如何使用从 json 解码的 boos 属性映射将数组转换为 stl 的向量
hash = {'time_series':[1.0,1.0])
ptree pt2;
std::istringstream is (content); read_json (is, pt2);
std::vector<double> time_series = pt2.get("time_series");
../src/rtbTimeSeries.cpp:172:62: error: no matching function for call to ‘boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> >::get(const char [12])’
