| extraParameters | 有关可传递的参数的完整列表，请参阅 ExtraParameters，可以是 NULL | map |
| iUrl | IIdType 通过绝对 url 引用资源 | IIdType |
| ifVersionMatches | 与服务器上最新版本匹配的版本 | 字符串 |
| resource | 要读取的资源（例如 Patient） | 类 |
| resourceClass | 要读取的资源（例如 Patient.class） | 字符串 |
| returnNull | 如果版本匹配，返回 null | 布尔值 |
| returnResource | 如果版本匹配，返回资源 | IBaseResource |
| throwError | 如果版本匹配 | 布尔值 |
| url | 通过绝对 url 引用资源 | 字符串 |
除了以上参数外，Fhir API 还可使用任何 Query 参数。
任何参数都可以在端点 URI 中提供，也可以在消息标头中动态提供。邮件标题名称必须为 CamelFhir.parameter.inBody 参数覆盖消息标头，例如，Body=myParameterNameHere 的 endpoint 参数会覆盖 CamelFhir.myParameterNameHere 标头。
