The proxy string is a proxy format that combines the host, port, username and password into one line, and is suitable for batch copying to third-party tools.

Common format

username:password@host:port

When to use one-line format

• The tool only has one proxy input box.
• Import proxy list in batches.
• The script reads a line of proxy configuration.

When to fill in

• in separate columns? The tool provides four input boxes for host, port, username, and password.
• Different fields need to be saved separately.
• Easier to check each parameter when troubleshooting connection issues.

Common errors

• Written in reverse order.
• Missing port.
• Excessive spaces or line breaks were copied.
• Treat the background login password as the proxy password.
