You can create a JSON value (deserialization) by appending _json to a string literal: // create object from string literal json j = "{ \"happy\": true, \"pi\": 3.141 }"_json; // or even nicer with a raw string literal auto j2 = R"( { "happy": true, "pi": 3.141 } )"...
将其转换为字符串,而不是使用运算符<<序列化到另一个json。

nlomann::json 可以使用 get<typename BasicJsonType>() const 将Json 对象转换为大多数标准 STL 容器 例子: // Raw string to json type auto j = R"( { "foo" : { "bar" : 1, "baz" : 2 } } )"_json; // find object and convert to map std::map<std::string, int> m = j.at(...
nlohmann是一个用起来很方便的json c++ 库,但是还得自己写一堆代码。特别是如果原来的结构较多,得改一堆, 可以用llvm cpp parser来生成这样的代码。 主函数 static void Main(string[] args) { var p = @"J:\fy\inc\"; var files = new List<string>() ...
Other aspects were not so important to us: Memory efficiency. Each JSON object has an overhead of one pointer (the maximal size of a union) and one enumeration element (1 byte). The default generalization uses the following C++ data types:std::stringfor strings,int64_t,uint64_tordoublefor...
