从服务器上传文件时出现错误文件号套接字异常
我正在尝试将文件从 android sdcard 上传到 FTP Web 服务器。为此,我使用 Apache FTPClient 库。 这是我上传文件的代码...
FTPClient con = new FTPClient();
try
{
con.connect("host ip",21);
int reply = con.getReplyCode();
if (!FTPReply.isPositiveCompletion(reply))
{
con.disconnect();
System.err.println("FTP server refused connection.");
System.exit(1);
}else{
System.err.println("FTP server connected");
}
if (con.login("username", "password"))
{
con.enterLocalPassiveMode(); // important!
FileInputStream in = new FileInputStream("/mnt/sdcard/xmls/" + fileName);
boolean result = con.storeFile("/"+filename, in);
if (result){
Toast.makeText(DisplaySDCardContent.this, "File Uploaded Successfully.", Toast.LENGTH_LONG).show();
Log.v("upload result", "succeeded");
}
in.close();
}
}
在尝试上传文件时...我收到异常,提示文件号错误..套接字异常...

尝试获取 Apache FTPClient 3.0.1。 3.0好像有bug。
https://repository.apache。 org/content/repositories/snapshots/commons-net/commons-net/3.0.1-SNAPSHOT/
干杯,
Try getting the Apache FTPClient 3.0.1. It seems like there was bug in the 3.0.

Cheers,
确保您在 Android Manifest 中拥有正确的权限:
确认服务器 IP 正确并且另一端存在侦听套接字。你有“主机IP”,但我假设它混淆了你的实际服务器IP。确保您可以从手机以外的其他设备连接到该计算机。
Make sure you have the correct permissions in your Android Manifest:
Confirm that the server IP is correct and that a listening socket exists on the other end. You have "host ip" but I am assuming that is obfuscating your actual server IP. Make sure you can connect to that machine from something other than your phone.
