Methods

request(options)

Returns the response object.

  myChain()
    .request('http://jsonip.com/')
    .tap(function (err, response) {
      console.log(response.statusCode); /* > 200 */
      console.log(response.body); /* > '{"ip":"123.45.67.89","about":"/about","Pro!":"http://getjsonip.com"}' */
    });
 
  myChain()
    .request({
      url: 'http://jsonip.com/',
      json: true
    })
    .tap(function (err, response) {
      console.log(response.statusCode); /* > 200 */
      console.log(response.body); /* > {ip: '123.45.67.89', about: '/about', 'Pro!': 'http://getjsonip.com' } */
    });

@param {string|Object|Function|undefined} options options for the request. A string or object param is passed directly to request.js. A function is executed with the chain as context (e.g. it has access to this.previousResult()), and the returned value is passed to request.js. If no parameter is passed, the previousResult() is passed to request.js.

requestBody(options)

Same as request(options), except returns the response body (or errors on a non-200 response).

  myChain()
    .requestBody('http://jsonip.com/')
    .tap(function (err, response) {
      console.log(response); /* > '{"ip":"123.45.67.89","about":"/about","Pro!":"http://getjsonip.com"}' */
    });

requestJson(options)

Same as requestBody(options), except returns the body parsed as JSON.

  myChain()
    .requestJson('http://jsonip.com/')
    .tap(function (err, response) {
      console.log(response); /* > {ip: '123.45.67.89', about: '/about', 'Pro!': 'http://getjsonip.com' } */
    });
