It supports HTTPS and follows redirects by default.\n\n```javascript\nvar request = require('request');\nrequest('http://www.google.com', function (error, response, body) {\n  if (!error && response.statusCode == 200) {\n    console.log(body) // Print the google web page.\n  }\n})\n```\n\n## Streaming\n\nYou can stream any response to a file stream.\n\n```javascript\nrequest('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png'))\n```\n\nYou can also stream a file to a PUT or POST request. This method will also check the file extension against a mapping of file extensions to content-types (in this case `application/json`) and use the proper `content-type` in the PUT request (if the headers don’t already provide one).\n\n```javascript\nfs.createReadStream('file.json').pipe(request.put('http://mysite.com/obj.json'))\n```\n\nRequest can also `pipe` to itself. When doing so, `content-type` and `content-length` are preserved in the PUT headers.\n\n```javascript\nrequest.get('http://google.com/img.png').pipe(request.put('http://mysite.com/img.png'))\n```\n\nNow let’s get fancy.\n\n```javascript\nhttp.createServer(function (req, resp) {\n  if (req.url === '/doodle.png') {\n    if (req.method === 'PUT') {\n      req.pipe(request.put('http://mysite.com/doodle.png'))\n    } else if (req.method === 'GET' || req.method === 'HEAD') {\n      request.get('http://mysite.com/doodle.png').pipe(resp)\n    }\n  }\n})\n```\n\nYou can also `pipe()` from `http.ServerRequest` instances, as well as to `http.ServerResponse` instances. The HTTP method, headers, and entity-body data will be sent. Which means that, if you don't really care about security, you can do:\n\n```javascript\nhttp.createServer(function (req, resp) {\n  if (req.url === '/doodle.png') {\n    var x = request('http://mysite.com/doodle.png')\n    req.pipe(x)\n    x.pipe(resp)\n  }\n})\n```\n\nAnd since `pipe()` returns the destination stream in ≥ Node 0.5.x you can do one line proxying. :)\n\n```javascript\nreq.pipe(request('http://mysite.com/doodle.png')).pipe(resp)\n```\n\nAlso, none of this new functionality conflicts with requests previous features, it just expands them.\n\n```javascript\nvar r = request.defaults({'proxy':'http://localproxy.com'})\n\nhttp.createServer(function (req, resp) {\n  if (req.url === '/doodle.png') {\n    r.get('http://google.com/doodle.png').pipe(resp)\n  }\n})\n```\n\nYou can still use intermediate proxies, the requests will still follow HTTP forwards, etc.\n\n## Proxies\n\nIf you specify a `proxy` option, then the request (and any subsequent\nredirects) will be sent via a connection to the proxy server.\n\nIf your endpoint is an `https` url, and you are using a proxy, then\nrequest will send a `CONNECT` request to the proxy server *first*, and\nthen use the supplied connection to connect to the endpoint.\n\nThat is, first it will make a request like:\n\n```\nHTTP/1.1 CONNECT endpoint-server.com:80\nHost: proxy-server.com\nUser-Agent: whatever user agent you specify\n```\n\nand then the proxy server make a TCP connection to `endpoint-server`\non port `80`, and return a response that looks like:\n\n```\nHTTP/1.1 200 OK\n```\n\nAt this point, the connection is left open, and the client is\ncommunicating directly with the `endpoint-server.com` machine.\n\nSee (the wikipedia page on HTTP\nTunneling)[http://en.wikipedia.org/wiki/HTTP_tunnel] for more\ninformation.\n\nBy default, when proxying `http` traffic, request will simply make a\nstandard proxied `http` request.  This is done by making the `url`\nsection of the initial line of the request a fully qualified url to\nthe endpoint.\n\nFor example, it will make a single request that looks like:\n\n```\nHTTP/1.1 GET http://endpoint-server.com/some-url\nHost: proxy-server.com\nOther-Headers: all go here\n\nrequest body or whatever\n```\n\nBecause a pure \"http over http\" tunnel offers no additional security\nor other features, it is generally simpler to go with a\nstraightforward HTTP proxy in this case.  However, if you would like\nto force a tunneling proxy, you may set the `tunnel` option to `true`.\n\nIf you are using a tunneling proxy, you may set the\n`proxyHeaderWhiteList` to share certain headers with the proxy.\n\nBy default, this set is:\n\n```\naccept\naccept-charset\naccept-encoding\naccept-language\naccept-ranges\ncache-control\ncontent-encoding\ncontent-language\ncontent-length\ncontent-location\ncontent-md5\ncontent-range\ncontent-type\nconnection\ndate\nexpect\nmax-forwards\npragma\nproxy-authorization\nreferer\nte\ntransfer-encoding\nuser-agent\nvia\n```\n\nNote that, when using a tunneling proxy, the `proxy-authorization`\nheader is *never* sent to the endpoint server, but only to the proxy\nserver.  All other headers are sent as-is over the established\nconnection.\n\n## UNIX Socket \n\n`request` supports the `unix://` protocol for all requests. The path is assumed to be absolute to the root of the host file system. \n\nHTTP paths are extracted from the supplied URL by testing each level of the full URL against net.connect for a socket response.\n\nThus the following request will GET `/httppath` from the HTTP server listening on `/tmp/unix.socket`\n\n```javascript\nrequest.get('unix://tmp/unix.socket/httppath')\n```\n\n## Forms\n\n`request` supports `application/x-www-form-urlencoded` and `multipart/form-data` form uploads. For `multipart/related` refer to the `multipart` API.\n\nURL-encoded forms are simple.\n\n```javascript\nrequest.post('http://service.com/upload', {form:{key:'value'}})\n// or\nrequest.post('http://service.com/upload').form({key:'value'})\n```\n\nFor `multipart/form-data` we use the [form-data](https://github.com/felixge/node-form-data) library by [@felixge](https://github.com/felixge). You don’t need to worry about piping the form object or setting the headers, `request` will handle that for you.\n\n```javascript\nvar r = request.post('http://service.com/upload', function optionalCallback (err, httpResponse, body) {\n  if (err) {\n    return console.error('upload failed:', err);\n  }\n  console.log('Upload successful!  Server responded with:', body);\n})\nvar form = r.form()\nform.append('my_field', 'my_value')\nform.append('my_buffer', new Buffer([1, 2, 3]))\nform.append('my_file', fs.createReadStream(path.join(__dirname, 'doodle.png')))\nform.append('remote_file', request('http://google.com/doodle.png'))\n\n// Just like always, `r` is a writable stream, and can be used as such (you have until nextTick to pipe it, etc.)\n// Alternatively, you can provide a callback (that's what this example does — see `optionalCallback` above).\n```\n\n## HTTP Authentication\n\n```javascript\nrequest.get('http://some.server.com/').auth('username', 'password', false);\n// or\nrequest.get('http://some.server.com/', {\n  'auth': {\n    'user': 'username',\n    'pass': 'password',\n    'sendImmediately': false\n  }\n});\n// or\nrequest.get('http://some.server.com/').auth(null, null, true, 'bearerToken');\n// or\nrequest.get('http://some.server.com/', {\n  'auth': {\n    'bearer': 'bearerToken'\n  }\n});\n```\n\nIf passed as an option, `auth` should be a hash containing values `user` || `username`, `pass` || `password`, and `sendImmediately` (optional).  The method form takes parameters `auth(username, password, sendImmediately)`.\n\n`sendImmediately` defaults to `true`, which causes a basic authentication header to be sent.  If `sendImmediately` is `false`, then `request` will retry with a proper authentication header after receiving a `401` response from the server (which must contain a `WWW-Authenticate` header indicating the required authentication method).\n\nNote that you can also use for basic authentication a trick using the URL itself, as specified in [RFC 1738](http://www.ietf.org/rfc/rfc1738.txt). \nSimply pass the `user:password` before the host with an `@` sign.\n\n```javascript\nvar username = 'username',\n    password = 'password',\n    url = 'http://' + username + ':' + password + '@some.server.com';\n\nrequest({url: url}, function (error, response, body) {\n   // Do more stuff with 'body' here\n});\n```\n\nDigest authentication is supported, but it only works with `sendImmediately` set to `false`; otherwise `request` will send basic authentication on the initial request, which will probably cause the request to fail.\n\nBearer authentication is supported, and is activated when the `bearer` value is available. The value may be either a `String` or a `Function` returning a `String`. Using a function to supply the bearer token is particularly useful if used in conjuction with `defaults` to allow a single function to supply the last known token at the time or sending a request or to compute one on the fly.\n\n## OAuth Signing\n\n```javascript\n// Twitter OAuth\nvar qs = require('querystring')\n  , oauth =\n    { callback: 'http://mysite.com/callback/'\n    , consumer_key: CONSUMER_KEY\n    , consumer_secret: CONSUMER_SECRET\n    }\n  , url = 'https://api.twitter.com/oauth/request_token'\n  ;\nrequest.post({url:url, oauth:oauth}, function (e, r, body) {\n  // Ideally, you would take the body in the response\n  // and construct a URL that a user clicks on (like a sign in button).\n  // The verifier is only available in the response after a user has\n  // verified with twitter that they are authorizing your app.\n  var access_token = qs.parse(body)\n    , oauth =\n      { consumer_key: CONSUMER_KEY\n      , consumer_secret: CONSUMER_SECRET\n      , token: access_token.oauth_token\n      , verifier: access_token.oauth_verifier\n      }\n    , url = 'https://api.twitter.com/oauth/access_token'\n    ;\n  request.post({url:url, oauth:oauth}, function (e, r, body) {\n    var perm_token = qs.parse(body)\n      , oauth =\n        { consumer_key: CONSUMER_KEY\n        , consumer_secret: CONSUMER_SECRET\n        , token: perm_token.oauth_token\n        , token_secret: perm_token.oauth_token_secret\n        }\n      , url = 'https://api.twitter.com/1.1/users/show.json?'\n      , params =\n        { screen_name: perm_token.screen_name\n        , user_id: perm_token.user_id\n        }\n      ;\n    url += qs.stringify(params)\n    request.get({url:url, oauth:oauth, json:true}, function (e, r, user) {\n      console.log(user)\n    })\n  })\n})\n```\n\n## Custom HTTP Headers\n\nHTTP Headers, such as `User-Agent`, can be set in the `options` object.\nIn the example below, we call the github API to find out the number\nof stars and forks for the request repository. This requires a\ncustom `User-Agent` header as well as https.\n\n```javascript\nvar request = require('request');\n\nvar options = {\n\turl: 'https://api.github.com/repos/mikeal/request',\n\theaders: {\n\t\t'User-Agent': 'request'\n\t}\n};\n\nfunction callback(error, response, body) {\n\tif (!error && response.statusCode == 200) {\n\t\tvar info = JSON.parse(body);\n\t\tconsole.log(info.stargazers_count + \" Stars\");\n\t\tconsole.log(info.forks_count + \" Forks\");\n\t}\n}\n\nrequest(options, callback);\n```\n\n## request(options, callback)\n\nThe first argument can be either a `url` or an `options` object. The only required option is `uri`; all others are optional.\n\n* `uri` || `url` - fully qualified uri or a parsed url object from `url.parse()`\n* `qs` - object containing querystring values to be appended to the `uri`\n* `method` - http method (default: `\"GET\"`)\n* `headers` - http headers (default: `{}`)\n* `body` - entity body for PATCH, POST and PUT requests. Must be a `Buffer` or `String`.\n* `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; charset=utf-8` header. When passed no options, a `FormData` instance is returned (and is piped to request).\n* `auth` - A hash containing values `user` || `username`, `pass` || `password`, and `sendImmediately` (optional).  See documentation above.\n* `json` - sets `body` but to JSON representation of value and adds `Content-type: application/json` header.  Additionally, parses the response body as JSON.\n* `multipart` - (experimental) array of objects which contains their own headers and `body` attribute. Sends `multipart/related` request. See example below.\n* `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.\n* `followAllRedirects` - follow non-GET HTTP 3xx responses as redirects (default: `false`)\n* `maxRedirects` - the maximum number of redirects to follow (default: `10`)\n* `encoding` - Encoding to be used on `setEncoding` of response data. If `null`, the `body` is returned as a `Buffer`.\n* `pool` - A hash object containing the agents for these requests. If omitted, the request will use the global pool (which is set to node's default `maxSockets`)\n* `pool.maxSockets` - Integer containing the maximum amount of sockets in the pool.\n* `timeout` - Integer containing the number of milliseconds to wait for a request to respond before aborting the request\n* `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`)\n* `oauth` - Options for OAuth HMAC-SHA1 signing. See documentation above.\n* `hawk` - Options for [Hawk signing](https://github.com/hueniverse/hawk). The `credentials` key must contain the necessary signing info, [see hawk docs for details](https://github.com/hueniverse/hawk#usage-example).\n* `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.\n* `jar` - If `true` and `tough-cookie` is installed, remember cookies for future use (or define your custom cookie jar; see examples section)\n* `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)\n* `httpSignature` - Options for the [HTTP Signature Scheme](https://github.com/joyent/node-http-signature/blob/master/http_signing.md) using [Joyent's library](https://github.com/joyent/node-http-signature). The `keyId` and `key` properties must be specified. See the docs for other options.\n* `localAddress` - Local interface to bind for network connections.\n* `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.\n* `tunnel` - If `true`, then *always* use a tunneling proxy.  If\n  `false` (default), then tunneling will only be used if the\n  destination is `https`, or if a previous request in the redirect\n  chain used a tunneling proxy.\n* `proxyHeaderWhiteList` - A whitelist of headers to send to a\n  tunneling proxy.\n\n\nThe callback argument gets 3 arguments: \n\n1. An `error` when applicable (usually from [`http.ClientRequest`](http://nodejs.org/api/http.html#http_class_http_clientrequest) object)\n2. An [`http.IncomingMessage`](http://nodejs.org/api/http.html#http_http_incomingmessage) object\n3. The third is the `response` body (`String` or `Buffer`, or JSON object if the `json` option is supplied)\n\n## Convenience methods\n\nThere are also shorthand methods for different HTTP METHODs and some other conveniences.\n\n### request.defaults(options)\n\nThis method returns a wrapper around the normal request API that defaults to whatever options you pass in to it.\n\n**Note:** You can call `.defaults()` on the wrapper that is returned from `request.defaults` to add/override defaults that were previously defaulted. \n\nFor example:\n```javascript\n//requests using baseRequest() will set the 'x-token' header\nvar baseRequest = request.defaults({\n  headers: {x-token: 'my-token'}\n})\n\n//requests using specialRequest() will include the 'x-token' header set in\n//baseRequest and will also include the 'special' header\nvar specialRequest = baseRequest.defaults({\n  headers: {special: 'special value'}\n})\n```\n\n### request.put\n\nSame as `request()`, but defaults to `method: \"PUT\"`.\n\n```javascript\nrequest.put(url)\n```\n\n### request.patch\n\nSame as `request()`, but defaults to `method: \"PATCH\"`.\n\n```javascript\nrequest.patch(url)\n```\n\n### request.post\n\nSame as `request()`, but defaults to `method: \"POST\"`.\n\n```javascript\nrequest.post(url)\n```\n\n### request.head\n\nSame as request() but defaults to `method: \"HEAD\"`.\n\n```javascript\nrequest.head(url)\n```\n\n### request.del\n\nSame as `request()`, but defaults to `method: \"DELETE\"`.\n\n```javascript\nrequest.del(url)\n```\n\n### request.get\n\nSame as `request()` (for uniformity).\n\n```javascript\nrequest.get(url)\n```\n### request.cookie\n\nFunction that creates a new cookie.\n\n```javascript\nrequest.cookie('cookie_string_here')\n```\n### request.jar\n\nFunction that creates a new cookie jar.\n\n```javascript\nrequest.jar()\n```\n\n\n## Examples:\n\n```javascript\n  var request = require('request')\n    , rand = Math.floor(Math.random()*100000000).toString()\n    ;\n  request(\n    { method: 'PUT'\n    , uri: 'http://mikeal.iriscouch.com/testjs/' + rand\n    , multipart:\n      [ { 'content-type': 'application/json'\n        ,  body: JSON.stringify({foo: 'bar', _attachments: {'message.txt': {follows: true, length: 18, 'content_type': 'text/plain' }}})\n        }\n      , { body: 'I am an attachment' }\n      ]\n    }\n  , function (error, response, body) {\n      if(response.statusCode == 201){\n        console.log('document saved as: http://mikeal.iriscouch.com/testjs/'+ rand)\n      } else {\n        console.log('error: '+ response.statusCode)\n        console.log(body)\n      }\n    }\n  )\n```\n\nCookies are disabled by default (else, they would be used in subsequent requests). To enable cookies, set `jar` to `true` (either in `defaults` or `options`) and install `tough-cookie`.\n\n```javascript\nvar request = request.defaults({jar: true})\nrequest('http://www.google.com', function () {\n  request('http://images.google.com')\n})\n```\n\nTo use a custom cookie jar (instead of `request`’s global cookie jar), set `jar` to an instance of `request.jar()` (either in `defaults` or `options`)\n\n```javascript\nvar j = request.jar()\nvar request = request.defaults({jar:j})\nrequest('http://www.google.com', function () {\n  request('http://images.google.com')\n})\n```\n\nOR\n\n```javascript\n// `npm install --save tough-cookie` before this works\nvar j = request.jar()\nvar cookie = request.cookie('your_cookie_here')\nj.setCookie(cookie, uri);\nrequest({url: 'http://www.google.com', jar: j}, function () {\n  request('http://images.google.com')\n})\n```\n\nTo inspect your cookie jar after a request\n\n```javascript\nvar j = request.jar() \nrequest({url: 'http://www.google.com', jar: j}, function () {\n  var cookie_string = j.getCookieString(uri); // \"key1=value1; key2=value2; ...\"\n  var cookies = j.getCookies(uri); \n  // [{key: 'key1', value: 'value1', domain: \"www.google.com\", ...}, ...]\n})\n```\n\n## Debugging\n\nThere are at least three ways to debug the operation of `request`:\n\n1. Launch the node process like `NODE_DEBUG=request node script.js`\n   (`lib,request,otherlib` works too).\n\n2. Set `require('request').debug = true` at any time (this does the same thing\n   as #1).\n\n3. Use the [request-debug module](https://github.com/nylen/request-debug) to\n   view request and response headers and bodies.\n",
