这是生成数组的
void test() { string info = "{"id":"1111111","cards":[0,1,2,3,4,5,6,7,8,9],"jiaoDiZhu":""}"; rapidjson::Document doc; doc.Parse<0>(info.c_str()); rapidjson::Value &dataArray = doc["cards"]; if (dataArray.IsArray()) { for (rapidjson::SizeType i = 0; i < dataArray.Size(); i++) { const rapidjson::Value& object = dataArray[i]; printf("%d ",object.GetInt()); } } }
void test() { //read json string updateInfo = "{"UpdateInfo":[{"url":"aaaa.ipa","platform":"ios"}]}"; rapidjson::Document doc; doc.Parse<0>(updateInfo.c_str()); rapidjson::Value &dataArray = doc["UpdateInfo"]; if (dataArray.IsArray()) { for (int i = 0; i < dataArray.Size(); i++) { const rapidjson::Value& object = dataArray[i]; string url = object["url"].GetString(); string platform = object["platform"].GetString(); } } //write json rapidjson::Document document; document.SetObject(); rapidjson::Document::AllocatorType& allocator = document.GetAllocator(); rapidjson::Value array(rapidjson::kArrayType); for (int i = 0; i < 10; i++) { rapidjson::Value object(rapidjson::kObjectType); object.AddMember("id", 1, allocator); object.AddMember("name", "test", allocator); object.AddMember("version", 1.01, allocator); object.AddMember("vip", true, allocator);
object.SetInt(i); array.PushBack(object, allocator); } document.AddMember("title", "PLAYER INFO", allocator); document.AddMember("players", array, allocator); rapidjson::StringBuffer buffer; rapidjson::Writer<rapidjson::StringBuffer> writer(buffer); document.Accept(writer); auto out = buffer.GetString(); log("out: %s", out); }
下面是单个的
void readTest() { char json[] = "{"carriorName":"日本电信","deviceName":"iPhone5,2","osName":"android","osVersion":"8.1","appId":"com.mmcshadow.doudizhu","versionName":"1.0","versionCode":"1.0","deviceId":"11111111"}"; rapidjson::Document d; d.Parse<0>(json); printf("%s ", d["carriorName"].GetString()); printf("%s ", json); }
void writeTest() { rapidjson::Document document; rapidjson::Document::AllocatorType& allocator = document.GetAllocator(); rapidjson::Value root(rapidjson::kObjectType); root.AddMember("name", "哥伦布啊", allocator); root.AddMember("gold",1234,allocator); rapidjson::StringBuffer buffer; rapidjson::Writer<rapidjson::StringBuffer> writer(buffer); root.Accept(writer); std::string reststring = buffer.GetString(); std::cout << reststring << std::endl; }
