How can I get a json out of a value_type?

[nmkoremblum]

Hi, I am trying to convert a value_type value to a json object to match the stringification of a value, I tried many ways, ideally, I would love the following code to work:

int intVal{123456};
nlohmann::json::value_type intValT{intVal};
nlohmann::json intJson {intValT};
ASSERT_STREQ(to_string(intVal).data(), intJson.dump().data());

But it does not, not even the following code:

int intVal{123456};
nlohmann::json::value_type intValT{intVal};
nlohmann::json intJson = nlohmann::json::parse(intValT.dump());
ASSERT_STREQ(to_string(intVal).data(), intJson.dump().data());

The first throw:

Expected equality of these values:
  to_string(intVal).data()
    Which is: "123456"
  intJson.dump().data()
    Which is: "[[123456]]"

And the second throw:

Expected equality of these values:
  to_string(intVal).data()
    Which is: "123456"
  intJson.dump().data()
    Which is: "[123456]"

How can I convert the raw value from value_type to json to match the assert? Ideally, without using dump(). Another limitation would be that I won't know the value type in advance.

I really appreciate any help you can provide

Ok, this can be solved by doing:

int intVal{123456};
nlohmann::json::value_type intValT = intVal;
nlohmann::json intJson = intValT;
ASSERT_STREQ(to_string(intVal).data(), intJson.dump().data());
