我在 php 包含文件中获得了图像。

<img class="imgmove" src='data:image/png;base64,<?php echo base64_encode(file_get_contents("images/form/firstname.png")); ?>'>

代码完美无瑕。我正在测试设计并将图像拖到输入栏中,它会吐出以下内容:

这是您拖入的图像的 base64 数据 uri。据我了解,您的 php 文件没有问题。

您在图像上运行了 base64_encode。这就是 base64_encode 所做的,它将图像数据编码为 base64。您粘贴的是 base64 的样子。
