无法打开流：文件中没有此类文件或目录，Laravel Image Upload Api

Question

我有一个api将图像存储到文件夹和db，当我尝试使用Postman测试api时，它总是返回“无法打开流：文件中没有此类文件或目录”，请帮帮我。谢谢。

控制器：

$path = base_path('storage/app/public/profile/');

$base = $request->picture;

$binary = base64_decode($base);

header('Content-Type: bitmap; charset=utf-8');

$f = finfo_open();

$mime_type = finfo_buffer($f, $binary, FILEINFO_MIME_TYPE);

$mime_type = str_ireplace('image/', '', $mime_type);

$filename = md5(\Carbon\Carbon::now()) . '.' . $mime_type;

$file = fopen($path . $filename, 'wb'); "this line throws that error"

if (fwrite($file, $binary)) {

    $user = User::find(auth()->id());
    $user->profile_image = 'profile/' . $filename;
    $user->save();

    return response()->json(array('result' => "yes"));
} else {
    return response()->json(array('result' => "no"));
}
fclose($file);
