Method Detail

enableAuth

public static void enableAuth(com.ning.http.client.AsyncHttpClient client,
              Signer signer)

Attaches the provided Signer to the AsyncHttpClient as a signature calculator. It is expected that key rotation and Challenge management is outside the scope of this method, so only the Keychain.currentKey() will be used, and signature content will be built according to the last Challenge provided to the Signer.rotateKeys(net.adamcin.httpsig.api.Challenge) method.

Parameters:

client - the AsyncHttpClient to use for

signer - the Signer to use for authentication. It's keys must be rotated separately.

login

public static Future<com.ning.http.client.Response> login(com.ning.http.client.AsyncHttpClient client,
                                          Signer signer,
                                          com.ning.http.client.Request loginRequest)
                                                   throws IOException

Executes and replays a login request until one is found which satisfies the Challenge being returned by the server, or until there are no more keys in the keychain.

Parameters:

client - the AsyncHttpClient to which the Signer will be attached

signer - the Signer used for login and subsequent signature authentication

loginRequest - the login Request to be executed and replayed while rotating the keychain

Returns:

a Future expecting a Response

Throws:

IOException - if a request throws an exception

login

public static <T> Future<T> login(com.ning.http.client.AsyncHttpClient client,
                  Signer signer,
                  com.ning.http.client.Request loginRequest,
                  com.ning.http.client.AsyncCompletionHandler<T> responseHandler)
                       throws IOException

Executes and replays a login request until one is found which satisfies the Challenge being returned by the server, or until there are no more keys in the keychain.

Type Parameters:

T - type parameter for completion handler

Parameters:

client - the AsyncHttpClient to which the Signer will be attached

signer - the Signer used for login and subsequent signature authentication

loginRequest - the login Request to be executed and replayed while rotating the keychain

responseHandler - an AsyncCompletionHandler of type T

Returns:

a Future of type T

Throws:

IOException - if thrown by a login request

escapeQueryString

public static String escapeQueryString(String query)

really? really? So much request munging happens after the AsyncSignatureCalculator is called...

Parameters:

query -

Returns:

getRequestLine

public static String getRequestLine(com.ning.http.client.Request request,
                    String requestLineFormat)

calculateSignature
