ftp-client-php（FTP client PHP 运维）

FTP Client (PHP Proxy)

Full-featured FTP/FTPS client skill for OpenClaw. Routes all FTP operations through an HTTP PHP proxy server, so it works even when direct FTP connections are blocked (e.g. HuggingFace Spaces, serverless environments). Click to deploy ftp-php-proxy.

Architecture

OpenClaw ──HTTP──▶ PHP Proxy Server (api.php) ──FTP──▶ FTP Server

Environment Variable

Set FTP_PHP_CONFIG in the OpenClaw skill management panel. JSON format:

{"ftp_php_domain":"https://your-server.com/api.php","ftp_php_apikey":"","ftp_client_host":"ftp.example.com","ftp_client_port":"21","ftp_client_username":"user","ftp_client_password":"pass","ftp_client_connect_mode":"passive","ftp_client_protocol":"ftps","ftp_client_encrypt_mode":"explicit"}

Field definitions:

• ftp_php_domain (required): Full URL of the PHP proxy api.php endpoint
• ftp_php_apikey (optional): API key for the PHP proxy, empty string = no auth
• ftp_client_host (required): FTP server hostname
• ftp_client_port (optional): FTP server port, default 21
• ftp_client_username (required): FTP login username
• ftp_client_password (required): FTP login password
• ftp_client_connect_mode (optional): active or passive, default passive
• ftp_client_protocol (optional): ftp or ftps, default ftp
• ftp_client_encrypt_mode (optional): explicit or implicit, only meaningful when protocol is ftps

Example (alwaysdata FTPS):

{"ftp_php_domain":"https://your-server.com/api.php","ftp_php_apikey":"","ftp_client_host":"ftp.example.com","ftp_client_port":"21","ftp_client_username":"user","ftp_client_password":"pass","ftp_client_connect_mode":"passive","ftp_client_protocol":"ftps","ftp_client_encrypt_mode":"explicit"}

Notes

• All FTP operations are proxied through your PHP server via HTTP.
• Upload works by sending file as base64 to the PHP proxy.
• Download retrieves base64 content from the PHP proxy and saves locally.
• Large files are supported but limited by PHP server's upload_max_filesize and memory_limit.
• Set FTP_PHP_CONFIG env var as a single-line JSON string.
