關(guān)于 yaml -> dict 需要注意

yaml 5.1版本后棄用了yaml.load(file)這個(gè)用法，因?yàn)橛X得很不安全，5.1版本之后就修改了需要指定Loader，通過(guò)默認(rèn)加載​​器（FullLoader）禁止執(zhí)行任意函數(shù)

import yamlyamlText =’’’apiVersion: rbac.authorization.k8s.io/v1kind: ClusterRoleBindingmetadata: name: admin-userroleRef: apiGroup: rbac.authorization.k8s.io kind: ClusterRole name: cluster-adminsubjects:- kind: ServiceAccount name: admin-user namespace: kube-system’’’print(yamlText)print(type(yamlText))# yaml -> dict 沒有設(shè)置 ,Loader=yaml.FullLoader 執(zhí)行后如下含有警告dictText = yaml.load(yamlText)print(dictText)print(type(dictText))#########################apiVersion: rbac.authorization.k8s.io/v1kind: ClusterRoleBindingmetadata: name: admin-userroleRef: apiGroup: rbac.authorization.k8s.io kind: ClusterRole name: cluster-adminsubjects:- kind: ServiceAccount name: admin-user namespace: kube-system<class ’str’>/Users/yyj/Desktop/Project/HelloBike/TimeCalc/pydict2json/dict2json.py:88: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe.

1、警告提示

YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the defaultLoader is unsafe. Please read https://msg.pyyaml.org/load for full details.

2.主要原因

yaml 5.1版本后棄用了yaml.load(file)這個(gè)用法，因?yàn)橛X得很不安全，5.1版本之后就修改了需要指定Loader，通過(guò)默認(rèn)加載​​器（FullLoader）禁止執(zhí)行任意函數(shù)

3.解決方法

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

2.yaml.warnings({’YAMLLoadWarning’: False}) # 全局設(shè)置警告，不推薦

Loader的幾種加載方式

BaseLoader--僅加載最基本的YAML SafeLoader--安全地加載YAML語(yǔ)言的子集。建議用于加載不受信任的輸入。 FullLoader--加載完整的YAML語(yǔ)言。避免任意代碼執(zhí)行。這是當(dāng)前（PyYAML 5.1）默認(rèn)加載器調(diào)用yaml.load(input)（發(fā)出警告后）。 UnsafeLoader--（也稱為L(zhǎng)oader向后兼容性）原始的Loader代碼，可以通過(guò)不受信任的數(shù)據(jù)輸入輕松利用。
