通过 ftps 连接 alfresco 的 Java 代码

Question

您好，我正在尝试通过 FTP 连接我们的露天场所，但我收到错误 Unknownhostexception

我的代码如下

public void FTPTest()throws SocketException, IOException
{

    FTPClient ftp = new FTPClient();
    System.out.println("1");
      ftp.connect("172.17.178.144:2121"); // or "localhost" in your case
      System.out.println("2");
      System.out.println("login: "+ftp.login("admin", "admin"));
      System.out.println("3");
      ftp.changeWorkingDirectory("folder/subfolder/");
      // list the files of the current directory
      FTPFile[] files = ftp.listFiles();  
      System.out.println("Listed "+files.length+" files.");
      for(FTPFile file : files) {
       System.out.println(file.getName());
      }
       // lets pretend there is a JPEG image in the present folder that we want to copy to the desktop (on a windows machine)
      ftp.setFileType(FTPClient.BINARY_FILE_TYPE); // don't forget to change to binary mode! or you will have a scrambled image!
            FileOutputStream br = new FileOutputStream("C:\\Documents and Settings\\casonkl\\Desktop\\my_downloaded_image_new_name.jpg");

      ftp.retrieveFile("name_of_image_on_server.jpg", br);
      ftp.disconnect();

     }

我收到以下错误

java.net.UnknownHostException: 172.17.178.144:2121

您应该尝试这样，将端口设置为单独的参数。

FTPClient ftp = new FTPClient();
ftp.connect("172.17.178.144","2121");
ftpClient.connect(server, port);
