Fastify 架构验证不起作用。我是否配置错误？

Question

我试图找出为什么模式验证在 Fastify 中不起作用。我有以下代码：

const postOptions = {
        schema: { 
            body: {
                type: 'object',
                properties: {
                    name: { type: 'string' },
                    parentId: { type: 'number' },
                    requiredKey: { foo: { type: 'string'} }
                }
            },
            response: {
                201: {
                    type: 'object',
                    properties: {
                        id: { type: 'number'},
                        name: { type: 'string'},
                        parentId: { type: 'number' }
                    }
                }
            }
        }
    }
    fastify.post('/sponsor', postOptions, async (request, reply) => {

        console.log(`POST /sponsor called`)

        return { id: 2, name: 'Zenotis', parentId: 1 }
    })

当我使用邮递员测试它时，我可以通过正文发送任何键和值，并且一切顺利。好像根本就没有检查过。与响应相同。我使用的是 Fastify 版本 2.11.0

编辑：这是我发送的 json 正文：

{
  "name": "Test",
  "parentId": 5555555,
  "foo": "bar"
}

这是我预计会失败的情况：

{
  "myName": "the field is not name",
  "parentID": "The D is capitalized and this is a string",
  "bar": "where did this field come from, it's not foo"
}

如果我发送这具尸体，一切都会顺利。我如何将其配置为在所有这些情况下失败？

您的架构使用需要进行一些修复：

• 如果您不设置状态代码 201，您设置的响应架构将不起作用。在对象中使用'2xx'或设置正确的代码reply
• 删除不在您需要添加的模式中的字段additionalProperties
• 如果您没有required在模式中设置字段，则所有字段都是可选的

这是一个阻塞示例：

const fastify = require('fastify')()
const postOptions = {
  schema: {
    body: {
      type: 'object',
      additionalProperties: false, // it will remove all the field that is NOT in the JSON schema
      required: [
        'name',
        'parentId',
        'requiredKey'
      ],
      properties: {
        name: { type: 'string' },
        parentId: { type: 'number' },
        requiredKey: { foo: { type: 'string' } }
      }
    },
    response: {
      201: {
        type: 'object',
        properties: {
          id: { type: 'number' },
          name: { type: 'string' },
          parentId: { type: 'number' }
        }
      }
    }
  }
}
fastify.post('/sponsor', postOptions, async (request, reply) => {
  console.log('POST /sponsor called')
  reply.code(201) // if you don't set the code 201, the response schema you set will not work
  return request.body
})

fastify.inject({
  method: 'POST',
  url: '/sponsor',
  payload: {
    name: 'Test',
    parentId: 5555555,
    foo: 'bar'
  }
}, (_, res) => {
  console.log(res.json())
    /* it will print
    {
      statusCode: 400,
      error: 'Bad Request',
      message: "body should have required property 'requiredKey'"
    }
    */

})
