Bekerja dengan JSON RPC di Symfony 4


Halo semuanya, hari ini kita akan berbicara tentang cara mencari teman Symfony 4, JSON RPC dan OpenAPI 3.


Artikel ini tidak ditujukan untuk pemula, Anda harus sudah memahami cara bekerja dengan Symfony, Depedency Injection dan hal-hal "menakutkan" lainnya.


Hari ini, mari kita lihat satu implementasi spesifik JSON RPC.


Implementasi


Ada banyak implementasi JSON RPC untuk Symfony, khususnya:



Kami akan berbicara tentang yang terakhir dalam artikel ini. Perpustakaan ini memiliki beberapa keunggulan yang menentukan pilihan saya.


Ini dikembangkan tanpa mengikat kerangka kerja apa pun ( yoanm / php-jsonrpc-server-sdk ), ada bundel untuk Symfony, ia memiliki beberapa paket tambahan yang memungkinkan Anda untuk menambahkan pemeriksaan input, dokumentasi otomatis, acara dan antarmuka untuk dapat melengkapi pekerjaan tanpa redefinisi.


Instalasi


Untuk memulai, instal symfony / skeleton.


$ composer create-project symfony/skeleton jsonrpc

Buka folder proyek.


 $ cd jsonrpc

Dan instal perpustakaan yang diperlukan.


 $ composer require yoanm/symfony-jsonrpc-http-server

Dapat disesuaikan


 // config/bundles.php return [ ... Symfony\Bundle\FrameworkBundle\FrameworkBundle::class => ['all' => true], Yoanm\SymfonyJsonRpcHttpServer\JsonRpcHttpServerBundle::class => ['all' => true], ... ]; 

 # config/routes.yaml json-rpc-endpoint: resource: '@JsonRpcHttpServerBundle/Resources/config/routing/endpoint.xml' 

 # config/packages/json_rpc.yaml json_rpc_http_server: ~

Tambahkan layanan yang akan menyimpan semua metode kami.


 // src/MappingCollector.php <?php namespace App; use Yoanm\JsonRpcServer\Domain\JsonRpcMethodAwareInterface; use Yoanm\JsonRpcServer\Domain\JsonRpcMethodInterface; class MappingCollector implements JsonRpcMethodAwareInterface { /** @var JsonRpcMethodInterface[] */ private $mappingList = []; public function addJsonRpcMethod(string $methodName, JsonRpcMethodInterface $method): void { $this->mappingList[$methodName] = $method; } /** * @return JsonRpcMethodInterface[] */ public function getMappingList() : array { return $this->mappingList; } }

Dan tambahkan layanan ke services.yaml.


 # config/services.yaml services: ... mapping_aware_service: class: App\MappingCollector tags: ['json_rpc_http_server.method_aware'] ...

Implementasi Metode


Metode RPC JSON ditambahkan sebagai layanan reguler di file services.yaml. Kami pertama-tama mengimplementasikan metode ping itu sendiri.


 // src/Method/PingMethod.php <?php namespace App\Method; use Yoanm\JsonRpcServer\Domain\JsonRpcMethodInterface; class PingMethod implements JsonRpcMethodInterface { public function apply(array $paramList = null) { return 'pong'; } }

Dan tambahkan sebagai layanan.


 # config/services.yaml services: ... App\Method\PingMethod: public: false tags: [{ method: 'ping', name: 'json_rpc_http_server.jsonrpc_method' }] ...

Kami meluncurkan server web built-in Symfony.


 $ symfony serve

Kami mencoba menelepon.


 $ curl 'http://127.0.0.1:8000/json-rpc' --data-binary '[{ "jsonrpc":"2.0","method":"ping","params":[],"id" : 1 }]' 

 [ { "jsonrpc": "2.0", "id": 1, "result": "pong" } ]

Sekarang kami menerapkan metode yang menerima parameter. Kami akan mengembalikan data input sebagai jawaban.


 // src/Method/ParamsMethod.php <?php namespace App\Method; use Yoanm\JsonRpcServer\Domain\JsonRpcMethodInterface; class ParamsMethod implements JsonRpcMethodInterface { public function apply(array $paramList = null) { return $paramList; } } 

 # config/services.yaml services: ... App\Method\ParamsMethod: public: false tags: [{ method: 'params', name: 'json_rpc_http_server.jsonrpc_method' }] ...

Mencoba menelepon.


 $ curl 'http://127.0.0.1:8000/json-rpc' --data-binary '[{ "jsonrpc":"2.0","method":"params","params":{"name":"John","age":21},"id" : 1 }]' 

 [ { "jsonrpc": "2.0", "id": 1, "result": { "name": "John", "age": 21 } } ]

Metode validasi input


Jika verifikasi otomatis data pada input metode diperlukan, maka untuk kasus ini ada paket yoanm / symfony-jsonrpc-params-validator .


 $ composer require yoanm/symfony-jsonrpc-params-validator

Hubungkan bundel.


 // config/bundles.php return [ ... Yoanm\SymfonyJsonRpcParamsValidator\JsonRpcParamsValidatorBundle::class => ['all' => true], ... ];

Metode yang perlu memverifikasi input harus mengimplementasikan antarmuka Yoanm \ JsonRpcParamsSymfonyValidator \ Domain \ MethodWithValidatedParamsInterface . Mari kita sedikit memodifikasi kelas ParamsMethod .


 // src/Method/ParamsMethod.php <?php namespace App\Method; use Symfony\Component\Validator\Constraint; use Symfony\Component\Validator\Constraints\Choice; use Symfony\Component\Validator\Constraints\Collection; use Symfony\Component\Validator\Constraints\Length; use Symfony\Component\Validator\Constraints\NotBlank; use Symfony\Component\Validator\Constraints\Optional; use Symfony\Component\Validator\Constraints\Positive; use Symfony\Component\Validator\Constraints\Required; use Yoanm\JsonRpcParamsSymfonyValidator\Domain\MethodWithValidatedParamsInterface; use Yoanm\JsonRpcServer\Domain\JsonRpcMethodInterface; class ParamsMethod implements JsonRpcMethodInterface, MethodWithValidatedParamsInterface { public function apply(array $paramList = null) { return $paramList; } public function getParamsConstraint() : Constraint { return new Collection(['fields' => [ 'name' => new Required([ new Length(['min' => 1, 'max' => 32]) ]), 'age' => new Required([ new Positive() ]), 'sex' => new Optional([ new Choice(['f', 'm']) ]), ]]); } }

Sekarang jika kami menjalankan permintaan dengan parameter kosong atau dengan kesalahan, kami akan menerima kesalahan yang sesuai sebagai respons.


 $ curl 'http://127.0.0.1:8000/json-rpc' --data-binary '[{"jsonrpc":"2.0","method":"params","params":[],"id" : 1 }]' 

 [ { "jsonrpc": "2.0", "id": 1, "error": { "code": -32602, "message": "Invalid params", "data": { "violations": [ { "path": "[name]", "message": "This field is missing.", "code": "2fa2158c-2a7f-484b-98aa-975522539ff8" }, { "path": "[age]", "message": "This field is missing.", "code": "2fa2158c-2a7f-484b-98aa-975522539ff8" } ] } } } ] 

 $ curl 'http://127.0.0.1:8000/json-rpc' --data-binary '[{"jsonrpc":"2.0","method":"params","params":{"name":"John","age":-1},"id" : 1 }]' 

 [ { "jsonrpc": "2.0", "id": 1, "error": { "code": -32602, "message": "Invalid params", "data": { "violations": [ { "path": "[age]", "message": "This value should be positive.", "code": "778b7ae0-84d3-481a-9dec-35fdb64b1d78" } ] } } } 

 $ curl 'http://127.0.0.1:8000/json-rpc' --data-binary '[{ "jsonrpc":"2.0","method":"params","params":{"name":"John","age":21,"sex":"u"},"id" : 1 }]' 

 [ { "jsonrpc": "2.0", "id": 1, "error": { "code": -32602, "message": "Invalid params", "data": { "violations": [ { "path": "[sex]", "message": "The value you selected is not a valid choice.", "code": "8e179f1b-97aa-4560-a02f-2a8b42e49df7" } ] } } } ]

Dokumentasi Otomatis


Instal paket tambahan.


 composer require yoanm/symfony-jsonrpc-http-server-doc

Kami mengonfigurasi bundel.


 // config/bundles.php return [ ... Yoanm\SymfonyJsonRpcHttpServerDoc\JsonRpcHttpServerDocBundle::class => ['all' => true], ... ]; 

 # config/routes.yaml ... json-rpc-endpoint-doc: resource: '@JsonRpcHttpServerDocBundle/Resources/config/routing/endpoint.xml' 

 # config/packages/json_rpc.yaml ... json_rpc_http_server_doc: ~

Sekarang Anda bisa mendapatkan dokumentasi dalam format JSON.


 $ curl 'http://127.0.0.1:8000/doc'

Jawabannya
 { "methods": [ { "identifier": "Params", "name": "params" }, { "identifier": "Ping", "name": "ping" } ], "errors": [ { "id": "ParseError-32700", "title": "Parse error", "type": "object", "properties": { "code": -32700 } }, { "id": "InvalidRequest-32600", "title": "Invalid request", "type": "object", "properties": { "code": -32600 } }, { "id": "MethodNotFound-32601", "title": "Method not found", "type": "object", "properties": { "code": -32601 } }, { "id": "ParamsValidationsError-32602", "title": "Params validations error", "type": "object", "properties": { "code": -32602, "data": { "type": "object", "nullable": true, "required": true, "siblings": { "violations": { "type": "array", "nullable": true, "required": false } } } } }, { "id": "InternalError-32603", "title": "Internal error", "type": "object", "properties": { "code": -32603, "data": { "type": "object", "nullable": true, "required": false, "siblings": { "previous": { "description": "Previous error message", "type": "string", "nullable": true, "required": false } } } } } ], "http": { "host": "127.0.0.1:8000" } }

Tapi bagaimana caranya? Dan di mana deskripsi parameter input? Untuk melakukan ini, letakkan bundel lain yoanm / symfony-jsonrpc-params-sf-kendala-doc .


 $ composer require yoanm/symfony-jsonrpc-params-sf-constraints-doc 

 // config/bundles.php return [ ... Yoanm\SymfonyJsonRpcParamsSfConstraintsDoc\JsonRpcParamsSfConstraintsDocBundle::class => ['all' => true], ... ];

Sekarang jika kita membuat permintaan, kita akan mendapatkan metode JSON dengan parameter.


 $ curl 'http://127.0.0.1:8000/doc'

Jawabannya
 { "methods": [ { "identifier": "Params", "name": "params", "params": { "type": "object", "nullable": false, "required": true, "siblings": { "name": { "type": "string", "nullable": true, "required": true, "minLength": 1, "maxLength": 32 }, "age": { "type": "string", "nullable": true, "required": true }, "sex": { "type": "string", "nullable": true, "required": false, "allowedValues": [ "f", "m" ] } } } }, { "identifier": "Ping", "name": "ping" } ], "errors": [ { "id": "ParseError-32700", "title": "Parse error", "type": "object", "properties": { "code": -32700 } }, { "id": "InvalidRequest-32600", "title": "Invalid request", "type": "object", "properties": { "code": -32600 } }, { "id": "MethodNotFound-32601", "title": "Method not found", "type": "object", "properties": { "code": -32601 } }, { "id": "ParamsValidationsError-32602", "title": "Params validations error", "type": "object", "properties": { "code": -32602, "data": { "type": "object", "nullable": true, "required": true, "siblings": { "violations": { "type": "array", "nullable": true, "required": false, "item_validation": { "type": "object", "nullable": true, "required": true, "siblings": { "path": { "type": "string", "nullable": true, "required": true, "example": "[key]" }, "message": { "type": "string", "nullable": true, "required": true }, "code": { "type": "string", "nullable": true, "required": false } } } } } } } }, { "id": "InternalError-32603", "title": "Internal error", "type": "object", "properties": { "code": -32603, "data": { "type": "object", "nullable": true, "required": false, "siblings": { "previous": { "description": "Previous error message", "type": "string", "nullable": true, "required": false } } } } } ], "http": { "host": "127.0.0.1:8000" } }

Openapi 3


Agar dokumentasi JSON kompatibel dengan standar OpenAPI 3, Anda perlu menginstal yoanm / symfony-jsonrpc-http-server-openapi-doc .


 $ composer require yoanm/symfony-jsonrpc-http-server-openapi-doc

Dapat disesuaikan


 // config/bundles.php return [ ... Yoanm\SymfonyJsonRpcHttpServerOpenAPIDoc\JsonRpcHttpServerOpenAPIDocBundle::class => ['all' => true], ... ];

Setelah membuat permintaan baru, kami akan menerima dokumentasi JSON dalam format OpenApi 3.


 $ curl 'http://127.0.0.1:8000/doc/openapi.json'

"Previous error message", "type": "string", "nullable": true } } } } } ] } } } }

Metode Respon Dokumentasi


Tidak ada fungsional penuh waktu (misalnya, dengan mengimplementasikan antarmuka) yang memungkinkan Anda menambahkan respons metode ke dokumentasi. Tetapi ada peluang, dengan berlangganan acara, untuk menambahkan informasi yang diperlukan sendiri.


Tambahkan pendengar.


 # config/services.yaml services: ... App\Listener\MethodDocListener: tags: - name: 'kernel.event_listener' event: 'json_rpc_http_server_doc.method_doc_created' method: 'enhanceMethodDoc' - name: 'kernel.event_listener' event: 'json_rpc_http_server_openapi_doc.array_created' method: 'enhanceDoc' ... 

 // src/Listener/MethodDocListener.php <?php namespace App\Listener; use App\Domain\JsonRpcMethodWithDocInterface; use Yoanm\JsonRpcServerDoc\Domain\Model\ErrorDoc; use Yoanm\SymfonyJsonRpcHttpServerDoc\Event\MethodDocCreatedEvent; use Yoanm\SymfonyJsonRpcHttpServerOpenAPIDoc\Event\OpenAPIDocCreatedEvent; class MethodDocListener { public function enhanceMethodDoc(MethodDocCreatedEvent $event) : void { $method = $event->getMethod(); if ($method instanceof JsonRpcMethodWithDocInterface) { $doc = $event->getDoc(); $doc->setResultDoc($method->getDocResponse()); foreach ($method->getDocErrors() as $error) { if ($error instanceof ErrorDoc) { $doc->addCustomError($error); } } $doc->setDescription($method->getDocDescription()); $doc->addTag($method->getDocTag()); } } public function enhanceDoc(OpenAPIDocCreatedEvent $event) { $doc = $event->getOpenAPIDoc(); $doc['info'] = [ 'title' => 'Main title', 'version' => '1.0.0', 'description' => 'Main description' ]; $event->setOpenAPIDoc($doc); } }

Juga, agar tidak menggambarkan dokumentasi metode secara langsung di pendengar, kami akan membuat antarmuka yang harus diimplementasikan metode itu sendiri.


 // src/Domain/JsonRpcMethodWithDocInterface.php <?php namespace App\Domain; use Yoanm\JsonRpcServerDoc\Domain\Model\ErrorDoc; use Yoanm\JsonRpcServerDoc\Domain\Model\Type\TypeDoc; interface JsonRpcMethodWithDocInterface { /** * @return TypeDoc */ public function getDocResponse(): TypeDoc; /** * @return ErrorDoc[] */ public function getDocErrors(): array; /** * @return string */ public function getDocDescription(): string; /** * @return string */ public function getDocTag(): string; }

Sekarang tambahkan metode baru yang akan berisi informasi yang diperlukan.


 // src/Method/UserMethod.php <?php namespace App\Method; use App\Domain\JsonRpcMethodWithDocInterface; use Symfony\Component\Validator\Constraint; use Symfony\Component\Validator\Constraints\Choice; use Symfony\Component\Validator\Constraints\Collection; use Symfony\Component\Validator\Constraints\Length; use Symfony\Component\Validator\Constraints\NotBlank; use Symfony\Component\Validator\Constraints\Optional; use Symfony\Component\Validator\Constraints\Positive; use Symfony\Component\Validator\Constraints\Required; use Yoanm\JsonRpcParamsSymfonyValidator\Domain\MethodWithValidatedParamsInterface; use Yoanm\JsonRpcServer\Domain\JsonRpcMethodInterface; use Yoanm\JsonRpcServerDoc\Domain\Model\ErrorDoc; use Yoanm\JsonRpcServerDoc\Domain\Model\Type\ArrayDoc; use Yoanm\JsonRpcServerDoc\Domain\Model\Type\NumberDoc; use Yoanm\JsonRpcServerDoc\Domain\Model\Type\ObjectDoc; use Yoanm\JsonRpcServerDoc\Domain\Model\Type\StringDoc; use Yoanm\JsonRpcServerDoc\Domain\Model\Type\TypeDoc; class UserMethod implements JsonRpcMethodInterface, MethodWithValidatedParamsInterface, JsonRpcMethodWithDocInterface { public function apply(array $paramList = null) { return [ 'name' => $paramList['name'], 'age' => $paramList['age'], 'sex' => $paramList['sex'] ?? null, ]; } public function getParamsConstraint() : Constraint { return new Collection(['fields' => [ 'name' => new Required([ new Length(['min' => 1, 'max' => 32]) ]), 'age' => new Required([ new Positive() ]), 'sex' => new Optional([ new Choice(['f', 'm']) ]), ]]); } public function getDocDescription(): string { return 'User method'; } public function getDocTag(): string { return 'main'; } public function getDocErrors(): array { return [new ErrorDoc('Error 1', 1)]; } public function getDocResponse(): TypeDoc { $response = new ObjectDoc(); $response->setNullable(false); $response->addSibling((new StringDoc()) ->setNullable(false) ->setDescription('Name of user') ->setName('name') ); $response->addSibling((new NumberDoc()) ->setNullable(false) ->setDescription('Age of user') ->setName('age') ); $response->addSibling((new StringDoc()) ->setNullable(true) ->setDescription('Sex of user') ->setName('sex') ); return $response; } }

Jangan lupa untuk mendaftar layanan baru.


 services: ... App\Method\UserMethod: public: false tags: [{ method: 'user', name: 'json_rpc_http_server.jsonrpc_method' }] ...

Sekarang, dengan membuat permintaan baru ke /doc/openapi.json , kami mendapatkan data baru.


 curl 'http://127.0.0.1:8000/doc/openapi.json'

Jawabannya
 { "openapi": "3.0.0", "servers": [ { "url": "http:\/\/127.0.0.1:8000" } ], "paths": { ... "\/User\/..\/json-rpc": { "post": { "summary": "\"user\" json-rpc method", "description": "User method", "tags": [ "main" ], ... "responses": { "200": { "description": "JSON-RPC response", "content": { "application\/json": { "schema": { "allOf": [ ... { "type": "object", "properties": { "result": { "$ref": "#\/components\/schemas\/Method-User-Result" } } }, { "type": "object", "properties": { "error": { "oneOf": [ { "$ref": "#\/components\/schemas\/Error-Error11" }, ... ] } } } ] } } } } } } } }, "components": { "schemas": { ... "Method-User-Result": { "type": "object", "nullable": false, "properties": { "name": { "description": "Name of user", "type": "string", "nullable": false }, "age": { "description": "Age of user", "type": "number", "nullable": false }, "sex": { "description": "Sex of user", "type": "string", "nullable": true } } }, "Error-Error11": { "title": "Error 1", "allOf": [ { "type": "object", "required": [ "code", "message" ], "properties": { "code": { "type": "number" }, "message": { "type": "string" } } }, { "type": "object", "required": [ "code" ], "properties": { "code": { "example": 1 } } } ] }, ... } }, "info": { "title": "Main title", "version": "1.0.0", "description": "Main description" } }

Visualisasi dokumentasi JSON


JSON memang keren, tetapi orang biasanya ingin melihat hasil yang lebih manusiawi. File /doc/openapi.json dapat diberikan ke layanan visualisasi eksternal, seperti Swagger Editor .



Jika diinginkan, Anda dapat menginstal UI Swagger di proyek kami. Kami akan menggunakan paket harmbandstra / swagger-ui-bundle .


Untuk publikasi sumber daya yang benar, kami menambahkan yang berikut dengan composer.json.


  "scripts": { "auto-scripts": { "cache:clear": "symfony-cmd", "assets:install %PUBLIC_DIR%": "symfony-cmd" }, "post-install-cmd": [ "HarmBandstra\\SwaggerUiBundle\\Composer\\ScriptHandler::linkAssets", "@auto-scripts" ], "post-update-cmd": [ "HarmBandstra\\SwaggerUiBundle\\Composer\\ScriptHandler::linkAssets", "@auto-scripts" ] },

Setelah kami meletakkan paket.


 $ composer require harmbandstra/swagger-ui-bundle

Hubungkan bundel.


 // config/bundles.php <?php return [ // ... HarmBandstra\SwaggerUiBundle\HBSwaggerUiBundle::class => ['dev' => true] ]; 

 # config/routes.yaml _swagger-ui: resource: '@HBSwaggerUiBundle/Resources/config/routing.yml' prefix: /docs 

 # config/packages/hb_swagger_ui.yaml hb_swagger_ui: directory: "http://127.0.0.1:8000" files: - "/doc/openapi.json"

Sekarang, mengikuti tautan http://127.0.0.1:8000/docs/, kami mendapatkan dokumentasi dalam bentuk yang indah.



Ringkasan


Sebagai hasil dari semua manipulasi kami mendapat JSON RPC yang berfungsi berdasarkan Symfony 4 dan dokumentasi otomatis OpenAPI dengan visualisasi menggunakan Swagger UI.


Terima kasih semuanya.
