Public Class Methods

api_enabled?(url) click to toggle source

Check if there is an enabled API in a Prestashop instance. @param url [String] base URL of the Prestashop installation. Do not append “/api” to it, the gem does it internally.

E.g. use "http://my.prestashop.com", not "http://my.prestashop.com/api"

@return [boolean] true if the API is enabled, false if it is disabled @raise [RestClient::Exception] if there is an error during HTTP GET @raise [StandardError] if a response different from 401 or 503 is received (not counting redirect responses,

  res = RestClient::Resource.new api_uri, user: '', password: ''
  begin
    response = res.get
    # We don't send an API key, so an HTTP error code should be returned. Execution shouldn't reach here normally.
    raise StandardError.new "Expected 401 or 503 response from Prestashop API #{api_uri} without key, instead received <#{response.code}> #{response.body}"
  rescue RestClient::Exception => e

Check if an API key is valid. @param url [String] base URL of the Prestashop installation. Do not append “/api” to it, the gem does it internally.
