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;

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.
