使用fastify-swagger指定可选的'object‘参数

Question

我有一个带有以下端点的fastify API服务。

  server.route({
    method: 'PUT',
    url: '/user/order/new',
    schema: {
      description: 'place a new order',
      body: {
        type: 'object',
        required: ['gross', 'name', 'surname', 'address', 'city', 'country', 'phone', 'email', 'cart'],
        properties: {
          gross: {
            type: 'number',
            description: 'order total'
          },
          name: {
            type: 'string',
            description: 'first name'
          },
          surname: {
            type: 'string',
            description: 'last name'
          },
          address: {
            type: 'string',
            description: 'street address'
          },
          city: {
            type: 'string',
            description: 'mailing city'
          },
          province: {
            type: 'string',
            description: 'state'
          },
          country: {
            type: 'string',
            description: 'country of residence'
          },
          phone: {
            type: 'string',
            description: 'telephone number'
          },
          email: {
            type: 'string',
            description: 'email address'
          },
          subscribe: {
            type: 'boolean',
            description: 'subscribe to newsletter'
          },
          privacy: {
            type: 'boolean',
            description: 'accepted privacy policy'
          },
          waiver: {
            type: 'boolean',
            description: 'accepted waiver'
          },
          card: {
            type: 'boolean',
            description: 'first name'
          },
          expires: {
            type: 'boolean',
            description: 'expiration date entered'
          },
          cvv: {
            type: 'boolean',
            description: 'CVV entered'
          },
          postal: {
            type: 'string',
            description: 'card billing zip'
          },
          cart: {
            type: 'array',
            description: 'shopping cart',
            items: {
              type: 'object',
              properties: {
                id: {
                  type: 'integer',
                  description: 'item id'
                },
                title: {
                  type: 'string',
                  description: 'entry title'
                },
                price: {
                  type: 'number',
                  description: 'price of a single item'
                },
                quantity: {
                  type: 'integer',
                  description: 'number of items of this kind'
                }
              }
            }
          },
          coupon: {
            type: 'string',
            description: 'discount code'
          },
          payment: {
            type: 'object',
            description: 'stripe payment object'
          }
        }
      },
      response: {
        200: {
          description: 'Successful response',
          type: 'object',
          properties: {
            id: {
              type: 'integer',
              description: 'the new order id'
            }
          }
        },
        500: {
          description: 'Internal Server Error',
          type: 'object',
          properties: {
            statusCode: { type: 'integer' },
            code: { type: 'integer' },
            error: { type: 'string' },
            message: { type: 'string' }
          }
        }
      }
    },
    handler: async (req, res) => {
      ...

我的处理程序代码运行得很好。处理程序内部的逻辑规定，如果卡标志设置为false，则处理现金支付，并且payment对象将为空。否则，付款有一堆东西返回给我的条纹。

但是，如果我使用fastify-swagger记录上面的schema，现金支付的验证就会失败-例如，当payment设置为null时。

错误如下：

"validation":[{"keyword":"type","dataPath":".payment","schemaPath":"#/properties/payment/type","params":{"type":"object"},"message":"should be object"}],"validationContext":"body"},"msg":"body.payment should be object","v":1}

我应该怎么做才能让payment接受'object‘或null？

我找到了一个可行的解决方案：

      payment: {
        type: ['object', 'null'],
        description: 'stripe payment object'
      }
