java对接海康门禁ISAPI

对接海康门禁ISAPI可以通过Java的HttpClient来实现。以下是一个简单的示例代码：

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

public class Main {
    public static void main(String[] args) {
        String url = "http://your_door_controller_ip/ISAPI/AccessControl/Status";
        HttpClient httpClient = HttpClients.createDefault();
        HttpGet httpGet = new HttpGet(url);
        httpGet.setHeader("Authorization", "Basic YWRtaW46MTIzNDU2");
        
        try {
            HttpResponse response = httpClient.execute(httpGet);
            int statusCode = response.getStatusLine().getStatusCode();
            if (statusCode == HttpStatus.SC_OK) {
                HttpEntity entity = response.getEntity();                String result = EntityUtils.toString(entity);
                // 处理返回结果
                System.out.println(result);
            } else {
                // 处理请求失败的情况
                System.out.println("请求失败，状态码：" + statusCode);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

请替换`url`和`Authorization`头中的IP地址和凭证信息为实际的门禁控制器IP地址和凭证信息。
