有誰知道如何在mysql中存儲圖像並使用angular和php顯示回來？

Question

我創建了一個網頁來顯示圖像，主題和詳細信息。 剛才我有一個靜態的html頁面，這只是一個頁面，我什么都沒有實現。

<section class="section-02">
        <div class="container">
    <h3>
            <div class="heading-large">Current Best</div>
          </h3>
    <div class="row">
            <div class="col-md-4">
        <div class="card"> <img class="img-fluid" src="img/media-1.jpg" alt="">
                <div class="card-block">
            <div class="news-title"><a href="#">
              <h2 class=" title-small">An Alternative Form of Mental Health Care Gains a Foothold</h2>
              </a></div>
            <p class="card-text"><small class="text-time"><em>3 mins ago</em></small></p>
          </div>
              </div>
        <ul class="news-listing">
                <li><a href="#">Key Republicans sign letter warning against candidate</a></li>
                <li><a href="#">Obamacare Appears to Be Making People Healthier</a></li>
                <li><a href="#">Syria war: Why the battle for Aleppo matters</a></li>
                <li><a href="#">‘S.N.L.’ to Lose Two Longtime Cast Members</a></li>
              </ul>
      </div>
            <div class="col-md-4">
        <div class="card"> <img class="img-fluid" src="img/media-2.jpg" alt="">
                <div class="card-block">
            <div class="news-title"><a href="#">

              </a></div>
            <p class="card-text"><small class="text-time"><em>3 mins ago</em></small></p>
          </div>
              </div>
        <ul class="news-listing">
                <li><a href="#">Syria war: Why the battle for Aleppo matters</a></li>

              </ul>
      </div>
            <div class="col-md-4">
        <div class="card"> <img class="img-fluid" src="img/media-3.jpg" alt="">
                <div class="card-block">

                <li><a href="#">Obamacare Appears to Be Making People Healthier</a></li>
                <li><a href="#">Syria war: Why the battle for Aleppo matters</a></li>
              </ul>
      </div>
          </div>
  </div>
      </section>

現在我想使用angular和php將其存儲在mysql數據庫中

Answer 1

盡管從技術上講可以將圖像存儲為BLOB類型，但我完全不建議您這樣做，而應該使用基於罐的文件系統，例如S3或服務器的本地文件系統。 只需將圖像的URI存儲在DB上即可。

在數據庫中存儲BLOBS將使其變慢，備份將花費更長的時間，並且必須優化查詢以避免檢索BLOB。 一個簡單的SELECT * FROM users; 如果您有成千上萬的用戶，可能會殺死您的數據庫。
