Cloudinary Go SDK

Cloudinary is a cloud service that offers a solution to a web application's entire image management pipeline.

Easily upload images to the cloud. Automatically perform smart image resizing, cropping and conversion without installing any complex software. Integrate Facebook or Twitter profile image extraction in a snap, in any dimension and style to match your website's graphics requirements. Images are seamlessly delivered through a fast CDN, and much much more.

Cloudinary offers comprehensive APIs and administration capabilities and is easy to integrate with any web application, existing or new.

Cloudinary provides URL and HTTP based APIs that can be easily integrated with any Web development framework.

For Go, Cloudinary provides a module for simplifying the integration even further.

Setup

To install Cloudinary Go SDK, use go get:

go get github.com/cloudinary/cloudinary-go

Usage

Configuration

Each request for building a URL of a remote cloud resource must have the CloudName parameter set. Each request to our secure APIs (e.g., image uploads, eager sprite generation) must have the ApiKey and ApiSecret parameters set. See API, URLs and access identifiers for more details.

Setting the CloudName, ApiKey and ApiSecret parameters can be done by initializing the Cloudinary object, or by using the CLOUDINARY_URL environment variable / system property.

The entry point of the library is the Cloudinary struct.

cld, _ := cloudinary.Create()

Here's an example of setting the configuration parameters programatically:

cld, _ := cloudinary.CreateFromParams('n07t21i7','123456789012345', 'abcdeghijklmnopqrstuvwxyz12')

Another example of setting the configuration parameters by providing the CLOUDINARY_URL value:

cld, _ := cloudinary.CreateFromUrl('cloudinary://123456789012345:abcdeghijklmnopqrstuvwxyz12@n07t21i7')

Upload

Assuming you have your Cloudinary configuration parameters defined (CloudName, ApiKey, ApiSecret), uploading to Cloudinary is very simple.

The following example uploads a local JPG to the cloud:

resp, err := cld.Upload.Upload(ctx, "my_picture.jpg", uploader.UploadParams{});

The uploaded image is assigned a randomly generated public ID. The image is immediately available for a download through a CDN:

println(resp.SecureURL)

// https://res.cloudinary.com/demo/image/upload/abcfrmo8zul1mafopawefg.jpg

You can also specify your own public ID:

resp, err := cld.Upload.Upload(ctx, "my_picture.jpg", uploader.UploadParams{PublicID: "sample_remote.jpg"});
if err != nil {...}
println(resp.SecureURL)

// https://res.cloudinary.com/demo/image/upload/sample_remote.jpg
