Hi,
Are there any samples of using boost.json to deserialize boost.beast responses?
Not in the documentation of the two libraries as they are treated as separate self-contained concerns.
However it’s quite trivial.
Here's a simple example:
extern void use_json(boost::json::value const& jv);
void handle_read_text(boost::beast::flat_buffer& buf)
{
auto range = buf.data();
auto chars = boost::json::string_view(
reinterpret_cast<const char*>(range.data()),
range.size());
auto dom = boost::json::parse(chars);
use_json(dom);
}
The maintainers of beast and json are always available on the cpplang slack, in channel #beast.
The data() member of a flat_buffer contains a pointer and a size. Cast the pointer to const char * and use it and the size to construct a json::string_view.
From there you can call json::parse to get your json::value.
