我正在尝试在Go模板中显示二维码，但是显示变量有很大的问题。
如果我使用此变量{{.QRCodeURL}}，则输出如下：
data:image/png;base64,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
当我尝试以html代码显示图像时，示例代码：
<img src="{{.QRCodeURL}}" alt="qrcode" />
输出是这样的：
<img src="#ZgotmplZ" alt="qrcode" />
当我尝试以html内容打印时，不会打印变量的完整数据吗？我在哪里错了？
