Method Detail

doRedirect

public rx.Observable<HttpClientResponse<O>> doRedirect(RedirectOperator.RedirectHandler.RedirectionContext context,
                                                       HttpClientRequest<I> originalRequest,
                                                       HttpClient.HttpClientConfig config)

Description copied from interface: RedirectOperator.RedirectHandler

Performs the redirect operation. This should at the least call RedirectOperator.RedirectHandler.RedirectionContext.newLocation(String) with the new redirect location.

Specified by:

doRedirect in interface RedirectOperator.RedirectHandler<I,O>

Parameters:

context - Redirection context.

originalRequest - Original request that started this response processing.

config - Client config to use while making the redirect request.

Returns:

The response after executing the redirect.

redirect

protected rx.Observable<HttpClientResponse<O>> redirect(HttpClientRequest<I> redirectRequest,
                                                        HttpClient.HttpClientConfig config)

requiresRedirect

public boolean requiresRedirect(RedirectOperator.RedirectHandler.RedirectionContext context,
                                HttpClientResponse<O> response)

Description copied from interface: RedirectOperator.RedirectHandler

Asserts whether the passed response requires a redirect. If this returns true then RedirectOperator.RedirectHandler.doRedirect(RedirectionContext, HttpClientRequest, HttpClient.HttpClientConfig) will be called for this response if and only if the redirect is valid specified by RedirectOperator.RedirectHandler.validate(RedirectionContext, HttpClientResponse)

Specified by:

requiresRedirect in interface RedirectOperator.RedirectHandler<I,O>

Parameters:

context - Redirection context.

response - The response to be evaluated for redirects.

Returns:

true if the response needs redirection, else false

validate

public void validate(RedirectOperator.RedirectHandler.RedirectionContext context,
                     HttpClientResponse<O> redirectResponse)

Description copied from interface: RedirectOperator.RedirectHandler

This is invoked if a particular response requires a redirect as evaluated by RedirectOperator.RedirectHandler.requiresRedirect(RedirectionContext, HttpClientResponse). If this returns false the redirect is not performed, instead an error is propagated.

This should throw an exception if the redirect is not valid. eg: If the max redirects limit is 3 and the redirects till now are 2, then this method should thrown an exception.

Specified by:

validate in interface RedirectOperator.RedirectHandler<I,O>

Parameters:

context - The redirection context.

redirectResponse - The response to be evaluated for redirects.

extractRedirectLocation

protected java.lang.String extractRedirectLocation(HttpClientResponse<O> redirectedResponse)

createRedirectRequest

protected HttpClientRequest<I> createRedirectRequest(HttpClientRequest<I> original,
                                                     java.net.URI redirectLocation,
                                                     int redirectStatus)

getNettyRequestUri

protected static java.lang.String getNettyRequestUri(java.net.URI uri,
                                                     java.lang.String originalUriString,
                                                     int redirectStatus)
