request(options, callback)

The first argument can be either a url or an options object. The only required option is uri; all others are optional.

uri || url - fully qualified uri or a parsed url object from url.parse()
baseUrl - fully qualified uri string used as the base url. Most useful with request.defaults, for example when you want to do many requests to the same domain. If baseUrl is https://example.com/api/, then requesting /end/point?test=true will fetch https://example.com/api/end/point?test=true. When baseUrl is given, uri must also be a string.
method - http method (default: "GET")
headers - http headers (default: {})
qs - object containing querystring values to be appended to the uri
qsParseOptions - object containing options to pass to the qs.parse method. Alternatively pass options to the querystring.parse method using this format {sep:';', eq:':', options:{}}
qsStringifyOptions - object containing options to pass to the qs.stringify method. Alternatively pass options to the querystring.stringify method using this format {sep:';', eq:':', options:{}}. For example, to change the way arrays are converted to query strings using the qs module pass the arrayFormat option with one of indices|brackets|repeat
useQuerystring - If true, use querystring to stringify and parse querystrings, otherwise use qs (default: false). Set this option to true if you need arrays to be serialized as foo=bar&foo=baz instead of the default foo[0]=bar&foo[1]=baz.
body - entity body for PATCH, POST and PUT requests. Must be a Buffer, String or ReadStream. If json is true, then body must be a JSON-serializable object.
form - when passed an object or a querystring, this sets body to a querystring representation of value, and adds Content-type: application/x-www-form-urlencoded header. When passed no options, a FormData instance is returned (and is piped to request). See "Forms" section above.
formData - Data to pass for a multipart/form-data request. See Forms section above.
multipart - array of objects which contain their own headers and body attributes. Sends a multipart/related request. See Forms section above.
Alternatively you can pass in an object {chunked: false, data: []} where chunked is used to specify whether the request is sent in chunked transfer encoding In non-chunked requests, data items with body streams are not allowed.
preambleCRLF - append a newline/CRLF before the boundary of your multipart/form-data request.
postambleCRLF - append a newline/CRLF at the end of the boundary of your multipart/form-data request.
json - sets body to JSON representation of value and adds Content-type: application/json header. Additionally, parses the response body as JSON.
jsonReviver - a reviver function that will be passed to JSON.parse() when parsing a JSON response body.
jsonReplacer - a replacer function that will be passed to JSON.stringify() when stringifying a JSON request body.
auth - A hash containing values user || username, pass || password, and sendImmediately (optional). See documentation above.
oauth - Options for OAuth HMAC-SHA1 signing. See documentation above.
hawk - Options for Hawk signing. The credentials key must contain the necessary signing info, see hawk docs for details.
aws - object containing AWS signing information. Should have the properties key, secret. Also requires the property bucket, unless you’re specifying your bucket as part of the path, or the request doesn’t use a bucket (i.e. GET Services). If you want to use AWS sign version 4 use the parameter sign_version with value 4 otherwise the default is version 2. Note: you need to npm install aws4 first.
httpSignature - Options for the HTTP Signature Scheme using Joyent's library. The keyId and key properties must be specified. See the docs for other options.
followRedirect - follow HTTP 3xx responses as redirects (default: true). This property can also be implemented as function which gets response object as a single argument and should return true if redirects should continue or false otherwise.
followAllRedirects - follow non-GET HTTP 3xx responses as redirects (default: false)
maxRedirects - the maximum number of redirects to follow (default: 10)
removeRefererHeader - removes the referer header when a redirect happens (default: false). Note: if true, referer header set in the initial request is preserved during redirect chain.
encoding - Encoding to be used on setEncoding of response data. If null, the body is returned as a Buffer. Anything else (including the default value of undefined) will be passed as the encoding parameter to toString() (meaning this is effectively utf8 by default). (Note: if you expect binary data, you should set encoding: null.)
gzip - If true, add an Accept-Encoding header to request compressed content encodings from the server (if not already present) and decode supported content encodings in the response. Note: Automatic decoding of the response content is performed on the body data returned through request (both through the request stream and passed to the callback function) but is not performed on the response stream (available from the response event) which is the unmodified http.IncomingMessage object which may contain compressed data. See example below.
jar - If true, remember cookies for future use (or define your custom cookie jar; see examples section)
agent - http(s).Agent instance to use
agentClass - alternatively specify your agent's class name
agentOptions - and pass its options. Note: for HTTPS see tls API doc for TLS/SSL options and the documentation above.
forever - set to true to use the forever-agent Note: Defaults to http(s).Agent({keepAlive:true}) in node 0.12+
pool - An object describing which agents to use for the request. If this option is omitted the request will use the global agent (as long as your options allow for it). Otherwise, request will search the pool for your custom agent. If no custom agent is found, a new agent will be created and added to the pool. Note: pool is used only when the agent option is not specified.
A maxSockets property can also be provided on the pool object to set the max number of sockets for all agents created (ex: pool: {maxSockets: Infinity}).
Note that if you are sending multiple requests in a loop and creating multiple new pool objects, maxSockets will not work as intended. To work around this, either use request.defaults with your pool options or create the pool object with the maxSockets property outside of the loop.
timeout - Integer containing the number of milliseconds to wait for a server to send response headers (and start the response body) before aborting the request. Note that if the underlying TCP connection cannot be established, the OS-wide TCP connection timeout will overrule the timeout option (the default in Linux can be anywhere from 20-120 seconds).
localAddress - Local interface to bind for network connections.
proxy - An HTTP proxy to be used. Supports proxy Auth with Basic Auth, identical to support for the url parameter (by embedding the auth info in the uri)
strictSSL - If true, requires SSL certificates be valid. Note: to use your own certificate authority, you need to specify an agent that was created with that CA as an option.
tunnel - controls the behavior of HTTP CONNECT tunneling as follows:
undefined (default) - true if the destination is https, false otherwise
true - always tunnel to the destination by making a CONNECT request to the proxy
false - request the destination as a GET request.
proxyHeaderWhiteList - A whitelist of headers to send to a tunneling proxy.
proxyHeaderExclusiveList - A whitelist of headers to send exclusively to a tunneling proxy and not to destination.
time - If true, the request-response cycle (including all redirects) is timed at millisecond resolution, and the result provided on the response's elapsedTime property. The responseStartTime property is also available to indicate the timestamp when the response begins.
har - A HAR 1.2 Request Object, will be processed from HAR format into options overwriting matching values (see the HAR 1.2 section for details)
callback - alternatively pass the request's callback in the options object
The callback argument gets 3 arguments:

An error when applicable (usually from http.ClientRequest object)
An http.IncomingMessage object
The third is the response body (String or Buffer, or JSON object if the json option is supplied)
