Google文档查看器不适用于Amazon s3签名的网址 [英] Google doc viewer doesn't work with Amazon s3 signed urls

问题描述

我尝试在iframe中显示存储在S3内存中的.doc文件，这要感谢google doc viewer api。

href =http://www.bitesite.ca/blog_posts/17 =nofollow noreferrer>这是我试图在这里申请的内容：

  var encodedUrl = encodeURIComponent（http://myAPI.com/1d293950-67b2-11e7-8530-318c83fb9802/example.docx?X-Amz-Algorithm=AWS4-HMAC-SHA256 ％26X-AMZ-凭证= GNRO0BLDYAJP1FU7ALIS％2F20170717％2Fus  - 东 -  1％2Fs3％2Faws4_request％26X-AMZ-日期= 20170717T145429Z％26X-AMZ-到期= 600％26X-AMZ-SignedHeaders =主机％26X-AMZ签名= ee556c5c92427bb38265507218a701660936bc2774ecc919648bb2d780a2619f）; 
 
 $ scope.selectedSource = $ sce.trustAsResourceUrl（
http://docs.google.com/gview?url=+ encodedUrl +& embedded = true
）; 
  

Iframe看起来像：

 < iframe ng-src ={{selectedSource}}frameborder =nostyle =width：100％; height：100％>< / iframe> 
  

但是我仍然在iframe中看到No Preview Available，有什么想法？

我指定当我将它粘贴到浏览器中时，已签名的url（未编码）有效，因此我拥有所有需要的权限。

解决方案

检查专门针对Amazon s3签名url的解决方案。基本上它用于查看使用Google Docs Viewer的私人文档

带有Amazon S3私人文档和预定网址的Google文档查看器

I try to display a .doc file stored on a S3 bucket inside an iframe thanks to google doc viewer api.

I already did some research and found this, which i tried to apply here :

var encodedUrl = encodeURIComponent("http://myAPI.com/1d293950-67b2-11e7-8530-318c83fb9802/example.docx?X-Amz-Algorithm=AWS4-HMAC-SHA256%26X-Amz-Credential=GNRO0BLDYAJP1FU7ALIS%2F20170717%2Fus-east-1%2Fs3%2Faws4_request%26X-Amz-Date=20170717T145429Z%26X-Amz-Expires=600%26X-Amz-SignedHeaders=host%26X-Amz-Signature=ee556c5c92427bb38265507218a701660936bc2774ecc919648bb2d780a2619f");

$scope.selectedSource = $sce.trustAsResourceUrl(
   "http://docs.google.com/gview?url=" + encodedUrl + "&embedded=true"
);

Iframe looks like :

<iframe ng-src="{{selectedSource}}" frameborder="no" style="width:100%;height:100%"></iframe>

But i still get a "No Preview Available" from the viewer inside the iframe , any idea why ?

I specify that the signed url (not encoded) works when I paste it in my browser, so I have all the rights needed.

解决方案

Check the solution specifically for Amazon s3 signed urls. Basically its for viewing private documentation using Google Docs Viewer
