我想下载一个html页面" http://www.slrclub.com/bbs/zboard.php?id=theme_gallery&category=6"
但它需要登录信息
我的代码附在下面
URL url = new URL("http://www.slrclub.com/bbs/zboard.php?id=theme_gallery&category=6");
URLConnection connection = url.openConnection();
connection.setRequestProperty("Referer", "http://www.slrclub.com/");
String name = "myid";
String password = "mypass";
String authString = name + ":" + password;
System.out.println("auth string: " + authString);
byte[] authEncBytes = Base64.encodeBase64(authString.getBytes());
String authStringEnc = new String(authEncBytes);
String basicAuth = "Basic " + javax.xml.bind.DatatypeConverter.printBase64Binary(authString.getBytes());
connection.setRequestProperty ("Authorization", basicAuth);
connection.setConnectTimeout(30000);
InputStream is_img = connection.getInputStream();
OutputStream os_img = new BufferedOutputStream(new FileOutputStream( "1.html"));
for (int b; (b = is_img.read()) != -1;) {
os_img.write(b);
}
os_img.close();
is_img.close();
但它无效
我该怎么办?

此问题与“HTTP授权”
无关www.slrclub.com没有使用HTTP授权。
