Hi, all!
It's possible to get following output from boost::property_tree::json_parser::write_json ?
{ "id": "id", "method": "test_method", "params": [] }
I know how to create array with some items, but when I try to create empty array, I've get "params": ""
Sorry, that's not possible. The fundamental problem is that PTree is only a rough match to JSON. PTree can have more complicated nodes, but JSON is typed. So when serializing a PTree as JSON, the serializer is guessing at the correct serialization form for each node: nodes with only named children become objects, those with only unnamed children become arrays, all others become strings. A PTree with a different data type than string could be a better match, but the current JSON functionality is not usable with such a tree. Sebastian
