HTTP::DAV::Resource - Represents and interfaces with WebDAV Resources
SYNOPSIS
Sample
DESCRIPTION
Description here
CONSTRUCTORS
new Returns a new resource represented by the URI.
$r = HTTP::DAV::Resource->new(
-uri => $uri,
-LockedResourceList => $locks,
-Comms => $comms
-Client => $dav_client
);
On creation a Resource object needs 2 other objects passed in:
1. a "ResourceList" Object. This list will be added to if you lock this Resource.
2. a "Comms" Object. This object will be used for HTTP communication.
2. a "HTTP::DAV" Object. This object is where all locks are stored
METHODS
get/GET
Performs an HTTP GET and returns a DAV::Response object.
$response = $resource->get;
print $resource->get_content if ($response->is_success);
put/PUT
Performs an HTTP PUT and returns a DAV::Response object.
$response = $resource->put( $string );
$string is be passed as the body.
e.g.
$response = $resource->put($string);
print $resource->get_content if ($response->is_success);
Will use a Lock header if this resource was previously locked.
copy
Not implemented
move
Not implemented
delete
Performs an HTTP DELETE and returns a DAV::Response object.
$response = $resource->delete;
print "Delete successful" if ($response->is_success);
Will use a Lock header if this resource was previously locked.
options
Performs an HTTP OPTIONS and returns a DAV::Response object.
$response = $resource->options;
print "Yay for PUT!" if $resource->is_option("PUT");
mkcol
Performs a WebDAV MKCOL request and returns a DAV::Response object.
$response = $resource->mkcol;
print "MKCOL successful" if ($response->is_success);
Will use a Lock header if this resource was previously locked.
proppatch
xxx
propfind
Performs a WebDAV PROPFIND request and returns a DAV::Response object.
$response = $resource->propfind;
if ($response->is_success) {
print "PROPFIND successful\n";
print $resource->get_property("displayname") . "\n";
}
A successful PROPFIND fills the object with much data about the Resource. Including:
displayname
...
TODO
lock
Performs a WebDAV LOCK request and returns a DAV::Response object.
$resource->lock(
-owner => "Patrick Collins",
-depth => "infinity"
-scope => "exclusive",
-type => "write"
-timeout => TIMEOUT',
)
lock takes the following arguments.
owner - Indicates who locked this resource
The default value is:
DAV.pm/v$DAV::VERSION ($$)
e.g. DAV.pm/v0.1 (123)
If you use a URL as the owner, the module will automatically indicate to the server
that is is a URL (<D:href>http://...</D:href>)
depth - Indicates the depth of the lock.
Legal values are 0 or infinity. (1 is not allowed).
The default value is infinity.
A lock value of 0 on a collection will lock just the collection but not it's members,
whereas a lock value of infinity will lock the collection and all of it's members.
scope - Indicates the scope of the lock.
Legal DAV values are "exclusive" or "shared".
The default value is exclusive.
See section 6.1 of RFC2518 for a description of shared vs. exclusive locks.
type - Indicates the type of lock (read, write, etc)
The only legal DAV value currently is "write".
The default value is write.
timeout - Indicates when the lock will timeout
The timeout value may be one of, an Absolute Date, a Time Offset from now, or the word
"infinity".
The default value is "infinity".
The following are all valid timeout values:
Time Offset:
30s 30 seconds from now
10m ten minutes from now
1h one hour from now
1d tomorrow
3M in three months
10y in ten years time
Absolute Date:
timeout at the indicated time & date (UTC/GMT)
2000-02-31 00:40:33
timeout at the indicated date (UTC/GMT)
2000-02-31
You can use any of the Absolute Date formats specified in HTTP::Date (see perldoc
HTTP::Date)
Note: the DAV server may choose to ignore your specified timeout.
unlock
Performs a WebDAV UNLOCK request and returns a DAV::Response object.
$response = $resource->unlock()
$response = $resource->unlock( -force => 1 )
$response = $resource->unlock(
-token => "opaquelocktoken:1342-21423-2323" )
This method will automatically use the correct locktoken If: header if this resource
was previously locked.
force - Synonymous to calling $resource->forcefully_unlock_all.
forcefully_unlock_all
Remove all locks from a resource and return the last DAV::Response object. This method
take no arguments.
$response = $resource->forcefully_unlock_all;
This method will perform a lockdiscovery against the resource to determine all of the
current locks. Then it will UNLOCK them one by one. unlock( -token => locktoken ).
This unlock process is achievable because DAV does not enforce any security over
locks.
Note: this method returns the LAST unlock response (this is sufficient to indicate the
success of the sequence of unlocks). If an unlock fails, it will bail and return that
response. For instance, In the event that there are 3 shared locks and the second
unlock method fails, then you will get returned the unsuccessful second response. The
3rd unlock will not be attempted.
Don't run with this knife, you could hurt someone (or yourself).
steal_lock
Removes all locks from a resource, relocks it in your name and returns the
DAV::Response object for the lock command. This method takes no arguments.
$response = $resource->steal_lock;
Synonymous to forcefully_unlock_all() and then lock().
lockdiscovery
Discover the locks held against this resource and return a DAV::Response object. This
method take no arguments.
$response = $resource->lockdiscovery;
@locks = $resource->get_locks if $response->is_success;
This method is in fact a simplified version of propfind().
as_string
Returns a string representation of the object. Mainly useful for debugging purposes.
It takes no arguments.
print $resource->as_string
ACCESSOR METHODS (get, set and is)
is_option
Returns a boolean indicating whether this resource supports the option passed in as a
string. The option match is case insensitive so, PUT and Put are should both work.
if ($resource->is_option( "PUT" ) ) {
$resource->put( ... )
}
Note: this routine automatically calls the options() routine which makes the request
to the server. Subsequent calls to is_option will use the cached option list. To force
a rerequest to the server call options()
is_locked
Returns a boolean indicating whether this resource is locked.
@lock = $resource->is_locked( -owned=>[1|0] );
owned - this parameter is used to ask, is this resource locked by me?
Note: You must have already called propfind() or lockdiscovery()
e.g. Is the resource locked at all?
print "yes" if $resource->is_locked();
Is the resource locked by me?
print "yes" if $resource->is_locked( -owned=>1 );
Is the resource locked by someone other than me?
print "yes" if $resource->is_locked( -owned=>0 );
is_collection
Returns a boolean indicating whether this resource is a collection.
print "Directory" if ( $resource->is_collection );
You must first have performed a propfind.
get_uri
Returns the URI object for this resource.
print "URL is: " . $resource->get_uri()->as_string . "\n";
See the URI manpage from the LWP libraries (perldoc URI)
get_property
Returns a property value. Takes a string as an argument.
print $resource->get_property( "displayname" );
You must first have performed a propfind.
get_options
Returns an array of options allowed on this resource. Note: If $resource->options has
not been called then it will return an empty array.
@options = $resource->get_options
get_content
Returns the resource's content/body as a string. The content is typically the result
of a GET.
$content = $resource->get_content
get_content_ref
Returns the resource's content/body as a reference to a string. This is useful and
more efficient if the content is large.
${$resource->get_content_ref} =~ s/\bfoo\b/bar/g;
Note: You must have already called get()
get_lock
Returns the DAV::Lock object if it exists. Requires opaquelocktoken passed as a
parameter.
$lock = $resource->get_lock( "opaquelocktoken:234214--342-3444" );
get_locks
Returns a list of any DAV::Lock objects held against the resource.
@lock = $resource->get_locks( -owned=>[1|0] );
owned - this parameter indicates which locks you want.
- '1', requests any of my locks. (Locked by this DAV instance).
- '0' ,requests any locks not owned by us.
- any other value or no value, requests ALL locks.
Note: You must have already called propfind() or lockdiscovery()
e.g.
Give me my locks
@lock = $resource->get_locks( -owned=>1 );
Give me all locks
@lock = $resource->get_locks();
get_lockedresourcelist
get_parentresourcelist
get_comms
set_parent_resourcelist
$resource->set_parent_resourcelist( $resourcelist )
Sets the parent resource list (ask the question, which collection am I a member of?).
See HTTP::DAV::ResourceList.
