代码是用 Symfony 5 和 php 7.2.5 编写的。这是一个 API 代码，返回的数据应该是 JSON 格式。这是一个独特的错误，我找不到足够的信息来解决它。

我也有同样的问题。它来自二进制类型。以下是Doctrine 文档对这种类型的说明：

映射和转换具有最大长度的二进制字符串数据。如果您知道要存储的数据总是适合指定的长度，您应该考虑使用这种类型。从数据库中检索的值始终转换为 PHP 的资源类型，如果不存在数据，则为 null。

就我而言，我将 type="binary" 更改为 type="boolean" 并且它起作用了。

对于您的情况，您可能会考虑使用GUID 数据类型或像这样在您的 getter 中进行转换：

public function getUid()
{
    return (string) $this->uid;
}

吸气剂需要更新：

public function getUid(): ?string
{
    return is_resource($this->uid) ? stream_get_contents($this->uid) : $this->uid;
}

除此之外，您可能需要在代码中添加一些技巧，例如：

$device->setUid($device->getUid());

从设备表中读取该行后，您最终可能会拥有一个实体，其中 uid 属性的类型为“stream_resource”。使用 getter 的返回值调用 setter 将使其成为字符串。
