使用axios在vuejs应用程序中工作我有一些数据结构如下：
{
...
surgeries: [],//array of object
patientDiseases: [
{
date: a javascrtipt date,
disease: /api/diseases/#id //This is a valid IRI provided by the api in a select
}
] //array of object
}
当我发布这个数据集时api-platform的响应是提供的无效值（无效的IRI？）
这是堆栈跟踪

"hydra:title": "An error occurred",

正如您所看到的，IRI存在于数组的每个对象的请求中，但是api-platform仍然引发了无效IRI的错误。
实体配置了级联持久选项
您对我如何解决这种情况有什么建议吗？
提前致谢
你能找到这种行为的原因吗？我只是面对同样的问题。
$ composer info
api-platform/core v2.3.5 Build a fully-featured hypermedia or GraphQL API in minutes
symfony/serializer v4.2.2 Symfony Serializer Component
如果（在您的示例中）surgeries是ManyToMany关系，您可以轻松使用IRI并创建实体。如果patientDiseases是OneToMany（事实上它也是ManyToMany，但有额外的属性），在对象集合中使用IRI会返回上面的Exception。对象规范化看起来很奇怪：
["object", "App\\Entity\\Disease"], -> $object
["integer", 0], -> $attribute, but here it uses key 0 from array/collection instead of 'disease'?!
["string", "\/api\/diseases\/4"], -> $value
经过多次尝试，我找到了一个解决方法。这里具有预期名称的实体PatientDisease必须被定义为ApiResource，至少具有强制性GET itemOperation（可以很容易地返回总是“未找到”的虚拟控制器）。然后ApiPlatform可能更好地理解对象集合的格式，并成功创建新的嵌入式实体。
我不知道这是预期的行为还是错误。但我希望这可能也有助于其他人:-)
