大摇大摆的"Response validation failed: value expected to be an array/object but is not"

Question

我正试图让swagger project create生成的"开箱即用"helloworld项目返回xml响应，而不是json。以下是我采取的步骤：

1( 运行swagger project create并选择express选项。

2( 打开swagger.yaml并进行以下更改：

# format of the responses to the client (Accepts)
produces:
- application/xml

如果你感兴趣的话，这是整个招摇

swagger: "2.0"
info:
version: "0.0.1"
title: Hello World App
# during dev, should point to your local machine
host: localhost:10010
# basePath prefixes all resource paths 
basePath: /
# 
schemes:
# tip: remove http to make production-grade
- http
- https
# format of bodies a client can send (Content-Type)
consumes:
- application/json
# format of the responses to the client (Accepts)
produces:
- application/xml
paths:
/hello:
# binds a127 app logic to a route
x-swagger-router-controller: hello_world
get:
description: Returns 'Hello' to the caller
# used as the method name of the controller
operationId: hello
parameters:
- name: name
in: query
description: The name of the person to whom to say hello
required: false
type: string
responses:
"200":
description: Success
schema:
# a pointer to a definition
$ref: "#/definitions/HelloWorldResponse"
# responses may fall through to errors
default:
description: Error
schema:
$ref: "#/definitions/ErrorResponse"
/swagger:
x-swagger-pipe: swagger_raw
# complex objects have schema definitions
definitions:
HelloWorldResponse:
required:
- message
properties:
message:
type: string
ErrorResponse:
required:
- message
properties:
message:
type: string

3( 打开helloworld.js控制器，将res对象更改为非json，并将类型设置为application/xml。我还将jstoxml添加到项目中，以将对象转换为xml。这是代码：

'use strict';
var util = require('util');
const { toXML } = require('jstoxml');
module.exports = {
hello: hello
};
function hello(req, res) {
// variables defined in the Swagger document can be referenced using req.swagger.params.{parameter_name}
var name = req.swagger.params.name.value || 'stranger';
var hello = {message: 'hello'};
var xml = toXML(hello);
res.type('application/xml');
res.end(xml);
}

4( 运行swagger project start，然后运行以下curl请求：

curl -X GET "http://127.0.0.1:10010/hello?name=Scott" -H "accept: application/xml"

5( 收到以下回复：

{"message":"Response validation failed: value expected to be an array/object but is not","failedValidation":true,"originalResponse":"<message>hello</message>"}

服务器输出以下错误：

我做错了什么？

Answer 1

如何删除swagger.yaml:中的验证部分

definitions:
HelloWorldResponse:
required:
- message
properties:
message:
type: string

并这样写：

definitions:
HelloWorldResponse:
type: string
