Я создаю API с помощью Swagger и NodeJS, досадная проблема, с которой я столкнулся до сих пор, заключается в том, что Swagger проверяет ответ, и это не всегда гладко.
Мое дело:
В файле .yaml: я проверил синтаксис yaml с помощью Swagger Editor => File Yaml верен.
/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
Чтобы проверить формат ответа, я сгенерировал файл NodeJs из редактора Swagger.
examples['application/json'] = {
"response" : {
"resp_msg" : "aeiou"
},
"status" : 123
};
В файле контроллера .js:
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":"[email protected]"}}
res.set('Content-Type', 'application/json');
res.json(final_response);
}
Попробуйте запустить API с Postman, ошибка происходит с журналом ниже:

Я не могу понять, что вызвало ошибку, я дважды проверил структуру ответа JSON.
Очень признателен за любое предложение.
