提问by TheAngelM97
I want to upload image in laravel 5.4 Here's the code:
我想在laravel 5.4中上传图片这是代码：
if ($request->hasFile('image') && $request->image->isValid()) {
$image = $request->image;
$image_name = bcrypt($image->getClientOriginalName());
Storage::disk('public')->putFileAs('images', $image, $image_name . '.' . $image->getClientOriginalExtension());
$article->image($image_name);
}
in FilesystemAdapter.php (line 146)
在 FilesystemAdapter.php（第 146 行）
I checked the FileSystemAdapter.php and saw that the problem is in this line:
我检查了 FileSystemAdapter.php，发现问题出在这一行：
$stream = fopen($file->getRealPath(), 'r+');
When I var dump the $file variable it returns the correct info, but when I var_dump($file->getRealPath();it says bool(false)and I can't upload the image
当我对 $file 变量进行 var dump 时，它返回正确的信息，但是当我var_dump($file->getRealPath();说bool(false)我无法上传图像时

my case is :
我的情况是：
the target folder did not exist there. And i create it . so error gone.
目标文件夹在那里不存在。我创造了它。所以错误消失了。
laravel admin drive is defined here:
laravel 管理驱动器在此处定义：
Config/admin.php
配置/admin.php
You can define it in public folder, for example : upload folder in public.
您可以在公共文件夹中定义它，例如：公共文件夹中的上传。
my target folder (images) should be created in /uploads/ not in public
我的目标文件夹（图像）应该在 /uploads/ 中创建，而不是在公共
So I create images in upload and errors gone
所以我在上传时创建了图像并且错误消失了

My case with Laragon 4.0.12 on Windows 10.
我在 Windows 10 上使用 Laragon 4.0.12 的情况。
The problem was that upload_tmp_dir=... in my php.ini had not set needed permissions.
问题是我的 php.ini 中的 upload_tmp_dir=... 没有设置所需的权限。
If this setting is commented the value should be the default windows temp directory (C:\Windows\Temp you can check your permissions for it).
如果此设置被注释，则该值应该是默认的 Windows 临时目录（C:\Windows\Temp，您可以检查您的权限）。
The solution - I changed it to:
解决方案 - 我将其更改为：
upload_tmp_dir = "C:\Users\{my_user}\AppData\Local\Temp"
in order to avoid messing up with changing permissions.
以免弄乱更改权限。
Restart the server after the change to take effect.
修改生效后重启服务器。
Another settings in php.ini to consider:
php.ini 中要考虑的另一个设置：
upload_max_filesize =
max_file_uploads =
Also following php extensions are needed to be enabled: exif, gd2
还需要启用以下 php 扩展：exif、gd2
