rubygems.org guides 翻译十一（RubyGems.org API）

Details on interacting with RubyGems.org over HTTP.

注意：这个API is a work in progress, and can use your help! RubyGems itself and the gemcutter gem use the API to push gems, add owners, and more.

• API Authorization: How to authenticate with RubyGems.org
• Gem Methods: Query or create gems to be hosted
• Gem Version Methods: Query for information about versions of a particular gem
• Gem Download Methods: Query for download statistics
• Owner Methods: Manage owners for gems
• Webhook Methods: Manage notifications for when gems are pushed
• Activity Methods: Query for information about site-wide activity
• Misc Methods: Various other interactions with the site

===========================================================

API Authorization

Some API calls require an Authorization header. To find your API key, click on your username when logged in toRubyGems.org and then click on ‘Edit Profile’. Here’s an example of using an API key:

$ curl -H 'Authorization:YOUR_API_KEY' \
  https://rubygems.org/api/v1/some_api_call.json

Ruby Library

You can also interact with RubyGems.org using Ruby.

The gems client provides a Ruby interface to all the resources listed below. This library has full documentationthat includes some basic usage examples in the README. You can install the library with the command:

gem install gems

Gem Methods

GET - /api/v1/gems/[GEM NAME].(json|xml|yaml)

Returns some basic information about the given gem. See below an example response for the gem “rails” in JSON format:
