我有以下JSON数据
[
{
"type": "social_media_profiles",
"data": {
"profiles": [
{
"key": "twitter",
"data": "username",
"field": "handle",
"label": "Tweet"
},
{
"key": "customLink",
"data": "abc",
"field": "url",
"label": "Click",
"color": {
"button": "red",
"text": "green",
"border": "yellow"
}
}
]
}
}
]
并遵循jsong模式
{

我想根据项color为profiles时的条件，向项key添加新属性customLink。
如果key不是customLink，则color属性不应存在。
从https://www.jsonschemavalidator.net/验证架构给出错误
Found 2 error(s)
Message: JSON does not match all schemas from 'allOf'. Invalid schema indexes: 0.
Schema path: #/items/allOf
Message: JSON does not match schema from 'then'.
Schema path: #/items/allOf/0/then/then
如何根据同级属性值有条件地附加新属性？
答案 0 :(得分：0)
在profiles.items模式中，您定义了additionalProperties: false。
additionalProperties取决于在同一架构对象中定义的properties，这意味着color将始终被禁止。
您可以将关注点分为“允许的属性”和“如果它们的值有效”。
将color对象的验证移至profiles.properties可使您在该对象级别维护additionalProperties: false。
properties对象的模式值（如果存在）仅应用于键的实例位置（因此需要使用required来要求特定键）。
简化了条件部分后，您将获得更简洁的模式。
您现在只需定义需要color的条件，而不必担心该值应该是什么样。
Sudo代码：如果key是customLink，则要求color，否则禁止color。
{
"if": {
"properties": {
"key": {
"const": "customLink"
}
}
},
"then": {
"required": [
"color"
]
},
"else": {
"not": {
"required": [
"color"
]
}
}
}
使用not，可以反转所应用子模式的验证结果，这是当您要定义不允许使用特定属性时需要执行的操作。
这里是一个现场演示，可以玩：https://jsonschema.dev/s/C9V6N
为了繁荣，这是完整的架构，其中删除了一个或两个冗余。
