简体中文

PSR-15 中间件的内容验证。基于 opis/json-schema。

安装

通过 composer 安装。

composer require zfegg/content-validation

用法

Opis\JsonSchema\Validator 工厂配置。

// config.php
return [
    Opis\JsonSchema\Validator::class => [
        'resolvers' => [
            'protocolDir' => [
                // foo-schema://host/foo.create.json => schema/dir/foo.create.json
                ['foo-schema', 'host',  'schema/dir'],
            ],
            'protocol' => [
            ],
            'prefix' => [
               ['prefix1', 'path/to/dir'],
               ['prefix2', 'path/to/dir'],
            ],
            'file' => [
               ['SchemaFoo', 'path/to/file'],
               ['SchemaBar', 'path/to/file2'],
            ],
            'raw' => [
               ['{"type":"object", ...}', 'schema id 1'],
               ['{"type":"object", ...}', 'schema id 2'],
            ]
        ],
        'filters' => [
            'foo-filter' => ['filter' => 'FilterFilterName', 'types' => ['integer']],
        ],
        'filtersNS' => [
            'foo-ns' => 'FilterResolverName',
        ],
    ]
]

Mezzio

在 'config.php' 中添加 ConfigProvider。

$aggregator = new ConfigAggregator(
  [
    // ...
    \Zfegg\ContentValidation\ConfigProvider::class,
  ]
);

return $aggregator->getMergedConfig();

$app->post(
  '/api/users', 
   [
   \Zfegg\ContentValidation\ContentValidationMiddleware::class,
    function (\Psr\Http\Message\ServerRequestInterface $request) {
        $data = $request->getParsedBody(); // Get valid data.
    }
], 'api.users.create')
->setOptions(['schema' => 'path-to-json-schema.json'])
//->setOptions([  
//   // or set json-schema object. 
//  'schema' => (object) [
//        'type' => 'object',
//        'properties' => (object) [
//             'age' => (object) [
//                 'type' => 'integer'
//              ]
//        ],
//        'required' => ['age']
//   ]
// ])
;

无效请求将返回状态码 422。

curl "http://host/api/users" -d 'username=foo'

HTTP/1.1 422

{
  "status": 422,
  "detail": "Failed Validation",
  "validation_messages": {
    "age": [
      "The required properties (age) are missing"
    ]
  }
}

Slim

$app->post(
  '/api/users', 
  function (\Psr\Http\Message\ServerRequestInterface $request) {
        $data = $request->getParsedBody(); // Get valid data.
  }
)
->add(\Zfegg\ContentValidation\ContentValidationMiddleware::class)
->setArgument('schema', 'path-to-json-schema.json')
;
