std::string 到 rapidJson 对象转换

Question

我试图将一个 std::string 转换为以下格式的rapidJson 对象

  { 
     "data":{

               "value": "AB1234"
            }
  }

我努力了

rapidjson::Document aJsonDocument;
aJsonDocument.SetObject();
rapidjson::Document::AllocatorType &aAllocator = aJsonDocument.GetAllocator();

rapidjson::Value aPsmJson(rapidjson::kStringType);
std::string aStr = "ABCDEF";
aPsmJson.SetString(aStr.c_str(), aAllocator);
aJsonDocument.AddMember("value", aPsmJson, aAllocator);

//jsonToString is a function to convert json document to string
std::string aInputJsonString = jsonToString(aJsonDocument);
std::cout << "Output: " << aInputJsonString ;

这给出了输出 {"value":"ABCDEF"}

Answer 1

您忘记创建一个Valuefor "data"：

string s = "ABCDEF";
Document d(kObjectType);
Value data(kObjectType);
Value value;
value.SetString(s.c_str(), d.GetAllocator());
data.AddMember("value", value, d.GetAllocator());
d.AddMember("data", data, d.GetAllocator());

std::cout << jsonToString(d);

输出：

{
    "data": {
        "value": "ABCDEF"
    }
}
