If not direct support we should have clear documentation on how to pass traces across http<>grpc boundaries.

研究方向
Review the 10 comments on the issue for suggested approaches or workarounds. The grpc gateway project generates gRPC to JSON proxies; to support OpenCensus trace propagation across HTTP/gRPC boundaries, you would likely need to add middleware or interceptors that extract/inject trace context. Check if there are existing tracing integrations in the codebase, e.g., in the 'runtime' package. Also, consider that the repository now may prefer OpenTelemetry over OpenCensus. If implementing, follow the OpenCensus Go propagation format. Alternatively, if the community decided on a documentation only fix, write clear instructions with code examples on how to manually propagate traces.
