java上传图片到七牛

Question

小白想用安卓上传图片到七牛，先用java试了下，但一直抛出异常，下面是我代码，后面给出异常信息

import java.awt.image.BufferedImage;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;

import com.qiniu.common.QiniuException;
import com.qiniu.http.Response;
import com.qiniu.storage.UploadManager;
import com.qiniu.util.Auth;

public class TestQiniu {
    
    public static void main(String[] args) {
        String uptoken=getUptoken();
        System.out.println(uptoken);
        BufferedImage bufferedImage = null;
        try {
            bufferedImage = ImageIO.read(new File("test.png"));
        } catch (IOException e) {
            e.printStackTrace();
        }
        ByteArrayOutputStream baos=new ByteArrayOutputStream();
        try {
            ImageIO.write(bufferedImage, "png", baos);
        } catch (IOException e) {
            e.printStackTrace();
        }
        new TestQiniu().upLoadPic(baos.toByteArray(), "test1", uptoken);
        
    }
    
    private static String getUptoken() {
        Auth auth = Auth.create("8EqgYr4A18xyeUzWdDHt6OKTKJ5wW9mttLKiobF_",
                "gFxrGJAGII497kyncBlZ7_V1GMEgqRW00ytXxg8q");
        String uptoken = auth.uploadToken("agriculturetest","test_pic",3600,null);
        return uptoken;
    }
    
    public void upLoadPic(byte[] data,String key,String token){
        UploadManager uploadManager=new UploadManager();
        try {
            Response response= uploadManager.put(data, key, token);
            System.out.println(response.isOK());
        } catch (QiniuException e) {
            e.printStackTrace();
        }
        
        
    }
}

之前有帖子说是java-sdk 上传超时可能是由于 okhttp,okio 的版本问题引起，更换 okhttp 2.3 okio 1.6试下

我换了试过，也没用，还是同一个错，文档看了又看实在找不到问题，求解答。谢谢

更新okhttp到2.7.1

qiniusdk 7.0.8使用了新版的okhttp
