JsonToDict

importjson

jsonData='{"a":1,"b":2,"c":3,"d":4,"e":5}';
print(jsonData)
print(type(jsonData))
text=json.loads(jsonData)
print(text)
print(type(text))


#######################
{"a":1,"b":2,"c":3,"d":4,"e":5}

{'a':1,'b':2,'c':3,'d':4,'e':5}

DictToJson

importjson
textDict={"a":1,"b":2,"c":3,"d":4,"e":5}
print(textDict)
print(type(textDict))
#字典转化为json
textJson=json.dumps(textDict)
print(textJson)
print(type(textJson))

########################

{'a':1,'b':2,'c':3,'d':4,'e':5}

{"a":1,"b":2,"c":3,"d":4,"e":5}

DictToYaml

importyaml

dictText={
"apiVersion":"rbac.authorization.k8s.io/v1",
"kind":"ClusterRoleBinding",
"metadata":{
"name":"admin-user"
},
"roleRef":{
"apiGroup":"rbac.authorization.k8s.io",
"kind":"ClusterRole",
"name":"cluster-admin"
},
"subjects":[
{
"kind":"ServiceAccount",
"name":"admin-user",
"namespace":"kube-system"
}
]
}

print(type(dictText))

yamlText=yaml.dump(dictText)
print(yamlText)
print(type(yamlText))

JsonToYaml

Json->Dict->Yaml

importjson,yaml

jsonData='{"listDict":{"a":1,"b":2,"c":3,"d":4,"e":5}}';
print(jsonData)
print(type(jsonData))
#Json->Dict
text=json.loads(jsonData)
print(text)
print(type(text))
#Dict->Yaml
textYaml=yaml.dump(text)
print(textYaml)
print(type(textYaml))

{'listDict':{'a':1,'b':2,'c':3,'d':4,'e':5}}

listDict:
a:1
b:2
c:3
d:4
e:5

Yaml->Dict

importyaml

yamlText='''
apiVersion:rbac.authorization.k8s.io/v1
kind:ClusterRoleBinding
metadata:
name:admin-user
roleRef:
apiGroup:rbac.authorization.k8s.io

print(yamlText)
print(type(yamlText))
#Yaml->Dict
dictText=yaml.load(yamlText,Loader=yaml.FullLoader)
print(dictText)
print(type(dictText))

关于yaml->dict需要注意

yaml5.1版本后弃用了yaml.load(file)这个用法，因为觉得很不安全，5.1版本之后就修改了需要指定Loader，通过默认加载器（FullLoader）禁止执行任意函数

importyaml

yamlText='''
apiVersion:rbac.authorization.k8s.io/v1
kind:ClusterRoleBinding
metadata:
name:admin-user
roleRef:
apiGroup:rbac.authorization.k8s.io
kind:ClusterRole
name:cluster-admin
subjects:
-kind:ServiceAccount
name:admin-user
namespace:kube-system'''


print(yamlText)
print(type(yamlText))
#yaml->dict没有设置,Loader=yaml.FullLoader执行后如下含有警告
dictText=yaml.load(yamlText)
print(dictText)
print(type(dictText))

1、警告提示

YAMLLoadWarning:callingyaml.load()withoutLoader=...isdeprecated,asthedefault
Loaderisunsafe.Pleasereadhttps://msg.pyyaml.org/loadforfulldetails.

2.主要原因

yaml5.1版本后弃用了yaml.load(file)这个用法，因为觉得很不安全，5.1版本之后就修改了需要指定Loader，通过默认加载器（FullLoader）禁止执行任意函数

3.解决方法

1.yaml.load(f,Loader=yaml.FullLoader)

2.yaml.warnings({'YAMLLoadWarning':False})#全局设置警告，不推荐

Loader的几种加载方式

BaseLoader--仅加载最基本的YAML
SafeLoader--安全地加载YAML语言的子集。建议用于加载不受信任的输入。
FullLoader--加载完整的YAML语言。避免任意代码执行。这是当前（PyYAML5.1）默认加载器调用yaml.load(input)（发出警告后）。
UnsafeLoader--（也称为Loader向后兼容性）原始的Loader代码，可以通过不受信任的数据输入轻松利用。
