网站基于Yii PHP框架 . 当图像从网站（而不是ftp）上传到具有相同类型图像的文件夹（通常由http访问）时，此图像仅可在ftp中访问，并在http请求中导致404错误 .

文件夹和文件权限为755和644 .

换句话说，我有“bla / foo.jpg " and " bla / bla.png " which i can see by entering " http://my.url/bla/foo.jpg " and " http://my.url/bla/bla.png”或在FileZilla中使用相同的FTP地址 . 然后，我从index.html页面上传“girl.jpg”，它到达相同的/ bla文件夹 .

...我可以从FTP看到bla / girl.jpg，但不是来自“http://my.url/bla/girl.jpg” . 它具有与HTTP中看到的foo.jpg和bla.png相同的权限和相同的地址 .

文件正在从html表单上传，并在内置的Yii类的帮助下保存：

yii\web\UploadedFile;
yii\helpers\FileHelper;
yii\behaviors\TimestampBehavior;
yii\db\ActiveRecord;

public static function upload($file, $folder, $id = null, $title = null)
{
    if ($file) {
        $path = self::createFolder($folder) . '/' .
            Yii::$app->security->generateRandomString() . '.' .
            $file->extension;

        if ($file->saveAs(Yii::getAlias('@root' . $path))) {
            self::autorotateImage($file->extension, $path);

            $fileStorage = self::findOne($id);
            if ($fileStorage) {
                $fileStorage->deleteFile();
            } else {
                $fileStorage = new FileStorage();
            }
            $fileStorage->path = $path;
            $fileStorage->filename = $file->name;
            $fileStorage->title = $title;

            if ($fileStorage->validate() && $fileStorage->save()) {
                return $fileStorage->id;
            }
        }
    }

    return null;
}

这是.htaccess内容：

RewriteCond %{HTTP_HOST} ^www\.mywebsite\.com$
RewriteRule ^pages\/how\-it\-works$ "https\:\/\/mywebsite\.com\/pages\/how\-it\-works\/" [R=301,L]


RewriteEngine on
   # If a directory or a file exists, use the request directly

UPD:

尝试了Alon Eitan对这种机制的建议，但问题保持不变：

if ($fileStorage->validate() && $fileStorage->save()) {

            $oldFolder = dirname(Yii::getAlias('@root' . $path));
            $newFolder = $oldFolder . "_new";
            mkdir($newFolder, 0755);
            self::xcopy($oldFolder, $newFolder);
            self::delete_dir($oldFolder);
            rename($newFolder, $oldFolder);

            return $fileStorage->id;
        }
