folly json 學習

folly json

json 生成

• 代碼

    std::string json = folly::toJson(
    	folly::dynamic::object
    	("type", "login-app")
    	("os", "windows")
    	("uuid", "123456")
    	("time", 112233)
    	("status", false)
    );
  

• 結果

    json : {"uuid":"123456","os":"windows","type":"login-app"}
  

json 解析

• 代碼

    folly::dynamic jobj = folly::parseJson(json);
  
    std::string os = jobj["os"].asString();
    std::string type = jobj["type"].asString();
    std::string uuid = jobj["uuid"].asString();
    int  time = jobj["time"].asInt();
    bool status = status = jobj["status"].asBool();
  
    std::cout << " os     " << os << std::endl;
    std::cout << " type   " << type << std::endl;
    std::cout << " uuid   " << uuid << std::endl;
    std::cout << " time   " << time << std::endl;
    std::cout << " status " << status << std::endl;
  

• 結果

     os     windows
     type   login-app
     uuid   123456
     time   112233
     status 0
