Lumenで「lumen Session store not set on request.」というエラーが出た時の対処
他のプロジェクトからコードをコピペしてきたらエラーに遭遇したので、対処方法をメモ。
公開日: 2018.8.22
sessionミドルウェアが読み込まれているか？
boostrap/app.phpに下記の内容が入っていればOKなはずです。
$app->extend("session",function($obj)use($app){
$app->configure("session");
$app->configure('services');
return $obj;
});
$app->alias("session",\Illuminate\Session\SessionManager::class);
$app->register(\Illuminate\Session\SessionServiceProvider::class);
$app->middleware([
\Illuminate\Session\Middleware\StartSession::class
]);
Lumenではセッションマネージャーがすでに入っているけど、有効になっていないだけなので、読み込みを指定すれば使用することができます。
session用の設定ファイルがあるか？
Laravelと違って、Lumenでは設定ファイルが初期の状態ではありません。
ルート以下に「config」ディレクトリを作成して、session.phpファイルを設定しておかないと、エラーが発生します。
session.phpはLaravelから取ってくるか、下記のコードをコピペしてみてください。（Lumen 5.6で動作確認済み）
<?php

| Session Sweeping Lottery

セッション保存用のディレクトリがあるか？
セッションの保存方法をファイルにしている場合は、storage/frameworkディレクトリ以下に「session」というディレクトリが必要です。
ディレクトリがなかったり、パーミッションが書き込みできない場合は、
(1/1) ErrorException
file_put_contents(/../../storage/framework/sessions/SqlKSzoPLPrZr20f7B7gtiq8peQ5ZjltCpiUxgUj): failed to open stream: No such file or directory
というエラーが出ます。
上記の3つ大丈夫なら、自分の環境ではエラーが消えました。
Lumenは日本語情報が少ないですが、海外のフォーラムなどには情報が比較的あるので助かりますね。
