Method Detail

init

public void init(Map<String,Object> pluginConfig)

Description copied from class: AuthenticationPlugin

This is called upon loading up of a plugin, used for setting it up.

Specified by:

init in class AuthenticationPlugin

Parameters:

pluginConfig - Config parameters, possibly from a ZK source

getInitFilterConfig

protected javax.servlet.FilterConfig getInitFilterConfig(Map<String,Object> pluginConfig,
                                                         boolean skipKerberosChecking)

doAuthenticate

public boolean doAuthenticate(javax.servlet.ServletRequest req,
                              javax.servlet.ServletResponse rsp,
                              javax.servlet.FilterChain chain)
                       throws Exception

Description copied from class: AuthenticationPlugin

This method attempts to authenticate the request. Upon a successful authentication, this must call the next filter in the filter chain and set the user principal of the request, or else, upon an error or an authentication failure, throw an exception.

Specified by:

doAuthenticate in class AuthenticationPlugin

Parameters:

req - the http request

rsp - the http response

chain - the servlet filter chain

Returns:

false if the request not be processed by Solr (not continue), i.e. the response and status code have already been sent.

Throws:

Exception - any exception thrown during the authentication, e.g. PrivilegedActionException

interceptInternodeRequest

protected boolean interceptInternodeRequest(org.apache.http.HttpRequest httpRequest,
                                            org.apache.http.protocol.HttpContext httpContext)

Description copied from class: AuthenticationPlugin

Override this method to intercept internode requests. This allows your authentication plugin to decide on per-request basis whether it should handle inter-node requests or delegate to PKIAuthenticationPlugin. Return true to indicate that your plugin did handle the request, or false to signal that PKI plugin should handle it. This method will be called by PKIAuthenticationPlugin's interceptor.

If not overridden, this method will return true for plugins implementing HttpClientBuilderPlugin. This method can be overridden by subclasses e.g. to set HTTP headers, even if you don't use a clientBuilder.

Overrides:

interceptInternodeRequest in class AuthenticationPlugin

Parameters:

httpRequest - the httpRequest that is about to be sent to another internal Solr node

httpContext - the context of that request.

Returns:

true if this plugin handled authentication for the request, else false

getHttpClientBuilder

public SolrHttpClientBuilder getHttpClientBuilder(SolrHttpClientBuilder builder)

Specified by:

getHttpClientBuilder in interface HttpClientBuilderPlugin

Returns:

Returns an instance of a SolrHttpClientBuilder to be used for configuring the HttpClients for use with SolrJ clients.

setup

public void setup(Http2SolrClient client)

Specified by:

setup in interface HttpClientBuilderPlugin

close

public void close()

Description copied from interface: SolrMetricProducer

Implementations should always call SolrMetricProducer.super.close() to ensure that metrics with the same life-cycle as this component are properly unregistered. This prevents obscure memory leaks.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface SolrMetricProducer

getKerberosFilter

protected javax.servlet.Filter getKerberosFilter()

setKerberosFilter

protected void setKerberosFilter(javax.servlet.Filter kerberosFilter)
