用JSONCPP格式化以下数据，我需要C++代码：{ "appkey": "a20d86c00ff80c14e05305660f0adc99", "timestamp": "1585550060", "sign": "3507fffd6121603a600732e72dd8b9b1", "workStationCode": "1101-pack-zdx", "MO": "200000031624", "WO": "1110 线-200000031624-PACK", "machineNo": "设备编号", "laneNo": "轨道", "fixtureNo": "夹具二维码", "staffNo": "操作员工号", "workTime": "2022-04-01 09:30:12", "finishTime": "2022-04-01 09:33:15", "pcList": [ { "seq": "1", "barcode": "小板二维码 1", "barcode2": "商标二维码", "progName": "LW-[306L033(VB100-8SP1)-01-B]-B07(T1A)-XN-V1.0", "productModel": "VB100-8SP1", "sn": "1234", "productDate": "2022-04-01", "procName": "性能", "procCode": "XN", "status": "PASS", "NGReason": "", "dataList": [ { "seq": "1", "testItem": "charge_v", "testName": "充电电压", "testResult": "PASS", "testUnits": "V", "dataValue": "4.3", "upperLimit": "4.5", "lowerLimit": "4.2" } ], "charList": [ { "seq": "1", "testItem": "read_sn", "testName": "读 SN", "testResult": "PASS", "charValue": "G8V10926394273" } ] } ] }

以下是用JSONCPP格式化数据的C代码：

pcList.append(pc);
root["pcList"] = pcList;

Json::StreamWriterBuilder builder;
builder["indentation"] = "\t";
std::unique_ptr<Json::StreamWriter> writer(builder.newStreamWriter());
writer->write(root, &std::cout);

return ;
}
