Question

我有这个代码上传头像：

    if(request()->file("avatar_upload")) {
       $file = request()->file("avatar_upload");
        $ext = $file->guessClientExtension();
        if($ext == "jpg" || $ext == "jpeg"){
        $file->storeAs('public/avatars/' . Auth::user()->id , "avatar.jpg");
        }
        if($ext == "png"){
            $file->storeAs('public/avatars/' . Auth::user()->id , "avatar.png");
            $imageobject = imagecreatefrompng('public/avatars/' . Auth::user()->id . "/avatar.png");
            imagejpeg($imageobject, "avatar.jpg");
        }
    }

然而，函数imagecreatefrompng永远找不到上传的头像（我使用sylinks）

我试过了：

$imageobject = imagecreatefrompng('public/avatars/' . Auth::user()->id . "/avatar.png")

这给了我这个错误：

imagecreatefrompng(public/avatars/1/avatar.png): failed to open stream: No such file or directory

并尝试了这个：

 $imageobject = imagecreatefrompng('storage/avatars/' . Auth::user()->id . "/avatar.png");

哪个不给我任何错误，但什么都不做

试试这个。使用laravel核心函数获取公用文件夹的路径。还要确保要保存文件的目录必须具有设置为0777的权限。

if(request()->file("avatar_upload")) {
       $file = request()->file("avatar_upload");
        $ext = $file->guessClientExtension();
        if($ext == "jpg" || $ext == "jpeg"){
        $file->storeAs('public/avatars/' . Auth::user()->id , "avatar.jpg");
        }
        if($ext == "png"){
          $imageName = $file->getClientOriginalExtension();
          $file->move(public_path().'/avatars/'.Auth::user()->id,$imageName);

            $imageobject = imagecreatefrompng(public_path().'/avatars/'.Auth::user()->id. '/avatar.png');
            //-----------------------------------------------------------^^^^^^----here
            imagejpeg($imageobject, 'avatar.jpg',100);
            remove old image
            imagedestroy($imageobject);
        }
    }

根据你的意见，如果是sym链接，那么它应该是这样的

$imageobject = imagecreatefrompng(storage_path('app/public/avatars/' . Auth::user()->id . "/avatar.png"));
imagejpeg($imageobject, "avatar.jpg");

    if(request()->file("avatar_upload")) {
          $file = request()->file("avatar_upload");
          $ext = $file->guessClientExtension();
        if($ext == "jpg" || $ext == "jpeg" || $ext == "png"){
         $file->storeAs('public/avatars/' . Auth::user()->id , "avatar.jpg");
        }
    }

无需分离png和jpeg。您也可以简单地将avatar.jpg存储为图像本身。

将PNG转换为JPG - 需要链接到存储但它不能正常工作
