python3 读取配置文件 python读取config.ini文件

还在学习中。。。写的有点凌乱

感觉还是应该先学会读取配置文件才行，把一些经常需要修改的但是又经常需要用到的参数放到配置文件中方便使用（我是这么觉得的）

 

首先是config.ini的存放位置，我们把它放在根目录下（当然也可以随便想放哪放哪）

1 proDir = os.path.split(os.path.realpath(__file__))[0] //根目录地址 
2 configPath = os.path.join(proDir, "config.ini") //存放在根目录下，文件名是config.ini

config.ini的内容如下：

1 [EMAIL]
 2 mail_host = smtp.163.com
 3 mail_user = [e-mail]
 4 mail_pass = 123456
 5 mail_port = 25
 6 sender = [e-mail]
 7 receiver = [e-mail]/[e-mail]
 8 subject = Interface Test Report
 9 content = "All interface test has been complited\nplease read the report file about the detile of result in the attachment."
10 testuser = Someone
11 on_off = off
12 
13 [HTTP]
14 scheme = http
15 baseurl = www.baidu.com
16 port = 8080
17 timeout = 10.0
18 
19 [HEADERS]
20 siteuid = all
21 clientid = 100
22 token_v = 213612368807
23 token_u = 320012369021
24 
25 [DATABASE]
26 host = localhost
27 username = root
28 password = root
29 port = 3306
30 database = test

既然配置文件有了，我们就来读取配置文件吧

1 import os
 2 import codecs
 3 import configparser

 5 proDir = os.path.split(os.path.realpath(__file__))[0]
 6 configPath = os.path.join(proDir, "config.ini")

 9 class ReadConfig:
10     def __init__(self):
11         fd = open(configPath)
12         data = fd.read()
13 
14         #  remove BOM
15         if data[:3] == codecs.BOM_UTF8:
16             data = data[3:]
17             file = codecs.open(configPath, "w")
18             file.write(data)
19             file.close()
20         fd.close()
21 
22         self.cf = configparser.ConfigParser()
23         self.cf.read(configPath)
24 
25     def get_email(self, name):
26         value = self.cf.get("EMAIL", name)
27         return value
28 
29     def get_http(self, name):
30         value = self.cf.get("HTTP", name)
31         return value
32 
33     def get_headers(self, name):
34         value = self.cf.get("HEADERS", name)
35         return value
36 
37     def set_headers(self, name, value):
38         self.cf.set("HEADERS", name, value)
39         with open(configPath, 'w+') as f:
40             self.cf.write(f)
41 
42     def get_url(self, name):
43         value = self.cf.get("URL", name)
44         return value
45 
46     def get_db(self, name):
47         value = self.cf.get("DATABASE", name)
48         return value
