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
}
当我发布此数据集时，api平台的响应是提供了无效的值（无效的IRI？）
这是堆栈跟踪

"@type": "hydra:Error",
"hydra:title": "An error occurred",
"hydra:description": "Invalid value provided (invalid IRI?).",

您可以看到，数组的每个对象中的请求中都存在IRI，但是api平台仍会引发错误的IRI错误。
使用级联持久选项配置实体
您对如何解决这种情况有任何建议吗？
预先感谢
答案 0 :(得分：0)
您是否能够找到这种行为的原因？我可能正面临着同样的问题。
$ 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，则可以轻松地使用IRI并创建Entity。如果patientDiseases是OneToMany（实际上它也是ManyToMany，但具有额外的属性），则在对象集合内部使用IRI返回上面的Exception。而且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，我只能找到一种解决方法。必须将在此处PatientDisease具有期望名称的实体定义为ApiResource，至少具有强制性的GET itemOperation（可以轻松地是一个虚拟控制器，始终返回“未找到”）。然后，ApiPlatform可能会更好地了解对象集合的格式，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。但我希望这对其他人也有帮助：-）
