Request(3) User Contributed Perl Documentation Request(3)NAMEAPR::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.
METHODSAPR::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, $new_data).
import
Exports a list of subs into the caller's package.
SUBROUTINESAPR::Request
encode
encode($string)
Exportable sub which returns the url-encoded form of $string.
decode
decode($string)
Exportable sub which returns the url-decoded form of $string.
SUBCLASSINGAPR::Request
If the instances of your subclass are hash references then you can
actually inherit from APR::Request as long as the APR::Request object
is stored in an attribute called "r" or "_r". (The APR::Request class
effectively does the delegation for you automagically, as long as it
knows where to find the APR::Request object to delegate to.) For
example:
package MySubClass;
use APR::Request::Custom;
our @ISA = qw(APR::Request);
sub new {
my($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.
