README.ROB:

copy client_secrets.json or create anew via https://console.developers.google.com/start/api?id=youtube

sudo apt install golang-go
go get -u google.golang.org/api/youtube/v3
go get -u github.com/BurntSushi/toml

cd ~/mt3.com/scripts/go
go run my_uploads.go errors.go oauth2.go

Recommended Go version: latest version

To run these code samples, you will need to install the dependent libraries via the "go get" command. See the client library's getting started guide for more detail: https://github.com/google/google-api-go-client/blob/master/GettingStarted.md

You also need to enable the YouTube Data API for the project associated with your developer credentials.

Authorization credentials

To run any sample that does not require user authorization, such as search_by_keyword.go, you need to replace the value of the developerKey constant with a valid API key:

const developerKey = "YOUR DEVELOPER KEY"

To run any sample that requires authorization on behalf of a user, such as retrieving the authenticated user's uploads, you need an OAuth 2.0 client ID and client secret pair. These can be created at the Google API console at https://developers.google.com/console. After creating your OAuth 2.0 credentials, download the client_secret.json file to the directory in which you are running these samples.

Running samples

Samples can be run with the standard "go run" command as long as your API key or OAuth 2.0 credentials are in place. The samples use the errors.go file to print out API errors, so you need to also include that file in the "go run" command. Samples that require authorization also require the oauth2.go file to be included in the "go run" command:

Example usages:

   go run search_by_keyword.go errors.go
   go run my_uploads.go errors.go oauth2.go
   go run upload_video.go errors.go oauth2.go --filename="sample_video.flv" --title="Test video" --keywords="golang test"

More information about the YouTube APIs can be found at https://developers.google.com/youtube.

Samples in this directory:

Authorize a request

Description: This code sample performs OAuth 2.0 authorization by checking for the presence of a local file that contains authorization credentials. If the file is not present, the script opens a browser and waits for a response, then saves the returned credentials locally.

List playlists

Methods: youtube.playlists.list
Description: This code sample calls the API's playlists.list method. Use command-line flags to define the parameters you want to use in the request as shown in the following examples:

# Retrieve playlists for a specified channel
go run playlists.go oauth.go errors.go --channelId=UC_x5XG1OV2P6uZZ5FSM9Ttw

# Retrieve authenticated user's playlists
go run playlists.go oauth.go errors.go --mine=true

Retrieve my uploads

Methods: youtube.channels.list, youtube.playlistItems.list
Description: This code sample calls the API's playlistItems.list method to retrieve a list of videos uploaded to the channel associated with the request. The code also calls the channels.list method with the mine parameter set to true to retrieve the playlist ID that identifies the channel's uploaded videos.

Search by keyword

Method: youtube.search.list
Description: This code sample calls the API's search.list method to retrieve search results associated with a particular keyword.

Upload a video

Method: youtube.videos.insert
Description: This code sample calls the API's videos.insert method to upload a video to the channel associated with the request.
