如何将 DynamoDB JSON 对象转换为 JavaScript 中的常规对象？

示例 DynamoDB 对象:

{
 "key1": {
  "S": "val1"
 },
 "key2": {
  "S": "val2"
 },
 "key3": {
  "M": {
   "key4": {
    "M": {
     "key5": {
      "S": "val5"
     }
    }
   }
  }
 },
 "key6": {
  "S": "val6"
 }
}

预期输出:

{
 "key1": "val1",
 "key2": "val2",
 "key3": {
  "key4": {
   "key5": "val5"
  }
 },
 "key6": "val6"
}

最佳答案

您可以使用 unmarshall function in the @aws-sdk/util-dynamodb library .

const { unmarshall } = require("@aws-sdk/util-dynamodb");

const regularObject = unmarshall(dynamoObject);

console.log(regularObject); // Will output converted object
