我想請執行以下操作：節點API請求
創建新對象「評估」
獲得來自aclient數據並將其保存到該對象
使POST請求來自「評估」對象的數據
向「評估」對象添加請求響應
保存到蒙戈Db的
承滴盤看起來不錯，但我不能從POST請求對象「評估」添加響應數據。我可以訪問它。但我不能從第二個請求添加額外的數據。
res.on("end", function() {
//console.log(body.toString());
body = JSON.parse(Buffer.concat(chunks));
console.log(body.value) // does work
evaluation.result.date = body.date; // does not work
evaluation.result.value = body.value; // does not work
console.log(evaluation.street); //does work
});

const Evaluation = module.exports = mongoose.model('Evaluation', EvaluationSchema);
// Get Books
module.exports.getAll = (callback, limit) => {

}
沒有人有任何想法嗎？ –
