Awesome USPS
This library is meant to interface with the web services of USPS. It grew out of early dabbling of the USPS_Tracker plugin. The goal is to abstract the features that are most frequently used into a pleasant and consistent Ruby API. Awesome USPS started as an extension of Active Shipping but at the moment I am still struggling with how best to accomplish integration. While working on the problem I decided to release my current work as a separate plugin for all to enjoy. Next up the Awesome USPS gem.
Prerequisites
Hrpicot for parsing the XML. To install run sudo gem install Hpricot
mocha for the tests
Download & Installation
Currently this library is available on GitHub:
You will need to get Git if you don't have it. Then:
script/plugin install git://github.com/FotoVerite/awesome_usps.git
if using rails prior to 2.1:
git clone git://github.com/FotoVerite/awesome_usps.git
(That URL is case-sensitive, so watch out.)
Awesome USPS includes an init.rb file. This means that Rails will automatically load it on startup. Check out git-archive for exporting the file tree from your repository to your vendor directory.
Gem and tarball forthcoming on rubyforge.
Notice about using the USPS API
USPS can be a bit frustrating when starting working with them. First you must apply for a USPS web tools account This will net you a USPS user name assigned by them and a password. The password is for older versions of their api so you do not need to concern yourself with it.
Secondly you only have accesses to the Testing Server. You should run the canned responses to make sure everything is setup up correctly.
USPS.canned_tracking
or
USPS.canned_us_shipping
You should get the response "Everything is Working"
From there you need to email USPS for your account to be changed over to production.
#TODO Explain what must be done for Labels API
Sample Usage
#In your environment.rb or production.rb
require 'active_shipping'
include FotoVerite::AwesomeUsps
# Then to access the plugin you much create an instance of USPS class
USPS = USPS.new('Your user name')
# Package up a poster and a Wii for your nephew.
# Note the Package Module has been taken directly from Active Shipping. Thank you James MacAulay for developing such great code.
packages = [
Package.new( 100, # 100 grams
[93,10], # 93 cm long, 10 cm diameter
:cylinder => true), # cylinders have different volume calculations
Package.new( (7.5 * 16), # 7.5 lbs, times 16 oz/lb.
[15, 10, 4.5], # 15x10x4.5 inches
:units => :imperial) # not grams, not centimetres
]
To track a package
USPS.track("Number")
#This will return an array of tracking events example shown below
[{:eventzipcode=>"33436", :event=>"Arrival at Unit", :eventtime=>"7:23 am", :eventdate=>"June 14, 2008", :eventcity=>"BOYNTON BEACH", :eventstate=>"FL"},
{:eventzipcode=>"32862", :event=>"Processed", :eventtime=>"9:50 pm", :eventdate=>"June 13, 2008", :eventcity=>"ORLANDO", :eventstate=>"FL"},
{:eventzipcode=>"07032", :event=>"Processed", :eventtime=>"1:19 am", :eventdate=>"June 13, 2008", :eventcity=>"KEARNY", :eventstate=>"NJ"},
{:eventzipcode=>"07024", :event=>"Acceptance", :eventtime=>"3:03 pm", :eventdate=>"June 12, 2008", :eventcity=>"FORT LEE", :eventstate=>"NJ"}]
#Loop through and display as you wish
To get rates for a single or group of packages.
# Package up a poster and a Wii for your nephew.
# Note the Package Module has been taken directly from Active Shipping. Thank you James MacAulay for developing such great code.
packages = [
Package.new( 100, # 100 grams
[93,10], # 93 cm long, 10 cm diameter
:cylinder => true), # cylinders have different volume calculations
Package.new( (7.5 * 16), # 7.5 lbs, times 16 oz/lb.
[15, 10, 4.5], # 15x10x4.5 inches
:units => :imperial) # not grams, not centimetres
]
#Then user either the domestic rates or world rates method
USPS.domestic_rates(ZIP, Packages, options={})
USPS.world_rates(Country, Packages, options={})
#Both will return a hash organized by Package and service
{"Package1"=>{"Priority Mail International Flat-Rate Box"=>"38.95", "USPS GXG Envelopes"=>"97.00", "Priority Mail International Large Flat-Rate
Box"=>"49.95", "Priority Mail International"=>"48.00", "Express Mail International (EMS) Flat-Rate Envelope"=>"25.95", "Express Mail International
(EMS)"=>"55.50", "Global Express Guaranteed Non-Document Non-Rectangular"=>"97.00", "Global Express Guaranteed Non-Document Rectangular"=>"97.00",
"Global Express Guaranteed"=>"97.00"}, "Package2"=>{"Priority Mail International Flat-Rate Box"=>"38.95", "USPS GXG Envelopes"=>"148.00",
"Priority Mail International Large Flat-Rate Box"=>"49.95", "Priority Mail International"=>"81.75", "Express Mail International (EMS) Flat-Rate
Envelope"=>"25.95", "Express Mail International (EMS)"=>"100.50", "Global Express Guaranteed Non-Document Non-Rectangular"=>"148.00", "Global Express
Guaranteed Non-Document Rectangular"=>"148.00", "Global Express Guaranteed"=>"148.00"}}
#To access a rate hash for use you can do
hash = USPS.world_rates(Country, Packages, options={})
hash[Package1][Priority Mail International]
#You can also loop through and sort

Contributing
Yes, please! I am a young Ruby Developer who is making plenty mistakes. Any improvements to the coding structure or patches would be highly appreciated.
The nicest way to submit changes would be to set up a GitHub account and fork this project, then initiate a pull request when you want your changes looked at. You can also make a patch (preferably with git-diff) and email to [email protected]
