fix#581
* request and response headers now have convenience
constructors so important fields like method, target,
result, and version may be set upon construction.
Actions Required:
* Evaluate each message constructor call site and
adjust the constructor argument list as needed.
Actions Required:
* Change calls to msg.prepare to msg.prepare_payload. For messages
with a user-defined Fields, provide the function prepare_payload_impl
in the fields type according to the Fields requirements.
* FieldsReader now requires chunked() and keep_alive()
* serializer logic calls into the reader to calculate
the message metadata
* Removed some of the previous requirements of FieldsReader
Actions Required:
* Implement chunked() and keep_alive() for user defined FieldsReader types.
fix#497
This changes the function signature to accept the `value_type`
instead of the entire message.
Actions Required:
* For any user-defined models of Body, change the function signature
to accept `value_type const&` and modify the function definition
accordingly.
* Container interface more closely matches std::vector
* While preserving the invariant that duplicate fields
with the same case-insensitive name have their order
preserved.
* header::result is a family of functions to replace header::status
* header interface now uses status enum and also ints
* reason-phrase is no longer stored unless the user explicitly
requests it.
* When serializing, the standard reason is used for the
corresponding status code unless the user has changed it.
The verb interfaces now use verb::unknown instead of
boost::optional<verb> == boost::none to indicate that
the request-method is an unrecognized string.
The http::header interface is modified to focus more on the
verb enum rather than the string. For recognized verbs, the
implementation stores an integer instead of the string.
Unknown verbs are still stored as strings.
* header::method now returns a verb
* header::method_string returns the method text
fix#398
A new enum status is added for the status code.
The function obsolete_reason returns default reason phrasing.
If a response has an empty reason, the serializer will
automatically insert the default reason phrase for the
status code.
fix#124
The http::header data members "method", "url", and "reason"
are changed from data members, to pairs of get and set
functions which forward the call to the Fields type used
to instantiate the template.
Previously, these data members were implemented using
std::string. With this change, the implementation of the
Fields type used to instantiate the template is now in
control of the representation of those values. This permits
custom memory allocation strategies including uniform use of
the Allocator type already provided to beast::http::basic_fields.
fix#171
Several names and HTTP identifiers are renamed to be
more consistent, self-explanatory, and concise:
* "Fields" is a collection of HTTP header fields (rfc7230 section 3.2)
* "Header" is the Start Line plus Fields. Another way to look at it is,
the HTTP message minus the body.
* `basic_fields` replaces `basic_headers`
* `fields` replaces `headers`
* `Fields` replaces `Headers` in template parameter lists
* `header` replaces `message_headers`
* `header::fields` replaces `message_headers::fields`
The changes are cosmetic and do not affect run-time behavior.
message_headers is now a set of partial class template
specializations instead of a template class alias. This solves
a problem where template functions taking message_headers as a
parameter could not deduce argument types, since std::conditional
obscured the deduced context.
Both classes are refactored to share declarations using an #ifdef,
to eliminate an ugly set of extra declarations needed when building
the documentation.
Copy and move class special members are added.
A new function message::base() is provided which returns the
message_headers portion of a message.
