java对接海康门禁人脸添加代码

对接海康门禁添加人脸需要使用海康门禁SDK，以下是Java调用海康门禁SDK实现对门禁设备添加人脸的示例代码：

import com.sun.jna.Native;
import com.sun.jna.Pointer;
import com.sun.jna.ptr.ByteByReference;
import com.sun.jna.ptr.IntByReference;

public class HikvisionFaceController {

    public interface HikvisionLibrary extends com.sun.jna.Library {
        HikvisionLibrary INSTANCE = (HikvisionLibrary) Native.loadLibrary("HCNetSDK", HikvisionLibrary.class);

        int NET_DVR_Init();

        int NET_DVR_Login_V40();

        int NET_DVR_Logout_V30();

        int NET_DVR_GetLastError();

        int NET_DVR_SetDVRConfig();

        int NET_DVR_GetDVRConfig();

        int NET_DVR_SendRemoteConfig();

        int NET_DVR_StopRemoteConfig();
    }

    public static void main(String[] args) {

        // 初始化SDK
        HikvisionLibrary.INSTANCE.NET_DVR_Init();

        // 登录门禁
        IntByReference lUserID = new IntByReference();
        HikvisionLibrary.NET_DVR_DEVICEINFO_V40 struDeviceInfo = new HikvisionLibrary.NET_DVR_DEVICEINFO_V40();
        lUserID.setValue(HikvisionLibrary.INSTANCE.NET_DVR_Login_V40("192.168.1.64", (short) 8000, "admin", "password", struDeviceInfo));

        // 添加人脸
        HikvisionLibrary.NET_DVR_XML_CONFIG_INPUT struInput = new HikvisionLibrary.NET_DVR_XML_CONFIG_INPUT();
        struInput.dwSize = struInput.size();
        String str = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
                "<FaceAppendData>" +
                "<name>test</name>" +
                "<gender>1</gender>" +
                "<bornTime>19900101</bornTime>" +
                "<certificateType>111</certificateType>" +
                "<certificateNumber>123456789012345678</certificateNumber>" +
                "<certificatePicUrl>http://192.168.1.64/certificate.jpg</certificatePicUrl>" +
                "<facePicUrl>http://192.168.1.64/face.jpg</facePicUrl>" +
                "</FaceAppendData>";
        byte[] byInput = str.getBytes();
        struInput.lpRequestUrl = "POST /ISAPI/Intelligent/FDLib/FDSearch/AddFaceDataInFDLib?format=json".getBytes();
        struInput.dwRequestUrlLen = struInput.lpRequestUrl.length;
        struInput.lpInBuffer = byInput;
        struInput.dwInBufferSize = byInput.length;
        struInput.write();
        Pointer lpInBuffer = struInput.getPointer();
        HikvisionLibrary.NET_DVR_XML_CONFIG_OUTPUT struOutput = new HikvisionLibrary.NET_DVR_XML_CONFIG_OUTPUT();
        struOutput.dwSize = struOutput.size();
        struOutput.lpOutBuffer = new byte[1024];
        struOutput.dwOutBufferSize = struOutput.lpOutBuffer.length;
        struOutput.write();
        Pointer lpOutBuffer = struOutput.getPointer();
        boolean result = HikvisionLibrary.INSTANCE.NET_DVR_SendRemoteConfig(lUserID.getValue(), 255, HikvisionLibrary.NET_DVR_SET_FACEAPPEND_DATA, lpInBuffer, struInput.size(), lpOutBuffer, struOutput.size());
        if (!result) {
            System.out.println("添加人脸失败，错误码：" + HikvisionLibrary.INSTANCE.NET_DVR_GetLastError());
        }

        // 注销登录
        HikvisionLibrary.INSTANCE.NET_DVR_Logout_V30(lUserID.getValue());
    }
}

需要注意的是，代码中的IP地址、端口、用户名、密码等信息需要替换为实际的门禁设备信息。同时，需要将海康门禁SDK的库文件 HCNetSDK.dll 放置在Java工程的运行路径下。人脸信息需要按照门禁设备接口要求的XML格式进行组装，并通过海康门禁SDK的接口发送到门禁设备。
