GoVersion GoDoc License Report

go-box is a Go client library for accessing the Box.com API.

Installation

go get github.com/gildas/go-box

Usage

After importing the package in your code:

import "github.com/gildas/go-box"

You can create a new client with:

client := box.NewClient(context)
Authentication

To let the client authenticate with nox.com, you need to provide credentials and authenticate:

client := box.NewClient(context)
creds := box.Credentials{
	ClientID:     "your-client-id",
	ClientSecret: "your-client-secret",
	EnterpriseID: "your-enterprise-id",
	AppAuth: box.AppAuth{
		PublicKeyID: "your-public-key-id",
		PrivateKey:  "your-private-key",
		PassPhrase: "your-passphrase",
	},
}
if err := client.Authenticate(creds); err != nil {
	log.Errorf("Failed to authenticate.", err)
}
Uploading a file

To upload a file you need to know the owner Id of the folder you want to upload the file to:

import "github.com/gildas/go-box"
import "github.com/gildas/go-logger"
import "github.com/gildas/go-request"

func UploadFile(context context.Context, client *box.Client, ownerID string, filename string, reader io.Reader) (*box.FileCollection, error) {
	log := logger.Must(logger.FromContext(context)).Child("box", "upload", "owner", ownerID)

	// Get the folder for the owner
	log.Debugf("Getting the folder for the owner.")
	folder, err := client.Folders.FindByName(context, ownerID)
	if err != nil {
		log.Errorf("Failed to get the folder for the owner.", err)
		return nil, err
	}

	return client.Files.Upload(context, &box.UploadOptions{
		Filename: filename,
		Parent:   folder.AsPathEntry(),
		Content:  request.ContentFromReader(reader),
	})
}

You can also upload payloads directly:

files, err := client.Files.Upload(context, &box.UploadOptions{
	Parent:   folder.AsPathEntry(),
	Filename: "test.json",
	Payload: struct {
		Name string `json:"name"`
	}{
		Name: "Test",
	},
})
Finding files

To find files, you can use the Find methods:

root, err := client.Folders.FindByID(context, "0")
entry, err := client.Files.FindByName(context, "test.json", root.AsPathEntry())

You can also find files by Id (coming from a previous upload, for example):

root, err := client.Folders.FindByID(context, "0")
entry, err := client.Files.FindByID(context, "1234567890", root.AsPathEntry())
Downloading a file

To download a file, you need the entry (see above):

downloaded, err := client.Files.Download(context, root.ItemCollection.Paths[0])

downloaded is a request.Content that you can use to read the content of the file.

Deleting a file

To delete a file:

err = client.Folders.Delete(context, root.ItemCollection.Paths[0])
Creating a folder

To create a folder, you need their parent folder:

root, err := client.Folders.FindByID(context, "0")
folder, err := client.Folders.Create(context, &box.FolderEntry{Name: "New Folder", Parent: root.AsPathEntry()})
Finding a folder

To find a folder, you can use the Find methods:

root, err := client.Folders.FindByID(context, "0")
entry, err := client.Folders.FindByName(context, "New Folder", root.AsPathEntry())

You can also find folders by Id (coming from a previous creation, for example):

root, err := client.Folders.FindByID(context, "0")
entry, err := client.Folders.FindByID(context, "1234567890", root.AsPathEntry())
Deleting a folder

To delete a folder:

err = client.Folders.Delete(context, root.ItemCollection.Paths[0])

To create a shared link:

link, err := client.SharedLinks.Create(context, &entry, nil)

You can also give some options to the shared link:

link, err := client.SharedLinks.Create(context, &entry, &box.SharedLinkOptions{
	Access: "open",
	Permissions: box.SharedLinkPermissions{
		CanDownload: true,
	},
	UnsharedAt: time.Now().Add(24 * time.Hour),
})
Logging

go-box uses go-logger for logging. The logs are bunyan compatible. You can either use the bunyan CLI to read them or use the lv tool to read them.

If you don't provider a logger, the client will create one for you that logs to os.Stderr with the INFO level.

To provide your own logger, you can do something like this (please have a look at go-logger for more information):

log := logger.Create("myapp", &logger.FileStream{Path: "myapp.log", FilterLevels: logger.NewLevelSet(logger.DEBUG)})
defer log.Flush()

client := box.NewClient(log.ToContext(context))
