Member Function Documentation

GetServerContext()

grpc::ServerContext & ugrpc::server::CallContext::GetServerContext

(

)

Returns

the ServerContext used for this RPC

GetStorageContext()

utils::AnyStorage< StorageContext > & ugrpc::server::CallContext::GetStorageContext

(

)

Returns call context for storing per-call custom data.

The context can be used to pass data from server middleware to client handler or from one middleware to another one.

Example usage:

In authentication middleware:

if (password_is_correct) {
  // Username is authenticated, set it in per-call storage context
  ctx.GetCall().GetStorageContext().Emplace(kAuthUsername, username);
}

In client handler:

const auto& username = context.GetStorageContext().Get(kAuthUsername);
auto msg = fmt::format("Hello, {}!", username);
