proxyAddress

public SingleAddressHttpClientBuilder<U,R> proxyAddress(U proxyAddress)

Description copied from interface: SingleAddressHttpClientBuilder

Configures a proxy to serve as an intermediary for requests.

If the client talks to a proxy over http (not https, ClientSslConfig is NOT configured), it will rewrite the request-target to absolute-form, as specified by the RFC.

For secure proxy tunnels (when ClientSslConfig is configured) the tunnel is always initialized using HTTP/1.1 CONNECT request. The actual protocol will be negotiated via ALPN extension of TLS protocol, taking into account HTTP protocols configured via SingleAddressHttpClientBuilder.protocols(HttpProtocolConfig...) method. In case of any error during CONNECT process, ProxyConnectException or ProxyConnectResponseException will be thrown when a request attempt is made through the constructed client instance.

Specified by:

proxyAddress in interface SingleAddressHttpClientBuilder<U,R>

Parameters:

proxyAddress - Unresolved address of the proxy. When used with a builder created for a resolved address, proxyAddress should also be already resolved – otherwise runtime exceptions may occur.

Returns:

this.

proxyConfig

appendConnectionFilter

public SingleAddressHttpClientBuilder<U,R> appendConnectionFilter(StreamingHttpConnectionFilterFactory factory)

Description copied from interface: SingleAddressHttpClientBuilder

Appends the filter to the chain of filters used to decorate the StreamingHttpConnection created by this builder.

Filtering allows you to wrap a StreamingHttpConnection and modify behavior during request/response processing Some potential candidates for filtering include logging, metrics, and decorating responses.

The order of execution of these filters are in order of append. If 3 filters are added as follows:

     builder.appendConnectionFilter(filter1).appendConnectionFilter(filter2).appendConnectionFilter(filter3)
 

making a request to a connection wrapped by this filter chain the order of invocation of these filters will be:

     filter1 ⇒ filter2 ⇒ filter3 ⇒ connection
 

Specified by:

appendConnectionFilter in interface SingleAddressHttpClientBuilder<U,R>

Parameters:

factory - StreamingHttpConnectionFilterFactory to decorate a StreamingHttpConnection for the purpose of filtering.

Returns:

this

appendConnectionFilter

public SingleAddressHttpClientBuilder<U,R> appendConnectionFilter(Predicate<StreamingHttpRequest> predicate,
 StreamingHttpConnectionFilterFactory factory)

Description copied from interface: SingleAddressHttpClientBuilder

Appends the filter to the chain of filters used to decorate the StreamingHttpConnection created by this builder, for every request that passes the provided Predicate.

Filtering allows you to wrap a StreamingHttpConnection and modify behavior during request/response processing Some potential candidates for filtering include logging, metrics, and decorating responses.

The order of execution of these filters are in order of append. If 3 filters are added as follows:

     builder.appendConnectionFilter(filter1).appendConnectionFilter(filter2).appendConnectionFilter(filter3)
 

making a request to a connection wrapped by this filter chain the order of invocation of these filters will be:

When overriding this method, delegate to super as it uses internal utilities to provide a consistent execution flow.

Specified by:

appendConnectionFilter in interface SingleAddressHttpClientBuilder<U,R>

Parameters:

predicate - the Predicate to test if the filter must be applied.

factory - StreamingHttpConnectionFilterFactory to decorate a StreamingHttpConnection for the purpose of filtering.

Returns:

this

ioExecutor

public SingleAddressHttpClientBuilder<U,R> ioExecutor(IoExecutor ioExecutor)

Specified by:

ioExecutor in interface SingleAddressHttpClientBuilder<U,R>

executor

public SingleAddressHttpClientBuilder<U,R> executor(Executor executor)

Specified by:

executor in interface SingleAddressHttpClientBuilder<U,R>

executionStrategy

public SingleAddressHttpClientBuilder<U,R> executionStrategy(HttpExecutionStrategy strategy)

Description copied from interface: SingleAddressHttpClientBuilder

Sets the HttpExecutionStrategy to be used for client callbacks when executing client requests for all clients created from this builder.

Specifying an execution strategy affects the offloading used during execution of client requests:

Unspecified or HttpExecutionStrategies.defaultStrategy()

Execution of client requests will use a safe (non-blocking) execution strategy appropriate for the client API used and the filters added. Blocking is always safe as all potentially blocking paths are offloaded. Each client API variant (async/blocking streaming/aggregate) requires a specific execution strategy to avoid blocking the event-loop and filters added via SingleAddressHttpClientBuilder.appendClientFilter(StreamingHttpClientFilterFactory), SingleAddressHttpClientBuilder.appendConnectionFilter(StreamingHttpConnectionFilterFactory), or SingleAddressHttpClientBuilder.appendConnectionFactoryFilter(ConnectionFactoryFilter), etc. may also require offloading. The execution strategy for execution of client requests will be computed based on the client API in use and HttpExecutionStrategyInfluencer.requiredOffloads() of added the filters.

HttpExecutionStrategies.offloadNone() (or deprecated HttpExecutionStrategies.offloadNever())

No offloading will be used during execution of client requests regardless of the client API used or the influence of added filters. Filters and asynchronous callbacks must not ever block during the execution of client requests.

A custom execution strategy (HttpExecutionStrategies.customStrategyBuilder()) or HttpExecutionStrategies.offloadAll()

The specified execution strategy will be used for executing client requests rather than the client API's default safe strategy. Like with the default strategy, the actual execution strategy used is computed from the provided strategy and the execution strategies required by added filters. Filters and asynchronous callbacks MAY only block during the offloaded portions of the client request execution.

Specified by:

executionStrategy in interface SingleAddressHttpClientBuilder<U,R>

Parameters:

strategy - HttpExecutionStrategy to use. If callbacks to the application code may block then those callbacks must request to be offloaded.

Returns:

this.

appendConnectionFactoryFilter

public SingleAddressHttpClientBuilder<U,R> appendConnectionFactoryFilter(ConnectionFactoryFilter<R,FilterableStreamingHttpConnection> factory)

Description copied from interface: SingleAddressHttpClientBuilder

Appends the filter to the chain of filters used to decorate the ConnectionFactory used by this builder.

Filtering allows you to wrap a ConnectionFactory and modify behavior of ConnectionFactory.newConnection(Object, ContextMap, TransportObserver). Some potential candidates for filtering include logging and metrics.

The order of execution of these filters are in order of append. If 3 filters are added as follows:

     builder
         .appendConnectionFactoryFilter(filter1)
         .appendConnectionFactoryFilter(filter2)
         .appendConnectionFactoryFilter(filter3)

     filter1 ⇒ filter2 ⇒ filter3 ⇒ original connection factory
 

Specified by:

appendConnectionFactoryFilter in interface SingleAddressHttpClientBuilder<U,R>

Parameters:

factory - ConnectionFactoryFilter to use.

Returns:

this
