我不熟悉 JSON 和 FHIR。 我向返回药物分配对象的 FHIR 服务器发出请求。这是包含在字符串中的请求结果

我需要将其“转换”为 HL7.FHIR.Model.MedicationDispense 类型的对象，但我找不到该怎么做。
有人可以帮我吗？ 感谢您的时间和帮助
我在这里写了一篇关于如何构建 util 方法以从 FHIR 包中提取数据的文章： https://toreaurstad.blogspot.com/2022/06/making-use-of-extension-methods-to.html
你说你使用HL7.Fhir，所以检查你是否有这些包（版本可能因你的需要而异）
<PackageReference Include="Hl7.Fhir.R4" Version="4.0.0" />
<PackageReference Include="Hl7.Fhir.Serialization" Version="4.0.0" />
<PackageReference Include="Hl7.Fhir.Support" Version="4.0.0" />
<PackageReference Include="Hl7.Fhir.Support.Poco" Version="4.0.0" />
要提取药物声明剂量，这是 FHIR 中的一个概念，您可以：
在将成为您的领域模型的类中创建一个具有逻辑的包装器属性。这只是一个包含您的数据的类，它将从 Json 包内的 datda 构建。
public int? Fentanyl
{
get
{
var dosageQuantity = _bundle.SearchMedicationStatements("http://someacme.no/fhir/MedicationStatement/")
?.GetMedicationDosageQuantity("Fentanyl", "ug");
//value is already a decimal? data type and must be parsed
if (int.TryParse(dosageQuantity?.Value?.ToString(), out var dosageQuantityParsed))
{
return dosageQuantityParsed;
}
return null;
}
}
public static List<MedicationStatement>? SearchMedicationStatements(this Bundle bundle, string resourcePath)
{
var medicationStatementsMatching = bundle?.Entry?.Where(e => e.FullUrl.StartsWith(resourcePath))?.Select(m => m.Resource)?.OfType<MedicationStatement>()?.ToList();
return medicationStatementsMatching;
}
public static Dosage? GetMedicationDosageDosage(this List<MedicationStatement> medicationStatements, string displayText)
{
//find dosage with given display text
foreach (var medicationStatement in medicationStatements)
{
var medicationStatementMedication = medicationStatement?.Medication as CodeableConcept;
if (medicationStatementMedication == null)
{
continue;
}
var medicationCoding = medicationStatementMedication?.Coding?.FirstOrDefault(med => med.Display?.Equals(displayText, StringComparison.InvariantCultureIgnoreCase) == true);
if (medicationCoding != null)
{
var quantity = medicationStatement?.Dosage?.FirstOrDefault();
return quantity;
}
}
return null;
}
当然，这不仅仅是您的领域模型。您必须将 Bundle 类型的包传递到此域模型中，例如通过域模型的构造函数。
像这样的东西：
var bundle = new FhirJsonParser().Parse(await result.Content.ReadAsStringAsync());
我建议您使用以下方法处理您的 FHIR 映射：
