Packages
The module contains the following packages:
- Build - Swagger service factory
- Controllers - Swagger UI service
Use
Install the Python package as
pip install pip-services4-swagger
Develop a RESTful service component. For example, it may look the following way.
In the register
method we load an Open API specification for the service.
You can also enable swagger by default in the constructor by setting _swagger_enable
property.
class MyRestService(RestService):
def __init__(self):
super();
self._base_route = "myservice"
self._swagger_enable = True
def __greeting(self):
name = bottle.request.query.get('name')
response = "Hello, " + name + "!"
return self.send_result(result)
def register(self):
self.register_route(
'get', '/greeting',
ObjectSchema(True)
.with_required_property("name", TypeCode.String),
self.__greeting
)
self.register_open_api_spec_from_file('./pip_services3_swagger/services/myservice.yml')
The Open API specification for the service shall be prepared either manually or using the Swagger Editor

Include Swagger service into config.yml
file and enable swagger for your REST or Commandable HTTP.
Also explicitely adding HttpEndpoint allows sharing the same port between REST services and the Swagger service.
---
...
# Shared HTTP Endpoint
- descriptor: "pip-services:endpoint:http:default:1.0"
connection:
protocol: http
host: localhost
port: 8080
# Swagger Service
- descriptor: "pip-services:swagger-service:http:default:1.0"
# My RESTful Service
- descriptor: "myservice:service:rest:default:1.0"
swagger:
enable: true
Finally, remember to add the necessary factories to your container, to allow creating the required components.
from pip_services3_rpc.build.DefaultRpcFactory import DefaultRpcFactory
from pip_services3_swagger.build.DefaultSwaggerFactory import DefaultSwaggerFactory
# ...
class MyProcess(ProccesContainer):
def __init__(self):
super(MyProcess, self).__init__("myservice", "MyService microservice")
self._factories.add(DefaultRpcFactory())
self._factories.add(DefaultSwaggerFactory())
self._factories.add(MyServiceFactory())
# ...
Launch the microservice and open the browser to open the Open API specification at http://localhost:8080/greeting/swagger
Then, open the Swagger UI using the link http://localhost:8080/swagger. The result shall look similar to the picture below.
