Previously `ForceSendFields` had no effect on query parameters (only JSON body fields were honored), so such a parameter was silently omitted; it is now serialized with its explicit value (for example `cascade=false`). Callers that unknowingly relied on the previous no-op behavior will now send the parameter. + ### New Features and Improvements ### Bug Fixes +* Honor `ForceSendFields` for query parameters, including fields nested inside request sub-structs. A zero-valued scalar field (for example a `false` bool such as `cascade` on the pipelines Delete request) listed in `ForceSendFields` is now sent on the wire instead of being dropped by the `url` tag's `omitempty`, matching the existing behavior for JSON request bodies. + ### Documentation ### Internal Changes diff --git a/httpclient/request.go b/httpclient/request.go index d25123f76..d47c8055e 100644 --- a/httpclient/request.go +++ b/httpclient/request.go @@ -137,6 +137,12 @@ func makeQueryString(data interface{}) (string, error) { if err != nil { return "", fmt.Errorf("cannot create query string: %w", err) } + // go-querystring honors the `url` tag's omitempty option but knows + // nothing about ForceSendFields, so a zero-valued field (e.g. a false + // bool) listed in ForceSendFields would be dropped.
