rapidjson解析和生成json-ag真人游戏

rapidjson学习

• rapidjson获取json数据键值对的key和value
  

std::string output = "";
output  = "deck: \n";
// deck
for (unsigned j = 0; j < (document["data"])["deck"].size(); j  ) {
  
	// deck内遍历
	for (rapidjson::value::constmemberiterator iter = ((document["data"])[i]["deck"])[j].memberbegin(); iter != ((document["data"])["deck"])[j].memberend(); iter  ) {
  
		rapidjson::value jkey;
		rapidjson::value jvalue;
		document::allocatortype allocator;
		jkey.copyfrom(iter->name, allocator);
		jvalue.copyfrom(iter->value, allocator);
		if (jkey.isstring()) {
  
			std::string name = jkey.getstring();
			std::string value = cocos2d::value(jvalue.getint()).asstring();
			output  = "    "    name   ':'   value   '\n';
		}
	}
	output  = "    ---\n";
}
output  = "---\n";

• rapidjson创建json
  场景：用户输入用户名和密码，然后将信息组合生成json

	rapidjson::document document;
	document.setobject();
	rapidjson::document::allocatortype& allocator = document.getallocator();
	
	//用户名
	rapidjson::value username(stringref(usernameinput->getstring().c_str()));
	document.addmember("username", username, allocator);
	
	//密码
	rapidjson::value password(stringref(passwordinput->getstring().c_str()));
	document.addmember("password", password, allocator);
	stringbuffer buffer;
	rapidjson::writer writer(buffer);
	document.accept(writer);
	//log("%s\n", buffer.getstring());
