## Usage: Raw URL
Basic usage:
```ruby
require 'rest-client'
RestClient.get(url, headers={})
RestClient.post(url, payload, headers={})
```
In the high level helpers, only POST, PATCH, and PUT take a payload argument.
To pass a payload with other HTTP verbs or to pass more advanced options, use
`RestClient::Request.execute` instead.
More detailed examples:
```ruby
require 'rest-client'
RestClient.get 'http://example.com/resource'
RestClient.get 'http://example.com/resource', {:params => {:id => 50, 'foo' => 'bar'}}
RestClient.get 'http://example.com/resource', {params: {id: 50, 'foo' => 'bar'}}
RestClient.get 'https://user:password@example.com/private/resource', {:accept => :json}
RestClient.get 'https://user:password@example.com/private/resource', {accept: :json}
RestClient.post 'http://example.com/resource', :param1 => 'one', :nested => { :param2 => 'two' }
RestClient.post 'http://example.com/resource', {param1: 'one', nested: {param2: 'two'}}
RestClient.post "http://example.com/resource", { 'x' => 1 }.to_json, :content_type => :json, :accept => :json
RestClient.post "http://example.com/resource", {'x' => 1}.to_json, {content_type: :json, accept: :json}
RestClient.delete 'http://example.com/resource'

- for result codes between `200` and `207`, a `RestClient::Response` will be returned
- for result codes `301`, `302` or `307`, the redirection will be followed if the request is a `GET` or a `HEAD`
- for result code `303`, the redirection will be followed and the request transformed into a `GET`
- for other cases, a `RestClient::Exception` holding the Response will be raised; a specific exception class will be thrown for known error codes
- for other cases, a `RestClient::ExceptionWithResponse` holding the Response will be raised; a specific exception class will be thrown for known error codes
- call `.response` on the exception to get the server's response

### Other exceptions
While most exceptions have been collected under `RestClient::RequestFailed` aka
`RestClient::ExceptionWithResponse`, there are a few quirky exceptions that
have been kept for backwards compatibility.
RestClient will propagate up exceptions like socket errors without modification:
```ruby
>> RestClient.get 'http://localhost:12345'
Exception: Errno::ECONNREFUSED: Connection refused - connect(2) for "localhost" port 12345
```
RestClient handles a few specific error cases separately in order to give
better error messages. These will hopefully be cleaned up in a future major
release.
`RestClient::ServerBrokeConnection` is translated from `EOFError` to give a
better error message.
`RestClient::SSLCertificateNotVerified` is raised when HTTPS validation fails.
Other `OpenSSL::SSL::SSLError` errors are raised as is.
### Redirection
By default, rest-client will follow HTTP 30x redirection requests.
