NAME

       APR::Request - wrapper for libapreq2's module/handle API.

SYNOPSIS

         use APR::Request;

         $req = APR::Request::Custom->handle($pool,
                                             "foo=arg1&bar=arg2",
                                             "apache=quux",
                                              $parser, 1e6, $bb);
         $param = $req->param("foo");
         $cookie = $req->jar("apache");

DESCRIPTION

       The "APR::Request" module provides the base methods for interfacing with libapreq2's
       module API.  It also provides a few utility functions and constants.

       This manpage documents version 2.13 of the APR::Request, APR::Request::Custom,
       APR::Request::Cookie::Table, and APR::Request::Param::Table packages.

METHODS

       APR::Request::Custom - derived from APR::Request.

   handle
           APR::Request::Custom->handle($pool,
                                        $query_string,
                                        $cookie_header,
                                        $parser,
                                        $read_limit,
                                        $brigade)

       Creates a new APR::Request::Custom object.  The $query_string and $cookie_headers are
       immediately parsed into the "args" and "jar" tables.  The $parser is an
       APR::Request::Parser object which is invoked when fetching "body" entries from the
       $brigade.  The $read_limit represents the maximum number of bytes this handle may feed
       into the parser.

METHODS

       APR::Request

   pool
           $req->pool()

       Returns the APR::Pool object associated to this handle.

   bucket_alloc
           $req->bucket_alloc()

       Returns the APR::BucketAlloc object associated to this handle.

   jar_status
           $req->jar_status()

       Returns the final status code of the handle's cookie header parser.

   args_status
           $req->args_status()

       Returns the final status code of the handle's query-string parser.

   body_status
           $req->body_status()

       Returns the final status code of the handle's body parser.

   param_status
           $req->param_status()

       Returns "($req->args_status, $req->body_status)" in list context; otherwise returns
       "$req->args_status || $req->body_status".

   parse
           $req->parse()

       Parses the jar, args, and body tables. Returns "$req->jar_status, $req->args_status,
       $req->body_status".

           @status = $req->parse;
           ok @status == 3;
           ok $status[0] == $req->jar_status;
           ok $status[1] == $req->args_status;
           ok $status[2] == $req->body_status;

   jar
           $req->jar()
           $req->jar($key)

       With no arguments, this method returns a tied APR::Request::Cookie::Table object (or undef
       if the "Cookie" header is absent) in scalar context, or the names (in order, with
       repetitions) of all the parsed cookies.

       With the $key argument, in scalar context this method fetches the first matching cookie.
       In list context it returns all matching cookies.  The returned cookies are the values as
       they appeared in the incoming Cookie header.

       jar() will throw an APR::Request::Error object whenever jar_status() is non-zero and the
       return value is potentially invalid (eg "scalar $req->jar($key)" will not die if the
       desired cookie was successfully parsed).

           $jar = $req->jar;
           @cookie_names = $req->jar;
           ok $jar->isa("APR::Request::Cookie::Table");
           ok shift @cookie_names eq $_ for keys %$jar;

           $cookie = $req->jar("apache");
           @cookies = $req->jar("apache");

   args
           $req->args()
           $req->args($key)

       With no arguments, this method returns a tied APR::Request::Param::Table object (or undef
       if the query string is absent) in scalar context, or the names (in order, with
       repetitions) of all the parsed query-string arguments.

       With the $key argument, in scalar context this method fetches the first matching query-
       string arg.  In list context it returns all matching args.

       args() will throw an APR::Request::Error object whenever args_status() is non-zero and the
       return value is potentially invalid (eg "scalar $req->args($key)" will not die if the
       desired query argument was successfully parsed).

          $args = $req->args;
          @arg_names = $req->args;
          ok $args->isa("APR::Request::Param::Table");
          ok shift @arg_names eq $_ for keys %$args;

          $foo = $req->args("foo");
          @bar = $req->args("bar");

   body
           $req->body()
           $req->body($key)

       With no arguments, this method returns a tied APR::Request::Param::Table object (or undef
       if the request body is absent) in scalar context, or the names (in order, with
       repetitions) of all the parsed cookies.

       With the $key argument, in scalar context this method fetches the first matching body
       param.  In list context it returns all matching body params.

       body() will throw an APR::Request::Error object whenever body_status() is non-zero and the
       return value is potentially invalid (eg "scalar $req->body($key)" will not die if the
       desired body param was successfully parsed).

           $body = $req->body;
           @body_names = $req->body;
           ok $body->isa("APR::Request::Param::Table");
           ok shift @body_names eq $_ for keys %$body;

           $alpha = $req->body("alpha");
           @beta = $req->body("beta");

   param
           $req->param()
           $req->param($key)

       With no arguments, this method returns a tied APR::Request::Param::Table object (or undef,
       if the query string and request body are absent) in scalar context, or the names (in
       order, with repetitions) of all the incoming (args + body) params.

       With the $key argument, in scalar context this method fetches the first matching param.
       In list context it returns all matching params.

       param() will throw an APR::Request::Error object whenever param_status() is non-zero and
       the return value is potentially invalid (eg "scalar $req->param($key)" will not die if the
       desired param was successfully parsed).

           $param = $req->param;
           @param_names = $req->param;
           ok $param->isa("APR::Request::Param::Table");
           ok shift @param_names eq $_ for keys %$param;

           $foo = $req->param("foo");
           @foo = $req->param("foo");

   upload
           $req->upload()
           $req->upload($key)

       With no arguments, this method returns a tied APR::Request::Param::Table object (or undef
       if the request body is absent) in scalar context (whose entries are APR::Request::Param
       objects), or the names (in order, with repetitions) of all the incoming uploads.

       With the $key argument, in scalar context this method fetches the first matching upload.
       In list context it returns all matching uploads.  The return values are
       APR::Request::Param objects.

       upload() will throw an APR::Request::Error object whenever body_status() is non-zero.

           $uploads = $req->upload;
           @upload_names = $req->upload;
           ok $uploads->isa("APR::Request::Param::Table");
           ok shift @upload_names eq $_ for keys %$uploads;
           ok $_->upload for values %$uploads;

           $up = $req->upload("beta");
           @ups = $req->upload("beta");
           ok $_->isa("APR::Request::Param") for $up, @ups;
           ok $_->upload for $up, @ups;

   read_limit
           $req->read_limit()
           $req->read_limit($set)

       Get/set the read limit, which controls the total amount of bytes that can be fed to the
       current parser.

   brigade_limit
           $req->brigade_limit()
           $req->brigade_limit($set)

       Get/set the brigade_limit for the current parser.  This limit determines how many bytes of
       a file upload that the parser may spool into main memory.  Uploads exceeding this limit
       are written directly to disk.

   temp_dir
           $req->temp_dir()
           $req->temp_dir($set)

       Get/set the spool directory for uploads which exceed the configured brigade_limit.

   disable_uploads
           $req->disable_uploads()

       Engage the disable_uploads hook for this request.

   upload_hook
           $req->upload_hook($callback)

       Add an upload hook callback for this request.  The arguments to the $callback sub are
       ($upload, $new_data).

   import
       Exports a list of subs into the caller's package.

SUBROUTINES

       APR::Request

   encode
           encode($string)

       Exportable sub which returns the url-encoded form of $string.

   decode
           decode($string)

       Exportable sub which returns the url-decoded form of $string.

SUBCLASSING

       APR::Request

       If the instances of your subclass are hash references then you can actually inherit from
       APR::Request as long as the APR::Request object is stored in an attribute called "r" or
       "_r". (The APR::Request class effectively does the delegation for you automagically, as
       long as it knows where to find the APR::Request object to delegate to.)  For example:

               package MySubClass;
               use APR::Request::Custom;
               our @ISA = qw(APR::Request);
               sub new {
                   my($class, @args) = @_;
                   return bless { r => APR::Request::Custom->handle(@args) }, $class;
               }

METHODS

         APR::Request::Cookie::Table - read-only version of APR::Table.

       Tables in this class normally arise from calls to "APR::Request::jar()".

   cookie_class
           $table->cookie_class()
           $table->cookie_class($set)

       Get/set the class each table element is blessed into during a get or FETCH call.  If
       defined, the class must be derived from APR::Request::Cookie.  When called with $set, it
       returns the $table.  Otherwise it returns the name of the current class, or undef if no
       cookie class is defined.

   get
           $table->get($key)

       Same as FETCH.

   FETCH
           $table->FETCH($key)

       In scalar context, this returns the first value matching $key (note: see NEXTKEY for
       additional notes).  The match is always case-insensitive.  In list context, this returns
       all matching values.  Note: the type of the return values depends on the table's current
       cookie_class.

   EXISTS
       Synonym for "defined"; these tables are not allowed to contain undefined values. Since
       these are constant tables, they don't autovivify either.

   FIRSTKEY
           $table->FIRSTKEY()

       Returns the first key in the table.

   NEXTKEY
           $table->NEXTKEY()

       Returns the next key in the table.  For perl 5.8+, if the key is multivalued, a subsequent
       FETCH on this key will return the corresponding value, until either NEXTKEY or FIRSTKEY is
       invoked again.  For perl 5.6, FETCH always returns the first value.

   do
           $table->do($callback, @keys)

       Same as APR::Table::do; iterates over the table calling $callback->($key, $value) for each
       matching @keys.  If @keys is empty, this iterates over the entire table.

       Note: The type of $value inserted into the callback depends on the table's current
       cookie_class.

METHODS

       APR::Request::Param::Table

   param_class
           $table->param_class()
           $table->param_class($set)

       Get/set the class each table element is blessed into during a "get" or "FETCH" call.  If
       defined, the class must be derived from APR::Request::Param.  When called with $set, it
       returns the $table.  Otherwise it returns the name of the current class, or undef if no
       param class is defined.

   get
           $table->get($key)

       Same as FETCH.

   FETCH
           $table->FETCH($key)

       In scalar context, this returns the first value matching $key (see NEXTKEY for additional
       notes on this).  The match is always case-insensitive.  In list context, this returns all
       matching values.  Note: the type of the return values depends on the table's current
       param_class.

   EXISTS
       Synonym for "defined"; these tables are not allowed to contain undefined values. Since
       these are constant tables, they don't autovivify either.

   NEXTKEY
           $table->NEXTKEY()

       Returns the next key in the table.  For perl 5.8+, if the key is multivalued, a subsequent
       FETCH on this key will return the corresponding value, until either NEXTKEY or FIRSTKEY is
       invoked again.  For perl 5.6, FETCH always returns the first value.

   FIRSTKEY
           $table->FIRSTKEY()

       Returns the first key in the table.

   do
           $table->do($callback, @keys)

       Same as APR::Table::do; iterates over the table calling $callback->($key, $value) for each
       matching @keys.  If @keys is empty, this iterates over the entire table.

       Note: The type of $value inserted into the callback depends on the table's current
       value_class.
