go-universal-network-adapter

go-universal-network-adapter is a Go library for managing file downloads using different network protocols. It does a good job helping you build applications, in which remote files are being browsed, downloaded and processed. Universal Network Adapter offers an elegant abstraction over major network protocols and as such, it could be easily extended or just plugged into your project.

Install

go get -u github.com/goodsru/go-universal-network-adapter

Features

• compatible with http/https/ftp/ftps/sftp - most popular protocols to work with file servers
• tls support - allows connect to server with certificate (not only basic login/password)

Examples

See examples for a variety of examples.

Http:

package main

import (
	"fmt"
	"github.com/goodsru/go-universal-network-adapter/models"
	"github.com/goodsru/go-universal-network-adapter/services"
	"io/ioutil"
	"time"
)

func main() {
    adapter := services.NewUniversalNetworkAdapter()
    remoteFile, err := models.NewRemoteFile(models.NewDestination("http://lorempixel.com/400/200/", nil, nil))
    if err != nil {
        panic(err)
    }
    content, err := adapter.Download(remoteFile)
    if err != nil {
        panic(err)
    }
    
    fmt.Println(content.Name)
    fmt.Println(content.Path)
    buf, err := ioutil.ReadAll(content.Blob)
    fmt.Println(len(buf))
}

Ftp:

In case you don't have production ftp server, then for testing ftp downloading first you need to up ftp server on localhost, as it's implemented in this example.

package main

import (
	"fmt"
	"github.com/goodsru/go-universal-network-adapter/models"
	"github.com/goodsru/go-universal-network-adapter/services"
	"io/ioutil"
)

func main() {
	adapter := services.NewUniversalNetworkAdapter()

	remoteFile, err := models.NewRemoteFile(models.NewDestination("ftp://localhost:21/test1.txt", &models.Credentials{
		User:     "user",
		Password: "pass",
	}, nil))

	if err != nil {
		panic(err)
	}
	content, err := adapter.Download(remoteFile)
	if err != nil {
		panic(err)
	}

	fmt.Println(content.Name)
	fmt.Println(content.Path)
	buf, err := ioutil.ReadAll(content.Blob)
	fmt.Println(string(buf))
}

Sftp:

In case you don't have some production sftp server, then for testing sftp downloading first you need to up sftp server on localhost, as it's implemented in this example.

package main

import (
	"fmt"
	"io/ioutil"
	"github.com/goodsru/go-universal-network-adapter/models"
	"github.com/goodsru/go-universal-network-adapter/services"
)

func main() {
	adapter := services.NewUniversalNetworkAdapter()

	remoteFile, err := models.NewRemoteFile(models.NewDestination("sftp://host.com:22/folder/file.json", &models.Credentials{
		User:     "Admin",
		Password: "Qwerty",
	}, nil))

	if err != nil {
		panic(err)
	}
	content, err := adapter.Download(remoteFile)
	if err != nil {
		panic(err)
	}

	fmt.Println(content.Name)
	fmt.Println(content.Path)
	buf, err := ioutil.ReadAll(content.Blob)
	fmt.Println(string(buf))
}
