No suitable method for adding c++ stl string to C++ rest sdk json object utility string_t

Question

I want to add a string into C++ rest sdk json object. I tried

json::value obj;
obj[L"Login"] = json::value::string();

But the problem is this adds only strings as U("str") and not const std::string. So I can add as

obj[L"Login"] = json::value::string(U("Login"));

but not do as follows:

json::value obj;
string Login= "login";
obj[L"Login"] = json::value::string(Login);

I am using C++ rest sdk 2.8.0.

Try the following type conversion:

json::value obj;
string Login= "login";
std::wstring_convert<std::codecvt_utf8<wchar_t> > converter;
std::wstring uLogin = converter.from_bytes(Login);
obj[L"Login"] = json::value::string(uLogin);
