go get github.com/hbagdi/go-unsplash/unsplashThis library has a single dependency on Google's go-querystring.
When using the Unsplash API, you need to make sure to abide by their API guidelines and API Terms.
Sign up on Unsplash.com and register as a developer.
You can then create a new application and use the AppID and Secret for authentication.
Please open an issue in this repository if you need help or want to report a bug.

Once you've installed the library using go get, import it to your go project:
import "github.com/hbagdi/go-unsplash/unsplash"Authentication is not handled by directly by go-unsplash.
Instead, pass an http.Client that can handle authentication for you.
You can use libraries such as oauth2.
Please note that all calls will include the OAuth token and hence, http.Client should not be shared between users.
Note that if you're just using actions that require the public permission scope, only the AppID is required.
An instance of unsplash can be created using New().
The http.Client supplied will be used to make requests to the API.
ts := oauth2.StaticTokenSource(
// note Client-ID in front of the access token
&oauth2.Token{AccessToken: "Client-ID Your-access-token"},
)
client := oauth2.NewClient(oauth2.NoContext, ts)
//use the http.Client to instantiate unsplash
unsplash := unsplash.New(client)
// requests can be now made to the API
randomPhoto, _ , err := unsplash.RandomPhoto(nil)All API calls return an error as second or third return object. All successful calls will return nil in place of this return. Further, go-unsplash has errors defined as types for better error handling.
randomPhoto, _ , err := unsplash.RandomPhoto(nil)
if err != nil {
//handle error
}Most API methods return a *Response along-with the result of the call.
This struct contains paging and rate-limit information.
Pagination is currently supported by supplying a page number in the ListOpt. The NextPage field in Response can be used to get the next page number.
searchOpt := &SearchOpt{Query : "Batman"}
photos, resp, err := unsplash.Search.Photos(searchOpt)
if err != nil {
return
}
// process photos
for _,photo := range *photos {
fmt.Println(*photo.ID)
}
// get next
if !resp.HasNextPage {
return
}
searchOpt.Page = resp.NextPage
photos, resp ,err = unsplash.Search.Photos(searchOpt)
//photos now has next page of the search resultUnsplash.Photos is of type PhotosService.
It provides various methods for querying the /photos endpoint of the API.
You can get a single random photo or multiple depending upon opt. If opt is nil, then a single random photo is returned. Random photos satisfy all the parameters specified in *RandomPhotoOpt.
photos, resp, err := unsplash.Photos.Random(nil)
assert.Nil(err)
assert.NotNil(photos)

photos, resp, err = unsplash.Photos.Random(&opt)
assert.Nil(err)
assert.NotNil(photos)
assert.NotNil(resp)
assert.Equal(3, len(*photos))Get all photos on unsplash.com.
Obviously, this is a huge list and hence can be paginated through.

fmt.Println("error with opt")
return
}
count := 0

if err != nil {
fmt.Println("error")
return
}
//process photos
for _, c := range *photos {
fmt.Printf("%d : %d\n", count, *c.ID)
count += 1
}
//go for next page
if !resp.HasNextPage {
return
}
opt.Page = resp.NextPage
}Get all curated photos on unsplash.com.
