Number value changes on JSON.parse( )

问题

I'm using Node/Express to make API requests to the unofficial Vine API.

The data that the GET https://api.vineapp.com/users/search/ route returns changes on parsing.

My code is the following:

request({ url: 'https://api.vineapp.com/users/search/' + username }, function (error, response, body) {
  if (error) throw new Error(error);

  console.log(typeof body,'UNPARSED BODY:', body);

  body = JSON.parse(body);

  console.log(typeof body,'PARSED BODY:', JSON.stringify(body, null, 2));

  cb(null, body)
});

This is what is returns: The data.records.userId changes on parsing.

Why does this happen? Am I missing something here? Why would they do that?

回答1:

The number is too high for the JSON parser

Info about the highest possible value in javascript:
What is JavaScript's highest integer value that a Number can go to without losing precision?

There is a solution provided here:
node.js is there any proper way to parse JSON with large numbers? (long, bigint, int64)
