Detailed Description

this class supports the implementation of HTTP file-based request handler with automatic handling of files in a certain root directory as well as rendering of templates

Member Function Documentation

◆ constructor()

OMQ::ServiceFileHandler::constructor ( string  file_root,
string  url_root,
*hash< auto >  opt 
)

create the object optionally with the given AbstractAuthenticator

Parameters
file_rootthe filesystem root directory for serving files
url_rootthe root part of the URL path without the leading "/"
optan optional with one or more of the following option keys:
  • default_target: the default relative path to use if a request cannot be satisfied
  • po: the Program parse options for the template file programs
  • psetup: an optional closure or call reference taking a single Program argument to be called when initializing template programs to set up a custom template API, etc
  • auth: the authentication object to use to authenticate connections (see AbstractAuthenticator); if no AbstractAuthenticator object is passed, then by default the system RBAC authenticator is used; meaning that Qorus application users are required to connect, and the users must have the OMQ::QR_LOGIN role to connect as well
  • error_level: the level of error reporting (0, 1, or 2)
