如何在HTML中显示Base64图像
提问于 2011-12-14 12:53:22
我在内联显示Base64图像时遇到问题。
我该怎么做呢？
<!DOCTYPE html>
<html>
<head>
<title>Display Image</title>
</head>
<body>
<img style='display:block; width:100px;height:100px;' id='base64image'
src='data:image/jpeg;base64, LzlqLzRBQ... <!-- Base64 data -->' />
</body>

我的疑犯当然是实际的Base64数据。不然的话，我觉得很不错。请参阅this fiddle，其中也有类似的方案。您可以尝试指定字符集。
<div>
<p>Taken from wikpedia</p>
<img src="data:image/png;base64, iVBORw0KGgoAAAANSUhEUgAAAAUA
AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO
9TXL0Y4OHwAAAABJRU5ErkJggg==" alt="Red dot" />
</div>
您可以尝试使用this Base64 decoder查看您的Base64数据是否正确。

如果你在后端有PHP，你可以使用下面的代码：
$image = 'http://images.itracki.com/2011/06/favicon.png';
// Read image path, convert to base64 encoding
$imageData = base64_encode(file_get_contents($image));
// Format the image SRC: data:{mime};base64,{data};
$src = 'data: ' . mime_content_type($image) . ';base64,' . $imageData;
// Echo out a sample image
echo '<img src="' . $src . '">';Stack Overflow用户

首先将您的图像转换为Base64 (编码为Base64)。您可以在线完成，也可以使用PHP脚本完成。
转换后，您将获得如下结果

您只需将其放入图像的src中，并按base64编码的形式在那里定义它。
