# Request -- Simplified HTTP request method
## Install
<pre>
npm install request
</pre>
Or from source:
<pre>
git clone git://github.com/mikeal/request.git
cd request
npm link
</pre>
## Super simple to use
Request is designed to be the simplest way possible to make http calls. It supports HTTPS and follows redirects by default.
```javascript
var request = require('request');
request('http://www.google.com', function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body) // Print the google web page.
}
})
```
## Streaming
You can stream any response to a file stream.
```javascript
request('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png'))
```
You 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 one is not already provided in the headers.
```javascript
fs.createReadStream('file.json').pipe(request.put('http://mysite.com/obj.json'))
```
Request can also pipe to itself. When doing so the content-type and content-length will be preserved in the PUT headers.
```javascript
request.get('http://google.com/img.png').pipe(request.put('http://mysite.com/img.png'))
```
Now let's get fancy.
```javascript
http.createServer(function (req, resp) {
if (req.url === '/doodle.png') {
if (req.method === 'PUT') {
req.pipe(request.put('http://mysite.com/doodle.png'))
} else if (req.method === 'GET' || req.method === 'HEAD') {
request.get('http://mysite.com/doodle.png').pipe(resp)
}
}
})
```
You can also pipe() from a http.ServerRequest instance and to a http.ServerResponse instance. The HTTP method and headers will be sent as well as the entity-body data. Which means that, if you don't really care about security, you can do:
```javascript
http.createServer(function (req, resp) {
if (req.url === '/doodle.png') {
var x = request('http://mysite.com/doodle.png')
req.pipe(x)
x.pipe(resp)
}
})
```
And since pipe() returns the destination stream in node 0.5.x you can do one line proxying :)
```javascript
req.pipe(request('http://mysite.com/doodle.png')).pipe(resp)
```
Also, none of this new functionality conflicts with requests previous features, it just expands them.
```javascript
var r = request.defaults({'proxy':'http://localproxy.com'})
http.createServer(function (req, resp) {
if (req.url === '/doodle.png') {
r.get('http://google.com/doodle.png').pipe(resp)
}
})
```
You can still use intermediate proxies, the requests will still follow HTTP forwards, etc.
## OAuth Signing
```javascript
// Twitter OAuth
var qs = require('querystring')
, oauth =
{ callback: 'http://mysite.com/callback/'
, consumer_key: CONSUMER_KEY
, consumer_secret: CONSUMER_SECRET
}
, url = 'https://api.twitter.com/oauth/request_token'
;
request.post({url:url, oauth:oauth}, function (e, r, body) {
// Assume by some stretch of magic you aquired the verifier
var access_token = qs.parse(body)
, oauth =
{ consumer_key: CONSUMER_KEY
, consumer_secret: CONSUMER_SECRET
, token: access_token.oauth_token
, verifier: VERIFIER
, token_secret: access_token.oauth_token_secret
}
, url = 'https://api.twitter.com/oauth/access_token'
;
request.post({url:url, oauth:oauth}, function (e, r, body) {
var perm_token = qs.parse(body)
, oauth =
{ consumer_key: CONSUMER_KEY
, consumer_secret: CONSUMER_SECRET
, token: perm_token.oauth_token
, token_secret: perm_token.oauth_token_secret
}
, url = 'https://api.twitter.com/1/users/show.json?'
, params =
{ screen_name: perm_token.screen_name
, user_id: perm_token.user_id
}
;
url += qs.stringify(params)
request.get({url:url, oauth:oauth, json:true}, function (e, r, user) {
console.log(user)
})
})
})
```
### 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()
* `qs` - object containing querystring values to be appended to the uri
* `method` - http method, defaults to GET
* `headers` - http headers, defaults to {}
* `body` - entity body for POST and PUT requests. Must be buffer or string.
* `form` - sets `body` but to querystring representation of value and adds `Content-type: application/x-www-form-urlencoded; charset=utf-8` header.
* `json` - sets `body` but to JSON representation of value and adds `Content-type: application/json` header. Additionally, parses the response body as json.
* `multipart` - (experimental) array of objects which contains their own headers and `body` attribute. Sends `multipart/related` request. See example below.
* `followRedirect` - follow HTTP 3xx responses as redirects. defaults to true.
* `followAllRedirects` - follow non-GET HTTP 3xx responses as redirects. defaults to false.
* `maxRedirects` - the maximum number of redirects to follow, defaults to 10.
* `encoding` - Encoding to be used on `setEncoding` of response data. If set to `null`, the body is returned as a Buffer.
* `pool` - A hash object containing the agents for these requests. If omitted this request will use the global pool which is set to node's default maxSockets.
* `pool.maxSockets` - Integer containing the maximum amount of sockets in the pool.
* `timeout` - Integer containing the number of milliseconds to wait for a request to respond before aborting the request
* `proxy` - An HTTP proxy to be used. Support proxy Auth with Basic Auth the same way it's supported with the `url` parameter by embedding the auth info in the uri.
* `oauth` - Options for OAuth HMAC-SHA1 signing, see documentation above.
* `strictSSL` - Set to `true` to require that 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.
* `jar` - Set to `false` if you don't want cookies to be remembered for future use or define your custom cookie jar (see examples section)
The callback argument gets 3 arguments. The first is an error when applicable (usually from the http.Client option not the http.ClientRequest object). The second in an http.ClientResponse object. The third is the response body String or Buffer.
## Convenience methods
There are also shorthand methods for different HTTP METHODs and some other conveniences.
### request.defaults(options)
This method returns a wrapper around the normal request API that defaults to whatever options you pass in to it.
### request.put
Same as request() but defaults to `method: "PUT"`.
```javascript
request.put(url)
```
### request.post
Same as request() but defaults to `method: "POST"`.
```javascript
request.post(url)
```
### request.head
Same as request() but defaults to `method: "HEAD"`.
```javascript
request.head(url)
```
### request.del
Same as request() but defaults to `method: "DELETE"`.
```javascript
request.del(url)
```
### request.get
Alias to normal request method for uniformity.
```javascript
request.get(url)
```
### request.cookie
Function that creates a new cookie.
```javascript
request.cookie('cookie_string_here')
```
### request.jar
Function that creates a new cookie jar.
```javascript
request.jar()
```
## Examples:
```javascript
var request = require('request')
, rand = Math.floor(Math.random()*100000000).toString()
;
request(
{ method: 'PUT'
, uri: 'http://mikeal.iriscouch.com/testjs/' + rand
, multipart:
[ { 'content-type': 'application/json'
, body: JSON.stringify({foo: 'bar', _attachments: {'message.txt': {follows: true, length: 18, 'content_type': 'text/plain' }}})
}
, { body: 'I am an attachment' }
