Hi tmengCW
Yes most of the APIs in the C++ Rest SDK operate on the type utility::string_t. This is a platform dependent string type. It is a typedef to a std::wstring containing UTF-16 on Windows and a std::string containing UTF-8 on other platforms. We have an easy to use set of string conversion functions under the utility::conversions namespace that you should take a look at.
If you have a json::value that you know is a string value type then you could retrieve it and convert it to a std::string with something like the following:
