Request digest client in Node.js

Perform a client request (http) with a digest authentication, a simple node http digest client.

Disclaimer

Only tested against one server and spec is not followed fully. It works for me and for what I am doing. I often try to improve this npm and I answer to your pull-request and issue ASAP in order to improve your experience with this package. Pay attention, it only works with MD5 algorithm currently.

Usage (callback)

var digestRequest = require('request-digest')('username', 'password');
digestRequest.request({
  host: 'http://test.com',
  path: '/api/v1/test.json',
  port: 80,
  method: 'GET',
  headers: {
    'Custom-Header': 'OneValue',
    'Other-Custom-Header': 'OtherValue'
  }
}, function (error, response, body) {
  if (error) {
    throw error;
  }

  console.log(body);
});

Usage (promise, only >= 1.0.0)

GET example

var digestRequest = require('request-digest')('username', 'password');
digestRequest.requestAsync({
  host: 'http://test.com',
  path: '/api/v1/test.json',
  port: 80,
  method: 'GET',
  excludePort: false,
  headers: {
    'Custom-Header': 'OneValue',
    'Other-Custom-Header': 'OtherValue'
  }
})
.then(function (response) {
  console.log(response.body);
})
.catch(function (error) {
  console.log(error.statusCode);
  console.log(error.body);
});

The digest client will make one request to the server, authentication response is calculated and then the request is made again. Hopefully you will then be authorized.

If you don't want to specify or to use a specific port. Default port value is 80 but if you set the option excludePort to true it won't add a port to your URL.

POST example

Following is a POST with JSON body example.

var digestRequest = require('request-digest')('username', 'password');
digestRequest.requestAsync({
  host: 'http://test.com',
  path: '/api/v1/test',
  port: 80,
  method: 'POST',
  json: true,
  body: {
     myData: 'test'
  },
  headers: {
        'Content-Type': 'application/json'
      }
})
.then(function (response) {
  console.log(response.body);
})
.catch(function (error) {
  console.log(error.statusCode);
  console.log(error.body);
});

Return object

• Response object :

response = {
  response,
  body
};

• Error object :

error = {
  response,
  body,
  statusCode
};

Versions:

Pay attention, after version 1.0.0 I have implemented promise support and add a better support of errors with statusCode >= 400.
