我正在将远程音频文件保存在Google云存储中。
我想在freeswitch中播放这些文件。

当我使用时:

mediaLink = "http://storage.googleapis.com/myBucket/file.wav";
session:streamFile(mediaLink);


它很棒。

但是当我使用签名网址

mediaLink = "http://storage.googleapis.com/myBucket/[email protected]&Expires=1408903962590&Signature=xxb%2Fx%2FDfGJlrUuz0%2F6kA6ormmReW6oN%2F0xxy3%2BwWxXc%3D";
session:streamFile(mediaLink);


我收到此错误:

2014-08-24 20:42:48.770818 [ERR] mod_httapi.c:2696 File at url [http://storage.googleapis.com/myBucket/[email protected]&Expires=1408903962590&Signature=xxb%2Fx%2FDfGJlrUuz0%2F6kA6ormmReW6oN%2F0xxy3%2BwWxXc%3D] is unreachable!


谢谢,

最佳答案

能够在FreeSWITCH 1.10上的playbackmod_dptools(用于mod_shout支持)中使它与mp3一起使用。目前,Google Storage signing algorithm也在V4上。

测试工作流程:


$ gsutil signurl -r us service-account.json gs://the-bucket/a-song.mp3

URL
gs://the-bucket/a-song.mp3

HTTP Method
GET

Expiration
2019-08-24 19:03:02

Signed URL
https://storage.googleapis.com/the-bucket/a-song.mp3?x-goog-signature=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&x-goog-algorithm=GOOG4-RSA-SHA256&x-goog-credential=name-of-the-service-account%2F20190824%2Fus%2Fstorage%2Fgoog4_request&x-goog-date=20190824T183009Z&x-goog-expires=3600&x-goog-signedheaders=host

playbackFreeSWITCH Lua API's IVRMenuexamples)(这里是full application code)一起使用:

-- signed URL above stripped of the URL scheme
local signed_url_without_url_scheme = "storage.googleapis..."

i.unregistered_main:bindAction(
  "menu-exec-app",
  "playback shout://" .. signed_url_without_url_scheme,
  "3"
)





我对streamFile没有运气,但这不是因为签名的URL,而是因为我什至无法使它工作。该文档非常参差不齐,某些部分甚至相互矛盾(例如,比较mod_shoutsession:streamFile)。

关于google-cloud-storage - freeswitch流远程音频文件,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/25474630/
