NAME

JSON::Validator::OpenAPI::Mojolicious - JSON::Validator request/response adapter for Mojolicious

SYNOPSIS

  my $validator = JSON::Validator::OpenAPI::Mojolicious->new;
  $validator->load_and_validate_schema("myschema.json");
  my @errors = $validator->validate_request(
                 $c,
                 $validator->get([paths => "/wharever", "get"]),
                 $c->validation->output,
               );
  @errors = $validator->validate_response(
              $c,
              $validator->get([paths => "/wharever", "get"]),
              200,
              {some => {response => "data"}},
            );

DESCRIPTION

JSON::Validator::OpenAPI::Mojolicious is a module for validating request and response data from/to your Mojolicious application.

Do not use this module directly. Use Mojolicious::Plugin::OpenAPI instead.

STASH VARIABLES

openapi_negotiated_content_type

  $str = %c->stash("openapi_negotiated_content_type");

This value will be set when the Accept header has been validated successfully against an OpenAPI v3 schema. Note that this could have the value of "*/*" or other invalid "Content-Header" values. It will be "undef" if the "Accept" header is not accepteed.

Unfortunately, this variable is not set until you call "render" in Mojolicious::Controller, since we need a status code to figure out which types are accepted.

This means that if you want to validate the "Accept" header on input, then you have to specify that as a parameter in the spec.

ATTRIBUTES

JSON::Validator::OpenAPI::Mojolicious inherits all attributes from JSON::Validator.

formats

  $validator = $validator->formats({});
  $hash_ref = $validator->formats;

Open API support the same formats as JSON::Validator, but adds the following to the set:

byte
A padded, base64-encoded string of bytes, encoded with a URL and filename safe alphabet. Defined by RFC4648.
date
An RFC3339 date in the format YYYY-MM-DD
double
Cannot test double values with higher precision then what the "number" type already provides.
float
Will always be true if the input is a number, meaning there is no difference between "float" and "double". Patches are welcome.
int32
A signed 32 bit integer.
int64
A signed 64 bit integer. Note: This check is only available if Perl is compiled to use 64 bit integers.

version

  $str = $validator->version;

Used to get the OpenAPI Schema version to use. Will be set automatically when using "load_and_validate_schema", unless already set. Supported values are "2" an "3".

METHODS

JSON::Validator::OpenAPI::Mojolicious inherits all attributes from JSON::Validator.

load_and_validate_schema

  $validator = $validator->load_and_validate_schema($schema, \%args);

Will load and validate $schema against the OpenAPI specification. $schema can be anything "schema" in JSON::Validator accepts. The expanded specification will be stored in "schema" in JSON::Validator on success. See "schema" in JSON::Validator for the different version of $url that can be accepted.

%args can be used to further instruct the expansion and validation process:

allow_invalid_ref
Setting this to a true value, will disable the first pass. This is useful if you don't like the restrictions set by OpenAPI, regarding where you can use $ref in your specification.
version_from_class
Setting this to a module/class name will use the version number from the class and overwrite the version in the specification:
```
  {
    "info": {
      "version": "1.00" // <-- this value
    }
  }
    
```

The validation is done with a two pass process:

1.: First it will check if the $ref is only specified on the correct places. This can be disabled by setting "allow_invalid_ref" to a true value.
2.: Validate the expanded version of the spec, (without any $ref) against the OpenAPI schema.

validate_input

  @errors = $validator->validate_input($data, $schema);

This method will make sure "readOnly" is taken into account, when validating data sent to your API.

validate_request

  @errors = $validator->validate_request($c, $schema, \%input);

Takes an Mojolicious::Controller and a schema definition and returns a list of errors, if any. Validated input parameters are moved into the %input hash.

validate_response

  @errors = $validator->validate_response($c, $schema, $status, $data);
