README.md on https://github.com/swagger-api/swagger-node says 'Kick the tires. Your API is live while you edit (Did we mention no code?)' -> 'Quit faking' on the next step.
So I was under impression that Swagger will generate a fake API for me.
However, if I use such swagger.yaml:
swagger: '2.0'
info:
title: test
description: test
version: "1.0.0"
host: localhost:10010
schemes:
- https
basePath: /api
produces:
- application/json
- text/event-stream
consumes:
- application/json
paths:
/pages:
get:
summary: test
description: test
responses:
200:
description: pages
schema:
type: array
items:
$ref: '#/definitions/Page'
default:
description: Unexpected error
schema:
$ref: '#/definitions/Error'
(where definitions are also given in config)
I receive 404 in both curl http://localhost:10010/api/pages and swagger editor (swagger project edit). I know about x-swagger-router-controller thing but I expected it to work out of the box. Am I doing something wrong?
I should've read the docs more carefully. Swagger gives us the mock mode (swagger project start -m)

Of course, I incessantly get this:
The request was not authenticated. Either allow unauthenticated invocations or set the proper Authorization header. Read more at https://cloud.google.com/run/docs/securing/authenticating Additional troubleshooting documentation can be found at: https://cloud.google.com/run/docs/troubleshooting#unauthorized-client
But OPTIONS might be the problem (albeit "" on GET):
"This would be really useful for us, we're using cloud run for all our microservices and want to call these from a SPA via API Gateway." "We're back to Cloud Endpoints and ESPv2 for the time being, but we 100% see the benefits of the managed API Gateway, should CORS support be available for gRPC requests."
What am I to do?
I am using Swagger 2.0.
Facing the error on UI as:
{"messages":["attribute responses.responses.bad$ref is not of type object"],"schemaValidationMessages":[{"level":"error","domain":"validation","keyword":"oneOf","message":"instance failed to match exactly one schema (matched 0 out of 2)","schema":{"loadingURI":"http://swagger.io/v2/schema.json#","pointer":"/definitions/parameter"},"instance":{"pointer":"/parameters/bad$ref"}}]}
It's a YAML based documentation with the following file referencing in the main swagger.yaml.
swagger: '2.0'
info:
$ref: ./info/index.yaml
host: example.net
basePath: /api/v1
tags:
- name: Name
description: description
schemes:
- http
- https
produces:
- application/json
consumes:
- application/json
parameters:
$ref: ./parameters/index.yaml
responses:
$ref: ./responses/index.yaml
paths:
$ref: ./paths/index.yaml
definitions:
$ref: ./definitions/index.yaml
externalDocs:
description: Find out more about Swagger
url: 'http://swagger.io'
Folder structure:
The parameters/index.yaml and responses/index.xml files are empty. This works perfectly in the Swagger Editor.
I have a collection of microservices, each with their own complete OpenAPI spec and a root level path
Microservice Definition
openapi: 3.0.0
info:
description: Microservice API
version: '0.0.1'
paths:
/:
get:
tags:
- Root
summary: Root Path
operationId: Root
responses:
'200':
description: Request was successful
deprecated: false
/healthcheck/ping:
get:
tags:
- Healthcheck
summary: Test the reachability of the microservice.
operationId: Ping
responses:
'200':
description: Request was successful
deprecated: false
And a root OpenAPI definition
openapi: "3.0.0"
info:
version: 1.0.0
title: API
servers:
- url: http://api.something.com/v1
paths:
/microservice1:
$ref: "https://storagebucket.someservice.com/service-definitions/microservice-swagger.yaml"
It's been my assumption that it's possible to arrange things this way but I'm getting a whole host of errors in the swagger editor for validity.
Using microservice-swagger.yaml#/paths/~1 gets me somewhere but I would expect that all the paths in the service yaml to simply be appended to the path in the main definition. Does anyone know how to achieve this?
(The reason behind it being to apply this root swagger to an API Gateway whilst maintaining each service as a self contained unit)
I would for example expect the resulting swagger to offer this as a path
/microservice1/healthcheck/ping
I have an API that is far from standard, and I want to create Swagger docs for it. Since it's so far from standard I won't be able to generate anything, instead I'll have to do it manually.
I followed the instructions and created the "hello-world" project, I have been trying to edit this to call my own API instead. A simple GET endpoint returning a JSON list of objects.
I am assuming I can ignore everything that has to do with controllers and mocks etc since this API already returns json data if I call it through postman. I.e its a working API and all I want Swagger for is documentation.
Unfortunately I only get an "ERROR Server not found or an error occurred" when trying it out, but if I browse to the URL it's using it works fine. So I assume there is something I am missing that Swagger needs. Keep in mind I have not change any configs or anything else in this hello-world project, only the editor.
Here is my Yaml:
swagger: "2.0"
info:
version: "0.0.1"
title: Hello World App
# during dev, should point to your local machine
host: localhost
# basePath prefixes all resource paths
basePath: /appname/api/v1/object
#

# tip: remove http to make production-grade

# format of bodies a client can send (Content-Type)
consumes:
- application/json
# format of the responses to the client (Accepts)
produces:
- application/json
paths:
/campaign/:
get:
description: Get all campaigns
# used as the method name of the controller
operationId: hello
responses:
"200":
description: Success
schema:
# a pointer to a definition
$ref: "#/definitions/HelloWorldResponse"
# responses may fall through to errors
default:

# complex objects have schema definitions
definitions:
HelloWorldResponse:
required:

properties:
message:
type: string
ErrorResponse:
required:

properties:

Here is the request it tries to send, which looks correct:
GET https://localhost/appname/api/v1/object/campaign/ HTTP/1.1
Host: localhost
Accept: application/json
Accept-Encoding: gzip,deflate,sdch

I have a following swagger file (parses fine with the Swagger online editor):
swagger: '2.0'
info:
title: Sample

basePath: /base
paths:

get:

When I run code generator on it:
java -jar swagger-codegen-cli-2.2.1.jar generate -i swagger.yaml -l java
It fails with an error:
Exception in thread "main" java.lang.NullPointerException

Am I doing something wrong in the definition of the reusable parameter?
There's a typo in your spec:
- $ref: '#parameters/reusableParam'
should be
- $ref: '#/parameters/reusableParam'
