如何在 OpenAPI 中定义 XML 对象数组？

Question

我正在使用 OpenAPI 3.0 和 SwaggerHub 设计一个 API。我的 API 有一个 GET 端点，它以 XML 格式返回一组员工：

<Employees>
  <Employee>
    <EmpId>001</EmpId>
    <Name>Steven</Name>
    <Mobile>1-541-754-3010</Mobile>
    <EmailId>steven@yourcomany.com</EmailId>
  </Employee>
  <Employee>
    <EmpId>002</EmpId>
    <Name>Mark</Name>
    <Mobile>1-551-754-3010</Mobile>
    <EmailId>mark@yourcomany.com</EmailId>
  </Employee>
</Employees>

到目前为止，这是我的 OpenAPI YAML 文件：

      xml:
        name: EmployeesInfo

问题是 SwaggerHub 中显示的 XML 响应示例与预期的响应 XML 不匹配。

如何正确定义 XML 对象数组？

Answer 1

如下更改您的架构。 EmployeesInfo 应该被定义为一个数组并且有xml.wrapped = true。还要确保每个架构都使用相应的 XML 标记名称指定 xml.name。

components:
  ...

  schemas:
    Employee:
      type: object
      ...
      xml:
        name: Employee

    EmployeesInfo:
      type: array
      items:
        $ref: '#/components/schemas/Employee'
      xml:
        name: Employees
        wrapped: true

Swagger UI 将显示如下响应示例（此示例是从响应架构自动生成的）：

<EmployeesInfo>
    <Employee>
        <EmpId>Employee id goes here</EmpId>
        <Name>Employee name goes here</Name>
        <Mobile>Employee mobile goes here</Mobile>
        <EmailId>Employee email goes here</EmailId>
    </Employee>
</EmployeesInfo>

如果您想显示自定义示例，例如一个有 2 名员工的数组，添加一个自定义响应示例：

components:
  responses:
    employeesAPI:
      description: This will return information about employees
      content:
        application/xml:
          schema:
            $ref: '#/components/schemas/EmployeesInfo'
          # Custom example of response XML
          example: |-
            <Employees>
              <Employee>
                <EmpId>001</EmpId>
                <Name>Steven</Name>
                <Mobile>1-541-754-3010</Mobile>
                <EmailId>steven@yourcomany.com</EmailId>
              </Employee>
              <Employee>
                <EmpId>002</EmpId>
                <Name>Mark</Name>
                <Mobile>1-551-754-3010</Mobile>
                <EmailId>mark@yourcomany.com</EmailId>
              </Employee>
            </Employees>
