Insert JSON into Mongocxx
bson, c++, json, mongo-cxx-driver, mongodb
Solution
A `bsoncxx::stdx::string_view` can be constructed from a `std::string`. Simply load your file contents (assuming it contains a single JSON object) into a `std::string` (perhaps via `std::ifstream`), and pass that `std::string` to `bsoncxx::from_json`. The object returned from `bsoncxx::from_json` is a `bsoncxx::document::value`, which is a resource-owning type that contains a BSON document.
Problem
I'm currently trying to insert a JSON file into my mongoDB. I've already seen that this was solved by making use of the mongo::BSONObj in the past... But this doesnt seem to be an option since they released the new mongocxx driver for c++11. This is what I found in the bsoncxx src files: ``` BSONCXX_API document::value BSONCXX_CALL from_json(stdx::string_view json); /// Constructs a new document::value from the provided JSON text /// /// @param 'json' /// A string_view into a JSON document /// /// @returns A document::value if conversion worked. /// /// @throws bsoncxx::exception with error details if the conversion failed. /// ``` How do I get my JSON file into a `stdx::string_view`? Thanks!
