合肥光源的Chromecast的支持，在Amazon S3 CORS错误 [英] Chromecast support for HLS, CORS error on Amazon S3

问题描述

我试图整合HLS在我的Chromecast应用流。

该接收器部分是很好，因为我检查与多个HLS流网址。

我只是不能让CORS位正常运行。

我使用亚马逊的AWS S3。我已经设置了CORS我斗。

 ＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT; CORSConfiguration的xmlns =htt​​p://s3.amazonaws.com/doc/2006-03-01/＆GT;
    ＆LT; CORSRule＆GT;
        ＆LT; AllowedOrigin＆GT; *＆LT; / AllowedOrigin＆GT;
        ＆LT; AllowedMethod＆GT; GET＆LT; / AllowedMethod＆GT;
        ＆LT; AllowedMethod＆GT; PUT＆LT; / AllowedMethod＆GT;
        ＆LT; AllowedMethod＆GT; POST＆LT; / AllowedMethod＆GT;
        ＆LT; AllowedMethod＆GT;删除＆LT; / AllowedMethod＆GT;
        ＆LT; AllowedHeader＆GT; *＆LT; / AllowedHeader＆GT;
    ＆LT; / CORSRule＆GT;
＆LT; / CORSConfiguration＆GT;
 

在我的假设，这应该允许从所有域访问访问此桶内的资源。

不过还是我来自的Chromecast获得在javascript下面的错误。

  XMLHtt prequest无法加载http://s3-eu-west-1.amazonaws.com/interactive-encoding-out/watermark-sintel-test/playlist.m3u8 。没有访问控制 - 允许 - 原产地标头的请求的资源present。原产地https://s3-eu-west-1.amazonaws.com，因此不允许访问。
 

解决方案

现在，我已经使用corsproxy作为一个反向代理服务器，增加了CORS的头我的要求

。真是此推荐解决方案。无需自定义接收器应用这种方式。只是你的服务器上安装corsproxy地方

运行CORS代理：

  $ corsproxy＆LT; SERVER_IP＆GT; ＆LT; D​​ESIRED_PORT＆GT;
 

和运行类似的要求：

 的http：//＆LT; SERVER_IP＆GT;：＆LT; D​​ESIRED_PORT＆GT; /＆lt;您的请求＆GT;
 

从

安装： https://www.npmjs.org/package/corsproxy

I am trying to integrate HLS streams in my chromecast app.

The receiver part is fine because i checked it with multiple HLS Stream urls.

i just cant get the CORS bit to operate correctly.

I am using Amazon AWS S3. I have set the CORS for my bucket.

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
    <CORSRule>
        <AllowedOrigin>*</AllowedOrigin>
        <AllowedMethod>GET</AllowedMethod>
        <AllowedMethod>PUT</AllowedMethod>
        <AllowedMethod>POST</AllowedMethod>
        <AllowedMethod>DELETE</AllowedMethod>
        <AllowedHeader>*</AllowedHeader>
    </CORSRule>
</CORSConfiguration>

in my assumption this should allow access from all domains to access the resources inside this bucket.

But still i am getting the following error in javascript from Chromecast.

XMLHttpRequest cannot load http://s3-eu-west-1.amazonaws.com/interactive-encoding-out/watermark-sintel-test/playlist.m3u8. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://s3-eu-west-1.amazonaws.com' is therefore not allowed access. 

解决方案

Right now i have used corsproxy as a reversed proxy that adds cors headers to my request. Really recommand this solution. No need for a custom receiver app this way. just install the corsproxy somewhere on your server

run the cors proxy:

$ corsproxy <SERVER_IP> <DESIRED_PORT>

and run the request like :

http://<SERVER_IP>:<DESIRED_PORT>/<YOUR REQUEST>

install from: https://www.npmjs.org/package/corsproxy
