如何在nodejs中發送api資料例如作為描述框給出

假設我有一個物件陣列：

它將多個值存盤在一個變數中。該物件可以包含用戶名、金額等。實際上，我將資料的相同物件存盤在單個物件中，例如描述中的定義。所以，幫我每個人都可以解決這個問題。請解決這個問題。

    {
        "id": 14,
        "Username": "rajesh",
        "Amount": "1200",

However, I can't seem to get an array that looks like this

```{
    "john$123": [
        {

            "Username": "john$123",

I have been able to make some sort of headway, but can not quite get the exact result I need. Any guidance is greatly appreciated, thanks!

不確定我是否理解正確，但您只想獲取具有特定用戶名的用戶的資訊是否正確？

如果是這樣，那么您可以在第一個物件上使用 .filter() ，如下所示

let array = [] //your original array
let username = "rajesh" //the username whose info you want to get
let userData = array.filter(results => results.Username.toLowerCase() === username.toLowerCase())
console.log(userData) //this will contain all the elements that had their username the same as the username in the username variable (case insensitive)

//do stuff with the new filtered user data

現在，如果您希望資料為 json，密鑰為用戶名，您可以這樣做

let returnData = {}
returnData[username] = userData
return returnData
