java 京东云打印对接代码

对接京东云打印需要编写Java代码，并使用京东云打印的API进行调用。以下是一个简单的示例代码：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;

public class JDCloudPrintIntegration {
    public static void main(String[] args) {
        try {
            // 准备请求的URL和参数
            String url = "https://api.jdcloud.com/v1/print/tasks";
            String requestData = "{\"printerId\":\"your_printer_id\",\"content\":\"your_print_content\"}";

            // 创建URL对象并打开连接
            URL obj = new URL(url);
            HttpURLConnection connection = (HttpURLConnection) obj.openConnection();

            // 设置请求方法为POST
            connection.setRequestMethod("POST");

            // 设置请求头
            connection.setRequestProperty("accept", "application/json");
            connection.setRequestProperty("content-type", "application/json");
            connection.setRequestProperty("authorization", "your_authorization_token");

            // 开始写入请求数据
            connection.setDoOutput(true);
            OutputStream os = connection.getOutputStream();
            os.write(requestData.getBytes());
            os.flush();
            os.close();

            // 获取响应结果
            BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String inputLine;
            StringBuffer response = new StringBuffer();
            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }
            in.close();

            // 输出响应结果
            System.out.println(response.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

以上代码中，需要将`your_printer_id`替换为你的打印机ID，`your_print_content`替换为需要打印的内容，`your_authorization_token`替换为你的授权令牌。通过调用京东云打印的API，可以实现与京东云打印的对接。
