laravel Auth验证的attempt如何使用账号或手机号

给你优化一下

$username = $request->username;

preg_match("/^((13[0-9])|(14[5,7])|(15[0-3,5-9])|(17[0,3,5-8])|(18[0-9])|166|198|199)\d{8}$/", $username) ?
    $credentials['phone'] = $username :
    $credentials['username'] = $username;

$credentials['password'] = $request->password;

if (!\Auth::guard('web')->attempt($credentials)) {
    return SysTools::response(CodeTool::code_error, CodeTool::code_error_login);
}
