软件定义网络基础---REST API的设计规范
二：掌握Ryu基本RESTAPI使用方法
（一）Ryu的RESTAPI
（二） REST应用样例：app/ofctl_rest.py
1.所提供的样例API接口
# REST API
#
# Retrieve the switch stats
#
# get the list of all switches
# GET /stats/switches
#
# get the desc stats of the switch
# GET /stats/desc/
#
# get flows desc stats of the switch
# GET /stats/flowdesc/
#
# get flows desc stats of the switch filtered by the fields
# POST /stats/flowdesc/
#
# get flows stats of the switch
# GET /stats/flow/
#
# get flows stats of the switch filtered by the fields
# POST /stats/flow/
#
# get aggregate flows stats of the switch
# GET /stats/aggregateflow/
#
# get aggregate flows stats of the switch filtered by the fields
# POST /stats/aggregateflow/
#
# get table stats of the switch
# GET /stats/table/
#
# get table features stats of the switch
# GET /stats/tablefeatures/
#
# get ports stats of the switch
# GET /stats/port/[/]
# Note: Specification of port number is optional
#
# get queues stats of the switch
# GET /stats/queue/[/[/]]
# Note: Specification of port number and queue id are optional
# If you want to omitting the port number and setting the queue id,
# please specify the keyword "ALL" to the port number
# e.g. GET /stats/queue/1/ALL/1
#
# get queues config stats of the switch
# GET /stats/queueconfig/[/]
# Note: Specification of port number is optional
#
# get queues desc stats of the switch
# GET /stats/queuedesc/[/[/]]
# Note: Specification of port number and queue id are optional
# If you want to omitting the port number and setting the queue id,
# please specify the keyword "ALL" to the port number
# e.g. GET /stats/queuedesc/1/ALL/1
#
# get meter features stats of the switch
# GET /stats/meterfeatures/
#
# get meter config stats of the switch
# GET /stats/meterconfig/[/]
# Note: Specification of meter id is optional
#
# get meter desc stats of the switch
# GET /stats/meterdesc/[/]
# Note: Specification of meter id is optional
#
# get meters stats of the switch
# GET /stats/meter/[/]
# Note: Specification of meter id is optional
#
# get group features stats of the switch
# GET /stats/groupfeatures/
#
# get groups desc stats of the switch
# GET /stats/groupdesc/[/]
# Note: Specification of group id is optional (OpenFlow 1.5 or later)
#
# get groups stats of the switch
# GET /stats/group/[/]
# Note: Specification of group id is optional
#
# get ports description of the switch
# GET /stats/portdesc/[/]
# Note: Specification of port number is optional (OpenFlow 1.5 or later)
# Update the switch stats
#
# add a flow entry
# POST /stats/flowentry/add
#
# modify all matching flow entries
# POST /stats/flowentry/modify
#
# modify flow entry strictly matching wildcards and priority
# POST /stats/flowentry/modify_strict
#
# delete all matching flow entries
# POST /stats/flowentry/delete
#
# delete flow entry strictly matching wildcards and priority
# POST /stats/flowentry/delete_strict
#
# delete all flow entries of the switch
# DELETE /stats/flowentry/clear/
#
# add a meter entry
# POST /stats/meterentry/add
#
# modify a meter entry
# POST /stats/meterentry/modify
#
# delete a meter entry
# POST /stats/meterentry/delete
#
# add a group entry
# POST /stats/groupentry/add
#
# modify a group entry
# POST /stats/groupentry/modify
#
# delete a group entry
# POST /stats/groupentry/delete
#
# modify behavior of the physical port
# POST /stats/portdesc/modify
#
# modify role of controller
# POST /stats/role
#
#
# send a experimeter message
# POST /stats/experimenter/
（三）Ryu官方文档：https://ryu.readthedocs.io/en/latest/app/ofctl_rest.html
三：实验开始
（一）开启Ryu控制器
ryu-manager ofctl_rest.py simple_switch_13.py --observe-links --verbose #除了使用RESTAPI之外，我们还要保证ryu控制器正常处理交换机逻辑
（二）开启Mininet
sudo mn --controller=remote --mac --topo=tree,2,2
（三）使用Curl发送URL请求
1.获取到所有交换机Get the list of all switches which connected to the controller.
$ curl -X GET http://localhost:8080/stats/switches
2.获取交换机的描述信息Get the desc stats of the switch which specified with Datapath ID in URI.
$ curl -X GET http://localhost:8080/stats/desc/1
3.其他类似
（四）Postman实验（更美观）
1.安装postman
2.获取交换机信息
