iguana::json/xml 序列化框架

环境：win10  vs2017  c++17  boost

1、下载源码：https://github.com/qicosmos/iguana

2、创建工程，包含源码目录、boost库目录；boost库；c++17

//json结构模板
struct person
{
    std::string  name;
    int          age;
};
REFLECTION(person, name, age)

struct one_t
{
    int id;
};
REFLECTION(one_t, id);

struct two
{
    std::string name;
    one_t one;
    int age;
};
REFLECTION(two, name, one, age);

struct composit_t
{
    int a;
    std::vector<std::string> b;
    int c;
    std::map<int, int> d;
    std::unordered_map<int, int> e;
    double f;
    std::list<one_t> g;
};
REFLECTION(composit_t, a, b, c, d, e, f, g);

json 序列化

 
void test_json()
{
    person p;
    const char * json = "{ \"name\" : \"tom\", \"age\" : 20}";
    //string转对象
    auto r = iguana::json::from_json0(p, json);
    std::cout << p.age << " " << p.name << std::endl;

    iguana::string_stream ss;
    //对象转string
    iguana::json::to_json(ss, p);
    std::cout << ss.str() << std::endl;

    //复杂结构转string
    one_t one = { 2 };
    composit_t composit = { 1,{ "tom", "jack" }, 3,{ { 2,3 } },{ { 5,6 } }, 5.3,{ one } };
    iguana::string_stream sst;
    iguana::json::to_json(sst, composit);
    std::cout << sst.str() << std::endl;
    
    //string转对象
    const char* str_comp = R"({"b":["tom", "jack"], "a":1, "c":3, "e":{"3":4}, "d":{"2":3,"5":6},"f":5.3,"g":[{"id":1},{"id":2}])";
    composit_t comp;
    iguana::json::from_json0(comp, str_comp);
    std::cout << comp.a << " " << comp.f << std::endl;
}

xml序列化

void test_xml() 
{
    person p = { "admin", 20 };
    iguana::string_stream ss;
    iguana::xml::to_xml(ss, p);
    std::cout << ss.str() << std::endl;
    //<?xml version = "1.0" encoding="UTF-8"><name>admin</name><age>20</age>

    ss.clear();
    two t = { "test", {2}, 4 };
    iguana::xml::to_xml(ss, t);
    auto result = ss.str();
    std::cout << result << std::endl;
    //<?xml version = "1.0" encoding="UTF-8"><name>test</name><one><id>2</id></one><age>4</age>
    
    std::string xml = "<?xml version=\"1.0\" encoding=\"UTF-8\">  <name>buke</name> <one><id>1</id></one>  <age>2</age>";
    two t1;
    iguana::xml::from_xml(t1, xml.data(), xml.length());
    std::cout << t1.name << std::endl;
}
