception {//需要被加密的字符串String encBankAcctName = "小郑"; //加密的银行账户名//定义自己公钥的路径String keyfile = "C:/book/pksc8_public.pem"; ////RSA工具类提供了，根据加载PKCS8密钥文件的方法PublicKey pub=RSAUtil.getPubKey(keyfile,"RSA"); //rsa是微信付款到银行卡要求我们填充的字符串String rsa ="RSA/ECB/OAEPWITHSHA-1ANDMGF1PADDING";// 进行加密byte[] estr=RSAUtil.encrypt(encBankAcctName.getBytes(),pub,2048, 11,rsa); //对银行账号进行base加密encBankAcctName =Base64.encode(estr);//并转为base64格式//测试输出System.out.println(encBankAcctName);}}
你能够正确的输出一串字符，说明你加密算法是没有问题的，如果有问题，会报错。输出不了
第三个难点：涉及到xml转化map，map转化成xml、签名、POST+证书发送。这个的话，详细可以查看这篇文件。里面的工具类都贴出来了，就是方便大家开发

六、正式的代码~ ~按照上述的8个步骤分别贴出来，很简单的
1、拼凑所需要传递的参数 map集合
2、对“收款方银行卡号”、“收款方用户名”进行“采用标准RSA算法”【付款到银行卡，这点最难】
3、根据要传递的参数生成自己的签名
4、把签名放到map集合中【因为签名也要传递过去，看API】
5、将当前的map结合转化成xml格式
6、发送请求到企业付款到银行的Api。发送请求是一个方法来的POST
7、解析返回的xml数据===》map集合
8、根据map中的result_code AND return_code来判断是否成功与失败
【注意第二步骤假设我们已经得到了公钥。至于如何获得，看第一个难点推荐的文章~自己去获取呗】
@Testpublic void test1(){//1~拼凑所需要传递的参数 map集合 ->查看API,传入参数哪些是必须的String encBankAcctNo = "62122601876****"; //加密的银行账号String encBankAcctName = "小郑"; //加密的银行账户名String bank_code = "1002"; //银行卡的编号~String desc ="测试提现到账通知";//转账描述String partner_trade_no = RandomStringGenerator.getRandomStringByLength(32);//生成随机号，//这里大家没有该方法的，建议使用UUID。随便输出不超过32位的字符串即可String nonce_str1 = RandomStringGenerator.getRandomStringByLength(32);//同上String mch_id = wxconfig.mch_id;//获取商务号的idString amount = "100"; //付款金额，单位是分//2.0 对“收款方银行卡号”、“收款方用户名”进行“采用标准RSA算法”【付款到银行卡，这点最难】//定义自己公钥的路径String keyfile = "C:/book/pksc8_public.pem"; //读取PKCS8密钥文件//RSA工具类提供了，根据加载PKCS8密钥文件的方法PublicKey pub=RSAUtil.getPubKey(keyfile,"RSA"); //rsa是微信付款到银行卡要求我们填充的字符串 String rsa ="RSA/ECB/OAEPWITHSHA-1ANDMGF1PADDING";try {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estr=RSAUtil.encrypt(encBankAcctName.getBytes("UTF-8"),pub,2048, 11,rsa);encBankAcctName = Base64.encode(estr); //对银行账户名加密并转为base64} catch (UnsupportedEncodingException e1) {// TODO Auto-generated catch blocke1.printStackTrace();} catch (Exception e1) {// TODO Auto-generated catch blocke1.printStackTrace();} //3.0 根据要传递的参数生成自己的签名SortedMap<Object,Object> parameters1 = new TreeMap<Object,Object>();parameters1.put("mch_id", mch_id);parameters1.put("partner_trade_no", partner_trade_no);parameters1.put("nonce_str", nonce_str1);parameters1.put("enc_bank_no", encBankAcctNo);parameters1.put("enc_true_name", encBankAcctName);parameters1.put("bank_code", bank_code);parameters1.put("amount", amount);parameters1.put("desc", desc);//直接调用签名方法，在上述第三个难点中可以找到哦String sign = SignUtils.creatSign("utf-8",parameters1);//4.0 把签名放到map集合中【因为签名也要传递过去，看API】parameters1.put("sign", sign);//5.0 将当前的map结合转化成xml格式 ~~ 在上述第三个难点推荐的文章有该方法String reuqestXml = WXPayUtil.getRequestXml(parameters1);//6.0 发送请求到企业付款到银行的Api。发送请求是一个方法来的POSTString wxUrl = "https://api.mch./mmpaysptrans/pay_bank"; //获取退款的api接口try {//调用方法发送了 -- 在上述第三个难点推荐的文章有该方法String weixinPost = ClientCustomSSL.doRefund(wxUrl, reuqestXml).toString();//7.0 解析返回的xml数据-- 在上述第三个难点推荐的文章有该方法EnterpriceToCustomerByCard enterpriceToCustomerByCard = EnterpricePayByBankXmlToBeanUtils.parseXmlToMap(weixinPost);//8.0根据map中的result_code AND return_code来判断是否成功与失败~~写自己的逻辑if("SUCCESS".equalsIgnoreCase(enterpriceToCustomerByCard.getResult_code()) && "SUCCESS".equalsIgnoreCase(enterpriceToCustomerByCard.getReturn_code())){//8表示退款成功//TODO写自己的逻辑//TODO 更改自己的申请单状态，生成记录等等}else{//9 表示退款失败//TODO 调用service的方法 ，存储失败提现的记录咯}} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}}
至此就可以实现了企业付款到银行卡的功能了。至于说银行卡编号之类的，去写一个switch判断，得到就可以了~~希望对大家有帮助
