[PHP] Laravel框架实现文件上传的方法分析

'uplaods' => [
  'driver' => 'local',
  'root' => storage_path('app/uploads'),
],

<input type="file" name="headimg" />

$file = $request->file('headimg');
if($file && $file->isValid()){
//   //获取原图片信息
  $ext = $file->getClientOriginalExtension();
  $originalName = $file->getClientOriginalName();
  $type = $file->getClientMimeType();
  $path = $file->getRealPath();
  //验证图片类型，大小等
  //保存图片
  $save_name = date('YmdHis',time()) .'-' .uniqid() .'.'. $ext;
  $bool = Storage::disk('uploads')->put($save_name,file_get_contents($path));
  if(!$bool){
    return redirect()->back()->withErrors('图片上传失败')->withInput();
  }
}else{
  return redirect()->back()->withErrors('请上传图片')->withInput();
}
//如果验证通过，则继续执行下面的代码
$data = $request->input('Student');
//图片全路径
$img_web_path = storage_path('app/uploads') . '/' .$save_name;
//图片相对路径
$data['headimg'] = $save_name;
if(Student::create($data)){
  return redirect('Student/index')->with('success','添加成功');
}else{
  return redirect()->back();
}
