python之JWT 如何与 django-phonenumber-field 一起工作

我用过django-phonenumber-field作为我的电话号码模型字段和序列化程序。它起作用了，一切都很好。现在，我正在尝试在这两个包的 Django Rest Framework 中实现 Json Web Token，djsoer 和 djangorestframework-jwt。我正在管理一个旧的 (django 1.11) 代码库并将其迁移到 Django2。现在，每当我尝试创建新的身份验证 token 时，都会收到内部服务器错误。 错误信息:

TypeError: Object of type 'PhoneNumber' is not JSON serializable 

我知道 Django-phonenumber-field 包中的 PhoneNumber 对象对此负责。但是，错误堆栈在 djangorestframework-jwt 中。如何在 JWT 上添加/传递 PhoneNumber 序列化程序？

[ 我不知道哪个代码库是必需的，所以我没有添加任何代码库。问我，我稍后描述/补充。]

TIA。

请您参考如下方法:

这与 JWT 无关。 Rest Framework 正在尝试将 Phonenumber 字段序列化为 json，但它不知道该怎么做。查看 DRF 文档以了解如何实现 a custom field -- 该字段负责了解如何在初始数据类型和序列化表示之间进行转换，反之亦然。
