GraphQL

    快速开始

    3. namespace App\Controller;
    5. use GraphQL\GraphQL;
    6. use GraphQL\Type\Schema;
    7. use Hyperf\Di\Annotation\Inject;
    8. use Hyperf\GraphQL\Annotation\Query;
    9. use Hyperf\HttpServer\Annotation\Controller;
    10. use Hyperf\HttpServer\Annotation\PostMapping;
    11. use Hyperf\HttpServer\Contract\RequestInterface;
    13. /**
    14.  * @Controller()
    15.  */
    16. class GraphQLController
    17. {
    18.     /**
    19.      * @Inject()
    20.      */
    21.     protected $schema;
    23.     /**
    24.      * @PostMapping(path="/graphql")
    25.      */
    26.     public function test(RequestInterface $request)
    27.     {
    28.         $rawInput = $request->getBody()->getContents();
    29.         $input = json_decode($rawInput, true);
    30.         $query = $input['query'];
    31.         $variableValues = isset($input['variables']) ? $input['variables'] : null;
    32.         return GraphQL::executeQuery($this->schema, $query, null, null, $variableValues)->toArray();
    33.     }
    35.     /**
    36.      * @Query()
    37.      */
    38.     public function hello(string $name): string
    39.     {
    40.         return $name;
    41.     }
    42. }

    查询:

    2.         "hello": "graphql"
    3.     }
    4. }

    类型映射

    在 GraphQLController 中加入

    1. <?php
    2. use App\Model\Product;
    4. /**
    5.  * @Query()
    6.  */
    7. public function product(string $name, float $price): Product
    8. {
    9.     return new Product($name, $price);
    10. }

    响应:

    1. {
    2.     "data": {
    3.         "hello": "graphql",
    4.         "product": {
    5.             "name": "goods",
    6.             "price": 156.5
    7.         }
    9. }
