我有这个 Ruby 文件：
新鲜桌面.rb：
require "rest_client"
require 'nokogiri'
class Freshdesk
# custom errors
class AlreadyExistedError < StandardError; end
class ConnectionError < StandardError; end
attr_accessor :base_url
def initialize(base_url, username, password)
@base_url = base_url
RestClient.add_before_execution_proc do | req, params |
req.basic_auth username, password
end
end
# Freshdesk API client support "GET" with id parameter optional
# Returns nil if there is no response
def self.fd_define_get(name, *args)
name = name.to_s
method_name = "get_" + name
define_method method_name do |*args|
uri = mapping(name)
uri.gsub!(/.xml/, "/#{args}.xml") if args.size > 0
begin
response = RestClient.get uri
rescue Exception
response = nil
end
end
end
# Freshdesk API client support "DELETE" with the required id parameter
def self.fd_define_delete(name, *args)
name = name.to_s
method_name = "delete_" + name
define_method method_name do |args|
uri = mapping(name)
raise StandardError, "An ID is required to delete" if args.size.eql? 0
uri.gsub!(/.xml/, "/#{args}.xml")
RestClient.delete uri
end
end
# Freshdesk API client support "POST" with the optional key, value parameter
#
# Will throw:
# AlreadyExistedError if there is exact copy of data in the server
# ConnectionError if there is connection problem with the server
def self.fd_define_post(name, *args)
name = name.to_s
method_name = "post_" + name
define_method method_name do |args|
raise StandardError, "Arguments are required to modify data" if args.size.eql? 0
uri = mapping(name)
builder = Nokogiri::XML::Builder.new do |xml|
xml.send(doc_name(name)) {
args.each do |key, value|
xml.send(key, value)
end
}
end
begin
response = RestClient.post uri, builder.to_xml, :content_type => "text/xml"
rescue RestClient::UnprocessableEntity
raise AlreadyExistedError, "Entry already existed"
rescue RestClient::InternalServerError
raise ConnectionError, "Connection to the server failed. Please check hostname"
rescue RestClient::Found
raise ConnectionError, "Connection to the server failed. Please check username/password"
rescue Exception => e3
raise
end
response
end
end
# Freshdesk API client support "PUT" with key, value parameter
#
# Will throw:
# ConnectionError if there is connection problem with the server
def self.fd_define_put(name, *args)
name = name.to_s
method_name = "put_" + name
define_method method_name do |args|
raise StandardError, "Arguments are required to modify data" if args.size.eql? 0
raise StandardError, "id is required to modify data" if args[:id].nil?
uri = mapping(name)
builder = Nokogiri::XML::Builder.new do |xml|
xml.send(doc_name(name)) {
args.each do |key, value|
xml.send(key, value)
end
}
end
begin
uri.gsub!(/.xml/, "/#{args[:id]}.xml")
response = RestClient.put uri, builder.to_xml, :content_type => "text/xml"
rescue RestClient::InternalServerError
raise ConnectionError, "Connection to the server failed. Please check hostname"
rescue RestClient::Found
raise ConnectionError, "Connection to the server failed. Please check username/password"
rescue Exception => e3
raise
end
response
end
end
[:tickets, :ticket_fields, :users, :forums, :solutions, :companies].each do |a|
fd_define_get a
fd_define_post a
fd_define_delete a
fd_define_put a
end
# Mapping of object name to url:
# tickets => helpdesk/tickets.xml
# ticket_fields => /ticket_fields.xml
# users => /contacts.xml
# forums => /categories.xml
# solutions => /solution/categories.xml
# companies => /customers.xml
def mapping(method_name)
path = case method_name
when "tickets" then File.join(@base_url + "helpdesk/tickets.xml")
when "ticket_fields" then File.join( @base_url, "ticket_fields.xml")
when "users" then File.join(@base_url, "contacts.xml")
when "forums" then File.join(@base_url + "categories.xml")
when "solutions" then File.join(@base_url + "solution/categories.xml")
when "companies" then File.join(@base_url + "customers.xml")
end
end
# match with the root name of xml document that freskdesk uses
def doc_name(name)
doc = case name
when "tickets" then "helpdesk_ticket"
when "ticket_fields" then "helpdesk-ticket-fields"
when "users" then "user"
when "companies" then "customer"
else raise StandardError, "No root object for this call"
end
end
end
要使用它，我会：
client = Freshdesk.new("http://website.freshdesk.com/", "API KEY", "X")
# example posts a ticket
client.post_tickets(:subject => 'This is from the rails app',:email => "mytestemail@example.com", :description => "This is from the ruby file bitches", :name => "Richard Ahn", :source => 2, :priority => 2, :name => "Joshua Siler")
然后，在我的控制台中，我这样做：
$ ruby freshdesk.rb
调用的信息client.post_tickets会发布到我的 Freshdesk 仪表板。
如何将它集成到我的 Rails 应用程序中？
我应该把带有类名的文件放在哪里FRESHDESK？
我该怎么办：
client = Freshdesk.new
client.post_tickets
如何将其与用户可以提交的表单链接起来？
