问题描述

我正在尝试使用 Apache Commons Net 进行 FTP 文件传输.

I'm trying to use Apache Commons Net for FTP file transfers.

问题是文件间歇性地到达服务器损坏.损坏"是指 WinRAR 告诉我一个 ZIP 文件有一个 意外结束存档".有时文件完全是空的.我注意到大文件 (100kb+) 会发生这种情况，但小文件 (20kb) 也会发生这种情况.

Problem is files are intermittently arriving at the server corrupt. By 'corrupt' I mean that WinRAR tells me a ZIP file has an 'Unexpected end of archive'. Sometimes the files are completely empty. I have noticed that this happens more for larger files (100kb+), however does happen for small files too (20kb).

我知道上传的源 zip 文件是有效的，并且只有 243kb.

I know for a fact that the source zip file being uploaded is valid, and is only 243kb.

我没有从代码中得到任何错误/异常.

I do not get any errors/exceptions from the code.

这是正在执行的代码:

int CON_TIMEOUT = (int) TimeUnit.SECONDS.toMillis(20); // fail if can't connect within 20 seconds
int LIVE_TIMEOUT = (int) TimeUnit.MINUTES.toMillis(5); // allow up to 5 minutes for data transfers

FTPClient client = new FTPClient();
client.setConnectTimeout(CON_TIMEOUT);
client.setDataTimeout(LIVE_TIMEOUT);
client.connect(host);
client.setSoTimeout(LIVE_TIMEOUT);
client.login(user, pass);
client.changeWorkingDirectory(dir);
log("client ready");

File file = new File(filePath);
String name = new Date().getTime() + "-" + file.getName();

InputStream fis = null;
try
{
    fis = new FileInputStream(file);
    if (!client.storeFile(name, fis))
        throw new RuntimeException("store failed");
    log("store " + name + " complete");
}
finally
{
    IOUtils.closeQuietly(fis);
    try
    {
        client.logout();
        log("logout");
    }
    catch (Throwable e)
    {
        log("logout failed", e);
    }
    try
    {
        client.disconnect();
        log("disconnect");
    }
    catch (Throwable e)
    {
        log("disconnect failed", e);
    }
}

还有一些日志:

请注意，所有这些都在 15 秒内完成，并且服务器上的所有生成文件都已损坏.

Note that all of these were complete within 15 seconds, and all of the resulting files on the server are corrupt.

我也进行了测试，没有设置任何超时，问题仍然存在.

I have also tested without setting any timeouts and the problem still occurs.
