State Property
Specifies the state parameter of the authorization request or response.
Syntax
oauthclient.getState([callback]) oauthclient.setState( state, [callback])
Default Value
""
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for the getState([callback]) method is defined as:
function(err, data){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'data' is the value returned by the method.
The callback for the setState([callback]) method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
This parameter contains an opaque value used by the client to maintain state between the request and callback. If this parameter was present in the authorization request, the server should include the same value in its response.
