如何从 rapidjson::Document 获取中文的 wstring？

Question

我是一名学生，正在使用cpp 开发PC-Client。我不知道如何处理带有Unicode编码的rapidjson。我总是得到一个混乱的代码。我是cpp的jackeroo，我怎样才能得到正确的结果？非常感谢！

举个例子：

class Test {
    // I have got the string of json
    // eg: { "name" : "小明" }
    public : void test(const std::string& data) {
        rapidjson::Document json;
        json.Parse<0>(data.c_str());

        // there are a method GetString() , return a string
        // The name value are another Chinese characters(I guess which because of its encoding).
        // I want to get a wstring which value is "小明"(Not a messy code). How can i do ? 
        std::string name = json["name"].GetString();
    }
};


// I had used this method
// But still got a messy code
str::UnicodeToAnsi();

Answer 1

#include <codecvt>
#include <string>

// convert UTF-8 string to wstring
std::wstring utf8_to_wstring (const std::string& str)
{
    std::wstring_convert<std::codecvt_utf8<wchar_t>> myconv;
    return myconv.from_bytes(str);
}

// convert wstring to UTF-8 string
std::string wstring_to_utf8 (const std::wstring& str)
{
    std::wstring_convert<std::codecvt_utf8<wchar_t>> myconv;
    return myconv.to_bytes(str);
}

Convert wstring to string encoded in UTF-8谢谢！
