saz2js

A utility to convert fiddler capture (.saz) to js object.

The code is inspired by node-saz-parser, updated to use yauzl instead of unzip.

Breaking Change: The release 1.0.0 and above allows you to control the content of sessions object, hence the api change. Now it parses the meta data as well.

Usage

1. install the package npm i saz2js
2. sample node script

const parser = require('saz2js');
 
const options = {
  req: true, // determines if the sessions object will contain request data
  res: true, // determines if the sessions object will contain response data
  meta: true // determines if the sessions object will contain meta information
}
 
parser('test.saz', options, function(err, sessions) {
  if (err) throw err;
  console.log(sessions);
});
 
// sessions object
{
  '09': {
    request: {
      method: 'GET',
      url: 'https://example.com?refresh=Refresh&url=true',
      protocol: 'HTTP/1.1',
      headers: {
        'Accepted': ''
        ...
      },
      content: 'body of request'
    },
    response: {
      protocol: 'HTTP/1.1',
      statusCode: '200',
      status: 'OK',
      headers: {
        ...
      },
      content: 'body of response'
    },
    meta: {
      _declaration: {
        _attributes: {
          version: "1.0",
          encoding: "utf-8"
        }
      },
      Session: {
        _attributes: {
          SID: "167",
          BitFlags: "19"
        },
      SessionTimers: {
          _attributes: {
            ClientConnected: "2019-06-07T11:24:55.8156275+10:00",
            ...
          }
        },
      PipeInfo: {
          _attributes: {
            CltReuse: "true",
            Reused: "true"
          }
        },
      SessionFlags: {
        SessionFlag: [
            {
              _attributes: {
                N: "x-processinfo",
                V: "chrome:6152"
              }
            },
            ...
          ]
        }
      }
    }
  }
  }
  ...
};
 

That's it, really!
