What is the best way to deal with json?

Question

PostgreSQL

"{\"tags_in\":[102],\"tags_out\":[98]}"
Such json can only be parsed like this:

(campaign.search #>> '{}')::json->'tags_in' AS tags_in

- Ugly, inconvenient

What to do, why the data is automatically screened?

* campaign.search::json->'tags_in' AS tags_in- much better
