Download the PHP package devizzent/cebe-php-openapi without Composer

Atention

This is a fork of cebe/php-openapi. I created it as library because the pull request of the openapi3.1 was taking years and a lot of developers want to use it.

php-openapi

Read and write OpenAPI 3.x YAML and JSON files and make the content accessible in PHP objects.

It also provides a CLI tool for validating and converting OpenAPI 3.x Description files.

Supported OpenAPI versions:

• 3.0.x
• 3.1.x

Install

composer require devizzent/cebe-php-openapi

Requirements

• PHP 7.1 or higher (works fine with PHP 8)

Used by

This library provides a low level API for reading and writing OpenAPI files. It is used by higher level tools to do awesome work:

• ... (add yours)

Usage

CLI Tool

$ vendor/bin/php-openapi help
PHP OpenAPI 3 tool
------------------
by Carsten Brandt <[email protected]>

Usage:
  php-openapi <command> [<options>] [input.yml|input.json] [output.yml|output.json]

  The following commands are available:

    validate   Validate the API Description in the specified input file against the OpenAPI v3.0 schema.
               Note: the validation is performed in two steps. The results are composed of
                (1) structural errors found while reading the API Description file, and
                (2) violations of the OpenAPI v3.0 schema.

               If no input file is specified input will be read from STDIN.
               The tool will try to auto-detect the content type of the input, but may fail
               to do so. You may specify --read-yaml or --read-json to force the file type.

               Exits with code 2 on validation errors, 1 on other errors and 0 on success.

    convert    Convert a JSON or YAML input file to JSON or YAML output file.

               If no input file is specified input will be read from STDIN.
               If no output file is specified output will be written to STDOUT.
               The tool will try to auto-detect the content type of the input and output file, but may fail
               to do so. You may specify --read-yaml or --read-json to force the input file type.
               and --write-yaml or --write-json to force the output file type.

               By default all references are resolved (replaced with the object referred to). You can control
               handling of references with the following arguments:

               --resolve-none      Do not resolve references.
               --resolve-external  Only resolve references that point to external files.
                                   This process is often referred to as "inlining".
               --resolve-all       Resolve all references (default).
                                   Recursive pointers will stay references.

    inline     Convert a JSON or YAML input file to JSON or YAML output file and
               resolve all external references. The output will be a single API Description file.
               This is a shortcut for calling convert --resolve-external.

    help       Shows this usage information.

  Options:

    --read-json   force reading input as JSON. Auto-detect if not specified.
    --read-yaml   force reading input as YAML. Auto-detect if not specified.
    --write-json  force writing output as JSON. Auto-detect if not specified.
    --write-yaml  force writing output as YAML. Auto-detect if not specified.
    -s, --silent  silent mode. Will hide all success/information messages and only print errors.

Reading API Description Files

Read OpenAPI Description from JSON file:

Read OpenAPI Description from YAML:

Access API Description data:

Object properties are exactly like in the OpenAPI Specification. You may also access additional properties added by specification extensions.

Writing API Description Files

results in the following JSON data:

Writing API Description Files using prepared Objects

Since version 1.2.0, the above example can also be written like this (passing objects instead of arrays):

Reading API Description Files and Resolving References

In the above we have passed the raw JSON or YAML data to the Reader. In order to be able to resolve references to structures in external files, we must provide the full context.

If data has been loaded in a different way you can manually resolve references like this by giving a context:

Validation

The library provides simple validation operations, that check basic OpenAPI spec requirements. This is the same as "structural errors found while reading the API Description file" from the CLI tool. This validation does not include checking against the OpenAPI v3.0/v3.1 JSON schemas, this is only implemented in the CLI.

Note: Validation is done on a very basic level and is not complete. So a failing validation will show some errors, but the list of errors given may not be complete. Also a passing validation does not necessarily indicate a completely valid spec.

Development

You may use the docker environment for local development:

docker-compose build
make IN_DOCKER=1 install
make IN_DOCKER=1 test
