NAME

6       Catalyst::Request::Upload - handles file upload requests
7

SYNOPSIS

9           my $upload = $c->req->upload('field');
10
11           $upload->basename;
12           $upload->copy_to;
13           $upload->fh;
14           $upload->decoded_fh
15           $upload->filename;
16           $upload->headers;
17           $upload->link_to;
18           $upload->size;
19           $upload->slurp;
20           $upload->decoded_slurp;
21           $upload->tempname;
22           $upload->type;
23           $upload->charset;
24
25       To specify where Catalyst should put the temporary files, set the
26       'uploadtmp' option in the Catalyst config. If unset, Catalyst will use
27       the system temp dir.
28
29           __PACKAGE__->config( uploadtmp => '/path/to/tmpdir' );

DESCRIPTION

34       This class provides accessors and methods to handle client upload
35       requests.
36

METHODS

38   $upload->new
39       Simple constructor.
40
41   $upload->copy_to
42       Copies the temporary file using File::Copy. Returns true for success,
43       false for failure.
44
45            $upload->copy_to('/path/to/target');
46
47       Please note the filename used for the copy target is the 'tempname'
48       that is the actual filename on the filesystem, NOT the 'filename' that
49       was part of the upload headers.  This might seem counter intuitive but
50       at this point this behavior is so established that its not something we
51       can change.
52
53       You can always create your own copy routine that munges the target path
54       as you wish.
55
56   $upload->is_utf8_encoded
57       Returns true of the upload defines a character set at that value is
58       'UTF-8'.  This does not try to inspect your upload and make any guesses
59       if the Content Type charset is undefined.
60
61   $upload->fh
62       Opens a temporary file (see tempname below) and returns an IO::File
63       handle.
64
65       This is a filehandle that is opened with no additional IO Layers.
66
67   $upload->decoded_fh(?$encoding)
68       Returns a filehandle that has binmode set to UTF-8 if a UTF-8 character
69       set is found. This also accepts an override encoding value that you can
70       use to force a particular PerlIO layer.  If neither are found the
71       filehandle is set to :raw.
72
73       This is useful if you are pulling the file into code and inspecting
74       bits and maybe then sending those bits back as the response.  (Please
75       note this is not a suitable filehandle to set in the body; use "fh" if
76       you are doing that).
77
78       Please note that using this method sets the underlying filehandle IO
79       layer so once you use this method if you go back and use the "fh"
80       method you still get the IO layer applied.
81
82   $upload->filename
83       Returns the client-supplied filename.
84
85   $upload->headers
86       Returns an HTTP::Headers object for the request.
87
88   $upload->link_to
89       Creates a hard link to the temporary file. Returns true for success,
90       false for failure.
91
92           $upload->link_to('/path/to/target');
93
94   $upload->size
95       Returns the size of the uploaded file in bytes.
96
97   $upload->slurp(?$encoding)
98       Optionally accepts an argument to define an IO Layer (which is applied
99       to the filehandle via binmode; if no layer is defined the default is
100       set to ":raw".
101
102       Returns a scalar containing the contents of the temporary file.
103
104       Note that this will cause the filehandle pointed to by "$upload->fh" to
105       be reset to the start of the file using seek and the file handle to be
106       put into whatever encoding mode is applied.
107
108   $upload->decoded_slurp(?$encoding)
109       Works just like "slurp" except we use "decoded_fh" instead of "fh" to
110       open a filehandle to slurp.  This means if your upload charset is UTF8
111       we binmode the filehandle to that encoding.
112
113   $upload->basename
114       Returns basename for "filename".  This filters the name through a
115       regexp "basename =~ s|[^\w\.-]+|_|g" to make it safe for filesystems
116       that don't like advanced characters.  This will of course filter UTF8
117       characters.  If you need the exact basename unfiltered use
118       "raw_basename".
119
120   $upload->raw_basename
121       Just like "basename" but without filtering the filename for characters
122       that don't always write to a filesystem.
123
124   $upload->tempname
125       Returns the path to the temporary file.
126
127   $upload->type
128       Returns the client-supplied Content-Type.
129
130   $upload->charset
131       The character set information part of the content type, if any.  Useful
132       if you need to figure out any encodings on the file upload.
