1，关于edgex2.0

上次讲了 edgex 2.0 如何本地进行按照使用，这次开始研究具体的 API 接口了。
之前1.0 的版本的 python 脚本不管用了需要升级 API了。
两年前，edgex 还是 1.0 的时候就有人通过 python 的程序进行使用 api的方式注册设备。

但是2.0 开始这个接口都不好用了。需要升级下。：

2，使用2.0 http api 注册

第一个改变就是端口的升级。
从 48081 修改成了 59881，api 接口路径从 v1 变成 v2 了。

还有就是 profile 的定义变了，结构变了。


def createDeviceService():
    url = 'http://%s:59881/api/v2/deviceservice' % edgex_ip
    # new payload v2 body.
    payload = [{
        "apiVersion": "v2",
        "service": {
            "name": "sensor cluster control device service",
            "description": "Manage sensor clusters delivering humidity and temperature readings",

            "baseAddress": "humidity-device-service:59990"
        }
    }]
    headers = {'content-type': 'application/json'}
    response = requests.post(url, data=json.dumps(payload), headers=headers, verify=False)

    print("Result of create device service: %s with message %s" % (response, response.text))
    


def addNewDevice():
    url = 'http://%s:59881/api/v2/device' % edgex_ip

    # new payload v2 body.
    payload =     [

        }
    ]

    headers = {'content-type': 'application/json'}
    response = requests.post(url, data=json.dumps(payload), headers=headers, verify=False)
    
    print("Result of creating the device: %s with message %s" % (response, response.text))
