Required #SWG\Info() not found - php

Question

I'm pretty new to using Swagger. Since my project is with Laravel, I use Swaggerevel to document my API. During I tried to generate as follows,
./vendor/bin/swagger app/ -o storage/docs/api-docs.json
It shows that
[INFO] Required #SWG\Info() not found
get /api/resource.json
-----------------------
1 operations documented
-----------------------
Written to /home/admin/api/gevme-api/storage/docs/api-docs.json
When I tried to access, It localhost:8000/docs, It properly show json api which I generated. But when I tried to access localhost:8000/api-docs, the same error message show again.

Answer 1

The problem is - you're missing the #SWG\Info block.
It's a block which tells swagger some most common information about your API.
I usually put this in a separate controller which is rendering swagger JSON.
Here's an example:
/**
* #SWG\Swagger(
* schemes={"http","https"},
* host="api.host.com",
* basePath="/",
* #SWG\Info(
* version="1.0.0",
* title="This is my website cool API",
* description="Api description...",
* termsOfService="",
* #SWG\Contact(
* email="contact#mysite.com"
* ),
* #SWG\License(
* name="Private License",
* url="URL to the license"
* )
* ),
* #SWG\ExternalDocumentation(
* description="Find out more about my website",
* url="http..."
* )
* )
*/
class SwaggerController extends...

If this happens to you, and you have the Swagger definition in the controller etc but still aren't seeing the comments make sure you don't have the following settings in your opcache configuration:
opcache.save_comments=1
opcache.load_comments=1
The settings above remove and not-load the docblox needed for swagger to create the documentation.

Answer 3

For Laravel 5.6 I launched
composer require darkaonline/l5-swagger:5.6
and quietly installed version 5.6.0 (which was linked to zircote/swagger-php version TWO), and I got subj error having #OA\Info block in Controller even.
When I runned
composer require darkaonline/l5-swagger:5.6.9
and increased version of zircote/swagger-php to
composer require zircote/swagger-php:3.0.2
my problem was solved
