- io.ably.lib.rest.Auth.AuthOptions

Direct Known Subclasses:

ClientOptions

Enclosing class:

Auth
```
public static class Auth.AuthOptions
extends java.lang.Object
```
Passes authentication-specific properties in authentication requests to Ably. Properties set using AuthOptions are used instead of the default values set when the client library is instantiated, as opposed to being merged with them.

Field Summary

Fields
Modifier and Type	Field	Description
`Auth.TokenCallback`	`authCallback`	Called when a new token is required.
`Param[]`	`authHeaders`	A set of key-value pair headers to be added to any request made to the authUrl.
`java.lang.String`	`authMethod`	The HTTP verb to use for any request made to the authUrl, either GET or POST.
`Param[]`	`authParams`	A set of key-value pair params to be added to any request made to the authUrl.
`java.lang.String`	`authUrl`	A URL that the library may use to obtain a token string (in plain text format), or a signed `Auth.TokenRequest` or `Auth.TokenDetails` (in JSON format) from.
`java.lang.String`	`key`	The full API key string, as obtained from the Ably dashboard.
`boolean`	`queryTime`	If true, the library queries the Ably servers for the current time when issuing `Auth.TokenRequest` instead of relying on a locally-available time of day.
`java.lang.String`	`token`	An authenticated token.
`Auth.TokenDetails`	`tokenDetails`	An authenticated `Auth.TokenDetails` object (most commonly obtained from an Ably Token Request response).
`boolean`	`useTokenAuth`	When true, forces token authentication to be used by the library.

- Field Detail
  - authCallback
```
public Auth.TokenCallback authCallback
```
    Called when a new token is required. The role of the callback is to obtain a fresh token, one of: an Ably Token string (in plain text format); a signed Auth.TokenRequest; a Auth.TokenDetails (in JSON format); an Ably JWT. See the authentication documentation for details of the Ably Auth.TokenRequest format and associated API calls.
    This callback is invoked on a background thread.
    Spec: RSA4a, RSA4, TO3j5, AO2b
  - authUrl
```
public java.lang.String authUrl
```
    A URL that the library may use to obtain a token string (in plain text format), or a signed Auth.TokenRequest or Auth.TokenDetails (in JSON format) from.
    Spec: RSA4a, RSA4, RSA8c, TO3j6, AO2c
  - authMethod
```
public java.lang.String authMethod
```
    The HTTP verb to use for any request made to the authUrl, either GET or POST. The default value is GET.
    Spec: RSA8c, TO3j7, AO2d
  - key
```
public java.lang.String key
```
    The full API key string, as obtained from the Ably dashboard. Use this option if you wish to use Basic authentication, or wish to be able to issue Ably Tokens without needing to defer to a separate entity to sign Ably Auth.TokenRequest. Read more about Basic authentication.
    Spec: RSA11, RSA14, TO3j1, AO2a
  - token
```
public java.lang.String token
```
    An authenticated token. This can either be a Auth.TokenDetails object, a Auth.TokenRequest object, or token string (obtained from the token property of a Auth.TokenDetails component of an Ably Auth.TokenRequest response, or a JSON Web Token satisfying the Ably requirements for JWTs). This option is mostly useful for testing: since tokens are short-lived, in production you almost always want to use an authentication method that enables the client library to renew the token automatically when the previous one expires, such as authUrl or authCallback. Read more about Token authentication.
    Spec: RSA4a, RSA4, TO3j2
  - tokenDetails
```
public Auth.TokenDetails tokenDetails
```
    An authenticated Auth.TokenDetails object (most commonly obtained from an Ably Token Request response). This option is mostly useful for testing: since tokens are short-lived, in production you almost always want to use an authentication method that enables the client library to renew the token automatically when the previous one expires, such as authUrl or authCallback. Use this option if you wish to use Token authentication. Read more about Token authentication.
    Spec: RSA4a, RSA4, TO3j2
  - authHeaders
```
public Param[] authHeaders
```
    A set of key-value pair headers to be added to any request made to the authUrl. Useful when an application requires these to be added to validate the request or implement the response. If the authHeaders object contains an authorization key, then withCredentials is set on the XHR request.
    Spec: RSA8c3, TO3j8, AO2e
  - authParams
```
public Param[] authParams
```
    A set of key-value pair params to be added to any request made to the authUrl. When the authMethod is GET, query params are added to the URL, whereas when authMethod is POST, the params are sent as URL encoded form data. Useful when an application requires these to be added to validate the request or implement the response.
    Spec: RSA8c3, RSA8c1, TO3j9, AO2f
  - queryTime
```
public boolean queryTime
```
    If true, the library queries the Ably servers for the current time when issuing Auth.TokenRequest instead of relying on a locally-available time of day. Knowing the time accurately is needed to create valid signed Ably Auth.TokenRequest, so this option is useful for library instances on auth servers where for some reason the server clock cannot be kept synchronized through normal means, such as an NTP daemon. The server is queried for the current time once per client library instance (which stores the offset from the local clock), so if using this option you should avoid instancing a new version of the library for each request. The default is false.
    Spec: RSA9d, TO3j10, AO2a
  - useTokenAuth
```
public boolean useTokenAuth
```
    When true, forces token authentication to be used by the library. If a clientId is not specified in the ClientOptions or Auth.TokenParams, then the Ably Token issued is anonymous.
    Spec: RSA4, RSA14, TO3j4
