Add a placeholder for get<string>() is value is nullptr

[alex-lt-kong]

Currently I am doing something like this

std::string myVal = myJson["myKey"] == nullptr ? "<empty>": myJson["myKey"].get<string>();

to make sure myVal is always a valid std::string. Wondering if it is possible to supply a placeholder in case of null of the JSON object, perhaps something like this:

std::string myVal = myJson["myKey"].get<string>(if_null="<empty>");

Yes

std::string myVal = myJson.value("myKey", "<empty>");

Just tried the method mentioned by @gregmarr . Works like a charm! In case anyone wonders, if we have a nested value, can achieve the same like below:

std::string myVal = myJson.value("/myKey/alsoMyKey/moreKey"_json_pointer, "<empty>");
