tl;dr I'm receiving:
JSON text did not start with array or object and option to allow fragments not set.if i'm trying to receive a token andNo refresh token available in the session!if I'm trying to renew a token.
I'm trying to setup the token refresh for the Objective-C Spotify iOS SDK beta-25 in Swift 3. I'm using a Heroku Server and the Ruby script provided by Spotify, changed to my credentials.
require 'sinatra'
require 'net/http'
require 'net/https'
require 'base64'
require 'encrypted_strings'
require 'json'
CLIENT_ID = ENV['xxx']
CLIENT_SECRET = ENV['xxx']
ENCRYPTION_SECRET = ENV['xxx']
CLIENT_CALLBACK_URL = ENV['xxx://returnafterlogin']
AUTH_HEADER = "Basic " + Base64.strict_encode64(CLIENT_ID + ":" + CLIENT_SECRET)
SPOTIFY_ACCOUNTS_ENDPOINT = URI.parse("https://accounts.spotify.com")
get '/' do
"Working"
end
post '/swap' do
# This call takes a single POST parameter, "code", which
# it combines with your client ID, secret and callback
# URL to get an OAuth token from the Spotify Auth Service,
# which it will pass back to the caller in a JSON payload.
auth_code = params[:code]
http = Net::HTTP.new(SPOTIFY_ACCOUNTS_ENDPOINT.host, SPOTIFY_ACCOUNTS_ENDPOINT.port)
http.use_ssl = true
request = Net::HTTP::Post.new("/api/token")
request.add_field("Authorization", AUTH_HEADER)
request.form_data = {
"grant_type" => "authorization_code",
"redirect_uri" => CLIENT_CALLBACK_URL,
"code" => auth_code
}
response = http.request(request)
# encrypt the refresh token before forwarding to the client
if response.code.to_i == 200
token_data = JSON.parse(response.body)
refresh_token = token_data["refresh_token"]
encrypted_token = refresh_token.encrypt(:symmetric, :password => ENCRYPTION_SECRET)
token_data["refresh_token"] = encrypted_token
response.body = JSON.dump(token_data)
end
status response.code.to_i
return response.body
end
post '/refresh' do
# Request a new access token using the POST:ed refresh token
http = Net::HTTP.new(SPOTIFY_ACCOUNTS_ENDPOINT.host, SPOTIFY_ACCOUNTS_ENDPOINT.port)
http.use_ssl = true
request = Net::HTTP::Post.new("/api/token")
request.add_field("Authorization", AUTH_HEADER)
encrypted_token = params[:refresh_token]
refresh_token = encrypted_token.decrypt(:symmetric, :password => ENCRYPTION_SECRET)
request.form_data = {
"grant_type" => "refresh_token",
"refresh_token" => refresh_token
}
response = http.request(request)
status response.code.to_i
return response.body
end
Set by:
SPTAuth.defaultInstance().tokenSwapURL = URL(string: SpotifyCredentials.tokenSwapURLSwap)
SPTAuth.defaultInstance().tokenRefreshURL = URL(string: SpotifyCredentials.tokenSwapURLRefresh)
Now the user is not able to login anymore and I'm receiving the error posted on top. If I'm deleting tokenSwapURL and tokenRefreshURL, everything works again, but the User has to re-auth every 60 minutes.
If I'm trying to refresh the Token with an already logged in user, I receive:
"No refresh token available in the session!"
if SPTAuth.defaultInstance().session != nil {
print("needs login")
SPTAuth.defaultInstance().renewSession(SPTAuth.defaultInstance().session, callback: { error, session in
if error != nil {
print("\(error?.localizedDescription)") // "No refresh token available in the session!"
return
}
})
}
What am I missing? Help is very appreciated.
