DGDiscogsClient

Swift client for the Discogs API.

This library is still in development.

Installation

CocoaPods (iOS 8+, OS X 10.9+) (Recommended)

You can install DGDiscogsClient via CocoaPods by adding to your Podfile:

    pod 'OAuthSwiftAlamofire'
    pod 'DGDiscogsClient', '0.0.1'

Swift Package Manager

You can install DGDiscogsClient via the Swift Package Manager by adding to your Package.swift file:

import PackageDescription

let package = Package(
    name: "YOUR_PROJECT_NAME",
    targets: [],
    dependencies: [
        .Package(url: "https://github.com/WunDaii/DGDiscogsClient.git", version: “0.0.1”,
    ]
)

Usage

Authorization

You must authorise the user with Discogs by using the auth flow provided by OAuthSwiftAlamofire.

  1. Create an OAuth1Swift object with your credentials:
oauthSwift = OAuth1Swift(
            consumerKey:    "YOUR_CONSUMER_KEY”,
            consumerSecret: “YOUR_CONSUMER_SECRET”,
            requestTokenUrl: "https://api.discogs.com/oauth/request_token",
            authorizeUrl:    "https://discogs.com/oauth/authorize",
            accessTokenUrl:  "https://api.discogs.com/oauth/access_token"
        )
  1. Add the RequestAdapter to DGDiscogsManager:
        DGDiscogsManager.sharedInstance.adapter = oauthSwift.requestAdapter
        let sessionManager = SessionManager.default
        sessionManager.adapter = oauthSwift.requestAdapter
  1. Authorize with OAuthSwift:
            let _ = oauthSwift.authorize(
                withCallbackURL: URL(string: "recordshelf://oauth-callback/discogs")!,
                success: { credential, response, parameters in
                    print(credential.oauthToken)
                    print(credential.oauthTokenSecret)
                    
                    UserDefaults.standard.set(credential.oauthToken, forKey: "oauth_token")
                    UserDefaults.standard.set(credential.oauthTokenSecret, forKey: "oauth_token_secret")
                    
                    self.load()
            },
                failure: { error in
                    print(error.localizedDescription)
            })
        }

Accessing the Discogs API

Overview

Each request on a DGDiscogs object returns an enum called 'result', that has two possible values: success and failure. The success value will pass the expected values from the request, whilst the failure value typically returns an NSError.

Examples
        DGDiscogsManager.sharedInstance.getAuthenticatedUser { (result) in
            
            switch result {
                
            case .success():
                print("Successful")
                break
                
            case .failure(error: let error):
                print("There was an error: \(error?.localizedDescription)")
                break
                
            default:
                break
            }
        }
        let user = DGDiscogsManager.sharedInstance.user

        DGDiscogsManager.sharedInstance.user.getOrders { (result) in
            
            switch result {
                
            case .success(pagination: _, orders: let orders):
                
                guard
                    let orders = orders
                    else { return }
                
                print("The user has made \(orders.count) orders.")
                break
                
            case .failure(error: let error):
                print("There was an error: \(error?.localizedDescription)")
                break
                
            default:
                break
            }
            
        }

Notes

  • You may compare DGDiscogsItems using the == operator, as this will compare each item's discogsID and itemType values.
  • In requests where pagination is possible, you may omit the pagination: parameter when calling the method. This will default to a DGDiscogsUtils.Pagination with 20 items per page for page 1.
