问题:“无法将图像数据写入路径” - Laravel 图像干预

无法将图像数据写入路径(Laravel)

我无法将任何内容保存到 Laravel 项目中的存储目录并收到以下错误:

在过去的三周里,我一直在试图找出为什么我无法将图像保存到Laravel中的Storage文件夹中,但没有运气。我搜索了 StackOverflow 并得出结论,这可能是由于我的 Docker 映像。如果可能的话,我很想使用我的自定义图像,但让它们正常工作。这是我的设置:

上传图片文件(Laravel)

    public function updateProfilePic(Request $request)
    {
        $request->validate([
            'upload_profile_pic' => 'required|image|mimes:jpeg,jpg,png|max:2048',
        ]);
        $id = request()->get('id');

        $file = $request->file('upload_profile_pic');
        $img = Image::make($file)
            ->resize(320, 240)
            ->save(storage_path(), $file->getClientOriginalName());

        // Upload Profil Pic (IMAGE INTERVENTION - LARAVEL)
        //Image::make($request->file('upload_profile_pic'))->fit(150, 150)->save(storage_path('avatars/'.$id.'.png'));

        session()->flash("message", "Profile picture updated successfully.");
        return redirect()->back();
    }

解答

@leo 我很抱歉我再也没有回来回答这个问题。我不记得确切的修复方法,但我相信我误用了storage_path。这是更正后的 PHP 代码:

    public function uploadPostImage(Request $request)
    {
        $request->validate([
            'upload_image' => 'required|image|mimes:jpeg,jpg,png|max:2048',
        ]);
        $id = mt_rand(100000000000, 999999999999); # TODO: This is hacky, fix down the road

        if (!is_dir(storage_path("app/public/post-images"))) {
            mkdir(storage_path("app/public/post-images"), 0775, true);
        }

        // Upload Avatar (IMAGE INTERVENTION - LARAVEL)
        Image::make($request->file("upload_image"))->save(storage_path("app/public/post-images/".$id.".png"));

        session()->flash("message", "Image uploaded successfully.");
        return redirect()->back();
    }

我使用了相同的 Docker 映像和 docker-compose 文件,这意味着它必须已通过正确使用storage_path修复。
