We can create custom api for GraphQL.
As per the app/code/ standard, our module name is Magemonkeys/Customgraphql
We can create schema.graphqls file in module etc folder.
Below is the code for that file.
type Query
{
CustomGraphql (
username: String @doc(description: "Email of the customer")
password: String @doc(description: "Password")
fieldtype: String @doc(description: "Field Type")
): CustomGraphqlOutput @resolver(class: "Magemonkeys\Customgraphql\Model\Resolver\ResolverGraphql") @doc(description:"Customgraphql Datapassing")
}
type CustomGraphqlOutput
{
username: String
password: String
fieldtype: String
}
After that we need to create Model Resolver file.
Create file ResolverGraphql.php in this location of module
Magemonkeys/Customgraphql/Model/Resolver/
Below is the code for that file.
<?php
namespace MagemonkeysCustomgraphqlModelResolver;
use MagentoFrameworkGraphQlConfigElementField;
use MagentoFrameworkGraphQlExceptionGraphQlInputException;
use MagentoFrameworkGraphQlQueryResolverInterface;
use MagentoFrameworkGraphQlSchemaTypeResolveInfo;
use MagentoFrameworkExceptionNoSuchEntityException;
use MagentoFrameworkGraphQlExceptionGraphQlNoSuchEntityException;
class ResolverGraphql implements ResolverInterface
{
public function resolve(
Field $field,
$context,
ResolveInfo $info,
array $value = null,
array $args = null)
{
if (!isset($args['username']) || !isset($args['password']) || !isset($args['fieldtype'])||
empty($args['username']) || empty($args['password']) || empty($args['fieldtype']))
{
throw new GraphQlInputException(__('Invalid arguments list please check.'));
}
$output = [];
$output['username'] = $args['username'];
$output['password'] = $args['password'];
$output['fieldtype'] = $args['fieldtype'];
return $output ;
}
}
After that you can check API in Postman API tool.
That’s it.
