Apollo-link: Can I access cache in the link chain?

[goldenbearkin]

As subject, below snippet explains my intention.

new ApolloLink((operation, forward) => {
    const me = client.readQuery({
      query: gql`
          query meQuery {
            Me @client {
              name
              age
            }
          }
        `
    });
    console.log(me);
    return forward!(operation);
  }),

RM: I just make up the client object follow the Direct Cache Access section of the Apollo client's doc.

Why do I want to access the cache in the link chain?
Let say I need to refresh the idToken if it's expired, the refresh token logic should be done before the httpLink so that I can attach an non-expired token in the header. Also, if the refresh token process failed, I need to change the local state (apollo-link-state) sequentially and those components who is watching the local state can react upon the change.

@goldenbearkin you bet! You can do const { cache } = operation.getContext() to get access to the cache when using Apollo Client
