资源说明：A thin, environment-agnostic helper for RESTful web service clients in JavaScript
# rest-client.js
A thin, environment-agnostic helper for RESTful web service clients in JavaScript.
This helper provides a simple API to interact with a RESTful web service, abstracting from the underlying mechanisms.
## FAQ
> Is this a fully-featured HTTP client?
No, it is not. It's rather a very thin abstraction layer to use the same code base for high-level JavaScript-based clients to RESTful web services. It is currently designed to work with PhoneGap and node.js
> Can I use it in the browser?
This helper library has not been designed for usage inside browsers (except PhoneGap) so far. Please note that PhoneGap circumvents the Same-Origin-Policy, which is not addressed in rest-client.js.
> What content types are supported?
The helper has only been designed for JSON-based APIs. While other text-based formats might be possibile as well, binary content is not supported.
## Usage
Node.js:
var restClient = require('rest-client.js');
Browser (PhoneGap!):
### API
GET request
client.get(uri, requestHeaders, function(err, responseCode, responseHeaders, responseEntity));
HEAD request
client.head(uri, requestHeaders, function(err, responseCode, responseHeaders, responseEntity));
POST request
client.post(uri, requestHeaders, requestEntity, function(err, responseCode, responseHeaders, responseEntity));
PUT request
client.put(uri, requestHeaders, requestEntity, function(err, responseCode, responseHeaders, responseEntity));
DELETE request
client.del(uri, requestHeaders, requestEntity, function(err, responseCode, responseHeaders, responseEntity));
The last argument is always a callback, executed after the response has been successfully recieved. It either contains an error object, or (code,headers,entity) of the response.
