            'password' => 'required',

  • After the download is completed, copy the src/zh-CN folder in the compressed package to the resources/lang folder in the project directory.
  • Modify the config->app.php file and modify the code as follows:

    'locale' => 'zh-CN',

• Since captcha does not have a Chinese explanation in the Chinese package, you need to manually add a Chinese explanation. The specific operations are as follows:
  • Open resources/zh-CN/validation.php, append the following key-value pairs to the total array:

    'captcha'                  => ':attribute 不正确。',

  • In attributes Append the following key-value pairs to the array:

    'captcha'               => '验证码',
