Lumen 试用 Laravel-query-builder ，文档没有 Lumen 的安装教程，我一直忘了 config 文件配置

重要的事情说三遍

Lumen 装扩展包一定要看是否有 config，需要在 bootstrap/app.php 配置

出现错误

代码

API：
localhost/orders?include=user,items
控制器：

public function index(Request $request)
{
    $orders = QueryBuilder::for(Order::class)
        ->allowedIncludes(['user', 'items.product'])
        ->paginate();

    return OrderResource::collection($orders);
}

提示

Requested include(s) `user,items` are not allowed. Allowed include(s) are `user, items, items.product`.
但是看错误提示是没有任何问题的

追踪源码

Spatie\QueryBuilder\QueryBuilderRequest.php

public function includes(): Collection
{
    $includeParameterName = config('query-builder.parameters.include');

    $includeParts = $this->query($includeParameterName);
    // 这个类继承 Illuminate\Http\Request 
    // $this->query() 应该是获取到数据的，访问 ?include=user,items 打印出来的都是数组（为何是数组详情看 $this->query() 源码，当获取不到形参时拿所有的参数作为数组）
    // 所以再试试 $includeParameterName 得到的是什么
    // $includeParameterName 为空，config('query-builder.parameters.include') 获取不到配置文件
    // 原因是 https://learnku.com/docs/lumen/6.x/configuration/6102#36c577

    if (! is_array($includeParts)) {
        $includeParts = explode(static::getIncludesArrayValueDelimiter(), $this->query($includeParameterName));
    }

    return collect($includeParts)
        ->filter()
        ->map([Str::class, 'camel']);
}

Spatie\QueryBuilder\Concerns\AddsIncludesToQuery.php

protected function ensureAllIncludesExist()
{
    // 调用 Spatie\QueryBuilder\Concerns\AddsIncludesToQuery.php 的 includes
    // 获取到的 include 参数，结果应该是 Array
    // 但是这里总是拿到一个字符串
    $includes = $this->request->includes();

    $allowedIncludeNames = $this->allowedIncludes->map(function (AllowedInclude $allowedInclude) {
        return $allowedInclude->getName();
    });

    $diff = $includes->diff($allowedIncludeNames);

    if ($diff->count()) {
        throw InvalidIncludeQuery::includesNotAllowed($diff, $allowedIncludeNames);
    }

    // TODO: Check for non-existing relationships?
}
