New Python Packaging Proposal Aims to Solve Phantom Dependency Problem with SBOMs
PEP 770 proposes adding SBOM support to Python packages to improve transparency and catch hidden non-Python dependencies that security tools oft miss.

用一个或多个其他对象来扩展一个对象,返回被扩展的对象。
如果第一个参数设置为true,则返回一个深层次的副本,递归地复制找到的任何对象。
否则的话,副本会与原对象共享结构。 未定义的属性将不会被复制,然而从对象的原型继承的属性将会被复制。
utils.extend({},{a:1},{b:2});
//结果
{
a:1,
b:2
}
深度冻结对象
Object.freeze的深度实现
例:utils.freeze({a:1});
深度拷贝对象
Object.assign的深度实现
例:utils.copy({a:1});
获取深度path的对象值
utils.getKeyValue({id:{v:'a'},b:2},"id.v");
//'a'
utils.getKeyValue({id:{v:['a','b']},b:2},"id.v[1]");
//'b'
对深度path的对象赋值
utils.setKeyValue({id:{v:1},b:2}, 'id.v', 2);
//{id:{v:2},b:2}
utils.setKeyValue({id:{v:['a','b']},b:2}, "id.v[1]", 'c');
//{id:{v:['a','c']},b:2}
将object转换成array.
toArray(object,keyName,valueName)
例:
utils.toArray({a:1,b:1},'key','value');
//结果
[{
key:'a',
value:1
},{
key:'b',
value:1
}]
utils.toArray({a:{b:2,d:4},b:{c:2,e:5}},'id');
//结果
[{
id:'a',
b:2,
d:4
},{
id:'b',
c:2,
e:5
}]
将array转换成object.
例:
utils.toObject(['a','b','c']);
//结果
{
a:'a',
b:'b',
c:'c'
}
utils.toObject([{id:'a',b:2},{id:'b',b:2}],'id');
//结果
{
a:{
id:'a',
b:2
},
b:{
id:'b',
b:2
}
}
utils.toObject([{id:'a',b:2},{id:'b',b:2}],'id',true);
//结果
{
a:{
id:'a',
b:2,
count:0
},
b:{
id:'b',
b:2,
count:1
}
}
保存本地localStorage
获取本地localStorage,如果type=='json',这转换出json对象。
获取本地localStorage,并转换出json对象。
删除本地localStorage。
保存本地cookie,path默认为/,minSec默认无限
保存获取cookie
清除所有cookie
删除cookie
获取对应的key数组
如果数组存在这个值,则删除,如果没有,则添加
左边填充0
删除cookie,path默认为/
let a = [{ title: '选择0', key: 0 }, { title: '选择1', key: 'a1', other: '其他值' }, { title: '选择2', key: 'a2' }, { title: '选择3', key: 'a3' }];
utils.dictMapping({value: 'a1', dict: a, titleField: 'title'})
//'选择1'
utils.dictMapping({value: ['a1', 'a2'], dict: a, titleField: 'title'})
//'选择1, 选择2'
utils.dictMapping({value: 'a1|a2', dict: a, titleField: 'title', connector: '|'})
//'选择1, 选择2'
生成唯一值
获取url参数,例:aa.com?a=1
utils.getURLParam('a', window.location.search) //1
获取author, 配合umock系统
