How to decode a recorded response

Question

How to ad-hoc decode / unpack the output generated by the sock recorder so that we can see the answer in text? I think we do not understand if the answer is gzipped and / or encoded

An object works when we load it into a knock, and our tests behave as we expect. To find out what the API has developed, we need to put the registration instructions in the implementation file.

We record and save JSON responses:

nock.recorder.rec({output_objects: true, dont_print: true});
JSON.stringify(nock.recorder.play())

And our file looks like this:

[ { "scope": "https://some.api.com:443", "method": "POST", "path": "/auth?key=some_key", "body": { "logonId": "[e-mail]", "logonPassword": "secret" }, "status": 400, "response": [ "1f8b0800000000000000458cbd6ac34010067b3fc5c735691263bb741344ec42f827420a492916692d1d9cb461f71c218cdf3d97266e6786b92d00c7aaa205290d1c59cd6d71bb3fff8b376939a1cd6abd7ac003cf89b97a5f96757efecc8ef9aede9fb2fc586455f5f55eeedca33db119757f0f5704266334a2ca4d44ec19170941263f76f06657b62dd6cb2af919ec9357cc7255f0cb403e4014df643689b6687d3b3e450c149b1e534f1113a3a71f868cb8f8c04b7ca48b8fa08efcf8ea16f75fa1776d91ee000000" ], "headers": { "cache-control": "no-store, no-cache, must-revalidate", "content-encoding": "gzip", "content-type": "application/json", "transfer-encoding": "chunked", "connection": "Close" } } ]

http- gzipped-, content-encoding. Nock .

json :

var zlib = require('zlib');
var fs = require('fs');
var argv = process.argv.slice(2);
var path = require('path');

var filename = path.resolve(argv[0]);
var file = fs.readFileSync(filename, { encoding: 'utf8' });
var cassettes = JSON.parse(file);

cassettes.forEach(function (cassette) {
  if (cassette.headers['content-encoding'] !== 'gzip') {
    return;
  }

  var response = new Buffer(cassette.response[0], 'hex');

  var contents = zlib.gunzipSync(response).toString('utf8');

  cassette.response = JSON.parse(contents);
  delete cassette.headers['content-encoding'];
});

fs.writeFileSync(filename, JSON.stringify(cassettes, null, 2), { encoding: 'utf8' });

, , gzip json. , , , , json.
