DeregisterTargets

POST

Unbind one or more real servers from a CLB listener or forwarding rule. For layer-4 listeners, only the listener ID needs to be specified. For layer-7 listeners, the forwarding rule also needs to be specified through LocationId or Domain+Url.

Wire call

Converge Cloud is RPC over HTTP. There is one path — / — and the action travels in the X-TC-Action header. The /clb/DeregisterTargets path used in the OpenAPI document is a documentation convenience so each action is addressable; it is not a route on the server.

Response

Fields are returned inside the Response envelope. Converge Cloud answers HTTP 200 for errors as well as successes, so read Response.Error rather than the status code — and test for the presence of that object, because Code is occasionally the empty string.

FieldTypeDescription
RequestIdstringThe unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem.
