class HttpClientRequest extends WriteStream[Buffer] with ReadStream[HttpClientResponse]

Represents a client-side HTTP request.

Instances are created by an io.vertx.scala.core.http.HttpClient instance, via one of the methods corresponding to the specific HTTP methods, or the generic request methods. On creation the request will not have been written to the wire.

Once a request has been obtained, headers can be set on it, and data can be written to its body if required. Once you are ready to send the request, one of the io.vertx.scala.core.http.HttpClientRequest#end methods should be called.

Nothing is actually sent until the request has been internally assigned an HTTP connection.

The io.vertx.scala.core.http.HttpClient instance will return an instance of this class immediately, even if there are no HTTP connections available in the pool. Any requests sent before a connection is assigned will be queued internally and actually sent when an HTTP connection becomes available from the pool.

The headers of the request are queued for writing either when the io.vertx.scala.core.http.HttpClientRequest#end method is called, or, when the first part of the body is written, whichever occurs first.

This class supports both chunked and non-chunked HTTP.

It implements io.vertx.scala.core.streams.WriteStream so it can be used with io.vertx.scala.core.streams.Pump to pump data with flow control.

An example of using this class is as follows:

  9. def connectionHandler(handler: Handler[HttpConnection]): HttpClientRequest

    Set a connection handler called when an HTTP connection has been established.

    Set a connection handler called when an HTTP connection has been established. * @param handler the handler

    returns

    a reference to this, so the API can be used fluently

  10. def continueHandler(handler: Handler[Unit]): HttpClientRequest

    If you send an HTTP request with the header Expect set to the value 100-continue and the server responds with an interim HTTP response with a status code of 100 and a continue handler has been set using this method, then the handler will be called.

    If you send an HTTP request with the header Expect set to the value 100-continue and the server responds with an interim HTTP response with a status code of 100 and a continue handler has been set using this method, then the handler will be called.

    You can then continue to write data to the request body and later end it. This is normally used in conjunction with the io.vertx.scala.core.http.HttpClientRequest#sendHead method to force the request header to be written before the request has ended. * @return a reference to this, so the API can be used fluently

  11. def drainHandler(handler: Handler[Unit]): HttpClientRequest

    Set a drain handler on the stream.

    Set a drain handler on the stream. If the write queue is full, then the handler will be called when the write queue is ready to accept buffers again. See io.vertx.scala.core.streams.Pump for an example of this being used.

    The stream implementation defines when the drain handler, for example it could be when the queue size has been reduced to maxSize / 2. * @param handler the handler

    Set's the amount of time after which if the request does not return any data within the timeout period an TimeoutException will be passed to the exception handler (if provided) and the request will be closed.
