Apache2::Upload - Methods for dealing with file uploads.

name
           $upload->name()

       The name of the HTML form element which generated the upload.

   filename
           $upload->filename()

       The (client-side) filename as submitted in the HTML form.  Note: some agents will submit the file's full
       pathname, while others may submit just the basename.

   fh
           $upload->fh()

       Creates filehandle reference to the upload's spooled tempfile, which contains the full contents of the
       upload.

   io
           $upload->io()

       Creates a tied IO handle.  This method is a more efficient version of "fh", but with "io" the handle ref
       returned is not seekable.  It is tied to an APR::Request::Brigade object, so you may use the brigade API
       on the tied object if you want to manipulate the IO stream (beyond simply reading from it).

       The returned reference is actually an object which has "read" and "readline" methods available.  However
       these methods are just syntactic sugar for the underlying "READ" and "READLINE" methods from
       APR::Request::Brigade.

           $io = $upload->io;
           print while $io->read($_); # equivalent to: tied(*$io)->READ($_)

       See READ and READLINE below for additional notes on their usage.

   bb
           $upload->bb()
           $upload->bb($set)

       Get/set the APR::Brigade which represents the upload's contents.

   size
           $upload->size()

       Returns the size of the upload in bytes.

   info
           $upload->info()
           $upload->info($set)

       Get/set the additional header information table for the uploaded file.  Returns a hash reference tied to
       the APR::Table class.  An optional $table argument can be passed to reassign the upload's internal
       (apr_table_t) info table to the one $table represents.

           my $info = $upload->info;
           while (my($hdr_name, $hdr_value) = each %$info) {
               # ...
           }

           # fetch upload's Content-Type header
           my $type = $upload->info->{"Content-type"};

   type
           $upload->type()

       Returns the MIME type of the given Apache2::Upload object.

           my $type = $upload->type;

           #same as
           my $content_type = $upload->info->{"Content-Type"};
           $content_type =~ s/;.*$//ms;

   link
           $upload->link()

       To avoid recopying the upload's internal tempfile brigade on a *nix-like system, link will create a hard
       link to it:

         my $upload = $req->upload('foo');
         $upload->link("/path/to/newfile") or
             die sprintf "link from '%s' failed: $!", $upload->tempname;

       Typically the new name must lie on the same device and partition as the brigade's tempfile.  If this or
       any other reason prevents the OS from linking the files, link() will instead copy the temporary file to
       the specified location.

   slurp
           $upload->slurp($contents)

       Reads the full contents of a file upload into the scalar argument.  The return value is the length of the
       file.

           my $size = $upload->slurp($contents);

   tempname
           $upload->tempname()

       Provides the name of the spool file.

           my $tempname = $upload->tempname;

       This class is derived from APR::Brigade, providing additional methods for TIEHANDLE, READ and READLINE.
       To be memory efficient, these methods delete buckets from the brigade as soon as their data is actually
       read, so you cannot "seek" on handles tied to this class.  Such handles have semantics similar to that of
       a read-only socket.

   TIEHANDLE
           APR::Request::Brigade->TIEHANDLE($bb)

       Creates a copy of the bucket brigade represented by $bb, and blesses that copy into the
       APR::Request::Brigade class.  This provides syntactic sugar for using perl's builtin "read", "readline",
       and "<>" operations on handles tied to this package:

           use Symbol;
           $fh = gensym;
           tie *$fh, "APR::Request:Brigade", $bb;
           print while <$fh>;

   READ
           $bb->READ($contents)
           $bb->READ($contents, $length)
           $bb->READ($contents, $length, $offset)

       Reads data from the brigade $bb into $contents.  When omitted $length defaults to -1, which reads the
       first bucket into $contents.  A positive $length will read in $length bytes, or the remainder of the
       brigade, whichever is greater. $offset represents the index in $context to read the new data.

   READLINE
           $bb->READLINE()

       Returns the first line of data from the bride. Lines are terminated by linefeeds (the '\012' character),
       but we may eventually use $/ instead.

perl v5.40.0                                       2024-09-27                               Apache2::Upload(3pm)

       Apache2::Upload is a new module based on the original package included in Apache2::Request 1.X.  Users
       requiring the upload API must now "use Apache2::Upload", which adds the "upload" method to
       Apache2::Request.  Apache2::Upload is largely backwards-compatible with the original 1.X API.  See the
       "PORTING from 1.X" section below for a list of known issues.

       This manpage documents the Apache2::Upload package.

       Apache2::Upload - Methods for dealing with file uploads.

       •   "$upload->next()"  is  no  longer  available;   please  use the "APR::Request::Param::Table" API when
           iterating over upload entries.

       •   info($header_name) is replaced by info($set).

       •   type() returns only the MIME-type portion of the Content-Type header.

       APR::Request::Param::Table, APR::Request::Error, Apache2::Request, APR::Table(3)

           use Apache2::Upload;

           $req = Apache2::Request->new($r);
           $upload = $req->upload("foo");
           $size = $upload->size;

           # three methods to get at the upload's contents ... slurp, fh, io

           $upload->slurp($slurp_data);

           read $upload->fh, $fh_data, $size;
           ok $slurp_data eq $fh_data;

           my $io = $upload->io;
           print while <$io>;
