laravel 上传图片后 页面显示

1:上传图片

 public function updateFeedbackImg(Request $request)
    {
        $bool = false;
        $upload_file = $request->file("pic");
        if ($upload_file->isValid()) {
            $realPath = $upload_file->getRealPath();
            $bool = Storage::disk('feedback')->put($request->get('id') . '.png', file_get_contents($realPath));
        }
        if ($bool == true) {
            $company = CompanyState::find($request->get('id'));
            $company->picpath_ = $request->get('id') . '.png';
            $company->save();
            return '{"statusCode":"200", "message":"上传成功", "navTabId":"uploadFeedbackImg", "forwardUrl":"evaluation/queryCompanyFeedback/' . session('plan_id') . '",
"callbackType":"forward"}';
        } else {
            return '{"statusCode":"300", "message":"上传失败","callbackType":"closeCurrent"}';
        }
    }

2:html

 <img src="{{ url('evaluation/showImage/'.$company->picpath_) }}"
         onclick="this.width+=500;this.height+=500; javascript:window.open(this.src);"
         style="cursor:pointer; width: 500px; height: 800px;border:1px solid #000000"
         name="photopath"/>

3:设置对应的路由

Route::group(['prefix' => 'evaluation'], function () {
   //查看图片
Route::get('/lookthrough/{company_id}', 'EvaluationController@lookthrough');
//放大图片
Route::get('/showImage/{src}', 'EvaluationController@showImage');
});

4：显示图片

  public function lookthrough($company_id)
    {
        $company = CompanyState::getRecordById($company_id);
        return view('panels.EvaluationManagement.FeedbackInfo.FeedbackImg', ['company' => $company[0]]);
    }
  public function showImage($src)
    {
        $path = storage_path() . '/feedback/' . $src;    //获取图片位置的方法
        return response()->file($path);
    }
