解析多级 JSON Output Javascript

Question

EDITED WITH UPDATED OUTPUT I was able to use the request module which now provides me with verified standard JSON output. See below output:

 const respBody = { "items": [ { "id": "T0lDX0J1aWxkX0FydGlmYWN0czpmODk4YjM5MDNjYjk5YzU5NjgzNTk3ZWRjNWFmZjliYw", "repository": "Build_Artifacts", "format": "raw", "group": "/", "name": "myFile.zip", "version": null, "assets": [ { "downloadUrl": "http://localhost:8081/repository/Build_Artifacts/myFile.zip", "path": "myFile.zip", "id": "T0lDX0J1aWxkX0FydGlmYWN0czphNDc1N2JjYWE2MmI2MzA2MDdlMTA1NGE4NTk1MDQ1OQ", "repository": "OIC_Build_Artifacts", "format": "raw", "checksum": { "sha1": "040e517528c05ca335a38e98c7ab8673773314bd", "sha512": "652e624873da778dce4bc417cacfead12bdd2ad01e9f7f77cba80270caa0f99caa09d4fb53f584a4da9991186f78bd7b55da1e4ed3f22e026b8333dd332b3b83", "sha256": "b66805d15702505f708b90f6e1169c79390d59b9f8cadc9ab1852f48eeabbfe2", "md5": "60fdd406e026330c2cfbec3e15e05414" } } ] }] }

I was able to parse what I needed with "respbody.items[0].name"

That isn't the JSON standard covered by JSON.parse() . The easiest way to get the object would be to use eval() :

let array = global
  .eval("[{foo: 'bar', name: 'value'}]")
  .map(item => {
    return {name: item.name};
  });

// will output: [{name: "value"}]
console.log(array);

But that would be totally unsave, like MDN writes:

Warning: Executing JavaScript from a string is an enormous security risk. It is far too easy for a bad actor to run arbitrary code when you use eval() . See Never use eval()! , below.

A better way would be using JSON5 , which also supports the object notation of ES5 JavaScript. It is also available over npm:

https://www.npmjs.com/package/json5

For more information about that see the question " Parsing "relaxed" JSON without eval ".
