python 读写Plist篇（Plist）

python 读写Plist篇（Plist）

一、Plist应用环境

‌Plist文件主要在macOS和iOS开发环境中使用‌。Plist文件通常用于存储应用程序的配置信息、用户偏好设置等。在macOS和iOS开发中，Plist文件具有多种用途，包括但不限于配置文件编辑、用户偏好设置管理、本地化字符串管理和动态数据存储‌。

二、python环境（plistlib库）

‌plistlib库是第三方库‌。它是一个用于处理plist文件的Python库，常用于macOS和iOS开发中。plist文件是一种用于存储数据的文件格式，可以采用XML或二进制格式，可以存储各种类型的数据，如字典、数组、字符串、日期等‌

pip install plistlib

三、plist文件打开方式

1.在这之前，我们需要简单了解一下文件操作Tips，是用with open读写还是open读写csv文件呢/

import plistlib

# [强烈推荐使用] with opend读写：打开操作完后会自动关闭.
with open('config.plist', 'r', newline='') as rf:
	data_dict = plistlib.load(rf) # 返回字典格式
	
# open读写：只会打开，不会自动关闭，需要我们添加个close,而且open模式不能使用plistlib.dump()和plistlib.load()方法.
open('config.plist', 'r', newline='') as rf:
	data_list = rf.readlines() # 返回列表格式
	rf.close()

四、plist文件示例（config.plist）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>CBPasscodes</key>
	<dict>
		<key>0</key>
		<string>1234567890123456789012345678901234567890</string>
	</dict>
	<key>ChallengePasscodes</key>
	<dict>
		<key>Pearl</key>
		<string>445566778899</string>
	</dict>
	<key>SigningKeys</key>
	<dict>
		<key>CalData</key>
		<string>AABBCCDDEEFF</string>
	</dict>
</dict>
</plist>

五、文件读取

data_dict["ChallengePasscodes"]["Pearl"]

结果：
445566778899

六、文件写入

self.data_dict["ChallengePasscodes"]["Pearl"] = "new_param"		# 修改value
self.data_dict["ChallengePasscodes"] = {"new_key" : "new_param"}	# 存在则修改key，不存在则创建

七、文件内容删除

del self.data_dict["ChallengePasscodes"]["Pearl"]   # 删除指定key
del self.data_dict["ChallengePasscodes"]        	# 删除整段host

八、代码示例

import plistlib

class RW_Plist:
    def __init__(self, path):
        self.path = path
        with open(self.path, "rb") as rf:
            self.data_dict = plistlib.load(rf)
        with open(self.path, "rb") as rf:
            self.data_list = rf.read()

    def Get_All(self):
        print(self.data_list)
        return self.data_list 

    def Get_All_dict(self):
        print(self.data_dict)
        return self.data_dict              

    def Get_Plist(self, host=None, key=None):
        try:
            value = self.data_dict[host][key]
            print(value)
            return value
        except KeyError:
            if host not in self.data_dict:
                print("Ge Success Host is [{}], Host not defined".format(host))
                return "Get Success Host is [{}], Host not defined".format(host)
            else:
                print("Get failure Host is [{}], Key is [{}], Key not defined".format(host, key))
                return "Get failure Host is [{}], Key is [{}], Key not defined".format(host, key)
        
    def Set_Plist(self, host=None, key=None, param=None):
        try:
            try:
                self.data_dict[host][key] = param
            except:
                self.data_dict[host] = {key : param}
            with open(self.path, "wb") as wf:
                plistlib.dump(self.data_dict, wf)
            print("Set Success Host is [{}], Key is [{}], param is [{}]".format(host, key, param))
            return "Set Success Host is [{}], Key is [{}], param is [{}]".format(host, key, param)
        except Exception as e:
            print("Get failure Host is [{}], Key is [{}], param is [{}]".format(host, key, param))
            return e
    
    def Remove_Plist(self, host=None, key=None):
        try:
            if key:
                del self.data_dict[host][key]   # 删除指定元素
                print("Remove Success Host is [{}], key is [{}]".format(host, key))
            else:
                del self.data_dict[host]        # 删除整段数据
                print("Remove Success Host is [{}]".format(host))
            with open(self.path, "wb") as wf:
                plistlib.dump(self.data_dict, wf)
        except KeyError:
            if host not in self.data_dict:
                print("Remove failure Host is [{}], Host not defined".format(host))
                return "Remove failure Host is [{}], Host not defined".format(host)
            else:
                print("Remove failure Host is [{}], Key is [{}], Key not defined".format(host, key))
                return "Remove failure Host is [{}], Key is [{}], Key not defined".format(host, key)


if __name__ == "__main__":
    import os

    code_root_path = os.path.split(os.path.split(os.path.realpath(__file__))[0])[0]
    print(code_root_path)

    RW_Plist = RW_Plist(code_root_path + "/config.plist")
    RW_Plist.Get_All()
