How To Combine Two Json Values - json

Question

I have a text file with several hundred json entries.The first two entries look like this
{
"ip": "127.0.0.1",
"timestamp": "1565343832",
"ports": [{
"port": 80,
"proto": "tcp",
"status": "open",
"reason": "syn-ack",
"ttl": 245
}]
}
{
"ip": "127.0.0.2",
"timestamp": "1565343837",
"ports": [{
"port": 81,
"proto": "tcp",
"status": "open",
"reason": "syn-ack",
"ttl": 43
}]
}
I would like to parse this json file and combine the values for ip and port and put them in a text file.So the text file will have entries like this
127.0.0.1:80
127.0.0.2:81
How can this be done

Answer 1

Here is a C++ code example, use of boost::property_tree we can read json data and parse
ofstream outfile;
outfile.open ("entries.txt");
for (/*for loop for each entry*/) {
std::stringstream ss;
//assign input values to ss per entry
boost::property_tree::ptree pt;
boost::property_tree::read_json(ss, pt);
std::string IP = pt.get<std::string>("ip");
std::string PORT = pt.get<std::string>("ports.port");
outfile << IP << ":" <<PORT;
}
