HTTP错误407需要代理身份验证

Question

我试图通过使用此代码访问该URL

System.setProperty("http.proxyHost", "111.88.15.108");
    System.setProperty("http.proxyPort", "8002");
    System.setProperty("http.proxyUser", "user");
    System.setProperty("http.proxyPassword", "password");
    URL oracle = new URL("http://www.google.com/");
    URLConnection yc = oracle.openConnection();
    BufferedReader in = new BufferedReader(new InputStreamReader(
            yc.getInputStream()));
    String inputLine;
    while ((inputLine = in.readLine()) != null)

        System.out.println(inputLine);
    in.close();

这在我的窗口机器上工作正常,但这在linux机器上不起作用.我这样变得很恐怖

线程"main"中的异常java.io.IOException:服务器返回HTTP响应代码:407为URL:http://www.google.com/ at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source)在com.yahoo.Connection.main(Connection.java:31)

即使代理设置是正确的,我也尝试过

java -Dhttp.proxyHost="111.88.15.108" -Dhttp.proxyPort="8002" -Dhttp.proxyUser="user" -Dhttp.proxyPassword="password"  -jar yahoo_test3.jar

但相同的错误,我试图在/ etc/profile中设置导出http_proxy =但没有用

知道哪里出错了.

我有同样的问题.以下对我有用.

Authenticator.setDefault(new Authenticator() 
{
    protected PasswordAuthentication getPasswordAuthentication() 
    {
    return new PasswordAuthentication("username","password".toCharArray());
    }
});
