我向我的 API 网关添加了一个模型。当我发送一个正文包含字符串（而不是有效的 JSON）的 POST 请求时，模型会验证该请求。我期待它被拒绝。
我已经尝试了这两种情况来显示问题：
- 模型将验证“A_STRING”（不正确的行为）
- 模型将验证“A_STRING”{}（不正确的行为）
- 模型将失败 {"A_STRING"} （正确的行为）
我正在直接从 AWS 控制台测试 API 网关（请参阅随附的屏幕截图），以下是一个示例的日志：
Execution log for request b2b825b4-4fb2-43e6-935b-0781264eb5df
Mon Aug 17 21:45:42 UTC 2020 : Starting execution for request: b2b825b4-4fb2-43e6-935b-0781264eb5df
Mon Aug 17 21:45:42 UTC 2020 : HTTP Method: POST, Resource Path: /TrainingNotif
Mon Aug 17 21:45:42 UTC 2020 : Method request path: {}
Mon Aug 17 21:45:42 UTC 2020 : Method request query string: {}
Mon Aug 17 21:45:42 UTC 2020 : Method request headers: {}
Mon Aug 17 21:45:42 UTC 2020 : Method request body before transformations: "A_STRING"
Mon Aug 17 21:45:42 UTC 2020 : Request validation succeeded for content type application/json
如果它有帮助，这是我的模型：
{
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-04/schema#",
"required":
[
"trainingSiteRequester",
"employeeTrainingList"
],
"properties":
{
"trainingSiteRequester":
{
"type": "string"
},
"employeeTrainingList":
{
"type": "array",
"items":
{
"additionalProperties": false,
"type": "object",
"required":
[
"id",
"trainingURL",
"dueDate"
],
"properties":
{
"trainingURL":
{
"type": "string"
},
"dueDate":
{
"type": "string"
},
"id":
{
"type": "integer"
}
}
}
}
}
}
在这里要完整的是我的 CloudFormation 代码，用于将模型附加到 API Gateay：
