# HttpRequest 

###
Companion object HttpRequest

#### class HttpRequest[T] extends AnyRef

A client-side HTTP request.

Instances are created by an io.vertx.scala.ext.web.client.WebClient instance, via one of the methods corresponding to the specific HTTP methods such as io.vertx.scala.ext.web.client.WebClient#get, etc...

The request shall be configured prior sending, the request is immutable and when a mutator method is called, a new request is returned allowing to expose the request in a public API and apply further customization.

After the request has been configured, the methods

- io.vertx.scala.ext.web.client.HttpRequest#send
- io.vertx.scala.ext.web.client.HttpRequest#sendStream
- io.vertx.scala.ext.web.client.HttpRequest#sendJson ()}
- io.vertx.scala.ext.web.client.HttpRequest#sendForm

can be called. The `sendXXX` methods perform the actual request, they can be called multiple times to perform the same HTTP request at different points in time.

The handler is called back with

- an io.vertx.scala.ext.web.client.HttpResponse instance when the HTTP response has been received
- a failure when the HTTP request failed (like a connection error) or when the HTTP response could not be obtained (like connection or unmarshalling errors)

Most of the time, this client will buffer the HTTP response fully unless a specific is used such as .
