Swagger响应验证失败

Question

我正在用Swagger和NodeJS构建API，到目前为止我遇到的恼人的问题是Swagger验证了响应，而且并不总是很顺利。

我的案子：

在文件.yaml中:我使用Swagger检查了yaml语法，=>文件是正确的。

/user/createNew:
x-swagger-router-controller: xxxxxxx
post:
  tags:
  - User
  summary: Create New User
  # used as the method name of the controller
  operationId: createNewUser
  parameters:
    - name: NewUserReq
      in: body
      required: true
      description: Email register
      schema:
        $ref: "#/definitions/NewUserReq"

  responses:
    "201":
      description: Successful
      schema:
        # a pointer to a definition
        $ref: "#/definitions/CreateUserResp"
    # responses may fall through to errors
    default:
      description: Error
      schema:
        $ref: "#/definitions/ErrorResponse"


CreateUserResp:
properties:
  status:
    type: integer
    description: Response status
  response:
    $ref: "#/definitions/MsgResponse"
MsgResponse:
  required:
    - resp_msg
  properties:
    resp_msg:
     type: string

为了检查响应格式，我从Swagger生成了NodeJs文件

 examples['application/json'] = {
    "response" : {
        "resp_msg" : "aeiou"
     },
    "status" : 123
 };

在控制器文件.js中：

function createNewUser(req,res){
....

var resp = new Object();
resp.resp_msg=data.email;
final_response.status = 200;
final_response.response = resp;

console.log("createNewUser::Query succeffully", JSON.stringify(final_response)); 
//{"status":200,"response":{"resp_msg":"test@gmail.com"}}

res.set('Content-Type', 'application/json');
res.json(final_response);
}

尝试使用Postman运行API，下面的日志会出现错误：

Error: Response validation failed: failed schema validation

我不知道是什么导致了错误，我再次检查了JSON响应的结构。

非常感谢你的任何建议。

Answer 1

在尝试了一些实验之后，我成功了。我的解决方案仅仅是将yaml文件中的响应代码"201“更改为"200”，它起了作用。我不知道为什么我留下了响应代码"201“。不管怎么说，我还是新来的，我不知道这是否是一个最佳实践。我愿意接受任何更好的建议。

Answer 2

您已经将设置为required: true，这意味着您必须通过该参数，否则将出现响应验证失败的。

Answer 3

我试着复制，但它给了我一些错误。但是，我尝试删除MsgResponse并将CreateUserResp定义为单个定义，它起了作用：

CreateUserResp:
  type: object
  properties:
    response:
      type: object
      properties:
        resp_msg:
          type: string
          description: The response object
    status:
      type: number
      description: The status code

似乎您并没有将response定义为一个对象，而只是向其添加一些属性。
