What's New in PHP OpenID 2.0
============================
This library implements both the OpenID 1 and OpenID 2 protocols. The
API changes in this version of the library are minimal and mostly
backwards-compatible with current RP and Server implementations. If
you're already using this library for OpenID 1, only a few small
changes (see Summary below) will be needed once you upgrade.
The big news here is compatibility with version 2.0 of the OpenID
protocol. Highlights include:
* Simple Registration support in a new module Auth/OpenID/SReg.php.
(Those previously using
Auth_OpenID_SuccessResponse::extensionResponse() are advised to
look here and at the example consumer and server for detailed usage
information.)
* OpenID provider-driven identifier selection.
* "Negotiators" allow you to define which association types to use.
* Improved examples/detect.php script (bugs fixed)
* Improved layout of example consumer (see examples/consumer)
* An improved HTML parser implementation
* Library is now immune to being included inside functions and
methods
* Fixes to avoid multibyte overloading problems
If you've written your own custom store or code that interacts
directly with it, you'll need to review the change notes for
Auth_OpenID_Interface in Auth/OpenID/Interface.php.
Upgrading from earlier versions of this library
-----------------------------------------------
One of the additions to the OpenID protocol was a specified nonce
format for one-way nonces. As a result, the nonce table in the
SQL-driven stores has changed. You'll need to run the Python script
contrib/upgrade-store-1.1-to-2.0 to upgrade your store, or you'll
encounter errors about the wrong number of columns in the oid_nonces
table. To run the script, you'll need a python module supporting your
database type: pysqlite2, psycopg, or MySQLdb.
If you cannot run the Python script, you can re-create your store by
dropping the tables in the store and calling createTables() on the
store object.
Consumers should now pass the consumer return_to URL to
Auth_OpenID_Consumer::complete() to defend against return_to URL
tampering. This has REPLACED the old parameter, $query. $query is
now a second optional parameter. It is STRONGLY RECOMMENDED that you
never override $query, since the OpenID library uses its own logic to
sidestep PHP's broken request-processing code.
Summary of API Changes
----------------------
- Auth_OpenID::fixArgs is now no longer necessary, and
Auth_OpenID_Consumer::complete and Auth_OpenID_Server::decodeRequest
no longer take query argument arrays. *You should no longer pass any
parameters to these methods.*
- Auth_OpenID_SuccessResponse::extensionResponse() is no longer the
preferred way to extract extension response parameters from the OpenID
response. Instead, see the Auth/OpenID/SReg.php module and the
example consumer and server for detailed usage information on
constructing Simple Registration requests and inspecting responses.
extensionResponse() is still valid, but now takes a second parameter
(bool) indicating whether extension args should be signed.
- The Auth_OpenID_Server's response answer() method now takes
additional parameters to support provider-driven identifier selection.
See the example server and the documentation for
Auth_OpenID_CheckIDRequest::answer.
- Auth_OpenID_Consumer::complete() now takes two args:
- $return_to, a required string that is the return URL passed to
Auth_OpenID_AuthRequest::redirectURL()
- $query, an optional array (or null if absent) denoting the query
parameters of the OpenID response. If null, the response data
will be extracted from the PHP request environment. Library
users SHOULD NOT ever pass anything for $query unless they're
testing the library.
