如何使用 Symfony 序列化器将字符串转换为 int

Question

我正在尝试将数组非规范化为一个对象，但是当非规范化方法遇到一个数字的代码字段时，它会出错，因为它是数组中的一个字符串，也许修复它很时髦

{
  "name": "Exception",
  "message": "The type of the \"code\" attribute for class \"App\\Http\\Response\\Flight\\DriverResponse\" must be one of \"int\" (\"string\" given).",
  "code": 0,
  "type": "Symfony\\Component\\Serializer\\Exception\\NotNormalizableValueException",
  "file": "/app/vendor/symfony/serializer/Normalizer/AbstractObjectNormalizer.php",
  "line": 445,
  "stack-trace": [
    "#0 /app/vendor/symfony/serializer/Normalizer/AbstractObjectNormalizer.php(331): Symfony\\Component\\Serializer\\Normalizer\\AbstractObjectNormalizer->validateAndDenormalize('App\\\\Http\\\\Respon...', 'code', '1', 'array', Array)",

    "#12 /app/web/index.php(14): yii\\base\\Application->run()",
    "#13 {main}"
  ]
}

我修好了，只需要通过这个设置[AbstractObjectNormalizer::DISABLE_TYPE_ENFORCEMENT => true]

$this->serializer->denormalize(
    $array,
    $class,
   'array',
   [AbstractObjectNormalizer::DISABLE_TYPE_ENFORCEMENT => true]
);
