pyRestful is an API to develop restful services with Tornado Web Server.
We made changes from the last version to improve it and make it more easy.
With this API allows service development rest allowing access to resources, as follows (see the demos).
The API allows develop a CRUD over the resources. In this example the resource is Customer.
GET: http://myserver.domain.com:8080/customer/{id}
GET /customer/1 HTTP/1.1
GET it is equivalent to SELECT.
POST: http://myserver.domain.com:8080/customer
POST /customer HTTP/1.1
Host: myserver.domain.com
customer_name=Rodrigo&customer_address=Santiago
POST it is equivalent to INSERT.
PUT: http://myserver.domain.com:8080/customer/{id}
PUT /customer/1 HTTP/1.1
Host: myserver.domain.com
customer_name=Rodrigo&customer_address=Santiago
PUT it is equivalent to UPDATE.
DELETE: http://myserver.domain.com:8080/customer/{id}
DELETE /customer/1 HTTP/1.1
DELETE it is equivalent to DELETE.
PyRestful implements the verbs get, post, put and delete.
You must have installed python 2.7.
Download the api from github (https://github.com/rancavil/tornado-rest/archive/master.zip).
Unzip the file tornado-rest-master.zip
$ unzip tornado-rest-master.zip
Go to the directory and install.
$ cd tornado-rest-master
$ python setup.py install
Or you can install it using.
$ pip install pyrestful
(https://pypi.python.org/pypi/pyrestful/0.3.1.alpha)
This example implements a Echo Rest Service (echo_service.py).
Write the next code and save echo_service.py file.
import tornado.ioloop
import pyrestful.rest
from pyrestful import mediatypes
from pyrestful.rest import get
class EchoService(pyrestful.rest.RestHandler):
@get(_path="/echo/{name}", _produces=mediatypes.APPLICATION_JSON)
def sayHello(self, name):
return {"Hello":name}
if __name__ == '__main__':
try:
print "Start the echo service"
app = pyrestful.rest.RestService([EchoService])
app.listen(8080)
tornado.ioloop.IOLoop.instance().start()
except KeyboardInterrupt:
print "\nStop the echo service"
Execute the service with.
$ python echo_service.py
Then in a browser write the url.
http://localhost:8080/echo/rodrigo
You should see the following output in your browser.
{"Hello": "rodrigo"}
