URL我想下面的代碼:後處理文件使用Java身份驗證
public class URLUploader {
public static void main(String[] args) throws IOException
{
URL url = new URL("http://77.203.65.164:6011");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
String name = "user";
String password = "password";
String authString = name + ":" + password;
System.out.println("auth string: " + authString);
byte[] authEncBytes = Base64.encodeBase64(authString.getBytes());
String authStringEnc = new String(authEncBytes);
System.out.println("Base64 encoded auth string: " + authStringEnc);
conn.setRequestProperty("Authorization", "Basic " + authStringEnc);
OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());
writer.write("/var/www/html/kannel/javacode/13569595024298.xml");
writer.flush();
String line;
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
writer.close();
reader.close();
}
}
但我得到了以下錯誤:
auth string: optiweb:optiweb
Base64 encoded auth string: b3B0aXdlYjpvcHRpd2Vi
Exception in thread "main" java.io.IOException: Server returned HTTP response code: 500 for URL: 77.203.65.164:6011

出了什麼問題?
您確定您收到驗證錯誤嗎?看起來好像你只是直接向遠程服務器寫入文件,但你可能想要將它作爲表單編碼數據發佈。對於初學者,我建議你使用jakarta [http client library](http://hc.apache.org/httpcomponents-client-ga/index.html)來處理這個問題。 – Zeki
