我正在尝试json使用 Python 验证有效负载jsonschema 3.0.1，大致看起来像这样（简化为麻烦的部分）：
{
"request": {
"topic": {
"param1": "bleep beep topic",
"param2": "bloop boop topic"
},
"message": {
"param1": "bleep beep message",
"param2": "bloop boop message"
}
}
}
一个有效的请求应该有两个字段：topic和 matching message。
它们中的每一个都可以param1仅由一个或两个 param1组成，并且param2。
- 有效的：
topic { param1, param2 }, body { param1, param2 } - 有效的：
topic { param1 }, body { param1 }
但它不能既没有topicwith onlyparam1也有 body with both，也不能有 a topicwith both 和 body with onlyparam2：
- 无效的：
topic { param1, param2 }, body { param1 } - 无效的：
topic { param1}, body { param1, param2 }
因为一个节点的内容取决于另一个节点的内容，所以我无法使用dependencies关键字或if-then-else构造，所以我尝试使用, 并提供一个有效子模式列表，其中包含对和版本的oneOf引用字段，如下所示：one_paramboth_params
from jsonschema import validate
one_param = {
"type": "object",
"properties": {
"param1": {
"type": "string",
}
},
"required": ["param1"]
}
both_params = {
"type": "object",
"properties": {
"param1": {
"type": "string",
},
"param2": {
"type": "string",
}
},
"required": ["param1", "param2"]
}
test_schema = {
"type": "object",
"properties": {
"request": {
"oneOf": [
{
"type": "object",
"properties": {
"topic": one_param,
"message": one_param
},
"required": ["topic", "message"]
},
{
"type": "object",
"properties": {
"topic": both_params,
"message": both_params
},
"required": ["topic", "message"]
}
],
}
}
}
验证器的行为不是我所期望的：它在两个参数的情况下都失败了，并成功地验证了一个参数或不匹配的参数的情况。
为什么我的验证模式不能像我解释的那样工作？
这是我为此目的编写的整个测试：
good_1案例验证失败good_2,bad_1并bad_2成功验证案例
