Automatically exported from code.google.com/p/ftp4go

This is an FTP client started as a port of the standard Python FTP client library
Forked form code.google.com/p/ftp4go and change some dependenes of the package

Installation

go get github.com/shenshouer/ftp4go

How to use it

Import the library in your code and call the methods exposed by the FTP structure, for instance:

package main  
import (
  "fmt"
  "os"
  ftp4go "github.com/shenshouer/ftp4go"
)  
func main() {
  ftpClient := ftp4go.NewFTP(0) // 1 for debugging
  //set time out
  ftpClient.SetFTPTimeout(20 * time.Second)
  //connect
  _, err := ftpClient.Connect("myFtpAddress", ftp4go.DefaultFtpPort)
  if err != nil {
    fmt.Println("The connection failed")
    os.Exit(1)
  }   
  defer ftpClient.Quit()
  _, err = ftpClient.Login("myUsername", "myPassword", "")
  if err != nil {
    fmt.Println("The login failed")
    os.Exit(1)
  }      
  //Print the current working directory
  var cwd string
  cwd, err = ftpClient.Pwd()
  if err != nil {
    fmt.Println("The Pwd command failed")
    os.Exit(1)
  }
  fmt.Println("The current folder is", cwd)
}

	defer ftpClient.Quit()

	_, err = ftpClient.Login("bob", "p@ssw0rd", "")
	if err != nil {
		fmt.Println("The login failed")
		os.Exit(1)
	}

	//Print the current working directory
	var cwd string
	cwd, err = ftpClient.Pwd()
	if err != nil {
		fmt.Println("The Pwd command failed")
		os.Exit(1)
	}
	fmt.Println("The current folder is", cwd)


	// get the remote file size
	size, err := ftpClient.Size("/home/bob/"+downloadFileName)
	if err != nil {
		fmt.Println("The Pwd command failed")
		os.Exit(1)
	}
	fmt.Println("size ", size)

	// start resume file download
	if err = ftpClient.DownloadResumeFile("/home/bob/"+downloadFileName, "/Users/goyoo/ftptest/"+downloadFileName, false); err != nil{
		panic(err)
	}

}

More on the code

Being a port of a Python library, the original Python version is probably the best reference.
Python ftplib

Differences to the original version

Some new methods have been implemented to upload and download files, recursively in a folder as well.

TODOs and unsupported functionality

• TLS is not supported yet
• add multi goroutine for one download task support
