Question

在运行代码时获得以下异常：

     FhirContext ctx = FhirContext.forR4();

    // Create a FhirInstanceValidator and register it to a validator
    FhirValidator validator = ctx.newValidator();
    FhirInstanceValidator instanceValidator = new FhirInstanceValidator();
    validator.registerValidatorModule(instanceValidator);

    /*
     * If you want, you can configure settings on the validator to adjust
     * its behaviour during validation
     */
    instanceValidator.setAnyExtensionsAllowed(true);
    // input is Patient resource in String https://www.hl7.org/fhir/patient-example.json.html 
    ValidationResult result = validator.validateWithResult(input);

我正在使用Hapi库来验证资源（如果我没有记错的话，这是患者资源https://www.hl7.org/fhir/patient-example.json.html）。我已经将此患者Json存储在字符串中并尝试验证其：

1：结构->我认为使用Parse Validation可以实现，而且我做到了。 2：基数->我创建了两个“ active：true” Json键值对，认为它将引发基数错误，但SchemxxxValidator / ParseValidator / InstanceValidator都不起作用。 ...

如何根据此处https://www.hl7.org/fhir/validation.html（结构，基数，ValueDomains ...）列出的属性来验证资源，我是否必须使用所有三种方法那就是解析器，FhirInstanceValidator和SchemaBaseValidator / SchematronBaseValidator。

由于我是FHIR的新手，请为我的la脚问题提供帮助。

Answer 1

基数->我创建了两个“ active：true” Json键值对，以为它将引发基数错误，但SchemxxxValidator / ParseValidator / InstanceValidator都不起作用。 ...

这是HAPI中的问题-它会验证从JSON加载的对象，并且JSON解析器会静默删除重复的属性键。如果直接使用验证器，则不会发生。我相信这将在某个阶段得到解决

generateSnapshot失败

这是一个真实的问题-我不确定为什么未设置它，但是如果未生成快照，验证器将无法工作

使用HAPI库针对https://www.hl7.org/fhir/validation.html上列出的不同方面对FHIR资源进行验证
