dev-17_yaml_json-yakovlev_vs's Introduction

Домашнее задание к занятию "4.3. Языки разметки JSON и YAML" - dev-17_yaml_json-yakovlev_vs

Обязательная задача 1

Мы выгрузили JSON, который получили через API запрос к нашему сервису:

{ "info" : "Sample JSON output from our service\t",
        "elements" :[
            { "name" : "first",
            "type" : "server",
            "ip" : 7175 
            }
            { "name" : "second",
            "type" : "proxy",
            "ip : 71.78.22.43
            }
        ]
    }

Нужно найти и исправить все ошибки, которые допускает наш сервис

Решение

  • 1 строка - неэкранированный спецсимвол \t (горизонтальная табуляция)
  • 2 строка - пропущен пробел между : и [ (открытие массива)
  • 5 строка - неверная запись ip адреса?
  • 6 строка - после скобки нужна запятая
  • 9 строка - пропущены закрывающие кавычки ip" и значения

Исправленный код:

{
 "info" : "Sample JSON output from our service\\t",
  "elements" : [
    {
     "name" : "first",
     "type" : "server",
     "ip" : "71.75.22.42" 
    },
    {
     "name" : "second",
     "type" : "proxy",
     "ip" : "71.78.22.43"
    }
  ]
}

Обязательная задача 2

В прошлый рабочий день мы создавали скрипт, позволяющий опрашивать веб-сервисы и получать их IP. К уже реализованному функционалу нам нужно добавить возможность записи JSON и YAML файлов, описывающих наши сервисы. Формат записи JSON по одному сервису: { "имя сервиса" : "его IP"}. Формат записи YAML по одному сервису: - имя сервиса: его IP. Если в момент исполнения скрипта меняется IP у сервиса - он должен так же поменяться в yml и json файле.

Решение

Мой скрипт:

# !/usr/bin/env python3

import os
import json
import yaml
import time


site_list = ['drive.google.com', 'mail.google.com', 'google.com']
site_dict = {}

def check_list_of_sites(site_list, site_dict):

    for site_url in site_list:
        site_dict=check_site_dns(site_url, site_dict)
    return site_dict


def check_site_dns(site_url, site_dict):
    site_new_ip = []


    result_os = os.popen(f'dig +short {site_url} | grep  -E \'[0-9]\'')

    for result in result_os:
        # For any ip delete \n
        site_new_ip.append(result.replace("\n",""))

    print('site_new_ip: ', site_new_ip)

    if site_dict.get(site_url) != None:

        site_old_ip = site_dict[site_url]
        i = 0
        ip_changed = False
        while i < len(site_old_ip):
            if site_old_ip[i] == site_new_ip[i]:
                print(f'{site_url} - {site_old_ip[i]}.')
            else:
                print(f'[ERROR] {site_url} IP mismatch: {site_old_ip[i]} {site_new_ip[i]}.')                
                ip_changed = True
            i = i + 1

    else:
        #If it's first execution
        site_dict[site_url] = site_new_ip
        print('site_dict==', site_dict)
        ip_changed = True

    if ip_changed == True:
        with open("servers_ip.json", "w") as fp_json:
            json.dump(site_dict, fp_json, indent=2)
        with open("servers_ip.yaml", "w") as fp_yaml:
            yaml.dump(site_dict, fp_yaml, explicit_start=True, explicit_end=True)

    return site_dict

while True:
    site_dict = check_list_of_sites(site_list, site_dict)
    print("site_dict==", site_dict)
    time.sleep(3)
