NAME

       IO::All::LWP - IO::All interface to LWP

SYNOPSIS

           use IO::All;

           "hello world\n" > io('ftp://localhost/test/x');   # save to FTP
           $content < io('http://example.org');              # GET webpage

           io('http://example.org') > io('index.html');      # save webpage

DESCRIPTION

       This module acts as glue between IO::All and LWP, so that files can be read and written
       through the network using the convenient <IO:All> interface.  Note that this module is not
       "use"d directly: you just use IO::All, which knows when to autoload IO::All::HTTP,
       IO::All::HTTPS, IO::All::FTP, or IO::All::Gopher, which implement the specific protocols
       based on IO::All::LWP.

EXECUTION MODEL

       GET requests. When the IO::All object is opened, the URI is fetched and stored by the
       object in an internal file handle. It can then be accessed like any other file via the
       IO::All methods and operators, it can be tied, etc.

       PUT requests. When the IO::All object is opened, an internal file handle is created. It is
       possible to that file handle using the various IO::All methods and operators, it can be
       tied, etc. If $io->put is not called explicitly, when the IO::All object is closed, either
       explicitly via $io->close or automatically upon destruction, the actual PUT request is
       made.

       The bad news is that the whole file is stored in memory after getting it or before putting
       it. This may cause problems if you are dealing with multi-gigabyte files!

METHODS

       The simplest way of doing things is via the overloaded operators > and <, as shown in the
       SYNOPSIS. These take care of automatically opening and closing the files and connections
       as needed. However, various methods are available to provide a finer degree of control.

       This is a subclass of IO::All. In addition to the inherited methods, the following methods
       are available:

       •   ua

           Set or get the user agent object (LWP::UserAgent or a subclass). If called with a
           list, the list is passed to LWP::UserAgent->new. If called with an object, the object
           is used directly as the user agent. Note that there is a default user agent if no user
           agent is specified.

       •   uri

           Set or get the URI. It can take either a URI object or a string, and it returns an URI
           object. Note that calling this method overrides the user and password fields, because
           URIs can contain authentication information.

       •   user

           Set or get the user name for authentication. Note that the user name (and the
           password) can also be set as part of the URL, as in "http://me:secret@example.com/".

       •   password

           Set or get the password for authentication. Note that the password can also be set as
           part of the URL, as discussed above.

       •   get

           GET the current URI using LWP. Or, if called with an HTTP::Request object as a
           parameter, it does that request instead. It returns the HTTP::Response object.

       •   put

           PUT to the current URI using LWP. If called with an HTTP::Request object, it does that
           request instead. If called with a scalar, it PUTs that as the content to the current
           URI, instead of the current accumulated content.

       •   response

           Return the HTTP::Response object.

       •   request

           Does an LWP request. It requires an HTTP::Request object as a parameter.  Returns an
           HTTP::Response object.

       •   open

           Overrides the "open" method from IO::All. It takes care of GETting the content, or of
           setting up the internal buffer for PUTting. Just like the "open" method from IO::All,
           it can take a mode: '<' for GET and '>' for PUT.

       •   close

           Overrides the "close" method from IO::All. It takes care of PUTting the content.

DEPENDENCIES

       This module uses LWP for all the heavy lifting. It also requires perl-5.8.0 or a more
       recent version.
