問題描述

當(dāng)我嘗試使用 Apache Commons FTPClient 上傳一個簡單的文本文件時:

When I try to upload a simple text file with the Apache Commons FTPClient and this code:

FTPClient ftp = new FTPClient();
int reply;

// connect
try {

    ftp.connect(serverAdd);
    ftp.login(username,password);
    reply = ftp.getReplyCode();

    if(FTPReply.isPositiveCompletion(reply)){
        System.out.println("Connected Success..");

        // upload file
        try {
            String fileDir = "testfile.txt";
            FileInputStream in = null;         
            in = new FileInputStream(fileDir);       
            ftp.storeFile(fileDir,in);
            System.out.println("File upload complete..");
        }catch(IOException e){
            System.out.println(e);
        }

        ftp.disconnect();
        System.out.println("Disconnected..");

    }else {
        System.out.println("Connection Failed..");
        ftp.disconnect();
    }    

} catch (SocketException ex) {
    ex.printStackTrace();
} catch (IOException ex) {
    ex.printStackTrace();
}

在 FTP 服務(wù)器的根目錄中創(chuàng)建了一個文件，但它是空的.怎么了?上傳 PDF 文件時，我已經(jīng)嘗試將 ftp 模式更改為 BINARY.但文件大小也是 0.

A file gets created in the root of the FTP server but it is empty. What's wrong? I already tried to change the ftp mode to BINARY when uploading a PDF file. But the file is also 0 in size.

ftp.setFileType(FTP.BINARY_FILE_TYPE);

我也只想上傳一堆txt文件，所以默認ascii模式應(yīng)該沒問題吧?

I also only want to upload a bunch of txt files, so the default ascii mode should be fine, right?

推薦答案

好吧，看來是我的防火墻問題了.當(dāng)我停用防火墻時，文件會毫無問題地寫入 ftp.

ok, it seems that it is a probem with my firewall. when I deactivate the firewall the file gets written to the ftp with no problem.
