1. 安装yaml库
想要使用python实现yaml与json格式互相转换，需要先下载pip，再通过pip安装yaml库。
如何下载以及使用pip，可参考：pip的安装与使用，解决pip下载速度慢的问题
安装yaml库：
pip install pyyaml
2. yaml转json
新建一个test.yaml文件，添加以下内容：
A:
hello:
name: Michael
address: Beijing
B:
hello:
name: jack
address: Shanghai
代码如下：
import yaml
import json
# yaml文件内容转换成json格式
def yaml_to_json(yamlPath):
with open(yamlPath, encoding="utf-8") as f:
datas = yaml.load(f,Loader=yaml.FullLoader) # 将文件的内容转换为字典形式
jsonDatas = json.dumps(datas, indent=5) # 将字典的内容转换为json格式的字符串
print(jsonDatas)
if __name__ == "__main__":
jsonPath = 'E:/Code/Python/test/test.yaml'
yaml_to_json(jsonPath)
执行结果如下：
{
"A": {
"hello": {
"name": "Michael",
"address": "Beijing"
}
},
"B": {
"hello": {
"name": "jack",
"address": "Shanghai"
}
}
}
3. json转yaml
新建一个test.json文件，添加以下内容：
{
"A": {
"hello": {
"name": "Michael",
"address": "Beijing"
}
},
"B": {
"hello": {
"name": "jack",
"address": "Shanghai"
}
}
}代码如下：
import yaml
import json
# json文件内容转换成yaml格式
def json_to_yaml(jsonPath):
with open(jsonPath, encoding="utf-8") as f:
datas = json.load(f) # 将文件的内容转换为字典形式
yamlDatas = yaml.dump(datas, indent=5, sort_keys=False) # 将字典的内容转换为yaml格式的字符串
print(yamlDatas)
if __name__ == "__main__":
jsonPath = 'E:/Code/Python/test/test.json'
json_to_yaml(jsonPath)
执行结果如下：
A:
hello:
name: Michael
address: Beijing
B:
hello:
name: jack
address: Shanghai
注意，如果不加sort_keys=False，那么默认是排序的，则执行结果如下：
A:
hello:
address: Beijing
name: Michael
B:
hello:
address: Shanghai
name: jack
4. 批量将yaml与json文件互相转换
yaml与json文件互相转换：
import yaml
import json
import os
from pathlib import Path
from fnmatch import fnmatchcase
class Yaml_Interconversion_Json:
def __init__(self):
self.filePathList = []
# yaml文件内容转换成json格式
def yaml_to_json(self, yamlPath):
with open(yamlPath, encoding="utf-8") as f:
datas = yaml.load(f,Loader=yaml.FullLoader)
jsonDatas = json.dumps(datas, indent=5)
# print(jsonDatas)
return jsonDatas
# json文件内容转换成yaml格式
def json_to_yaml(self, jsonPath):
with open(jsonPath, encoding="utf-8") as f:
datas = json.load(f)
yamlDatas = yaml.dump(datas, indent=5)
# print(yamlDatas)
return yamlDatas
# 生成文件
def generate_file(self, filePath, datas):
if os.path.exists(filePath):
os.remove(filePath)
with open(filePath,'w') as f:
f.write(datas)
# 清空列表
def clear_list(self):
self.filePathList.clear()
# 修改文件后缀
def modify_file_suffix(self, filePath, suffix):
dirPath = os.path.dirname(filePath)
fileName = Path(filePath).stem suffix
newPath = dirPath '/' fileName
# print('{}_path：{}'.format(suffix, newPath))
return newPath
# 原yaml文件同级目录下，生成json文件
def generate_json_file(self, yamlPath, suffix ='.json'):
jsonDatas = self.yaml_to_json(yamlPath)
jsonPath = self.modify_file_suffix(yamlPath, suffix)
# print('jsonPath：{}'.format(jsonPath))
self.generate_file(jsonPath, jsonDatas)
# 原json文件同级目录下，生成yaml文件
def generate_yaml_file(self, jsonPath, suffix ='.yaml'):
yamlDatas = self.json_to_yaml(jsonPath)
yamlPath = self.modify_file_suffix(jsonPath, suffix)
# print('yamlPath：{}'.format(yamlPath))
self.generate_file(yamlPath, yamlDatas)
# 查找指定文件夹下所有相同名称的文件
def search_file(self, dirPath, fileName):
dirs = os.listdir(dirPath)
for currentFile in dirs:
absPath = dirPath '/' currentFile
if os.path.isdir(absPath):
self.search_file(absPath, fileName)
elif currentFile == fileName:
self.filePathList.append(absPath)
# 查找指定文件夹下所有相同后缀名的文件
def search_file_suffix(self, dirPath, suffix):
dirs = os.listdir(dirPath)
for currentFile in dirs:
absPath = dirPath '/' currentFile
if os.path.isdir(absPath):
if fnmatchcase(currentFile,'.*'):
pass
else:
self.search_file_suffix(absPath, suffix)
elif currentFile.split('.')[-1] == suffix:
self.filePathList.append(absPath)
# 批量删除指定文件夹下所有相同名称的文件
def batch_remove_file(self, dirPath, fileName):
self.search_file(dirPath, fileName)
print('The following files are deleted：{}'.format(self.filePathList))
for filePath in self.filePathList:
if os.path.exists(filePath):
os.remove(filePath)
self.clear_list()
# 批量删除指定文件夹下所有相同后缀名的文件
def batch_remove_file_suffix(self, dirPath, suffix):
self.search_file_suffix(dirPath, suffix)
print('The following files are deleted：{}'.format(self.filePathList))
for filePath in self.filePathList:
if os.path.exists(filePath):
os.remove(filePath)
self.clear_list()
# 批量将目录下的yaml文件转换成json文件
def batch_yaml_to_json(self, dirPath):
self.search_file_suffix(dirPath, 'yaml')
print('The converted yaml file is as follows：{}'.format(self.filePathList))
for yamPath in self.filePathList:
try:
self.generate_json_file(yamPath)
except Exception as e:
print('YAML parsing error：{}'.format(e))
self.clear_list()
# 批量将目录下的json文件转换成yaml文件
def batch_json_to_yaml(self, dirPath):
self.search_file_suffix(dirPath, 'json')
print('The converted json file is as follows：{}'.format(self.filePathList))
for jsonPath in self.filePathList:
try:
self.generate_yaml_file(jsonPath)
except Exception as e:
print('JSON parsing error：{}'.format(jsonPath))
print(e)
self.clear_list()
if __name__ == "__main__":
dirPath = 'C:/Users/hwx1109527/Desktop/yaml_to_json'
fileName = 'os_deploy_config.yaml'
suffix = 'yaml'
filePath = dirPath '/' fileName
yaml_interconversion_json = Yaml_Interconversion_Json()
yaml_interconversion_json.batch_yaml_to_json(dirPath)
# yaml_interconversion_json.batch_json_to_yaml(dirPath)
# yaml_interconversion_json.batch_remove_file_suffix(dirPath, suffix)
