PHP Build OAuth2.0

These days have been engaged in OAuth2.0 things, write SDK what, in order to more in-depth understanding of the service side of the OAuth authentication mechanism, I built a PHP under the OAuth environment, and transplanted it into their own relatively familiar TP framework.

Don't say much nonsense, start.

In fact, there are OAuth2.0 PHP version of the Internet.

You can find the source code in http://code.google.com/p/oauth2-php/, which implements the data pattern for PDO and MongoDB. Here I am also based on this code in the TP integration.

OK, here we can download the package to unzip, the Lib under the Oauth.inc renamed to OAuth2.class.php and placed in the directory under the TP core package:

/extend/library/org/oauth/oauth2.class.php

Next we will inherit this class;

Create a new ThinkOAuth2.class.php file in this directory:

VALUES ("${code}", "${client_id}", "${redirect_uri}", "${expires}", "${scope}") "; $result = db-A-$this, execute ($  SQL);   }/** * Overrides oauth2::checkusercredentials (). * @see oauth2::checkusercredentials () */protected function checkusercredentials ($client _id, $username, $password) {RE  Turn TRUE; }}

Here we need to create the database:

SQL code:

CREATE TABLE ' oauth_client ' (' ID ' bigint () not null auto_increment, ' client_id ' varchar (+) NOT NULL, ' Client_secret   ' varchar ' NOT NULL, ' Redirect_uri ' varchar ($) NOT null, ' create_time '  timestamp not null DEFAULT now (),  PRIMARY KEY (' id ')) engine=myisam auto_increment=3 DEFAULT Charset=utf8; CREATE TABLE ' Oauth_code ' (' ID ' bigint () not null auto_increment, ' client_id ' varchar (+) NOT null, ' user_id ' varcha  R (+) not NULL, ' code ' varchar (+) NOT null, ' Redirect_uri ' varchar ($) NOT NULL, ' expires ' int (one) not null, ' scope ' varchar (+) default NULL, PRIMARY KEY (' id ')) engine=myisam default Charset=utf8; CREATE TABLE ' Oauth_token ' (' ID ' bigint () not null auto_increment, ' client_id ' varchar (+) NOT null, ' user_id ' Varch   AR (+) not null, ' access_token ' varchar (+) NOT null, ' refresh_token ' varchar (+) NOT NULL, ' expires ' int (one) not NULL, ' Scope ' varchar ($) Default NULL, PRIMARY KEY (' id ')) engine=myisam auto_increment=2 default Charset=utF8; 

The database table name above can be arbitrarily fixed, but to configure the table name in config.php:

' oauth2_codes_table ' = ' oauth_code ', ' oauth2_clients_table ' = ' oauth_client ', ' oauth2_token_table ' and ' = ' Oauth_token ',

If the OAuth server is not the current server, then the DSN address must be defined:

' Oauth2_db_dsn ' = ' mysql://root:[email protected]:3306/database '

Okay, so that's the approximate core library code. The next step is to use it

We create an OAuth action that is responsible for some validation of OAuth2 (OauthAction.class.php)

Import ("ORG. Oauth.thinkoauth2 "), class Oauthaction extends Action {private $oauth = Null;function _initialize () {Header ("    Content-type:application/json "); <span style= "WHITE-SPACE:PRE;"    ></span>header ("Cache-control:no-store"), $this, OAuth = new ThinkOAuth2 (); }public function Index () {header ("Content-type:application/json;    Charset=utf-8 "), $this-Ajaxreturn (null, ' Oauth-server-start ', 1, ' json '); }public function Access_token () {$this, OAuth, Grantaccesstoken ();} Permission validation Public Function authorize () {if ($_post) {$this, OAuth, Finishclientauthorization ($_post["accept"] = = "Ye    P ", $_post); return;} form Preparation $auth_params = OAuth, $this, Getauthorizeparams (), $this, assign ("params", $auth _params); $this- >display ();} Public Function addclient () {if ($_post && isset ($_post["client_id"]) && isset ($_post["Client_secret"] ) && isset ($_post["Redirect_uri")) {$this, OAuth, Addclient ($_post["Client_id "], $_post[" Client_secret "], $_post[" Redirect_uri "]); return;} $this->display ();}}

Here we create a private OAuth object and go to init it at initialization time.

The above code is not validated in the password section, and the third pattern requires rewriting the Checkusercredentials method in the Thinkoauth class.

Go ahead, we write a restricted resource code. We are not using AOP to intercept, so I'm going to use a base class directly to simulate interception.

Import ("ORG. Oauth.thinkoauth2 "), class Baseaction extends Action {protected $oauth = Null;function _initialize () {$this, OAuth = NE W ThinkOAuth2 ();    }    Public Function Index () {        if (! $this, OAuth-Verifyaccesstoken ()) {        $this-ajaxreturn (null, ' No,no, No ', 0, ' json ');        Exit ();        } $this-Ajaxreturn (null, ' Oauth-server ', 1, ' json ');}    }

The next step is to use a useraction to inherit it for a limited purpose, as follows:

Class Useraction extends Baseaction {public    function index () {if (! $this, OAuth, Verifyaccesstoken ()) {        $this-Ajaxreturn (null, ' No,no,no ', 0, ' json ');        } $this-Ajaxreturn (null, ' Oauth-server ', 1, ' json ');}    }

Finally, why do you want to couple user_id into the OAuth table? Because we sometimes need to return from Access_token to check user_id, the above table can solve this problem, but in fact there is a way to automatically include user_id for Access_token generation, and then encrypt, when decoding from Access_ Tokens can be removed directly from the user_id. Here about user_id and password authentication are not implemented, you need to inherit the ThinkOAuth2 class later or modify the Checkusercredentials method to achieve. in addition this set of things used in rest mode I think better!
