我用多线程抓取网页就出现这个。请问怎么解决了。基本一开线程就无法使用。谢谢

1 抓错了呗，把代码贴一下看看
2 对方发现有扒手，拒绝提供。 类似QQ的图片空间。

3 你测试抓取 sina 的新闻看看。 如果能用，程序就没问题啦！

提示的不是很清楚了吗，联接超时啊，检查你的网络环境。

违法不等于犯罪，但是界限也模糊。

[waterborn]

IO 连不上, 或者超时

[thinkaboutit]

fdfdf

[thinkaboutit]

应该是对方不允许你这样获取他的内容.

[duzhonghua]

不懂,学习

我用了新浪的.试了一下那个HttpClient的演示程序.也还是不成功.

代码如下:

package myhttpclient;

import java.io.IOException;
import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.methods.*;
/**
*最简单的HTTP客户端,用来演示通过GET或者POST方式访问某个页面
*@authorLiudong
*/

public class SimpleClient {
public static void main(String[] args) throws IOException
{
HttpClient client = new HttpClient();
// 设置代理服务器地址和端口

//client.getHostConfiguration().setProxy("proxy_host_addr",proxy_port);
// 使用 GET 方法 ，如果服务器需要通过 HTTPS 连接，那只需要将下面 URL 中的 http 换成 https
HttpMethod method=new GetMethod("http://finance.sina.com.cn/chanjing/b/20080415/07584749699.shtml");
//使用POST方法
//HttpMethod method = new PostMethod("http://java.sun.com");
client.executeMethod(method);

//打印服务器返回的状态
System.out.println(method.getStatusLine());
//打印返回的信息
System.out.println(method.getResponseBodyAsString());
//释放连接
method.releaseConnection();
}
}


异常如下:

你们公司是用代理上网吗？
要是的把代理配好。
client.getHostConfiguration().setProxy("代理的ip地址",代理的端口);
如：client.getHostConfiguration().setProxy("192.168.0.254",80);

我们公司代理上网的程序里不配代理我也连不上，程序里配置了代理才可以。
