java下获取图片宽高总是等于0的问题，但是把生成的url输入到浏览器中能正确显示图片信息

Question

url=“http://smartcloset1.qiniudn.com/Item_Useradd_29B9C16C-543C-4DAC-8420-2F355DEADD3B?imageInfo&e=1416057339&token=J-crNw5p5Xy0pafT0HBOZwvz0FyFwyTQ6SwhcsPc:Ti3pmfHQkETlrDN9dV6cXj-ZblY=”;
url输入浏览器能出现上面的结果。但是ret.height和ret.width总是0，为什么呢？
ImageInfoRet ret = ImageInfo.call(url);
int height=0,width=0;

            if(ret.ok()){
                height=ret.height;
                width=ret.width;
            }

完全可以返回。

package qiniu.demo;

import com.qiniu.api.auth.digest.Mac;
import com.qiniu.api.config.Config;
import com.qiniu.api.fop.ImageInfo;
import com.qiniu.api.fop.ImageInfoRet;
import com.qiniu.api.rs.GetPolicy;
import com.qiniu.api.rs.PutPolicy;
import com.qiniu.api.rs.URLUtils;

public class imageInfo {

    public static void main(String[] args) throws Exception {
        Config.ACCESS_KEY = "...";
        Config.SECRET_KEY = "...";
        Mac mac = new Mac(Config.ACCESS_KEY, Config.SECRET_KEY);

        String baseUrl = URLUtils.makeBaseUrl("smartcloset1.qiniudn.com", "Item_Useradd_29B9C16C-543C-4DAC-8420-2F355DEADD3B");
        GetPolicy getPolicy = new GetPolicy();


        ImageInfo imageinfo = new ImageInfo();

        ImageInfoRet ret = imageinfo.call( "http://smartcloset1.qiniudn.com/Item_Useradd_29B9C16C-543C-4DAC-8420-2F355DEADD3B", mac) ;
        System.out.println(ret.getResponse() + ret.getStatusCode() );
    }
}
