有内容类型但文件已下载

Question

我用这个从 S3direct 上传了文件。

image = forms.URLField(widget=S3DirectWidget(dest='images'), required=False)

文件正确上传到S3并登录浏览器控制台

而content-type设置为Content-Type image/jpeg

我也可以在 s3 aws-ui.

上检查这个

但是当我点击图片 url 时，它会下载。

除了Content-type浏览器选择下载还有其他原因吗？

我应该在哪里检查？

Answer 1

一个可能的问题是 Content-Disposition。在您的 S3 上传中，您应该添加：

ContentDisposition='inline'

这将设置适当的内容配置，以便直接在浏览器中查看。
