如何从 python 中的 fhirclient-4.0.0 prepare() 方法修复 'FHIRValidationError'？

Question

我正在使用 hapi R4 服务器测试 fhirclient 4.0.0 (Python 3.7)

settings = {
    'app_id': 'fhir',
#     'api_base': 'http://test.fhir.org/r4'
    'api_base': 'http://hapi.fhir.org/baseR4'
}
smart = client.FHIRClient(settings=settings)    

# capabilitystatement.CapabilityStatement.read_from('metadata', smart.server)
smart.prepare()

我收到此验证错误

FHIRValidationError: {root}:
  rest.0:
    resource.70:
      searchParam.14:
        'Non-optional property "type" on <models.capabilitystatement.CapabilityStatementRestResourceSearchParam object at 0x7fe54cef1668> is missing'

Link 到能力声明 http://hapi.fhir.org/baseR4/metadata

还有其他人面临这个问题吗？

Answer 1

HAPI 服务器 returns 一个无效的 CapabilityStatement 资源，其中尚未填写 Location 的 searchParam 'near' 类型 - 我对此进行了一些检查。所以错误不在您的客户端中；实际上，它通过告诉您跟踪末尾 "FHIRValidationError".

下面的错误来完美地工作

您最好的选择是联系 HAPI 服务器开发人员并要求他们更正他们的 CapabilityStatement。

Answer 2

您确定您正在使用 fhirclient 4.0.0 吗？虽然 4.0.0 已经推出一年多了 pip 仍然有版本 3.2.0. 这里有一个问题：https://github.com/smart-on-fhir/client-py/issues/70

对当前版本的 HAPI 使用 fhirclient 3.2.0 将导致类似的错误。您可以直接从他们的 github 克隆 fhirclient 或使用带有 DSTU3 的 HAPI 服务器。托管您自己的服务器时，您可以将配置 hapi.properties 更改为 fhir_version=DSTU3.
