[Freeswitch-users] need help using http_cache + s3

[Dave Horton]

I’m having trouble using http_cache to download and play a wave file from my amazon S3 bucket.
I’m following the basic config at https://freeswitch.org/confluence/display/FREESWITCH/mod_http_cache but I must be missing something.

My http_cache.conf.xml looks like this:

———————————
<configuration name="http_cache.conf" description="HTTP GET cache">
  <settings>
    <!-- set to true if you want to enable http:// and https:// formats.  Do not use if mod_httapi is also loaded -->
    <param name="enable-file-formats" value="true"/>
    <param name="max-urls" value="10000"/>
    <param name="location" value="$${cache_dir}"/>
    <param name="default-max-age" value="86400"/>
    <param name="prefetch-thread-count" value="8"/>
    <param name="prefetch-queue-size" value="100"/>
    <!-- absolute path to CA bundle file -->
    <param name="ssl-cacert" value="$${certs_dir}/cacert.pem"/>
    <!-- verify certificates -->
    <param name="ssl-verifypeer" value="true"/>
    <!-- verify host name matches certificate -->
    <param name="ssl-verifyhost" value="true"/>
    <!-- default is 300 seconds, override here -->
    <!--param name="connect-timeout" value="300"/-->
    <!-- default is 300 seconds, override here -->
    <!--param name="download-timeout" value="300"/-->
  </settings>

    <profiles>
    <!-- amazon s3 security credentials -->
    <profile name="s3">
      <aws-s3>
        <!-- 20 character key identifier -->
        <access-key-id><![CDATA[my-access-key-here]]></access-key-id>
        <!-- 40 character secret -->
        <secret-access-key><![CDATA[my-secret-access-key-here]]></secret-access-key>
      </aws-s3>
      <!-- optional list of domains that this profile will automatically be applied to -->
      <!-- if you wish to apply the s3 credentials to a domain not listed here, then use
           {profile=s3}http://foo.s3... -->
      <domains>
        <domain name=“my-bucket.s3.amazonaws.com"/>
      </domains>
    </profile>
   </profiles>
</configuration>

My dialplan looks like this:

——————————————
   <extension name="announcement">
      <condition field="${sip_req_user}" expression="^annc$"/>
      <condition field="${sip_req_params}" expression="^play=(.*)$">
        <action application="log" data=“file to play: $1"/>
        <action application="answer"/>
        <action application="sleep" data="1000"/>
        <action application="playback" data="{profile=s3}http_cache://https://my-bucket.s3.amazonaws.com:/$1"/>
        <action application="hangup"/>
      </condition>
   </extension>

————————

I’ve fiddled with a bunch of different things, but no luck.  I took a tshark of the outgoing http get and I can see it is not putting in the headers to authenticate, so it seems it is not getting into 
the S3 code in http_cache.  The docs do not include a complete S3 working example, unfortunately.

Any help or pointers from those who have gotten this working would be appreciated…
