我一直在尝试通过以下链接下载PHP的GraphQL版本:https://github.com/webonyx/graphql-php(我git被克隆,然后使用“ composer require webonyx / graphql-php”)
但是当我尝试执行“ test”文件夹中包含的代码时,我不断遇到找不到“ ...”类的错误
我首先尝试启动此示例(GraphQLTest):
<?php
declare(strict_types=1);
namespace GraphQL\Tests;
use GraphQL\Executor\Promise\Adapter\SyncPromiseAdapter;
use GraphQL\GraphQL;
use GraphQL\Type\Definition\ObjectType;
use GraphQL\Type\Definition\Type;
use GraphQL\Type\Schema;
use PHPUnit\Framework\TestCase;
use function sprintf;
class GraphQLTest extends TestCase
{
public function testPromiseToExecute() : void
{
$promiseAdapter = new SyncPromiseAdapter();
$schema = new Schema(
[
'query' => new ObjectType(
[
'name' => 'Query',
'fields' => [
'sayHi' => [
'type' => Type::nonNull(Type::string()),
'args' => [
'name' => [
'type' => Type::nonNull(Type::string()),
],
],
'resolve' => static function ($value, $args) use ($promiseAdapter) {
return $promiseAdapter->createFulfilled(sprintf('Hi %s!', $args['name']));
},
],
],
]
),
]
);
$promise = GraphQL::promiseToExecute($promiseAdapter, $schema, '{ sayHi(name: "John") }');
$result = $promiseAdapter->wait($promise);
self::assertSame(['data' => ['sayHi' => 'Hi John!']], $result->toArray());
}
}
$t = new GraphQLTest();
$t->testPromiseToExecute();
这只是测试,但我在最后添加了一行以启动该功能
但是我得到了错误:
Fatal error: Uncaught Error: Class 'PHPUnit\Framework\TestCase' not found in C:\Users\antoine\Desktop\boulot\Graphql\php\graphql-php\tests\GraphQLTest.php:15
该程序不知道PHPunit,因此我将其重新安装在父文件夹(当前文件夹)中,无济于事。
作为最后的手段,我修改了测试以将其转换为不使用phpunit的代码:
<?php
declare(strict_types=1);
namespace GraphQL\Tests;
use GraphQL\Executor\Promise\Adapter\SyncPromiseAdapter;
use GraphQL\GraphQL;
use GraphQL\Type\Definition\ObjectType;
use GraphQL\Type\Definition\Type;
use GraphQL\Type\Schema;
use function sprintf;
class GraphQLTest
{
public function testPromiseToExecute() : void
{
$promiseAdapter = new SyncPromiseAdapter();
$schema = new Schema(
[
'query' => new ObjectType(
[
'name' => 'Query',
'fields' => [
'sayHi' => [
'type' => Type::nonNull(Type::string()),
'args' => [
'name' => [
'type' => Type::nonNull(Type::string()),
],
],
'resolve' => static function ($value, $args) use ($promiseAdapter) {
return $promiseAdapter->createFulfilled(sprintf('Hi %s!', $args['name']));
},
],
],
]
),
]
);
$promise = GraphQL::promiseToExecute($promiseAdapter, $schema, '{ sayHi(name: "John") }');
$result = $promiseAdapter->wait($promise);
echo $result->toArray();
}
}
$t= new GraphQLTest();
$t->testPromiseToExecute();
但是我仍然收到错误消息:
Fatal error: Uncaught Error: Class 'GraphQL\Executor\Promise\Adapter\SyncPromiseAdapter' not found in C:\Users\antoine\Desktop\boulot\Graphql\php\graphql-php\tests\GraphQLTest.php:18
这是一个经过测试的版本,名称空间不应引起问题。我没有更改这些文件夹中的任何内容,到底怎么不识别它们?昨天(尝试失败)安装GraphQLite时,我也遇到了类似的问题。
我猜我的设置不好,从而使命名空间的行为异常,但是我不知道如何检查。
有人有什么主意吗?
