红帽全球峰会244.4. 端点选项
端点 URI 中都可以提供任何端点选项，或者在消息标头中动态提供。消息标头名称必须是 CamelOlingo2.<option> 的格式。请注意， inBody 选项会覆盖消息标头，例如， Body=option 中的 endpoint 选项会覆盖 CamelOlingo2.option 标头。另外，也可以指定查询参数。
| 名称 | 类型 | 描述 |
|---|---|---|
| data | 对象 | 用于创建或修改 OData 资源的适当类型的数据 |
| keyPredicate | 字符串 | 创建参数化 OData 资源端点的关键 predicate。对于在标头中动态提供 key predicate 值的 create/update 操作 |
| queryParams | java.util.Map<String,String> | OData 系统选项和自定义查询选项。如需更多信息，请参阅 OData 2.0 URI Conventions |
| resourcePath | 字符串 | OData 资源路径，不可包含键 predicate |
| endpointHttpHeaders | java.util.Map<String, String> | 要发送到端点的动态 HTTP 标头 |
| responseHttpHeaders | java.util.Map<String, String> | 端点的动态 HTTP 响应标头 |
请注意，resourcePath 选项可以在 URI 路径中指定，作为端点选项 ?resourcePath=<resource-path> 或作为标头值 CamelOlingo2.resourcePath。OData 实体键 predicate 可以是资源路径的一部分，例如 Manufacturers ( '1' )，其中 '__1' 是键 predicate，或者与资源路径 Manufacturers 和 keyPredicate 选项 '1' 分开指定。
| 端点 | 选项 | HTTP 方法 | 结果 Body 类型 |
|---|---|---|---|
| batch | data, endpointHttpHeaders | 带有多部分/批批请求的 POST | java.util.List<org.apache.camel.component.olingo2.api.batch.Olingo2BatchResponse> |
| create | data, resourcePath, endpointHttpHeaders | POST | org.apache.olingo.odata2.api.ep.entry.ODataEntry 用于新条目 org.apache.olingo.odata2.api.commons.HttpStatusCodes for other OData 资源 |
| delete | resourcePath, endpointHttpHeaders | DELETE | org.apache.olingo.odata2.api.commons.HttpStatusCodes |
| merge | data, resourcePath, endpointHttpHeaders | MERGE | org.apache.olingo.odata2.api.commons.HttpStatusCodes |
| patch | data, resourcePath, endpointHttpHeaders | PATCH | org.apache.olingo.odata2.api.commons.HttpStatusCodes |
| 读取 | queryParams, resourcePath, endpointHttpHeaders | GET | 取决于接下来要查询的 OData 资源 |
| update | data, resourcePath, endpointHttpHeaders | PUT | org.apache.olingo.odata2.api.commons.HttpStatusCodes |
