Boost PropertyTree: How to read json array into?
So having such json:
{
"config": {
"name": "myconfig",
"servecies": {
"module": [
"file",
"Admin",
"HR"
],
"notModule": "MyNotModule"
}
}
}
How to parse module array into multimap<string,string>? and is it possible to find out if module is an array and notModule is not?

-1: You asked this question yesterday, but you apparently didn't like the answer. Boost.PropertyTree is not a general JSON parser; you cannot load any JSON file and build a Boost.PropertyTree from it. If you need a JSON parser, I would suggest finding one.

Use a JSON parser. There isn't really anything in C++ that will do all the work for you, you must use an external parser (or roll out your own) and interpret the events as it steps through.
I have had a good experience with jsoncpp, and there are a few others listed on json.org under the C++ section.

boost::property_tree::json_parser::read_json("file.json", property_tree_root);
parses file.json and puts the root in property_tree_root.
The children in the property tree will have names, except those that are array elements.
