Twilio Verify Ruby on Railsクイックスタート

With just a few lines of code, your Rails application can verify phone numbers and add an additional layer of security with Twilio Verify.

This Ruby Verify Quickstart will teach you how to do this using our Verify REST API, the Twilio Ruby helper library, and Ruby on Rails to ease development.

このクイックスタートでは、下記のことを学んでいきます:

  1. Twilioにサインアップ
  2. メッセージを送受信できるように開発環境をセットアップする
  3. Send your first SMS phone verification
  4. Check verification codes

Twilioにサインアップ

If you already have a Twilio account, you’re all set here! Feel free to jump to the next step.

Before you can send an SMS from Python, you'll need to sign up for a Twilio account or sign into your existing account.

You can sign up for a free Twilio trial account here.

  • When you sign up, you'll be asked to verify your personal phone number. This helps Twilio verify your identity and also allows you to send test verification messages to your phone from your Twilio account while in trial mode. This phone verification step is exactly what you'll learn how to build in this tutorial!
  • Once you verify your number, you'll be asked to create a project. For the sake of this tutorial, you can click on the "Learn and Explore" template. Give your project a name, or just click "skip remaining steps" to continue with the default.
  • Once you get through the project creation flow, you'll arrive at your project dashboard in the Twilio Console. This is where you'll be able to access your Account SID, authentication token, create a verification service, and more.

Do I need a phone number?

If you've sent SMS with Twilio in the past, you might remember needing to buy a phone number. With Twilio Verify, we take care of that for you! The Verify API selects the best routes for quickly and reliably delivering verification codes globally.

Now that you have a Twilio account and a verification service, you can start writing some code! To make things even easier, we'll next install Twilio's official helper for Ruby applications.

RubyとTwilioヘルパーライブラリーをインストールする

If you’ve gone through one of our other Ruby Quickstarts already and have Ruby and the Twilio Ruby helper library installed, you can skip this step and get straight to sending your first verification.

To start a phone verification, you’ll need to have Ruby and the Twilio Ruby helper library installed.

Rubyをインストールする

If you're using Mac, you probably already have Ruby installed but an older version. You can use homebrew to install the latest version using the following command:

brew install ruby 

If you’re on a Linux machine, you can install it using your default package manager, for example for Ubuntu:

sudo apt-get install ruby-full

For other distributions, you can find the command in this listing.

You can check if Ruby is installed and which version by opening up a terminal and running the following command:

ruby --version

下記のように表示されます:

$ ruby --version
ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-darwin18]

Windows users can use RubyInstaller.

Twilio’s Ruby SDK supports older versions of Ruby. But for this quickstart, we recommend using at least Ruby 2.3 for compatibility with some of the dependencies used.

検証アプリケーションをクローンおよびセットアップする

Start by cloning our Rails repository.

git clone git@github.com:TwilioDevEd/verify-v2-quickstart-rails.git

If you don't have git installed or prefer to download the source code you can grab a zip file of the project here.

Set up your environment and install dependencies

You'll need to have bundler installed in your Ruby environment, simply run the command:

gem install bundler

Once it's installed, you'll be able to install all the quickstart's dependencies by navigating to its directory and running bundler:

cd verify-v2-quickstart-rails

bundle install

Copy .env.example to .env. This is where we'll store sensitive data in environment variables.

cp .env.example .env

the application will automatically read and load those environments variables from the .env file. Finally, all that's left to do is run the migrations which will prepare an SQLite database automatically for you and start the development server:

rails db:migrate
rails server

If your credentials are set up correctly you'll soon get a message that the app is up!

Use the Rails Twilio Verify Demo

Navigate to http://localhost:3000/register. You should see a registration form that looks like this:

sign up form with phone verification
Enter your phone number and choose which channel to request verification over. Finally hit the green Sign Up button and wait. You'll either receive a phone call or an SMS with the verification token. If you requested a phone call, as an additional security feature you may need to interact to proceed (the call will tell you to enter a number on the phone keypad).

Enter the token into the Verification entry form and click 'Verify':

verification entry form

これで、デモアプリケーションはTwilioの電話番号検証で保護されました! ログアウトして他のチャンネルもお試しいただけます。

Your demo app is now keeping fraudulent users from registering with your business and polluting your database. Next, check out all of the variables and options available to you in the Phone Verification API Reference. Also, to protect your customers in an ongoing manner (with this same codebase) try the Rails Authy Two-Factor Authentication Quickstart.

After that, visit the Docs for more Account Security demos and tutorials and web applications using all of Twilio's products.
