TWReporter's Golang Backend API

Environment

Development

Please make sure that you install Glide package manager in the environment.

cd $GOPATH/src/twreporter.org/go-api
glide install                           # Install packages and dependencies

// use Makefile
make start 
// or 
go run main.go                          # Run without live-reloading
Live Reloading

Note that GOPATH/bin should be in your PATH.

go get github.com/codegangsta/gin
gin                                     # Run with live-reloading
Production
go build
./go-api

Dependencies Setup and Configurations

There are two major dependencies of go-api, one is MySQL database, another is MongoDB.
MySQL DB stores membership data, which is related to users.
MongoDB stores news entities, which is the content that go-api provides.

Install docker-compose

docker-compose installation

Start/Stop MySQL and MongoDB with default settings
// start MySQL and MongoDB
make env-up

// stop MySQL and MongoDB
make env-down
Configure MySQL Connection

Copy configs/config.example.json and rename as configs/config.json. Change DBSettings fields to connect to your own database, like following example.

  "DBSettings": {
    "Name":     "test_membership",
    "User":     "test_membership",
    "Password": "test_membership",
    "Address":  "127.0.0.1",
    "Port":     "3306"
  },
Configure MongoDB Connection

Copy configs/config.example.json and rename as configs/config.json. Change MongoDBSettings fields to connect to your own database, like following example.

  "MongoDBSettings": {
    "URL": "localhost",
    "DBName": "plate",
    "Timeout": 5
  },
AWS SES Setup

Currently the source code sends email through AWS SES,

If you want to send email through your AWS SES, just put your AWS SES config under ~/.aws/credentials

[default]
aws_access_key_id = ${AWS_ACCESS_KEY_ID}
aws_secret_access_key = ${AWS_SECRET_ACCESS_KEY}

Otherwise, you have to change the utils/mail.go to integrate with your email service.

Functional Testing

Prerequisite
  • Make sure the environment you run the test has a running MySQL server and MongoDB server
How To Run Tests
// use Makefile
make test

// or

go test $(glide novendor)

// or print logs
go test -v $(glide novendor)

RESTful API

go-api is a RESTful API built by golang.

It provides several RESTful web services, including

USERS

Signin
  • workflow:
    1. user send POST request to v1/signin endpoint
    2. system will send activation email to user
    3. user click activation link(<a> link) in the email body
    4. go-api server verifies the token
    5. if verified, user will get a jwt(Json Web Token)
    6. user can use JWT to send personal requests(go-api server will verfiy the jwt).
OAuth

Before Oauth signin, you have to setup the oauth config in configs/config.json

  "OauthSettings": {
    "FacebookSettings": {
      "ID": "${ID_YOU_GET_FROM_FACEBOOK_DEVELOPER}",
      "Secret": "${SECRECT_YOU_GET_FROM_FACEBOOK_DEVELOPER}",
      "URL": "http://${GO_API_SERVER_HOST_NAME}:8080/v1/auth/facebook/callback",
      "Statestr": "${THE_STATE_YOU_WANT_TO_USE_IN_AUTHORIZE_URL}"
    },
    "GoogleSettings": {
      "Id": "${ID_YOU_GET_FROM_GOOGLE_DEVELOPER}",
      "Secret": "${SECRECT_YOU_GET_FROM_FACEBOOK_DEVELOPER}",
      "Url": "http://${GO_API_SERVER_HOST_NAME}:8080/v1/auth/google/callback",
      "Statestr": "THE_STATE_YOU_WANT_TO_USE_IN_AUTHORIZE_URL"
    }
  },
  "ConsumerSettings": {
    "Domain": "${CONSUMER_DOMAIN_NAME}",
    "Protocol": "http",
    "Host": "${CONSUMER_HOST_NAME}",
    "Port": "3000"
  },
  • workflow
    1. users click oauth login button, broswer send GET request to /v1/oauth/goolge or /v1/oauth/facebook endpoints(on go-api server)
    2. go-api server redirect users to google or facebook oauth confirmation page
    3. on goolge/facebook oauth page, user input account and password
    4. if verified by facebook/google, facebook/google will redirect user to /v1/oauth/google/callback or /v1/oauth/facebook/callback endpoints on go-api server.
    5. if verified by go-api server, go-api server will redirect user to customer page(here, will be ${ConsumerSettings.Protocol}://${ConsumerSettings.Host}:${ConsumerSettings.Port}/).
    6. jwt(Json Web Token) will be set in the response header(Set-Cookie: ${cookie}), and user can get the jwt from browser cookie.
    7. user can use JWT to send personal requests(go-api server will verfiy the jwt).
