### Payment API Integration Example

Source: https://github.com/yunzhanghuopen/sdk-java/blob/master/README.md

Demonstrates how to configure the SDK and perform a bank card real-time order request.

```java

import com.yunzhanghu.sdk.base.YzhConfig;
import com.yunzhanghu.sdk.base.YzhConfig.SignType;
import com.yunzhanghu.sdk.base.YzhRequest;
import com.yunzhanghu.sdk.base.YzhResponse;
import com.yunzhanghu.sdk.payment.PaymentClient;
import com.yunzhanghu.sdk.payment.domain.CreateBankpayOrderRequest;
import com.yunzhanghu.sdk.payment.domain.CreateBankpayOrderResponse;
import org.junit.Assert;
import org.junit.Test;

// 接口调用示例
public class Payment {

    // 银行卡实时下单接口
    @Test
    public void bankCardOrder() {
        try {
            YzhConfig config = getYzhConfig();
            PaymentClient client = new PaymentClient(config);
            // 设置连接超时时间，默认 30S
            client.setSocketTimeout(30*1000);// 单位：毫秒

            CreateBankpayOrderRequest request = new CreateBankpayOrderRequest();
            request.setOrderId("202009010016562012987");
            request.setDealerId(config.getDealerId());
            request.setBrokerId(config.getBrokerId());
            request.setRealName("张三");
            request.setCardNo("6228888888888888888");
            request.setPhoneNo("188****8888");
            request.setIdCard("11010519491231002X");
            request.setPay("100.00");
            request.setPayRemark("");
            request.setNotifyUrl("https://www.example.com");

            // 调用银行卡实时下单接口
            YzhResponse<CreateBankpayOrderResponse> response = client.createBankpayOrder(YzhRequest.build(request));
            System.out.println(response);

            Assert.assertTrue(response.isSuccess());

            CreateBankpayOrderResponse data = response.getData();
            System.out.println(data);
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

    // 获取基础配置
    private static YzhConfig getYzhConfig() {
        YzhConfig config = new YzhConfig();
        // 方式一：从配置文件获取
        // config = YzhConfig.loadConfig("yzh.properties");

        // 方式二：自定义配置
        config.setDealerId("");
        config.setBrokerId("");
        config.setSignType(SignType.RSA);
        config.setYzh3DesKey("");
        config.setYzhAppKey("");
        config.setYzhRsaPrivateKey("");
        config.setYzhRsaPublicKey("");
        config.setYzhUrl("https://api-service.yunzhanghu.com");
        return config;
    }
}
```

### Maven Dependency Configuration

Source: https://github.com/yunzhanghuopen/sdk-java/blob/master/README.md

Add this dependency to your project's pom.xml file to use the SDK.

```xml
<dependency>
    <groupId>com.yunzhanghu.openapi</groupId>
    <artifactId>sdk</artifactId>
    <version>1.4.40-RELEASE</version>
</dependency>
```

--------------------------------

### Generate RSA Keys with OpenSSL

Source: https://github.com/yunzhanghuopen/sdk-java/blob/master/README.md

Commands to generate private and public keys for secure communication.

```bash
① ⽣成私钥 private_key.pem

OpenSSL-> genrsa -out private_key.pem 2048   // 建议密钥⻓度⾄少为 2048 位

OpenSSL-> pkcs8 -topk8 -inform PEM -in private_key.pem -outform PEM -nocrypt -out private_key_pkcs8.pem  // 将私钥转为 PKCS8 格式 

② ⽣成公钥⽂件 pubkey.pem

OpenSSL-> rsa -in private_key.pem -pubout -out pubkey.pem
```
