将文件上传到ftp时出错

Question

我想将csv供稿上传到公共ftp。

我有这个：

global $_CONFIG;
$host           = $_CONFIG['po']['ftp']['server'];
$username       = $_CONFIG['po']['ftp']['username'];
$password       = $_CONFIG['po']['ftp']['password'];
$ftp_path       = $_CONFIG['po']['ftp']['upload_path'];

$file = $export_file;
$fp = fopen($export_file, 'r+');

// set up basic connection
$conn_id = ftp_connect($host);

// login with username and password
$login_result = ftp_login($conn_id, $username, $password);

// try to upload $file
if (ftp_fput($conn_id, $ftp_path, $fp, FTP_BINARY)) {
    echo "Successfully uploaded $file\n";
    exit;
} else {
    echo "There was a problem while uploading $file\n";
    exit;
}
// close the connection and the file handler
fclose($fp);

ftp_close($conn_id);

主机，用户，密码正确。 导出文件为D:/some path .csv

问题是ftp服务器上的文件名为.upload.somefile.csv （并且没有完整大小）。

ftp_path是/somefile.csv 。

我究竟做错了什么？

Answer 1

发生这种情况的原因是FTP的工作方式，与您的网络布局冲突。

尽管您连接到FTP服务器来控制会话，但是默认情况下，服务器随后会通过单独的数据连接“回叫”给您进行传输。 在某些情况下，防火墙，NAT等都可能干扰此过程。

尝试使用ftp_pasv来使用FTP的PASV模式，这会反转数据连接的方向。

csv文件应使用FTP_ASCII ，而不是FTP_BINARY

所以：

  global $_CONFIG;
    $host           = $_CONFIG['po']['ftp']['server'];
    $username       = $_CONFIG['po']['ftp']['username'];
    $password       = $_CONFIG['po']['ftp']['password'];
    $ftp_path       = $_CONFIG['po']['ftp']['upload_path'];

        $file = $export_file;
        $fp = fopen($export_file, 'r+');

        // set up basic connection
        $conn_id = ftp_connect($host);

        // login with username and password
        $login_result = ftp_login($conn_id, $username, $password);

        // try to upload $file
        if (ftp_fput($conn_id, $ftp_path, $fp, FTP_ASCII)) {
            echo "Successfully uploaded $file\n";
            exit;
        } else {
            echo "There was a problem while uploading $file\n";
            exit;
        }
        // close the connection and the file handler
        fclose($fp);

        ftp_close($conn_id);
