强制在浏览器中查看S3 PDF而不是下载 [英] Force S3 PDF to be viewed in browser instead of download

问题描述

因此您可以使用Content-Disposition: attachment

Content-Disposition: inline是默认设置，应显示在浏览器中，并且实际上适用于大多数文件，例如PNG，JPG等.

Content-Disposition: inline is the default and should display in the browser, and it does in fact work with most files like PNG, JPG, etc.

但是由于某种原因，从S3生成预签名URL时，即使我不使用content-disposition:附件标头，PDF文件也始终会强制下载.

But for some reason somehow when generating a presigned URL from S3, PDF files will always force download even if I don't use the content-disposition: attachment header.

我希望能够在浏览器允许的情况下在浏览器中打开PDF

I want to be able to make the PDF open in the browser when the browser allows it

我正在使用来自S3客户端 http:/的预签名URL生成调用/docs.aws.amazon.com/AmazonS3/latest/dev/ShareObjectPreSignedURLJavaSDK.html

I am using the presigned URL generate call from S3 client http://docs.aws.amazon.com/AmazonS3/latest/dev/ShareObjectPreSignedURLJavaSDK.html

推荐答案

检查文件的元数据，然后从该文件中删除 Content-Disposition 条目.并根据文件类型设置内容类型.

Check you file's metadata and remove Content-Disposition entry from that file. and set content type according to the file type.

喜欢 文本文件 Content-Type ='文本/纯文本

Like for text file Content-Type='text/plain'

image png 内容类型 ='image/png'

image png Content-Type='image/png'

pdf 内容类型 =应用程序/pdf

pdf Content-Type=application/pdf

pdfxml 内容类型 = application/vnd.adobe.pdfxml

pdfxml Content-Type=application/vnd.adobe.pdfxml

如果文件的Content-Type是二进制/八位字节流，那么它将下载而不是显示.

If your file's Content-Type is binary/octet-stream then it will download instead of display.
