http_wrapper(:Goal,
+In, +Out, -Connection, +Options)’Keep-alive’ if both ends of the connection
want to continue the connection or close if either side
wishes to close the connection.
This predicate reads an HTTP request-header from In,
redirects current output to a memory file and then runs call(Goal,
Request), watching for exceptions and failure. If Goal
executes successfully it generates a complete reply from the created
output. Otherwise it generates an HTTP server error with additional
context information derived from the exception.
http_wrapper/5 supports the following options:
- request(-Request)
- Return the executed request to the caller.
- peer(+Peer)
- Add peer(Peer) to the request header handed to Goal. The format of Peer is defined by tcp_accept/3 from the clib package.
