ValidatePassword（）中的Yii2异常

Question

I use yii2 for developing web site.
Before save user to db, I encripted password like this:

$this->password = Yii::$app->security->generatePasswordHash($this->password);

And when I use this code:

Yii::$app->security->validatePassword("some string", $this->password);

I have error:

Invalid Parameter – yii\\base\\InvalidParamException Hash is invalid.

What is wrong?

Answer 1

I ran into the same issue. I realized that my password field's character capacity was too short for the hash, so I bumped it up from varchar(25) to varchar(255).

Answer 2

make sureyou have a column name exactly as password_hash in the user table and change your code from

Yii::$app->security->validatePassword("some string", $this->password);

to:

Yii::$app->security->validatePassword("some string", $this->password_hash);
