Keys of JSON objects must be strings: The library does not convert the keys of the for (auto it = mymap.begin(); it != mymap.end(); ++it)
{
db[std::to_string(it->first)] = it->second;

Thanks, |
I'm actually ok with |
Nothing broken here: std::map<int, std::string> m;
m[1] = "one";
m[2] = "two";
std::cout << json(m) << std::endl; Output: [[1,"one"],[2,"two"]] |

Hi,
I'm trying to save a std::map<int, std::string> into a json, and then the json is saved in a file.
The problem is the result of the json:
I'm expecting this kind of output:
{ 1 : "one", 2 : "two"}
However, the result is:
[ [1, "one"], [2, "two"]]
So, when in other program I'm trying to read that file and try to save it in a json for doing the conversion to std::map again, I'm having the next error:
I've been looking in similar errors like #607, but I don't find a solution.
I've tried to build the map manually but the output is the same. Maybe I'm missing something.
Thanks in advance
