A go library to easily consume Flickr API. The project is currently under heavy development, so it hasn't a version number yet.

flickr aims to expose a Go Api matching Flickr REST Api, so that you don't need to build HTTP requests and parse HTTP response manually. For example, the Flickr method flickr.photosets.create is implemented with the Create function in the flickr/photosets package:

import "fmt"
import "gopkg.in/masci/flickr.v2"
import "gopkg.in/masci/flickr.v2/photosets"

// create an API client with credentials
client := flickr.NewFlickrClient("your_apikey", "your_apisecret")
client.OAuthToken = "your_token"
client.OAuthTokenSecret = "your_tokenSecret"

response, _ := photosets.Create(client, "My Set", "Description", "primary_photo_id")
fmt.Println("New photoset created:", response.Photoset.Id)

flickr responses implement flickr.FlickrResponse interface. A response contains error codes and error messages (if any) produced by Flickr or the specific data returned by the api call. Different methods may return different kind of responses.

There are a number of functions that don't map any actual Flickr Api method (see below for the detailed list). For example, to upload a photo, you call the UploadFile or UploadReader functions in the flickr package:

import "gopkg.in/masci/flickr.v2"


// upload the image file with default (nil) options
resp, err := flickr.UploadFile(client, "/path/to/image", nil)

Files are uploaded through an io.Pipe fueled in a separate goroutine, so the process is pretty efficient.

Several api calls must be authenticated and authorized: flickr only supports OAuth since the original token-based method has been deprecated by Flickr. This is an example describing the OAuth worflow from a command line application:

import "gopkg.in/masci/flickr.v2"

client := flickr.NewFlickrClient("your_apikey", "your_apisecret")

// first, get a request token
requestTok, _ := flickr.GetRequestToken(client)

// build the authorizatin URL
url, _ := flickr.GetAuthorizeUrl(client, requestTok)

// ask user to hit the authorization url with
// their browser, authorize this application and coming
// back with the confirmation token

// finally, get the access token, setup the client and start making requests
accessTok, err := flickr.GetAccessToken(client, requestTok, "oauth_confirmation_code")
client.OAuthToken = accessTok.OAuthToken
client.OAuthTokenSecret = accessTok.OAuthTokenSecret

Only a small part of the Flickr Api is implemented as Go functions: even if it's quite simple to write the code for the mapping, I only did it for methods I actually need in my projects (contributions well accepted). Anyway, if you need to call a Flickr Api method that wasn't already mapped, you can do it manually:

import "fmt"
import "gopkg.in/masci/flickr.v2"

client := flickr.NewFlickrClient("your_apikey", "your_apisecret")
client.Init()
client.Args.Set("method", "flickr.cameras.getBrandModels")
client.Args.Set("brand", "nikon")

client.OAuthSign()
response := &flickr.BasicResponse{}
err := flickr.DoGet(client, response)

if err != nil {
    fmt.Printf("Error: %s", err)
} else {
    fmt.Println("Api response:", response.Extra)
}

The latest version v2 only supports go 1.6 and above, for Go < 1.6 use the v1 package:

go get gopkg.in/masci/flickr.v1
