無法使用JCIFS API在Java中

Question

我試圖讀取共享驅動器文件，但我得到一個錯誤

jcifs.smb.SmbException讀取共享驅動器文件：無法連接到服務器 java.net。 UnknownHostException：.. MSBROWSE。 < 01>

我累了幾件事，但似乎沒有任何工作。我將System.out.println（sFile.canRead（））視爲true，這意味着連接成功。

public void readFilefromSharedDrive() throws IOException { 
     String user = "user" + ":" + "pwd"; 
     NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(user); 
     SmbFile sFile = null; 
     try { 
      sFile = new SmbFile("smb:///ip//path//filname.txt", auth); 
      System.out.println(sFile.canRead()); 
      byte[] buffer = new byte[1024]; 
      try (SmbFileInputStream in = new SmbFileInputStream(sFile)) { 
       int bytesRead = 0; 
       do { 
        bytesRead = in.read(buffer); 
        // here you have "bytesRead" in buffer array 
       } while (bytesRead > 0); 

      } catch (Exception e) { 
       JOptionPane.showMessageDialog(null, "ERROR: " + e); 
      } 
     } catch (MalformedURLException e1) { 
      e1.printStackTrace(); 
     } 
    } 

它在SmbFileInputStream拋出錯誤=新SmbFileInputStream（sFile）

這對我的作品

SmbFile smbfile = getSmbFile(newpath, getCredentials(user, password)); 

    public NtlmPasswordAuthentication getCredentials(String usr, String pwd) { 
    NtlmPasswordAuthentication credentials = null; 
    if(usr.length()==0){ 
     credentials = NtlmPasswordAuthentication.ANONYMOUS; 
    }else { 
     credentials = new NtlmPasswordAuthentication(null, usr, 
       pwd); 
    } 
    return credentials; 
}
