Python ConfigParser 无法正确搜索 .ini 文件(Ubuntu 14、Python 3.4) [英] Python ConfigParser cannot search .ini file correctly (Ubuntu 14, Python 3.4)

问题描述

问题:代码编译得很好，但是当我调用 read_db_config 函数时，我得到异常:在 mysql_config.ini 文件中找不到 mysql"

Problem: The code compiles fine but when ever i call the read_db_config function i get "Exception: mysql not found in the mysql_config.ini file"

文件在同一目录中，但主脚本使用

The file is in the same directory but the main script runs two directories up using

import sys 
from Config.MySQL.python_mysql_dbconfig import read_db_config

我是 python 新手，到处搜索，但我似乎无法查明我的问题

I am new to python and have searched everywhere but i cannot seem to pinpoint my issue

代码:

from ConfigParser import ConfigParser

def read_db_config(filename='mysql_config.ini', section='mysql'):

    # create parser and read ini configuration file
    parser = ConfigParser()
    parser.read(filename)

    # get section, default to mysql
    db = {}
    if parser.has_section(section):
        items = parser.items(section)
        for item in items:
            db[item[0]] = item[1]
    else:
        raise Exception('{0} not found in the {1}  file'.format(section, filename))

    return db

mysql_config.ini:

mysql_config.ini:

[mysql]
database = testdba
user = root
password = test
unix_socket = /opt/lampp/var/mysql/mysql.sock

推荐答案

如果您使用 相对路径 作为文件或目录名称，python 将在您的 当前工作目录(bash中的$PWD变量).

if you use relative paths for file or directory names python will look for them (or create them) in your current working directory (the $PWD variable in bash).

如果你想让它们相对于当前的 python 文件，你可以使用 (python 3.4)

if you want to have them relative to the current python file, you can use (python 3.4)

from pathlib import Path
HERE = Path(__file__).parent.resolve()
CONFIG_PATH = HERE / '../etc/mysql_config.ini'

或(python 2.7)

or (python 2.7)

import os.path
HERE = os.path.abspath(os.path.dirname(__file__))
CONFIG_PATH = os.path.join(HERE, '../etc/mysql_config.ini')

如果您的 mysql_config.ini 文件位于 Python 脚本下的 etc 目录中.

if your mysql_config.ini file lives in the etc directory below your python script.

您当然可以始终使用绝对路径(以 / 开头；即 /home/someuser/mysql_config.ini).

you could of course always use absolute paths (starting with a /; i.e. /home/someuser/mysql_config.ini).
