python使用requests訪問etcd

由於本人項目中etcd的版本略低，不適用於python-etcd,etcd3這類第三方擴展包，所以呢，自己寫了用requests請求的方法，放在這里，給需要的人。

首先，etcd的請求可以使用網址的方式

get key

http://localhost:4001/key

set key

http://localhost:4001/key?value=123

廢話不多說，上代碼

class EtcdOperate:

    def __init__(self):
        """
          初始化
        """
        #基礎url
        self.basic_url = 'http://localhost:4001'

    def get_key(self, key):
        """
        獲取key內容
        :param key:
        :return:
        """
        try:
            url = '{}{}'.format(self.basic_url, key)
            response = requests.get(url)
            return response.text
        except Exception as ex:
            print("獲取key值報錯" + str(ex))
            return None

    def set_key(self, key, content):
        """
        寫入信息
        :param key:
        :param content:
        :return:
        """
        try:
            url = '{}{}'.format(self.basic_url, key)
            params = {'value':content}
            response = requests.put(url,params=params)
            return response.text
        except Exception as ex:
            print("寫入etcd'報錯" + str(ex))
            return None
