Simple webpage for invitations for Apache OpenWhisk Slack Community.
Join our Slack: https://openwhisk.apache.org/slack.html
The backend is implemented as a serverless action with an API gateway route.
Configure the wsk CLI with authentication and host
Create the action using wsk CLI and set default parameters
wsk action create slackinvite action.js -p org "myslackteam" -p slacktoken "xop-12345..."
The org is the Slack team name, usually the hostname from your .slack.com. The slacktoken is a token for a user with admin access. You can get one from https://api.slack.com/docs/oauth-test-tokens Recommend creating a bot user with admin to use for invites.
Verify the action by invoking with the wsk CLI
wsk action invoke slackinvite -p email "user@example.com"
The action should do a http call to the slack API using the team host and token, then Slack will send the invite to the email provided.
Create a public url to invoke the action using wsk CLI
wsk api-experimental create /openwhisk-team /slackinvite GET slackinvite
The command will print the new url created
ok: created api /slackinvite GET for action slackinvite https://21ef035.api-gw.mybluemix.net/openwhisk-team/slackinvite
Verify the exposed url by invoking using the curl CLI or a web browser
curl -X GET https://21ef035.api-gw.mybluemix.net/openwhisk-team/slackinvite?email=user@example.com
Edit the line var actionUrl = "https://..."; and replace the value with your new url that expose your new action.
Create a new GitHub repo, then go to settings, and set the master branch as GitHub Pages. Push the modified index.html to the new repo, then your webpage will be accesible from https://$username.github.io/$reponame
