有谁知道如何在mysql中存储图像并使用angular和php显示回来？

Question

我创建了一个网页来显示图像，主题和详细信息。 刚才我有一个静态的html页面，这只是一个页面，我什么都没有实现。

<section class="section-02">

现在我想使用angular和php将其存储在mysql数据库中

Answer 1

尽管从技术上讲可以将图像存储为BLOB类型，但我完全不建议您这样做，而应该使用基于罐的文件系统，例如S3或服务器的本地文件系统。 只需将图像的URI存储在DB上即可。

在数据库中存储BLOBS将使其变慢，备份将花费更长的时间，并且必须优化查询以避免检索BLOB。 一个简单的SELECT * FROM users; 如果您有成千上万的用户，可能会杀死您的数据库。
