CobotClient
A client for the Cobot API plus helpers.
Installation
Add this line to your application's Gemfile:
gem 'cobot_client'
And then execute:
$ bundle
Or install it yourself as:
$ gem install cobot_client
Usage
Installing navigation links on Cobot:
You can install links to your app into the navigation on Cobot. When users click the link an iframe pointing to the given iframe_url
will be shown.
client = CobotClient::ApiClient.new '<access token>'
CobotClient::NavigationLinkService.new(client, 'co-up').install_links [
CobotClient::NavigationLink.new(section: 'admin/manage', label: 'My App', iframe_url: 'http://example.com')]
Setting up automatic iframe resizing
When you install your app on Cobot you have to add the following to make sure the iframe on Cobot automatically gets resized according to the height of your page.
This only works for Ruby on Rails >= 3.2. If you are using anything else please take a look at the files involved and set it up manually.
Add this lines to your layout, before the closing </body>
tag:
<%= render 'cobot_client/resize_script' %>
This will automatically resize Cobot's iframe whenever a new page is loaded. To manually trigger a resize call window.Cobot.iframeResize()
.
The default script determine's the iframe height by calling jQuery('body').outerHeight()
. To provide your own height you can either pass it to the iframeResize
function or you can define a function window.Cobot.iframeHeight
.
When you display layers in the iframe that are positioned relative to the window you have to take into account how much the user scrolled down in the parent frame. For this purpose the script provides the property window.Cobot.scrollTop
, which returns the no. of pixels the user has scrolled down.
Generating URLs to the Cobot API
There is a module CobotClient::UrlHelper
. After you include it you can call cobot_url
. Examples:
cobot_url('co-up') # => 'https://co-up.cobot.me/'
cobot_url('co-up', '/api/user') # => 'https://co-up.cobot.me/api/user'
cobot_url('co-up', '/api/user', params: {x: 'y'}) # => 'https://co-up.cobot.me/api/user?x=y'
Calling the API
At the moment there are only a few high-level methods. For more details see the specs.
client = CobotClient::ApiClient.new('<access token>')
client.list_resources('<subdomain>')
For everything else you can use the low-level get/post/put/delete metods:
client.get 'www', '/user'
client.post 'my-subdomain', '/users', {"email": "joe@doe.com"}
You can also pass a URL instead of subdomain/path:
client.get 'https://www/cobot.me/user'
Error handling
In case of Cobot returning a 4xx or 5xx status code, the ApiClient
throws an exception that is a subclass of CobotClient::Exception
.
The most common exceptions encountered are CobotClient::NotFound
(404), CobotClient::Forbidden
(403), CobotClient::UnprocesseableEntity
(422) and CobotClient::TooManyRequests
(429).
To access the error message contained in the response, rescue the exception and http_body
on it:
begin
client = CobotClient::ApiClient.new('<access token>')
client.get('www', '/user')
rescue CobotClient::Exception => e
puts JSON.parse(e.http_body)
end
To access response headers, for example the Retry-After
header of a rate-limited request:
begin
client = CobotClient::ApiClient.new('<access token>')
client.get('www', '/user')
rescue CobotClient::TooManyRequests => e
puts e.response.headers[:retry_after].to_i
end
