本文介绍了如何安装和使用Python的salt-api，包括通过yum安装、基本调用方式以及盐堆叠（Salt Stack）中的内置环境变量如__opts__、__salt__、__pillar__、__grains__和__context__的用途。还提到了如何获取token和自定义模块。

1.salt-api的安装

使用yum install salt-api安装api接口

2.基本调用

直接导入模块

执行结果为：

3.salt的内置环境变量：
在python的交互环境中，这些变量是不生效的，只有在自定义的模块，活着salt执行时才生效

__opts__ 配置文件，类型
__salt__ 执行modules
__salt__['cmd.run']('fdisk -l')
__salt__['network.ip_addrs']()
__pillar__ pillar
__grains__ grains

__context__
if not 'cp.fileclient' in __context__:

__context__['cp.fileclient'] = salt.fileclient.get_file_client(__opts__)

获取tokon：

4.自定义一些module

import json
import requests


class SaltServer(object):
    def __init__(self):
        self.session = requests.session()
        self.token = self.getToken()
        self.ipaddr = "http://192.168.1.55:8000"
        
    def getToken(self):
        url = "/login".format(self.ipaddr)
        headers = {"Accept": "application/json"}
        data = {
            "username": "saltapi",
            "password": "saltapi",
            "eauth": "pam"
        }
        res = self.session.post(url=url, headers=headers, data=data)
        text = res.text
        result = json.loads(text)
        token = result.get("return")[0].get("token")
        return token

    def runModules(self, minionid, fun, arg=None):
        url = self.ipaddr
        data = {
            "client": "local",
            "tgt": minionid,
            "fun": fun,
            "arg": arg
        }
        resultBean = dict()
        try:
            res = self.session.post(url=url,  data=data)
            text = res.text
            data = json.loads(text).get("return")
            resultBean['code'] = 0
            resultBean['message'] = "success"
            resultBean['data'] = data
        except Exception as e:
            resultBean['code'] = 0
            resultBean['message'] = "success"
            resultBean['data'] = e
        finally:
            return resultBean


    def runRunner(self, fun, arg=None):
        url = self.ipaddr
        data = {
            "client": "runner",
            "fun": fun,
            "arg": arg
        }
        resultBean = dict()
        try:
            res = self.session.post(url=url,  data=data)
            text = res.text
            data = json.loads(text).get("return")
            resultBean['code'] = 0
            resultBean['message'] = "success"
            resultBean['data'] = data
        except Exception as e:
            resultBean['code'] = 0
            resultBean['message'] = "success"
            resultBean['data'] = e
        finally:
            return resultBean
