Minimal client usage after generating stubs with protoc-gen-connect-python.

import os from connectrpc.conformance import ConformanceServiceClient from connectrpc.conformance.v1 import conformance_pb2 client = ConformanceServiceClient( base_url=os.environ.get('CONFORMANCE_URL', 'http://localhost:8080'), ) req = conformance_pb2.UnaryRequest(name='hello') resp = client.unary(req) print(resp.message)

Debug

Known issues

breakingGenerated imports changed from connectrpc.conformance.v1.conformance_connect to connectrpc.conformance.v1.conformance_pb2_connect in v0.9.0.

fix

Update import statements to use the new module structure.

affects: >=0.9.0

gotchaprotoc-gen-connect-python generates files into the same output directory as protobuf stubs; must use --connect-python_out in protoc invocation.

fix

Ensure protoc command includes --connect-python_out=. in addition to --python_out and --grpc_python_out.

affects: all

deprecatedThe old connectrpc.conformance.v1.conformance_connect module is deprecated in favor of the _pb2_connect suffix.

fix

Regenerate stubs and update imports to use the new _pb2_connect modules.

affects: >=0.9.0
