Playlyfe Go SDK

This is the official OAuth 2.0 Go or Golang client SDK for the Playlyfe API. It supports the client_credentials and authorization code OAuth 2.0 flows. For a complete API Reference checkout Playlyfe Developers for more information.

Examples

The Playlyfe class allows you to make rest api calls like GET, POST, .. etc.
To get started create a new playlyfe object using client credentials flow and then start making requests

import "github.com/playlyfe/playlyfe-go-sdk"

type Player struct {
    ID string `json:"id"`
    Alias string `json:"alias"`
}

var johny Player

func main() { 
    pl := playlyfe.NewClientV2("Your client id", "Your client secret", nil, nil)
    err := pl.Get("/runtime/player", playlyfe.H{"player_id": "johny"}, johny)  // To get player profile
}

Install

go get github.com/playlyfe/playlyfe-go-sdk

Using

Create a client

If you haven't created a client for your game yet just head over to Playlyfe and login into your account, and go to the game settings and click on client.

###1. Client Credentials Flow In the client page select Yes for both the first and second questions

import "github.com/playlyfe/playlyfe-go-sdk"

pl := playlyfe.NewClientV2("Your client id", "Your client secret", nil, nil)

###2. Authorization Code Flow In the client page select yes for the first question and no for the second

import "github.com/playlyfe/playlyfe-go-sdk"

pl := playlyfe.NewCodeV2("Your client id", "Your client secret", "redirect_uri", nil, nil)

In development the sdk caches the access token in memory so you don"t need to the persist access token object. But in production it is highly recommended to persist the token to a database. It is very simple and easy to do it with redis. You can see the test cases for more examples.

In production you need to pass the Load and Store functions whose signature is like this,

load func() (token string, expires_at int64) {
    println("Loading from redis")
    return "", 50
},
store func(token string, expires_at int64) {
    println("Storing to redis")
}

3. Custom Login Flow using JWT(JSON Web Token)

In the client page select no for the first question and yes for the second

import "github.com/playlyfe/playlyfe-go-sdk"

token, err := playlyfe.createJWT("your client_id", "your client_secret", 
    "player_id", // The player id associated with your user
    []string{"player.runtime.read", "player.runtime.write"}, // The scopes the player has access to
    3600; // 1 hour expiry Time
)

This is used to create jwt token which can be created when your user is authenticated. This token can then be sent to the frontend and or stored in your session. With this token the user can directly send requests to the Playlyfe API as the player.

Client Scopes

Your client has certain access control restrictions. There are 3 kind of resources in the Playlyfe REST API they are,

1./admin -> routes for you to perform admin actions like making a player join a team

2./design -> routes for you to make design changes programmatically

3./runtime -> routes which the users will generally use like getting a player profile, playing an action

The resources accessible to this client can be configured to have a read permission that means only GET requests will work.

The resources accessible to this client can be configured to have a write permission that means only POST, PATCH, PUT, DELETE requests will work.

The version restriction is only for the design resource and can be used to restrict the client from accessing any version of the game design other than the one specified. By default it allows all.

If access to a route is not allowed and then you make a request to that route then you will get an error like this,

{
  "error": "access_denied",
  "error_description": "You are not allowed to access this api route"
}

Methods

API

error API("GET", // The request method can be GET/POST/PUT/PATCH/DELETE
    "", // The api route to get data from
    playlyfe.H{}, // The query params that you want to send to the route
    struct{} ,// The data you want to post to the api
    result interface{}, // The unmarshalled data
    false // Whether you want the response to be in raw string form or json
)

Get

error Get("", // The api route to get data from
    playlyfe.H{}, // The query params that you want to send to the,
    result interface{}, // The unmarshalled data
)

Post

error Post("", // The api route to post data to
    playlyfe.H{}, // The query params that you want to send to the route
    struct{},// The data you want to post to the api
    result interface{}, // The unmarshalled data
)

Patch

error Patch("" // The api route to patch data
    playlyfe.H{} // The query params that you want to send to the route
    struct{} ,// The data you want to post to the api
    result interface{}, // The unmarshalled data
)

Put

error Put("" // The api route to put data
    playlyfe.H{}, // The query params that you want to send to the route
    struct{} ,// The data you want to post to the api
    result interface{}, // The unmarshalled data
)

Delete

error Delete("" // The api route to delete the component
    playlyfe.H{} // The query params that you want to send to the route,
    result interface{}, // The unmarshalled data
)

Get Login URL

GetLoginURL() string
//This will return the url to which the user needs to be redirected for the user to login.

Exchange Code

ExchangeCode(code string)
//This is used in the auth code flow so that the sdk can get the access token.
//Before any request to the playlyfe api is made this has to be called atleast once.
//This should be called in the the route/controller which you specified in your redirect_uri

Errors
An *Error is returned whenever an error from the PlaylyfeAPI occurs in each call.The Error contains a Name and Description field which can be used to determine the type of error that occurred.

You have to type cast the error to a *PlaylyfeError first like this,

err := pl.Get("/player", playlyfe.H{"player_id": "student1"}, &player)
if pe, ok := err.(*playlyfe.Error); ok {
    return pe
} else {
    panic(err) // do what needs to be done on this type of error
}
