Python讀取敏感資料方法

1. 讀取TXT檔案

In [3]:

import json
def open_file():
    file = open("credential.txt","r")
    js = file.read()
    dic = json.loads(js)
    file.close()
    return dic
open_file()

Out[3]:

{'user': '吳披薩', 'id': '10257515', 'passwd': 'abcdefg'}

In [5]:

def open_file():
    file = open("credential.txt","r+")
    dic = eval(file.read())
    file.close()
    return dic
a = open_file()
    
    
new_json = {
    "user":a["user"],
    "id":a["id"]
}
print(new_json)
{'user': '吳披薩', 'id': '10257515'}

2. 使用 os.read() 讀取

In [9]:

import os, sys, json
# 打开文件
fd = os.open("credential.txt",os.O_RDWR)
    
# 读取文本
#ret = os.read(fd,12)
ret = os.read(fd,100)
dic = json.loads(ret)
print(dic)
# 关闭文件
os.close(fd)
{'user': '吳披薩', 'id': '10257515', 'passwd': 'abcdefg'}
