以下是利用Java控制海康威视NVR转动摄像头的示例代码:
```java
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Base64;
public class HikvisionCameraController {
private static final String BASE_URL = "http://<NVR_IP_ADDRESS>/";
public static void main(String[] args) {
String username = "<NVR_USERNAME>";
String password = "<NVR_PASSWORD>";
String cameraIndexCode = "<CAMERA_INDEX_CODE>";
int channelNumber = <CHANNEL_NUMBER>;
String url = BASE_URL + "ISAPI/PTZCtrl/channels/" + channelNumber + "/absolute";
String xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><PTZData><pan>" + 10.0 + "</pan><tilt>" + 10.0 + "</tilt><zoom>" + 10.0 + "</zoom></PTZData>";
try {
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
con.setRequestMethod("PUT");
addAuthenticationHeader(con, username, password);
con.setRequestProperty("Content-Type", "application/xml");
con.setRequestProperty("Accept", "application/xml");
con.setDoOutput(true);
con.getOutputStream().write(xml.getBytes("UTF-8"));
int responseCode = con.getResponseCode();
System.out.println("Response Code : " + responseCode);
} catch (Exception e) {
e.printStackTrace();
}
}
private static void addAuthenticationHeader(HttpURLConnection con, String username, String password) {
String authString = username + ":" + password;
String authStringEncoded = Base64.getEncoder().encodeToString(authString.getBytes());
con.setRequestProperty("Authorization", "Basic " + authStringEncoded);
}
}
```
在代码中,您需要替换以下变量的值:
- `<NVR_IP_ADDRESS>`:您的海康威视NVR的IP地址。
- `<NVR_USERNAME>`:您的海康威视NVR的用户名。
- `<NVR_PASSWORD>`:您的海康威视NVR的密码。
- `<CAMERA_INDEX_CODE>`:您要控制的摄像头的索引代码。
- `<CHANNEL_NUMBER>`:与摄像头相关联的通道号。
请注意,此代码仅仅是示例代码,您需要根据实际情况进行修改和调整。同时,您需要确保您已经获得了海康威视NVR的授权,才能使用这段代码进行控制。
