Add a header to these headers. The header should be a type with a recurring Header instance to ensure that the new value can be appended to any existing values.

>>> import org.http4s.headers.Accept

>>> val req = Request().addHeader(Accept(MediaRange.`application/*`))
>>> req.headers.get[Accept]
Some(Accept(NonEmptyList(application/*)))

>>> val req2 = req.addHeader(Accept(MediaRange.`text/*`))
>>> req2.headers.get[Accept]
Some(Accept(NonEmptyList(application/*, text/*)))

cURL representation of the request.

Supported cURL-Parameters are: --request, --url, --header. Note that asCurl will not print the request body.

Parses all available org.http4s.headers.Cookie headers into a list of RequestCookie objects. This implementation is compatible with cookie headers formatted per HTTP/1 and HTTP/2, or even both at the same time.

Lifts this Message's body to the specified effect type.

Helper method for decoding Requests

Attempt to decode the Request and, if successful, execute the continuation to get a Response. If decoding fails, an UnprocessableEntity Response is generated.

Helper method for decoding Requests

Attempt to decode the Request and, if successful, execute the continuation to get a Response. If decoding fails, an UnprocessableEntity Response is generated. If the decoder does not support the MediaType of the Request, a UnsupportedMediaType Response is generated instead.

Keep headers that satisfy the predicate

Checks whether the Entity of the Message is pure in the sense of indicating that the entity body can be re-run without side effects.

Representation of the query string as a map

In case a parameter is available in query string but no value is there the list will be empty. If the value is empty the the list contains an empty string.

Examples

The query string is lazily parsed. If an error occurs during parsing an empty Map is returned.

View of the head elements of the URI parameters in query string.

In case a parameter has no value the map returns an empty string.

Add the provided headers to the existing headers, replacing those of the same header name

>>> import org.http4s.headers.Accept

>>> val req = Request().putHeaders(Accept(MediaRange.`application/*`))
>>> req.headers.get[Accept]
Some(Accept(NonEmptyList(application/*)))

>>> val req2 = req.putHeaders(Accept(MediaRange.`text/*`))
>>> req2.headers.get[Accept]
Some(Accept(NonEmptyList(text/*)))

Compiles the body stream to a single chunk and sets it as the body. Replaces any Transfer-Encoding: chunked with a Content-Length header. It is the caller's responsibility to assure there is enough memory to materialize the entity body and control the time limits of that materialization.

The trailer headers, as specified in Section 3.6.1 of RFC 2616. The resulting F might not complete until the entire body has been consumed.

Generates a new message object with the specified key/value pair appended to the attributes.

Sets the entity body without affecting headers such as Transfer-Encoding or Content-Length. Most use cases are better served by withEntity[F1[x]](entity*, which uses an EntityEncoder to maintain the headers.

WARNING: this method does not modify the headers of the message, and as a consequence headers may be incoherent with the body.

Set an Entity.Empty entity on this message, and remove all payload headers that make no sense with an empty body.

Replace the body of this message with a new body

Returns a new message object without the specified key in the attributes.
