备注：我创建ftp用户文件的方式跟课程中的不一样，是以下面的方式创建的
How To Set Up vsftpd for a User’s Directory on Ubuntu 18.04
并且我用终端ftp命令上传文件没有问题（只是需要进入下一级目录files/ , 默认进入的目录是没有写权限的）

调试：

1. 我加了一行logger
   
   日志文件：
   
   这就说明就是图片中最后一行代码的问题！

我的ftp用户和文件夹是这样创建了：
用户：useadd sammy -d /product/sammy/ftpfile/ -s /usr/sbin
ftpfile: 没有写权限 chmod a-w ftpfile/
files: 在ftpfile/ 下创建子目录 files ，并改变用户（组） chown -R sammy:sammy files/
每次上传文件，登录之后需要进入 files 文件夹才可以进行上传操作

注意：之前的我发的评论的方法和方向都是错误的，之所以无法上传文件是因为 云服务器和阿里云安全组没有开放 pasv 的 61001/62000 的端口范围

时至今日，耗时两天，终于完美解决了！！

方向是星辰大海～

Answer 2

提问者 williamdsy 2020-04-27 12:39:20

upload.do 终于返回了200！！！

我把这些都注释了(事实上只需要注释掉ftpClient.enterLocalPassiveMode();
就可以了)，完全模拟了我在终端连接 ftp 的操作！！！

这个问题已经解决

开启新征程！！！！

方向是星辰大海～

Answer 3

提问者 williamdsy 2020-04-27 07:51:18

就是在这里，但我找不到问题所在，代码没有错

Answer 4

提问者 williamdsy 2020-04-27 05:35:08

与我推测一致，但应该怎么改呢？remotePath 我试过了 img 和 /product/sammy/ftpfile/img,但是都没用

Answer 5

提问者 williamdsy 2020-04-27 01:54:31

我想问题还是想岔了，既然我能够在终端连接 ftp 并成功上传文件，代码也不会有问题，

那问题就是 两者之间的配合问题，我应该修改的是代码里面 连接 ftp 的操作！

但是应该怎么改呢？

明天再来吧，先睡了

Geely 大哥救我！

Answer 7

提问者 williamdsy 2020-04-26 23:42:02

这就陷入了一个很尴尬的境地了：ftpClient.changeWorkingDirectory(remotePath); 没办法成功，但是不改变目录的话又没有写权限

Answer 8

提问者 williamdsy 2020-04-26 23:33:19

我知道了 因为 ftpfile/ 是不能有写权限的，所以这行代码就会导致错误了

我可能需要改变这个目录

Answer 9

提问者 williamdsy 2020-04-26 23:23:40

现在我要：

1. 按照课程中的方式创建ftp用户和文件夹

2. 如果第一步还不行，就只能把 vsftpd 配置文件也换成课程中的

3. 顾虑就是，以前已经试过了课程中的方法，总是无法登录

4. 看来我得继续研究 vsftpd 的本质

提问者 williamdsy 2020-04-26 21:31:18

突然看到 配置文件最后一行 

要不取消掉它的注释试试？

不管了，先打王者

• 提问者 williamdsy #1

  很遗憾，取消这行注释没有用

• 提问者 williamdsy #2

  难道是因为输入流的问题？

• 提问者 williamdsy #3

  不应该的，因为，我这个代码是从码云上下载的
  所以问题还是出再云服务器上

vsftpd 的配置文件如下：

# Example config file /etc/vsftpd.conf # # The default compiled in settings are fairly paranoid. This sample file # loosens things up a bit, to make the ftp daemon more usable. # Please see vsftpd.conf.5 for all compiled in defaults. # # READ THIS: This example file is NOT an exhaustive list of vsftpd options. # Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's # capabilities. # # # Run standalone?  vsftpd can run either from an inetd or as a standalone # daemon started from an initscript. listen=NO # # This directive enables listening on IPv6 sockets. By default, listening # on the IPv6 "any" address (::) will accept connections from both IPv6 # and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6 # sockets. If you want that (perhaps because you want to listen on specific # addresses) then you must run two copies of vsftpd with two configuration # files. listen_ipv6=YES # # Allow anonymous FTP? (Disabled by default). anonymous_enable=NO # # Uncomment this to allow local users to log in. local_enable=YES # # Uncomment this to enable any form of FTP write command. write_enable=YES # # Default umask for local users is 077. You may wish to change this to 022, # if your users expect that (022 is used by most other ftpd's) #local_umask=022 # # Uncomment this to allow the anonymous FTP user to upload files. This only # has an effect if the above global write enable is activated. Also, you will # obviously need to create a directory writable by the FTP user. #anon_upload_enable=YES # # Uncomment this if you want the anonymous FTP user to be able to create # new directories. #anon_mkdir_write_enable=YES # # Activate directory messages - messages given to remote users when they # go into a certain directory. dirmessage_enable=YES # # If enabled, vsftpd will display directory listings with the time # in  your  local  time  zone.  The default is to display GMT.

提问者 williamdsy 2020-04-26 21:24:54

但是为什么会有这个问题呢？

应该就是上面所说的 配置文件和代码中 ftpClient 的设置问题；

那么应该是修改 vsftpd 配置文件还是 代码中的 ftpClient 的属性呢？

• 提问者 williamdsy #1

  首先，我要比较一下 vsftpd 配置文件中的额属性 和 ftpClient 的属性，看一下他们有什么联系

  如果有大哥知道怎么办，请教我一下哈哈哈

Answer 13

提问者 williamdsy 2020-04-26 21:08:41

应该就是这里出了问题，可能是因为跟我的vsftpd的配置文件冲突了，我调试一下
