Question

我的API将DSS服务作为后端，并具有用于GET，POST，PUT和DELETE操作的关联资源。但是，当我对服务发出DELETE操作时，即使在后端发生成功，APIM也会返回运行时错误：

curl -v -H "Authorization: Bearer 356bcb27f82c849e383d3765e0ccce" -X DELETE http://localhost:8280/fte/1.0/users/105/vacations/13

如何防止出现此类错误？我是否需要来自后端服务的输出消息，以便它不显示此运行时错误？

这是因为您的后端服务不响应邮件正文。而是仅发送HTTP状态代码。 APIManager尝试从该空载荷构建消息。为了防止你打开api配置（repository / deploymnet / server / synapse-config / default / api）对于DELETE操作，在发送到后端之前通过设置OUT_ONLY属性使其成为单向消息。

<property name="OUT_ONLY" value="true"/>

确保仅为DELETE操作设置该属性。如果其他操作返回任何响应主体，则此属性将影响它们。
