javaeye网页上的图片用java下载不下来

Question

用到了iText-2.0.8.jar
这个jar包
如果没有这个jar包，附件提供下载，问题是用最基础的
java.io.FileOutputStream;
java.io.InputStream;
java.net.URL;
java.net.URLConnection;
这四个类也下载不下来啊
请高手指正

Answer 1

iteye 有拦截爬虫的功能。 需要做更深的设置和配置

Answer 2

谢谢提醒，这样就可以了呵呵url=new URL(url2);
imgfileName=url2.split("/")[url2.split("/").length-1];
 HttpURLConnection connection = (HttpURLConnection) url.
                openConnection();
connection.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)"); 
connection= url.openConnection();
inStream = connection.getInputStream();
fs = new FileOutputStream(imgsavePath+imgfileName);
buffer = new byte[1204];
while ((byteread = inStream.read(buffer)) != -1) {
                fs.write(buffer, 0, byteread);
            }
