Constructor Detail

Builder

public Builder(BasicAuthHttpServiceFilter.CredentialsVerifier<UserInfo> credentialsVerifier,
               java.lang.String realm)

Creates a new builder for an StreamingHttpServiceFilter, which filters HTTP requests using RFC7617: The 'Basic' HTTP Authentication Scheme.

It accepts credentials as user-id:password pairs, encoded using Base64 for Authorization or Proxy-Authorization header values. Use of the format user:password in the userinfo field is deprecated by RFC3986.

User info object of authenticated user could be stored in AsyncContextMap, if AsyncContextMap.Key was configured via userInfoKey(AsyncContextMap.Key).

Note: This scheme is not considered to be a secure method of user authentication unless used in conjunction with some external secure system such as TLS (Transport Layer Security, [RFC5246]), as the user-id and password are passed over the network as cleartext.

Parameters:

credentialsVerifier - a BasicAuthHttpServiceFilter.CredentialsVerifier for user-id and passwords pair

realm - a protection space (realm)

Method Detail

userInfoKey

public BasicAuthHttpServiceFilter.Builder<UserInfo> userInfoKey(AsyncContextMap.Key<UserInfo> userInfoKey)

Sets a key to store a user info object of authenticated user in AsyncContextMap.

Parameters:

userInfoKey - a key to store a user info object in AsyncContextMap

Returns:

this

setCharsetUtf8

public BasicAuthHttpServiceFilter.Builder<UserInfo> setCharsetUtf8(boolean utf8)

Sets an advice for a user agent to use UTF-8 charset when it generates user-id:password pair.

It will result in adding an optional charset="UTF-8" parameter for an authenticate header.

Parameters:

utf8 - if true, an optional charset="UTF-8" parameter will be added for an authenticate header

Returns:

this

buildServer

public StreamingHttpServiceFilterFactory buildServer()

Creates a new instance for non-proxy service.

It will use the following constants to handle authentication:

Response status code, authenticate and authorization headers for non-proxy Basic auth

Response status code	401 (Unauthorized)
Authenticate header	WWW-Authenticate
Authorization header	Authorization

Returns:

a new BasicAuthHttpServiceFilter.Builder

buildProxy

public StreamingHttpServiceFilterFactory buildProxy()

Creates a new instance for proxy service.

It will use the following constants to handle authentication:

Response status code, authenticate and authorization headers for proxy Basic auth

Response status code	407 (Proxy Authentication Required)
Authenticate header	Proxy-Authenticate
Authorization header	Proxy-Authorization

Returns:

a new StreamingHttpServiceFilterFactory
