# HTTP::Body(3pm)

HTTP Body Parser

## NAME

HTTP::Body - HTTP Body Parser

## SYNOPSIS

```
    use HTTP::Body;

    sub handler : method {
        my ( $class, $r ) = @_;
        my $content_type   = $r->headers_in->get('Content-Type');
        my $content_length = $r->headers_in->get('Content-Length');

        my $body   = HTTP::Body->new( $content_type, $content_length );
        my $length = $content_length;
        while ( $length ) {
            $r->read( my $buffer, ( $length < 8192 ) ? $length : 8192 );
            $length -= length($buffer);

            $body->add($buffer);
        }

        my $uploads     = $body->upload;     # hashref
        my $params      = $body->param;      # hashref
        my $param_order = $body->param_order # arrayref
        my $body        = $body->body;       # IO::Handle
    }
```

## DESCRIPTION

HTTP::Body parses chunks of HTTP POST data and supports application/octet-stream, application/json, application/x-www-form-urlencoded, and multipart/form-data.

Chunked bodies are supported by not passing a length value to **new()**.

It is currently used by Catalyst, Dancer, Maypole, Web::Simple and Jedi.

## NOTES

When parsing multipart bodies, temporary files are created to store any uploaded files.  You must delete these temporary files yourself after processing them, or set `$body`-\>**cleanup**(1) to automatically delete them at DESTROY-time.

With version 1.23, we have changed the basic behavior of how temporary files are prepared for uploads.  The extension of the file is no longer transferred to the temporary file, the extension will always be `".upload"`.  We have also introduced variables that make it possible to set the behavior as required.

- $HTTP::Body::MultiPart::file\_temp\_suffix

  This is the extension that is given to all multipart files. The default setting here is `".upload"`.  If you want the old behavior from before version 1.23, simply undefine the value here.

- $HTTP::Body::MultiPart::basename\_regexp

  This is the regexp used to determine out the file extension.  This is of course no longer necessary, unless you undefine `"HTTP::Body::MultiPart::file_temp_suffix"`.

- $HTTP::Body::MultiPart::file\_temp\_template

  This gets passed through to the File::Temp TEMPLATE parameter.  There is no special default in our module.

- %HTTP::Body::MultiPart::file\_temp\_parameters

  In this hash you can add up custom settings for the File::Temp invokation. Those override every other setting.

## METHODS

- new

  Constructor. Takes content type and content length as parameters, returns a HTTP::Body object.

- add

  Add string to internal buffer. Will call spin unless done. returns length before adding self.

- body

  accessor for the body.

- chunked

  Returns 1 if the request is chunked.

- cleanup

  Set to 1 to enable automatic deletion of temporary files at DESTROY-time.

- content\_length

  Returns the content-length for the body data if known. Returns -1 if the request is chunked.

- content\_type

  Returns the content-type of the body data.

- init

  return self.

- length

  Returns the total length of data we expect to read if known. In the case of a chunked request, returns the amount of data read so far.

- trailing\_headers

  If a chunked request body had trailing headers, trailing\_headers will return an HTTP::Headers object populated with those headers.

- spin

  Abstract method to spin the io handle.

- state

  Returns the current state of the parser.

- param

  Get/set body parameters.

- upload

  Get/set file uploads.

- part\_data

  Just like 'param' but gives you a hash of the full data associated with the part in a multipart type POST/PUT.  Example:

  ```
      {
        data => "test",
        done => 1,
        headers => {
          "Content-Disposition" => "form-data; name=\"arg2\"",
          "Content-Type" => "text/plain"
        },
        name => "arg2",
        size => 4
      }
  ```

- tmpdir

  Specify a different path for temporary files.  Defaults to the system temporary path.

- param\_order

  Returns the array ref of the param keys in the order how they appeared on the body
