laravel实现上传图片并在页面显示的例子
1:上传图片
publicfunctionupdateFeedbackImg(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'; $company->save(); return'{"statusCode":"200","message":"上传成功","navTabId":"uploadFeedbackImg","forwardUrl":"evaluation/queryCompanyFeedback/'.session('plan_id').'", "callbackType":"forward"}'; }else{ return'{"statusCode":"300","message":"上传失败","callbackType":"closeCurrent"}'; } }
2:html
picpath_)}}" οnclick="this.width+=500;this.height+=500;javascript:window.open(this.src);" style="cursor:pointer;width:500px;height:800px;border:1pxsolid#000000" name="photopath"/>
3:设置对应的路由
Route::group(['prefix'=>'evaluation'],function(){ //查看图片 Route::get('/lookthrough/{company_id}','EvaluationController@lookthrough'); //放大图片 Route::get('/showImage/{src}','EvaluationController@showImage'); });
4:显示图片
publicfunctionlookthrough($company_id) { $company=CompanyState::getRecordById($company_id); returnview('panels.EvaluationManagement.FeedbackInfo.FeedbackImg',['company'=>$company[0]]); } publicfunctionshowImage($src) { $path=storage_path().'/feedback/'.$src;//获取图片位置的方法 returnresponse()->file($path); }
