RapidJSON does not provide a straightforward way of serializing JSON to cout
(= stdout), but you can use OStreamWrapper
to do that:
#include <rapidjson/writer.h> #include <rapidjson/ostreamwrapper.h> // ... OStreamWrapper out(cout); Writer<OStreamWrapper> writer(out); doc.Accept(writer);
Full example:
#include <iostream> #include <rapidjson/document.h> #include <rapidjson/writer.h> #include <rapidjson/ostreamwrapper.h> using namespace rapidjson; using namespace std; int main() { // Generate document: {"text": "Hello JSON!"} Document doc; doc.SetObject(); // Make doc an object ! doc.AddMember("text", "Hello JSON!", doc.GetAllocator()); // Write to stdout OStreamWrapper out(cout); Writer<OStreamWrapper> writer(out); doc.Accept(writer); }
