How to SFTP upload files from PHP
提问by John
I'm having trouble using PHP to SFTP upload files to a remote server. When I use cURL, I'm getting the error described here:
我在使用 PHP 将文件通过 SFTP 上传到远程服务器时遇到问题。当我使用 cURL 时，我收到了这里描述的错误：
SFTP from PHP - undefined constant CURLOPT_PROTOCOLS and CURLPROTO_SFTP?
来自 PHP 的 SFTP - 未定义的常量 CURLOPT_PROTOCOLS 和 CURLPROTO_SFTP？
I also tried phpseclib as suggested in:
我还按照以下建议尝试了 phpseclib：
But when i try phpseclib, i get these errors:
但是当我尝试 phpseclib 时，我收到了这些错误：
Warning: require_once(Math/BigInteger.php) [function.require-once]: failed to open stream: No such file or directory in /home/john/public_html/test/Net/SSH2.php on line 53
Fatal error: require_once() [function.require]: Failed opening required 'Math/BigInteger.php' (include_path='.:/usr/share/php:/usr/share/pear') in /home/john/public_html/test/Net/SSH2.php on line 53
I then tried using system commands in php like so, but nothing happened:
然后我尝试像这样在 php 中使用系统命令，但什么也没发生：
<?php
echo system('sftp [email protected]');
echo system('password');
echo system('put file.csv');
?>
I also tried
我也试过
<?php
$connection = ssh2_connect('shell.example.com', 22);
ssh2_auth_password($connection, 'username', 'password');
ssh2_scp_send($connection, '/local/filename', '/remote/filename', 0644);
?>
but my php server says ss2_connect is not defined.
但是我的 php 服务器说 ss2_connect 没有定义。
I tried to do the following from terminal
我尝试从终端执行以下操作
scp file.csv [email protected]
password
But the server does not allow scp command. I do not have shell access to create ssh keys.
但是服务器不允许 scp 命令。我没有创建 ssh 密钥的 shell 访问权限。
All i can do right now is sftp from terminal and manually upload. But I really want to automate this so a PHP website can do all this.
我现在能做的就是从终端 sftp 并手动上传。但我真的很想自动化这个，这样一个 PHP 网站就可以做到这一切。
There aren't many tutorials on how to SFTP upload from PHP. Is it because it's a bad thing to do? If so, what should I be doing? The server I want to upload to only allows sftp connections.
关于如何从 PHP 进行 SFTP 上传的教程并不多。是因为这样做不好吗？如果是这样，我该怎么办？我想上传到的服务器只允许 sftp 连接。

Per that, phpseclib's root directory needs to be in your include_path. From that page:
为此，phpseclib 的根目录需要在你的 include_path 中。从该页面：
<?php
set_include_path(get_include_path() . PATH_SEPARATOR . 'phpseclib');
include('Net/SFTP.php');
?>
You should really familiarize yourself with this kind of include technique - it's pretty standard for PEAR libraries and Zend ones.
您应该真正熟悉这种包含技术——它是 PEAR 库和 Zend 库的标准。

For this error, you should install ssh2 extension on your server's php.
对于此错误，您应该在服务器的 php 上安装 ssh2 扩展。

You can use Pure-PHP implementation of SSHv2 library.
您可以使用 SSHv2 库的纯 PHP 实现。
Here are some examples of how to use this library:
以下是如何使用此库的一些示例：
<?php
include 'vendor/autoload.php';
$ssh = new \phpseclib\Net\SSH2('www.domain.tld');
if (!$ssh->login('username', 'password')) {
exit('Login Failed');
}
echo $ssh->exec('pwd');
echo $ssh->exec('ls -la');
?>
And:
和：
<?php
include 'vendor/autoload.php';
$key = new \phpseclib\Crypt\RSA();
//$key->setPassword('whatever');
$key->loadKey(file_get_contents('privatekey'));
$ssh = new \phpseclib\Net\SSH2('www.domain.tld');
if (!$ssh->login('username', $key)) {
exit('Login Failed');
}
echo $ssh->read('username@username:~$');
$ssh->write("ls -la\n");
?>

Use the built in SSH library. Using the scp function will be easier than initiating a sftp session too.
使用内置的 SSH 库。使用 scp 功能也比启动 sftp 会话更容易。

To use systemcommand you have to:
要使用system命令，您必须：
- Configure password-less ssh
- Run command like
scp filename1 userid@hostname:filename2, checkman scp. You can do the same withsftpbut with some other options
- 配置无密码 ssh
- 像这样运行命令
scp filename1 userid@hostname:filename2，检查man scp。您可以sftp使用其他选项执行相同操作
