配置文件通过读取json方式读取

{ ?"mysql":{ ???"hosts":"localhost", ???"user":"root", ???"password":"admin", ???"port":3306, ???"dbname":"jfg", ???"chart":"utf-8"}, ?"redis":{ ???"host":"localhost", ???"user":"test1", ???"password":"test123test", ???"port":"6379" ?}}

import jsonload 将文件中json的文件读取出来loads 将json的字符串转换成字典jump 将文件中的字符串写入到json的文件中jumps 将字典转换成字符串cur_path = os.path.dirname(os.path.realpath(__file__)) #当前文件夹下的路径,更加的方便。不需要将路径写死print cur_path#json中load的使用#第一种方法with open(‘c:\peizhi.json’,‘r‘) as f: ?????????db = json.load(f)#第二种方法（不写死路径）with open(cur_path + "\\" + "peizhi",‘r‘) as f: ?????????db = json.load(f)jumps的用法a ?= { ???"a" : "123", ???"b" : "456" }b = json.jumps(a)print b #打印出来的是json的值print type(b) #查看一下json的类型jumpwith open(‘‘c:\test.json","w") as d： ?????check = json.dump(a)#写入json中
