Method Detail

authorize

public Auth.TokenDetails authorize(Auth.TokenParams params,
                                   Auth.AuthOptions options)
                            throws AblyException

Ensure valid auth credentials are present. This may rely in an already-known and valid token, and will obtain a new token if necessary or explicitly requested. Authorization will use the parameters supplied on construction except where overridden with the options supplied in the call.

Parameters:

params - an object containing the request params: - key: (optional) the key to use; if not specified, the key passed in constructing the Rest interface may be used - ttl: (optional) the requested life of any new token in ms. If none is specified a default of 1 hour is provided. The maximum lifetime is 24hours; any request exceeeding that lifetime will be rejected with an error. - capability: (optional) the capability to associate with the access token. If none is specified, a token will be requested with all of the capabilities of the specified key. - clientId: (optional) a client Id to associate with the token - timestamp: (optional) the time in ms since the epoch. If none is specified, the system will be queried for a time value to use. - queryTime (optional) boolean indicating that the Ably system should be queried for the current time when none is specified explicitly.

Throws:

AblyException

authorise

@Deprecated
public Auth.TokenDetails authorise(Auth.TokenParams params,
                                   Auth.AuthOptions options)
                            throws AblyException

Deprecated.

Alias of authorize() (0.9 RSA10l)

Throws:

AblyException

requestToken

public Auth.TokenDetails requestToken(Auth.TokenParams params,
                                      Auth.AuthOptions tokenOptions)
                               throws AblyException

Make a token request. This will make a token request now, even if the library already has a valid token. It would typically be used to issue tokens for use by other clients.

Parameters:

params - : see authorize(io.ably.lib.rest.Auth.TokenParams, io.ably.lib.rest.Auth.AuthOptions) for params

tokenOptions - : see authorize(io.ably.lib.rest.Auth.TokenParams, io.ably.lib.rest.Auth.AuthOptions) for options

Throws:

AblyException

createTokenRequest

public Auth.TokenRequest createTokenRequest(Auth.TokenParams params,
                                            Auth.AuthOptions options)
                                     throws AblyException

Create a signed token request based on known credentials and the given token params. This would typically be used if creating signed requests for submission by another client.

Parameters:

params - : see authorize(io.ably.lib.rest.Auth.TokenParams, io.ably.lib.rest.Auth.AuthOptions) for params

options - : see authorize(io.ably.lib.rest.Auth.TokenParams, io.ably.lib.rest.Auth.AuthOptions) for options

Throws:

public Auth.AuthMethod getAuthMethod()

Get the authentication method for this library instance.

Returns:

getBasicCredentials

public java.lang.String getBasicCredentials()

Get the credentials for HTTP basic auth, if available.

Returns:

Get (a copy of) auth options currently set in this Auth.

renew

public Auth.TokenDetails renew()
                        throws AblyException

Renew auth credentials. Will obtain a new token, even if we already have an apparently valid one. Authorization will use the parameters supplied on construction.

setClientId

public void setClientId(java.lang.String clientId)
                 throws AblyException

Parameters:

clientId -

Throws:

AblyException

checkClientId

public java.lang.String checkClientId(BaseMessage msg,
                                      boolean allowNullClientId,

Verify that a message, possibly containing a clientId, is compatible with Auth.clientId if it is set

Parameters:

msg -

allowNullClientId - : true if it is ok for there to be no resolved clientId

Returns:

the resolved clientId

Throws:

AblyException

serverTimestamp

public long serverTimestamp()

Using time delta obtained before guess current server time

clearCachedServerTime
