Question

我有一个网站satoshirps.site

当新用户注册时，他的个人资料照片仍为空。然后转到Upload picture上传个人资料照片。

返回仪表板（www.satoshirps.site/dashboard）后，用户可以看到他上传的个人资料照片。现在转到delete picture删除当前的个人资料照片，然后使用上传上传另一个个人资料照片。

这次返回仪表板会给出旧图片（这很奇怪）。

当我尝试这件事时，我第二次成功上传了图片（我在我的应用程序文件夹中检查了文件）。然后我没有得到正确的图像。 lavarel是否有缓存或这是一个cookie问题。我再次尝试删除浏览器的缓存和cookie，但没有任何效果。

上传页面：

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>Upload</title>
</head>
<body>
  @if(Session::has('success'))
      {{ Session::get('success') }}
@endif

@if(Session::has('error'))
        {{ Session::get('error') }}
@endif

  {{ Form::open(array('url' => 'upload', 'files' => true, 'method' => 'post')) }}
  {!! csrf_field() !!}
  {{ Form::file('image') }}
  {{ Form::submit('Upload') }}
  {{ Form::close() }}
</body>
</html>

控制器

<?php

namespace App\Http\Controllers;

use App\Http\Requests;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Input;
use Session;
use Redirect;
use Image;
use Storage;
use App\User;
use File;


class HomeController extends Controller
{
  /**
  * Create a new controller instance.
  *
  * @return void
  */
  public function __construct()
  {
    $this->middleware('auth');
  }

  /**
  * Show the application dashboard.
  *
  * @return \Illuminate\Http\Response
  */
  public function index()
  {
    return view('home');
  }

  public function dashboard()
  {
    $user = Auth::user();
    return view('dashboard', compact('user'));
  }

  public function upload()
  {
    $user = Auth::user();
    return view('upload', compact('user'));
  }

  public function uploadsave(Request $request)
  {
    $user = Auth::user();
    if (Input::file('image')->isValid()) {
      $filename = 'profilepics/'.$user->username.'.jpg';
      File::delete($filename);
      $img = Image::make($_FILES['image']['tmp_name'])->encode('jpg',75)->resize(200,200)->save('profilepics/'.$user->username.'.jpg');
      $dbuser = User::where('id', $user->id)->first();
      $dbuser->photo_path = '/profilepics/'.$user->username.'.jpg';
      $dbuser->save();  //update user's profile picture location
      Session::flash('success', 'Upload successfull');
      return Redirect::to('upload');
    }
    else {
      // sending back with error message.
      Session::flash('error', 'Uploaded file is not valid');
      return Redirect::to('upload');
    }
  }


  public function deletephoto()
  {
    $user = Auth::user();
    $filename = 'profilepics/'.$user->username.'.jpg';
    File::delete($filename);
    if (file_exists($filename)) {
      echo "The image is not deleted";
    } else {
      echo "The image is deleted";
    }
  }
}

路线档案

<?php
Route::get('/', function () {
  return view('welcome');
});
Route::group(['middleware' => 'web'], function () {
  Route::auth();
  Route::get('/home', 'HomeController@index');
  Route::get('/dashboard', 'HomeController@dashboard');
  Route::get('/upload', 'HomeController@upload');
  Route::post('/upload', 'HomeController@uploadsave');
  Route::get('delete', 'HomeController@deletephoto');
});

此外，如果您在删除文件后访问仪表板，您将看到旧的个人资料图片

请有人请试试并帮助我。

从the documentation，要删除文件，您应该使用Storage::delete($filename)

将照片保存在存储目录中，并通过在UsersController中创建以下路线来提供照片：

public function profilePicture($user){
    $profile_picture_url = storage_path().'/profile_pictures/'.$user['id'].'/profile.jpg';

    if(!File::exists( $profile_picture_url ))
        App::abort(404);

    return Image::make($profile_picture_url)->response('jpg');
}

然后，在您的视图中，使用来自Laravel的HTML和URL帮助程序创建img标记：

HTML::image(URL::action('UsersController@profilePicture', array($user['id'])))

确保安装了Intervention package并且您很高兴

Laravel表现得很疯狂 - 显示错误的图像
