#rapidjson 嵌套json

本文介绍了如何使用RapidJson库在C++中创建包含嵌套数组的JSON文本。示例代码展示了如何构建JSON对象，并输出生成的JSON字符串。

上篇博文里我通过RapidJson解析了嵌套的json文本，那么本文章是RapidJson创建嵌套数组Json文本。

代码：

#include "rapidjson/document.h"

#include "rapidjson/writer.h"

#include "rapidjson/stringbuffer.h"

#include

using namespace rapidjson;

int main() {

// 1. Parse a JSON string into DOM.

const char* json ="{\"Info\":[{\"lots\":10,\"order_algorithm\":\"01\",\"buy_close\":9000,\"spread_shift\":0,\"position_b_sell\":0,\"position_a_buy_today\":0,\"position_a_buy_yesterday\":0,\"sell_open\":-9000,\"list_instrument_id\":[\"rb1705\",\"rb1701\"],\"position_b_buy_today\":0,\"buy_open\":-9000,\"position_a_sell_yesterday\":0,\"strategy_id\":\"02\",\"position_b_buy\":0,\"a_wait_price_tick\":1,\"trade_model\":\"boll_reversion\",\"b_wait_price_tick\":0,\"sell_close\":9000,\"only_close\":0,\"order_action_limit\":400,\"is_active\":1,\"lots_batch\":1,\"position_a_sell\":0,\"position_b_buy_yesterday\":0,\"user_id\":\"063802\",\"position_a_buy\":0,\"trader_id\":\"1601\",\"position_a_sell_today\":0,\"stop_loss\":0,\"position_b_sell_today\":0,\"position_b_sell_yesterday\":0,\"on_off\":0},{\"lots\":20,\"order_algorithm\":\"02\",\"buy_close\":9000,\"spread_shift\":0,\"position_b_sell\":0,\"position_a_buy_today\":0,\"position_a_buy_yesterday\":0,\"sell_open\":-9000,\"list_instrument_id\":[\"ni1705\",\"ni1701\"],\"position_b_buy_today\":0,\"buy_open\":-9000,\"position_a_sell_yesterday\":0,\"strategy_id\":\"01\",\"position_b_buy\":0,\"a_wait_price_tick\":1,\"trade_model\":\"boll_reversion\",\"b_wait_price_tick\":0,\"sell_close\":9000,\"only_close\":0,\"order_action_limit\":400,\"is_active\":1,\"lots_batch\":1,\"position_a_sell\":0,\"position_b_buy_yesterday\":0,\"user_id\":\"063802\",\"position_a_buy\":0,\"trader_id\":\"1601\",\"position_a_sell_today\":0,\"stop_loss\":0,\"position_b_sell_today\":0,\"position_b_sell_yesterday\":0,\"on_off\":0}],\"MsgSendFlag\":0,\"MsgErrorReason\":\"IDorpassworderror\",\"MsgRef\":1,\"MsgType\":3,\"MsgResult\":0}";

//std::cout << json << std::endl;

//std::cout << "\n" << std::endl;

std::cout << "|==================|" << std::endl;

std::cout << "||rapidjson output||" << std::endl;

std::cout << "|==================|" << std::endl;

Document doc;

doc.SetObject();

rapidjson::Document::AllocatorType& allocator = doc.GetAllocator();

doc.AddMember("MsgSendFlag", 1, allocator);

doc.AddMember("MsgErrorReason", "IDorpassworderror", allocator);

doc.AddMember("MsgRef", 1, allocator);

rapidjson::Value info_array(rapidjson::kArrayType);
