flasgger is a Python library typically used in Web Services, REST, Swagger applications. flasgger has build file available, it has a Permissive License and it has high support. However flasgger has 6 bugs and it has 2 vulnerabilities. You can install using 'pip install flasgger' or download it from GitHub, PyPI.

[PyPI] . Flasgger is a Flask extension to extract [OpenAPI-Specification] from all Flask views registered in your API. Flasgger also comes with [SwaggerUI] embedded so you can access [and visualize and interact with your API resources. Flasgger also provides validation of the incoming data, using the same specification it can validates if the data received as as a POST, PUT, PATCH is valid against the schema defined using YAML, Python dictionaries or Marshmallow Schemas. Flasgger can work with simple function views or MethodViews using docstring as specification, or using @swag_from decorator to get specification from YAML or dict and also provides SwaggerView which can use Marshmallow Schemas as specification. Flasgger is compatible with Flask-RESTful so you can use Resources and swag specifications together, take a look at [restful example.] examples/restful.py). Flasgger also supports Marshmallow APISpec as base template for specification, if you are using APISPec from Marshmallow take a look at [apispec example.] examples/apispec_example.py).

            How to tune flasgger in order to use basic authentication in sending requests
            Asked 2019-Nov-18 at 08:46

            I try to use flasgger for my simple RESTful API. The API requireds the authentication/authorization and uses the basic authentication to perform any query.

            There is really good documentation about Basic Authentication in swagger.io But how can those settings be implemented in flassger? I've tried to used template to set securityDefinitions into swaggler, but the attempt hasn't been successful yet.

            UPD. Probably the issue hasn't been resolved yet. Flasgger doesnt support basic auth #103

            x-api-key only secures some resources
            Asked 2019-Oct-29 at 16:34

            My setup:

            flask - awsLambda - zappa - api gateway

            I do have a simple app running via above mentioned services. In my zappa_settings.json I have 'api_key_required' set to true.

            Is it possible to set it up the way, that I will be using api key for every resource endpoint, but one (swagger documentation).

            If, yes, where actually do I have to set it up. I don't have any api key setup in my flask app, so I assume it has to be done somewhere in aws.console - but I cannot find it.

            EDIT: Just to add to correct answer (below). If you use flasgger it is not sufficient to add just one public endpoint pointing to /apidocs. To make documentation work without api key I had to open these enpoints:

            1. /apidocs and /apidocs/{proxy+}
            2. /apispec_1.json - may be different in your case
            3. /flasgger_static and /flasgger_static/{proxy+}


            Answered 2018-Jan-21 at 01:02

            Yes, this is possible with a bit of configuration in the AWS console.

            In your API Gateway setup you probably have the default resources created with a Zappa deployment: / and /{proxy+}.

            You can now manually create a new resource corresponding to your documentation endpoint (e.g. /docs).

            Clicking on "Actions" -> "Create Resource" you can create the new resource:

            After the resource is created, click "Actions" -> "Create Method" and choose "ANY". Point the method and resource to your Lambda function in the dialog.

            By default, the new resource should not require the API key.

            Note: you might need to redeploy the gateway before the changes take effect. "Actions" -> "Deploy API".

            How can I make Flasgger automatically validate flask-restful resource endpoints against the template_file?
            Asked 2019-Oct-10 at 11:29

            TLDR; What I'm looking to achieve:
            Since there's the option to load an universal/app-wide schema in flasgger, as defined by the template_file parameter when instantiating Swagger, how can I automatically validate all data sent to endpoints that have associated flask-restful Resource classes when using a universal json schema file?

            I'm currently designing an API and have run into a situation where when I define my entire schema from a json template file and am utilizing flask-restful Resource classes the data provided in the API calls is not validated.

            Posting to /product with a valid payload results in the expected 501 response. But, posting with an invalid payload also results in a 501 response.

            Expected Payload:



            Answered 2019-Oct-10 at 11:29

            I guess the problem is in swagger = Swagger(app, template_file='static/Swagger.json'). Could you please add the option parse and let me know the behaviour.

            File upload selector in Flasgger POST routes
            Asked 2018-Oct-09 at 12:25

            In Flasgger, I'm trying to create documentation for route which accepts uploaded files. However, despite sticking to the specification, I cannot display file selector in Flasgger UI.

            I'm using latest (as of today) flasgger==0.9.1 running OpenAPI 3 specs (as in "openapi": '3.0.0') and I saw this commit in Swagger-UI, that enables file selectors for POST file requests.

            I know similar questions were asked before, but none of them related to OAS version 3.

            My code snippet is below:



            Answered 2018-Oct-09 at 12:25

            You are mixing OpenAPI 2.0 and 3.0 syntax. In OAS3, files are described as binary strings, that is type: string and not type: file. Also, the consumes, produces and schemes keywords are not used in OAS3.

            Python flassger: Get query with extended conditions ? (more, less, between...)
            Asked 2018-Aug-21 at 15:06

            I develop a python application based on flask that connects to a postgresql database and exposes the API using flassger (swagger UI). I already defined a basic API (handle entries by ID, etc) as well a a query api to match different parameters (name=='John Doe'for example).

            I would like to expand this query api to integrate more complex queries such as lower than, higher than, between, contains, etc.

            I search on internet but couldn't find a proper way to do it. Any suggestion ?

            I found this article which was useful but does not say anything about the implementation of the query: https://hackernoon.com/restful-api-designing-guidelines-the-best-practices-60e1d954e7c9

Of course, RabbitMQ is running and I used iptables to let connections pass. For my first tests, both programs are on the same server. But if Nameko is working perfectly, I can't connect to RabbitMQ with Flask. Here are my codes...
