Is it possible to verify the authenticity of JSON data retrieved from

I'm currently working on validating JSON input from users and came across a challenge. I've found a way to check if the text a user enters is valid JSON using a simple function, like below:

function IsJsonString(str) {
    try {
        JSON.parse(str);
    } catch (e) {
        return false;
    }
    return true;
}

However, my issue lies with JSON data coming from Mongo, which often includes objects like ObjectId and ISODate, making it look like this:

{
    "_id" : ObjectId("5733b42c66beadec3cbcb9a4"),
    "date" : ISODate("2016-05-11T22:37:32.341Z"),
    "name" : "KJ"
}

As this format isn't considered valid JSON, I'm trying to figure out how to validate JSON while still accommodating such structures. Any ideas or suggestions would be greatly appreciated!

Instead of calling functions directly, you can replace them with strings in this way:

function IsJsonLikeString(str) {
  str = str.replace(/(\w+)\("([^"]+)"\)/g, '"$1(\"$2\")"');
  try {
    JSON.parse(str);
  } ...

/(\w+)\("([^"]+)"\)/g
    1st Capturing group (\w+)
        \w+ match any word character [a-zA-Z0-9_]
            Quantifier: + Between one and unlimited times, as many times as possible, giving back as needed [greedy]
    \( matches the character ( literally
    " matches the characters " literally
    2nd Capturing group ([^"]+)
        [^"]+ match a single character not present in the list below
            Quantifier: + Between one and unlimited times, as many times as possible, giving back as needed [greedy]
            " a single character in the list " literally (case sensitive)
    " matches the characters " literally
    \) matches the character ) literally
    g modifier: global. All matches (don't return on first match)

Answer №2

The challenge lies not in validating JSON, but rather in ensuring that the database can properly process the input data. It's important to confirm that the syntax is accurate, and then test the data within the mongo collection to identify any potential issues.

For more information, refer to MongoDB db.collection.explain() to validate the Mongo query.
