.ini配置文件常被用作存儲(chǔ)程序中的一些參數(shù)，通過(guò)它程序可以變得更加靈活。下面這篇文章主要給大家介紹了關(guān)于python對(duì)配置文件.ini進(jìn)行增刪改查操作的方法示例，文中通過(guò)示例代碼介紹的非常詳細(xì)，需要的朋友可以參考借鑒，下面來(lái)一起看看吧。

前言

本文主要給大家介紹的是關(guān)于python對(duì)配置文件.ini增刪改查操作的相關(guān)內(nèi)容，分享出來(lái)供大家參考學(xué)習(xí)，下面話不多說(shuō)了，來(lái)一起看看詳細(xì)的介紹：

一、先導(dǎo)入configobj庫(kù)文件

可以用pip直接安裝

#!/usr/bin/python
# -*- coding: utf-8 -*-

import json

from configobj import ConfigObj

二、增添section

這里是前后端分離的例子，從前端接收json數(shù)據(jù)，然后寫(xiě)入配置文件中

def add(self, false=None):
 self.log.debug("list")
 try:
  conf_ini = CONFIG_INI_PATH+"users.ini.bak"
  config = ConfigObj(conf_ini, encoding='UTF8')
  req = self.input["input"]
  data = req["data"]
  userName = data["userName"]
  disc = data["disc"]
  ip = data["ip"]
  expMonth = int(float(data["expDate"]) * 12)
  for user in config.items():
   if userName == user[0]:
    self.out = '{"status": 1,"msg":"用戶名已存在！"}'
    return false
   else:
    pass
  config[userName] = {}
  config[userName]['user'] = userName
  config[userName]['disc'] = disc
  config[userName]['ip'] = ip
  config[userName]['validity_date'] = data["expDate"]
  config[userName]['cert_expired'] = get_today_month(expMonth)
  config[userName]['enable'] = 0
  config[userName]['path'] = USER_KEY_PATH + userName
  config.write()
  self.out = '{"status": 0,"msg":"操作成功！"}'
 except Exception, e:
  self.out = '{"status":1, "msg":"'+str(e)+'"}'

三、修改section

def modify(self):
 self.log.debug("modify")
 try:
  conf_ini = CONFIG_INI_PATH + "users.ini.bak"
  config = ConfigObj(conf_ini, encoding='UTF8')
  req = self.input["input"]
  data = req["data"]
  userName = data["userName"]
  disc = data["disc"]
  ip = data["ip"]
  config[userName]['disc'] = disc
  config[userName]['ip'] = ip
  config.write()
  self.out = '{"status": 0,"msg":"操作成功！"}'
 except Exception, e:
  self.out = '{"status":1, "msg":"'+str(e)+'"}'

四、刪除section

通過(guò)section名找到相應(yīng)section進(jìn)行del操作

def delete(self, false=None):
 self.log.debug("delete")
 try:
  conf_ini = CONFIG_INI_PATH + "users.ini.bak"
  config = ConfigObj(conf_ini, encoding='UTF8')
  req = self.input["input"]
  data = req["data"]
  userName = data["userName"]
  for user in config.items():
   if userName == user[0]:
    del config[userName]
    config.write()
    self.out = '{"status": 0,"msg":"操作成功！"}'
    return false
   else:
    pass
  self.out = '{"status": 1,"msg":"用戶不存在！"}'
 except Exception, e:
  self.out = '{"status":1, "msg":"config err!"}'

五、查詢(xún)section

這里借用python字典將配置文件里的內(nèi)容整體輸出，代碼里還有查詢(xún)和分頁(yè)的功能

def list(self):
 self.log.debug("list")
 try:
  req = self.input["input"]
  data = req["data"]
  pageSize = req["pageSize"]
  pageIndex = req["pageIndex"]
  userName = data["userName"]
  conf_ini = CONFIG_INI_PATH + "users.ini.bak"
  config = ConfigObj(conf_ini, encoding='UTF8')
  users = []
  n = 0
  if userName == '':
   for user in config.items():
    n = n + 1
    if pageSize * pageIndex + 1 <= n <= pageSize * (pageIndex + 1):
     users.append(user[1])
    else:
     pass
  else:
   for user in config.items():
    if userName == user[0]:
     n = n + 1
     if pageSize * pageIndex + 1 <= n <= pageSize * (pageIndex + 1):
      users.append(user[1])
     else:
      pass
    else:
     pass

  utext = json.dumps(users)
  self.out = '{"status": 0,"total":'+str(n)+',"data":' + utext + '}'
 except Exception, e:
  self.out = '{"status":1, "msg":"' + str(e) + '"}'
 self.log.debug("list in.")
