在 Lighthouse 中，resolver 所对应的类方法 __invoke 未执行的排查分析

1、GraphQL 架构定义如下

"获取主题页面的配置"
templateDetails(basename: String!): OnlineStoreThemeTemplateDetails @field(resolver: "Modules\\OnlineStoreThemeGraphQL\\Resolver\\OnlineStoreTheme\\TemplateDetailsResolver")

type OnlineStoreThemeTemplateDetails {
    sectionsData: [OnlineStoreThemeSection]
    sectionSchemas: [OnlineStoreThemeSectionSchema]
}

2、在类 TemplateDetailsResolver 中方法 __invoke 中打印输出 1，未输出。如图1

图1

public function __invoke($rootValue, array $args, GraphQLContext $context, ResolveInfo $resolveInfo)
{
	echo 1;
	exit;
}

        "templateDetails": {
          "sectionsData": null,
          "sectionSchemas": null
        },

3、GraphQL 架构定义还原如下，则对应的类方法 __invoke 能够执行到。如图2

图2

"获取主题页面的配置"
templateDetails(basename: String!): [OnlineStoreThemeSection] @field(resolver: "Modules\\OnlineStoreThemeGraphQL\\Resolver\\OnlineStoreTheme\\TemplateDetailsResolver")

type OnlineStoreThemeTemplateDetails {
    sectionsData: [OnlineStoreThemeSection]
    sectionSchemas: [OnlineStoreThemeSectionSchema]
}

4、决定拆分 GraphQL 架构定义，则对应的类方法 __invoke 能够执行到。

"获取主题页面的配置"
templateDetails(basename: String!): OnlineStoreThemeTemplateDetails

type OnlineStoreThemeTemplateDetails {
    sectionsData: [OnlineStoreThemeSection] @field(resolver: "Modules\\OnlineStoreThemeGraphQL\\Resolver\\OnlineStoreTheme\\TemplateDetailsResolver")
    sectionSchemas: [OnlineStoreThemeSectionSchema]
}

5、GraphQL 架构定义调整解析类，则对应的类方法 __invoke 能够执行到。确认问题根源在于解析类本身。

"获取主题页面的配置"
templateDetails(basename: String!): OnlineStoreThemeTemplateDetails @field(resolver: "Modules\\OnlineStoreThemeGraphQL\\Resolver\\SectionPresetsByBaseNameResolver")

type OnlineStoreThemeTemplateDetails {
    sectionsData: [OnlineStoreThemeSection]
    sectionSchemas: [OnlineStoreThemeSectionSchema]
}

6、还原至步骤 1 ，决定沿用此架构，在类的构造方法中调试程序，查看调用栈。也确认了 __construct 可以执行，但是 __invoke 未执行到。比较类(Modules\\OnlineStoreThemeGraphQL\\Resolver\\SectionPresetsByBaseNameResolver) 与 类(Modules\\OnlineStoreThemeGraphQL\\Resolver\\OnlineStoreTheme\\TemplateDetailsResolver)

7、调整类 Modules\\OnlineStoreThemeGraphQL\\Resolver\\OnlineStoreTheme\\TemplateDetailsResolver 中的方法 __invoke。删除掉 yield 的循环。方法 __invoke 能够被执行到。如图3

图3

    public function __invoke($rootValue, array $args, GraphQLContext $context, ResolveInfo $resolveInfo)
    {
        echo 44;
        exit;
        $themeId = $rootValue['templateSettingsData']['theme_id'];
        $basename = $args['basename'];
        $rawSchemaLoader = $this->themeContext
            ->getThemeViewFactory()
            ->createRawSchemaLoader();

        $rawSchemaLoaderAdapter = new RawSchemaLoaderAdapter($rawSchemaLoader);
        $sessionId = $rootValue['session_id']?? null;
        $rawSchemaLoaderAdapter->setSessionId($sessionId);

        try {
            $rawSchema = $rawSchemaLoaderAdapter->loadTemplateSchema($basename);

            $template = new Template();

            $this->templateBuilder->build($rawSchema, $template);
        } catch(\Exception $e) {
            throw new GraphQlInputException($e->getMessage());
        }

        $id = new Id([$themeId, $basename]);

    }
