尝试在PHP中使用SFTP导致500错误

已采纳

I've tried several different methods of connecting to an SFTP server and in all cases I get a 500 error either when I connect or when I try to upload a file.

I've tried connecting to two different servers, getting the same results each time. I am however able to connect to both servers using a GUI interface client, no problem.

Using SSH2_connect:

//<!--************************************************************************-->
//<!--*** Connect using ssh2
//<!--************************************************************************-->

$conn = ssh2_connect($ftp_host, 22);
ssh2_auth_password($conn, $ftp_username, $ftp_password);

//<!--************************************************************************-->
//<!--*** Send the file
//<!--************************************************************************-->

ssh2_scp_send($conn, $localfile, $remote_file);

The connect call causes a 500 error.

I also tried using PHPSecLib, as recommended by so many people on StackExchange, but I run into the same problem.

include("common/PHP SFTP/Net/SFTP.php");

//<!--************************************************************************-->
//<!--*** Connect using sftp
//<!--************************************************************************-->

$sftp = new Net_SFTP($ftp_host);

//<!--************************************************************************-->
//<!--*** Log into ftp server
//<!--************************************************************************-->

if ($sftp->login($ftp_username, $ftp_password)) {

  //<!--************************************************************************-->
  //<!--*** Send local file via ftp
  //<!--************************************************************************-->

  if(!$sftp->put($remote_file, $localfile)){
     errorLog(1,"DEBUG","eft transfer","Fail");
  }

}else{
  errorLog(1,"DEBUG","sftp connection","Fail");
}

//<!--************************************************************************-->
//<!--*** Close the connection
//<!--************************************************************************-->

ftp_close($ftp_connection);

In this case creating a new Net_SFTP object causes no problems so it's not a pathing issue to the included PHPSecLib file, but as soon as I try to login to the ftp server it falls over with a 500 error.

Using phpinfo() I've confirmed that I have OpenSSL enabled on the server. SFTP protocol is also enabled. SSH2 DLL is also installed and enabled.

I don't know what else to look for.

These are the errors in my log file

    Turns out the phpseclib code was unable to find the following files:

    Math/BigInteger.php
    Crypt/Random.php
    Crypt/Hash.php
    Crypt/Base.php
    

    ...because the script relies on the php include path which by default is c:\php\pear.

    So I solved it by adding the following two lines to the top of my script.

    $currentdirectory = getcwd();
    set_include_path(get_include_path().";".$currentdirectory.'/common/PHP SFTP');
