带有FTP登录错误的HTTPS客户端:javax.net.ssl.SSLException:502 SSLv23/TLSv1 java [英] HTTPS Client with FTP Login Error: javax.net.ssl.SSLException: 502 SSLv23/TLSv1 java

问题描述

我对Java来说还很陌生，所以您向我解释的越多，学到的知识就越多，我将问的问题也就越少；)我正在尝试对客户端进行编程以使其连接到ftp.availity.com，但我无法终生让客户端登录.我尝试更改端口号(443、20等)，但它们都未在控制台日志中返回响应，并且仅返回超时错误.我唯一可以执行操作的端口是端口21.我知道这是FTP，并且我认为这可能是错误的来源，但是我不知道如何纠正它，因为显然更改端口#不能纠正错误.问题.任何帮助，将不胜感激！

I am pretty new to Java so the more you explain the more I learn, and less questions I will ask ;) I am trying to program a client to connect to ftp.availity.com but I cannot for the life of me get the client to login. I have tried changing the port numbers (443, 20, etc) but they all do not return a response in the console log and it only returns a timeout error. The only one I can get some action with is port 21. I know this is FTP and I think that may be where there error is coming from but I have no idea how to correct it because obviously changing the port # doesn't correct the issue. Any help would be appreciated!

这是我的代码:

import java.io.IOException;
import org.apache.commons.net.ftp.*;

public class FTPApp {
private static void showServerReply(FTPSClient ftpClient) {
    String[] replies = ftpClient.getReplyStrings();
    if (replies != null && replies.length > 0) {
        for (String aReply : replies) {
            System.out.println("SERVER: " + aReply);
        }
    }
}

public static void main(String[] args) {

    String server = "ftp.availity.com";
    int port = 21;
    String user = "user";
    String pass = "pass";
    FTPSClient ftpClient = new FTPSClient();

    try {
        ftpClient.connect( server, port);   
        showServerReply(ftpClient);
        int replyCode = ftpClient.getReplyCode();
        if (!FTPReply.isPositiveCompletion(replyCode)) {
            System.out.println("Operation failed. Server reply code: " + replyCode);
            return;
        }
        boolean success = ftpClient.login(user, pass);
        showServerReply(ftpClient);
        if (!success) {
            System.out.println("Could not login to the server");
            return;
        } else {
            System.out.println("LOGGED IN SERVER");
        }
    } catch (IOException ex) {
        System.out.println("Oops! Something wrong happened");
        ex.printStackTrace();
    }
}

}

这是错误:

Oops! Something wrong happened

推荐答案

我发现了！

ftp.availity.com是我要登录的URL，但是当将其放入主机时，为了使其安全，我要做的就是保留"FTPSClient"，但将主机设置为" ftps .availity.com"，而不仅仅是"ftp.availity.com".

the ftp.availity.com was the url I would go to to login but when putting it in for the host, to make it secure, all I had to do was keep the "FTPSClient" but make the host "ftps.availity.com" not just "ftp.availity.com".

ftp服务器是在Axway SecureTransport或Tumbleweed下设置的，因此希望有相同问题的任何人都可以找到此线程！！！

The ftp server is setup under Axway SecureTransport or Tumbleweed so hopefully anyone with the same issue can find this thread!!!

非常感谢您对我的帮助！
