/**
|
|
* A service client for the Amazon ID OAuth 2 flow.
|
|
*
|
|
* The sole purpose of this subclass is to make sure the POST params
|
|
* for cURL are provided as an urlencoded string rather than an array.
|
|
* This is because Amazon requires COntent-Type header to be application/x-www-form-urlencoded,
|
|
* which cURL overrides to multipart/form-data when POST fields are provided as an array
|
|
*
|
|
* The only difference from Oauth2CLient in authenticate() method is http_build_query()
|
|
* wrapped around $params. request() and parseRequestResult() methods are exact copies
|
|
* from Oauth2Client. They are copied here because private scope does not allow calling them
|
|
* from subclass.
