我正在使用Php和Angular构建项目,我可以将文件上传到本地数据库,我可以检索文件信息。我不知道如何检索文件本身并将其下载到我的电脑。有人可以帮忙吗? 在数据库中 - 列/ type = id-int,name-varchar,mime-longblob,size-biginet,data-mediumblob,created-datetime

用于检索文件详细信息的Php:

  header('Content-Type: text/html; charset=utf-8');

  $connection = mysqli_connect('localhost', 'root', '', 'hamatkin');

  mysqli_query($connection, "SET character_set_client = utf8");
  mysqli_query($connection, "SET character_set_connection = utf8");
  mysqli_query($connection, "SET character_set_results = utf8");

  if (!$connection) {
    die("couldnt connect".mysqli_error);
  }

  $query = "SELECT id, name, created FROM file";
  $queryResult = $connection->query($query);

  $queryResult2 = array();

  if ($queryResult === false) {
    die($connection->error);
  }

  if ($queryResult->num_rows > 0) {
    while ($row = $queryResult->fetch_assoc()) {
      $queryResult2[] = $row;
    }
  }

  $queryResult3 = json_encode($queryResult2);

  echo json_encode($queryResult2);

控制器:

“use strict”;

angular.module('dataSystem').controller('allPriceOffersCtrl', function($scope,$route,$location,$http) {
  $http({method:'GET', url:'api/customers-tab/get-all-priceOffers.php/'})
      .then(function(response) {
        var arr = response.data;
        $scope.files = arr;
      })
      // This will log you the error code and trace, if there is an error.
      .catch(function(err) {
        console.log('err', err)
      });

});

HTML:

<div class="table-responsive">
  <table  class="customer-list table table-striped">
    <thead>
      <tr>
        <!-- <th>#</th> -->
        <th class="Column-Header"> מספר קובץ הצעת מחיר</th>
        <th class="Column-Header">שם הקובץ</th>
        <th class="Column-Header">תאריך</th>

      </tr>
    </thead>
    <tbody>
      <tr ng-repeat="x in files ">
        <!-- <td>{{$index + 1}}</td> -->
        <td>{{ x.id}}</td>
        <td>{{ x.name}}</td>
        <td> {{ x.created}} </td>
      </tr>
    </tbody>
  </table>
</div>

更好的解决方案是将文件上传到服务器并添加.htaccess以限制访问,将文件重命名为序列号,这样两个具有相同名称的文件永远不会覆盖并存储包含filename.extension(相对文件)的文件路径来自网站的路径),serialNo。作为文件的id和实名(带扩展名)。根据需要填充路径并在下载前重命名。
