@class IO::URI
|
||
|
|
|
||
|
|
An URI object can split a Uniform Resource Identifier string into
|
||
|
|
its components or build a string from URI components. Please note
|
||
|
|
that the memory footprint of an URI object is always bigger then
|
||
|
|
a pure String object, so if memory usage is of concern, it is advised
|
||
|
|
to keep paths as String objects around, and only use URI objects
|
||
|
|
to encode and decode them.
|
||
|
|
|
||
|
|
An URI is made of the following components, where most of them
|
||
|
|
are optional:
|
||
|
|
|
||
|
|
Scheme://UserInfo@Host:Port/LocalPath#Fragment?Query
|
||
|
|
|
||
|
|
Example URIs:
|
||
|
|
|
||
|
|
http://user:password@www.myserver.com:8080/index.html#main
|
||
|
|
http://www.myserver.com/query?user=bla
|
||
|
|
ftp://ftp.myserver.com/pub/bla.zip
|
||
|
|
file:///c:/temp/bla.txt
|
||
|
|
file://SambaServer/temp/blub.txt
|
||
|
|
|
||
|
|
Note that assigns will be resolved before splitting a URI into its
|
||
|
|
components, for instance the assign "textures" could be defined
|
||
|
|
as:
|
||
|
|
|
||
|
|
Assign("textures", "http://www.dataserv.com/myapp/textures/");
|
||
|
|
|
||
|
|
So a path to a texture URI could be defined as:
|
||
|
|
|
||
|
|
URI("textures:mytex.dds")
|
||
|
|
|
||
|
|
Which would actually resolve into:
|
||
|
|
|
||
|
|
http://www.dataserv.com/myapp/textures/mytex.dds
|
||
|
|
|
||
|
|
Decoding into components happens in the init constructor or the
|
||
|
|
Set() method in the following steps:
|
||
|
|
|
||
|
|
- resolve any assigns in the original string
|
||
|
|
- split into Scheme, Host and Path blocks
|
||
|
|
- resolve Host and Path blocks further
|
||
|
|
|
||
|
|
Enconding from components into string happens in the AsString()
|
||
|
|
method in the following steps:
|
||
|
|
|
||
|
|
- concatenate URI string from components
|
||
|
|
- convert part of the string back into an existing assign
