在配置文件main.php中设置用户认证类，并注释掉cookies和session配置，因为Api客户端和WEB网站不同，通常不能使用cookies和session维持登录状态。
'user' => [
'identityClass' => 'common\models\User',
'enableAutoLogin' => true,
'enableSession' => false,
//'identityCookie' => ['name' => '_identity-backend', 'httpOnly' => true],
],
/*'session' => [
// this is the name of the session cookie used for login on the backend
'name' => 'advanced-backend',
],*/实现Api用户认证（登录功能）
复制一份common/models/UserLoginForm到common/models中并改名为ApiLoginForm，同时将remember me 和vitifyCode等相关功能取消，并重写login方法。代码如下：
'用户名',
'password' => '密码',
//'rememberMe' => '记住我',
//'vitifyCode' => '验证码',
];
}
/**
* {@inheritdoc}
*/
public function rules()
{
return [
// username and password are both required
[['username', 'password'], 'required'],
// rememberMe must be a boolean value
//['rememberMe', 'boolean'],
// password is validated by validatePassword()
['password', 'validatePassword'],
//['vitifyCode', 'captcha'], //验证码验证
];
}
/**
* Validates the password.
* This method serves as the inline validation for password.
*
* @param string $attribute the attribute currently being validated
* @param array $params the additional name-value pairs given in the rule
*/
public function validatePassword($attribute, $params)
{
if (!$this->hasErrors()) {
$user = $this->getUser();
if (!$user || !$user->validatePassword($this->password)) {
$this->addError($attribute, 'Incorrect username or password.');
}
}
}
/**
* Logs in a user using the provided username and password.
*
* @return bool whether the user is logged in successfully
*/
public function login()
{
if ($this->validate()) {
// return Yii::$app->user->login($this->getUser(), $this->rememberMe ? 3600 * 24 * 30 : 0);
$access_token = $this->_user->generateAccessToken();
$this->_user->expire_at=time()+3600*7*24;//设定access_token过期时间
$this->_user->save();
Yii::$app->user->login($this->_user,3600*7*24);
return $access_token;
} else {
return false;
}
}
/**
* Finds user by [[username]]
*
* @return User|null
*/
protected function getUser()
{
if ($this->_user === null) {
$this->_user = User::findByUsername($this->username);
}
return $this->_user;
}
}
在common/models User中实现generateAccessToken，代码如下：
/**
* 生成access_token
* @return string
* @throws \yii\base\Exception
*/
public function generateAccessToken()
{
$this->access_token = Yii::$app->security->generateRandomString();
return $this->access_token;
}实现UserController控制器，实现login方法：
username = $_POST['username'];
$model->password = $_POST['password'];*/
//使用getBodyParams处理POST请求
$model->load(\Yii::$app->getRequest()->getBodyParams(),'');
if ($model->login()) {
return ['access_token' => $model->login()];
} else {
$model->validate();
return $model;
}
}
}
配置好url美化：
[
'class' => 'yii\rest\UrlRule',
'controller' => 'user',
'pluralize' => false,//访问资源不需要加s
'extraPatterns' => [
'POST login' => 'login',
'POST signup' => 'signup',
],
]测试登录api顺利获得accessToken:
认证状态的维持
：
维持认证状态，就是客户端如何⽤accesstoken这个令
牌，去访问服务端所提供的服务。
1，添加QueryParamAuth过滤器，在VideoDetailController：
public function behaviors()
{
return ArrayHelper::merge(parent::behaviors(), [
'authenticatior' => [
'class' => QueryParamAuth::className()
]
]);
}
可以看出认证已经生效。
我们带上有效的access-token去测试：
提示我们，要想顺利通过验证必须在common\models\User.php 实现个findIdentityByAccessToken方法。实现该方法：
public static function findIdentityByAccessToken($token, $type = null)
{
return static::find()
->where(['access_token'=>$token,'status'=>self::STATUS_ACTIVE])
->andWhere(['>','expire_at',time()])
->one();
}再次带上access-token去测试，可以看出顺利得到想要的数据了：
我们还可以指定需要认证才能访问的动作。比如列表页不需要认证，详情需要：
public function behaviors()
{
return ArrayHelper::merge(parent::behaviors(), [
'authenticatior' => [
'class' => QueryParamAuth::className(),
'only' => ['view'],
],
]);
}Yii RestfulApi认证可以参考：Yii RestfulApi认证
过滤器可以参考：过滤器
用户注册实现
复制一份frontend/models/SignupForm到common/models中并改名为ApiSignupForm,并修改 代码如下：
'\common\models\User', 'message' => '用户名已被占用.'],
['username', 'string', 'min' => 2, 'max' => 255],
['email', 'trim'],
['email', 'required'],
['email', 'email'],
['email', 'string', 'max' => 255],
['email', 'unique', 'targetClass' => '\common\models\User', 'message' => 'Email已被占用.'],
['password', 'required'],
['password_repeat', 'required'],
['password', 'string', 'min' => 6],
['password_repeat','compare','compareAttribute'=>'password','message'=>'两次输入的密码不一致！'],
/*['realname','required'],
['realname','string','max'=>128],*/
];
}
public function attributeLabels()
{
return [
'username' => '用户名',
//'realname' => '姓名',
'password' => '密码',
'password_repeat'=>'重复密码',
'email' => '电子邮箱',
];
}
/**
* Signs user up.
*
* @return User|null the saved model or null if saving fails
* @throws \yii\base\Exception
*/
public function signup()
{
if (!$this->validate()) {
return null;
}
$user = new User();
$user->username = $this->username;
$user->email = $this->email;
//$user->realname=$this->realname;
$user->setPassword($this->password);
$user->generateAuthKey();
return $user->save() ? $user : null;
}
}
在UserController中实现 signup方法：
public function actionSignup()
{
$model = new ApiSignupForm();
$model->load(\Yii::$app->getRequest()->getBodyParams(),'');
if ($model->signup()) {
return ['result' =>'注册成功'];
} else {
$model->validate();
return $model;
}
}配置Url美化：
[
'class' => 'yii\rest\UrlRule',
'controller' => 'user',
'pluralize' => false,//访问资源不需要加s
'extraPatterns' => [
'POST login' => 'login',
'POST signup' => 'signup',
],
]测试：
