android - 适用于 appr.tc 的 native android 应用程序

Question

几周以来，我一直在尝试使用 apprtc 在原生 android 应用程序 (https://github.com/njovy/AppRTCDemo) 和浏览器之间建立网络 session 。当使用 appr.tc 作为房间服务器 url 时，该应用程序运行良好。 我已经在 Ubuntu 上设置了 apprtc 项目，我能够在 Ubuntu 机器上的浏览器和例如我的移动设备的浏览器之间创建 session 。但是当我尝试在 ubuntu 上的浏览​​器和应用程序之间建立连接时，我总是收到以下错误:

Room IO error: java.io.IOException:
Non-200 response when requesting 
TURN server from https://
networktraversal.googleapis.com/
v1alpha/iceconfig?key=none : HTTP/
1.1 400 Bad Request

Error-Screenshot

错误信息中提到的URL定义在src/app_engine/constants.py (https://github.com/webrtc/apprtc/blob/master/src/app_engine/constants.py).但是我不知道该怎么办

# TODO(jansson): Remove once AppRTCDemo on iOS supports ICE_SERVER.
TURN_BASE_URL = 'https://computeengineondemand.appspot.com'
TURN_URL_TEMPLATE = '%s/turn?username=%s&key=%s'
CEOD_KEY = '4080218913'

ICE_SERVER_BASE_URL = 'https://networktraversal.googleapis.com'
ICE_SERVER_URL_TEMPLATE = '%s/v1alpha/iceconfig?key=%s'
ICE_SERVER_API_KEY = os.environ.get('ICE_SERVER_API_KEY')

CALLSTATS_PARAMS = {
  'appId': os.environ.get('CALLSTATS_APP_ID'),
  'appSecret': os.environ.get('CALLSTATS_APP_SECRET')
}

到目前为止我做了什么？ (差不多就是apprtc https://github.com/webrtc/apprtc#deployment的部署过程)

1. Downloaded the latest verion of apprtc from git
2. Installed npm, nodejs and grunt
3. Building sources by using grunt build
4. Downloaded, installed and configured collider (collider runs on rtc:8089)
   • 4.1 I had to change my main.go in workspace/src/collidermain
     from: var roomSrv = flag.String("room-server", "hxxps://appr.tc", "The origin of the room server")
     to: var roomSrv = flag.String("room-server", "hxxp://rtc", "The origin of the room server")
   • 4.2 Also changed WS_INSTANCE_HOST_KEY to colliders adresse rtc:8089 in src/app_engine/constants.py
5. I installed CoTurn and added a turnserver.conf that looks like
   listening-port=3478
   listening-ip=192.168.178.20
   user=rtc:webrtc
   cert=/home/rtc/work/src/collider/cert/cert.pem
   pkey=/home/rtc/work/src/collider/cert/key.pem

Collider 在 192.168.178.20:8089(或 rtc:8089)上运行，而 turnserver 在 192.168.178.20:3478 上运行。 turnserver.conf中定义的凭证:用户名=rtc，密码=webrtc

设置完成后，我将 requestIceServers-Method 添加到 src/web_app/js/util.js (https://github.com/webrtc/apprtc/blob/master/src/web_app/js/util. js)

function requestIceServers(iceServerRequestUrl, iceTransports) {
  return new Promise(function(resolve, reject) {
    var servers = [{
        credential: "webrtc",
        username: "rtc",
        urls: [
          "turn:192.168.178.20:3478?transport=udp",
          "turn:192.168.178.20:3478?transport=tcp"
        ]
    }];
    resolve(servers);
  });
}

并注释掉标准方法:

//function requestIceServers(iceServerRequestUrl, iceTransports) {
  //return new Promise(function(resolve, reject) {
    //sendAsyncUrlRequest('POST', iceServerRequestUrl).then(function(response) {
      //var iceServerRequestResponse = parseJSON(response);
      //if (!iceServerRequestResponse) {
        //reject(Error('Error parsing response JSON: ' + response));
        //return;
      //}
      //if (iceTransports !== '') {
        //filterIceServersUrls(iceServerRequestResponse, iceTransports);
      //}
      //trace('Retrieved ICE server information.');
      //resolve(iceServerRequestResponse.iceServers);
    //}).catch(function(error) {
      //reject(Error('ICE server request error: ' + error.message));
      //return;
    //});
  //});
//}

当我现在启动我的 GAE、我的 turnserver 和 collider 时

python ~/google_appengine/dev_appserver.py ~/google_projects/apprtc-master/out/app_engine --host=0.0.0.0
sudo turnserver -a -r 192.168.178.20
$GOPATH/bin/collidermain -port=8089 -tls=false

我能够在两个浏览器客户端之间建立连接(从 collider-terminal 登录)

rtc@rtc:~$ $GOPATH/bin/collidermain -port=8089 -tls=false
2016/11/05 00:07:32 Starting collider: tls = false, port = 8089, room-server=http://rtc
2016/11/05 00:10:24 Created room stackoverflow

2016/11/05 00:10:24 Client 97869213 registered in room stackoverflow
2016/11/05 00:10:57 Added client 96368166 to room stackoverflow
2016/11/05 00:10:57 Client 96368166 registered in room stackoverflow
2016/11/05 00:10:57 Sent queued messages from 97869213 to 96368166
2016/11/05 00:11:09 Deregistered client 96368166 from room stackoverflow
2016/11/05 00:11:09 Removed client 96368166 from room stackoverflow
2016/11/05 00:11:19 Removing client 96368166 from room stackoverflow due to timeout

当我现在尝试通过 native 应用程序连接时，我总是收到上述错误。

经过调查，我在 git 上找到了以下链接，但对我帮助不大:https://github.com/webrtc/apprtc/issues/366

所以我决定尝试使用 constants.py (https://github.com/webrtc/apprtc/blob/master/src/app_engine/constants.py) 并找到了一个地方在哪里覆盖 Turn/Stun 服务器

# Turn/Stun server override. This allows AppRTC to connect to turn servers
# directly rather than retrieving them from an ICE server provider.
TURN_SERVER_OVERRIDE = []
# Enable by uncomment below and comment out above, then specify turn and stun
# servers below.
#TURN_SERVER_OVERRIDE = [
#  {
#    "urls": [
#      "turn:192.168.178.20:3478?transport=udp",
#      "turn:192.168.178.20:3478?transport=tcp"
#    ],
#    "username": "rtc",
#    "credential": "webrtc"
#  },
#  {
#    "urls": [
#      "stun:stun.l.google.com:19305"
#    ]
#  }
#]

所以我将 TURN_SERVER_OVERRIDE = [] 注释掉，注释掉其他行并填写我的 turnserver 的 IP 和我的凭据，在 turnserver.conf 中配置

GAE 意识到应用程序收到了新请求。它记录

INFO     2016-11-05 00:06:31,649 apprtc.py:408] Added client 50600142 in room stackoverflow, retries = 0
INFO     2016-11-05 00:06:31,650 apprtc.py:92] Applying media constraints: {'video': True, 'audio': True}

但仍然会抛出相同的错误。

因为这也不起作用，所以我尝试将 turn-server 地址插入 ICE_SERVER_BASE_URL(仍在 constants.py 中)

ICE_SERVER_BASE_URL = 'https://networktraversal.googleapis.com'
ICE_SERVER_URL_TEMPLATE = '%s/v1alpha/iceconfig?key=%s'
ICE_SERVER_API_KEY = os.environ.get('ICE_SERVER_API_KEY')

改为

ICE_SERVER_BASE_URL = '192.168.178.20:3478'
ICE_SERVER_URL_TEMPLATE = ''
ICE_SERVER_API_KEY = os.environ.get('ICE_SERVER_API_KEY')

这将错误更改为:

Connection error
Non-200 response to POST to URL:
http://rtc:8080/join/stackoverflow=wstls=false : HTTP/1.1 500 Internal 
Server Error

但现在我无法再从浏览器打开主机。因此我想这可能是完全错误的。

• 您知道如何使用 native 应用程序建立 session 吗？
• 如何绕过 networktraversal.googleapis.com 网址 导致错误？
• 我必须绕过它吗？

提前致谢!

Answer 1

将它们全部设置为空字符串:

ICE_SERVER_BASE_URL = ''
ICE_SERVER_URL_TEMPLATE = ''
ICE_SERVER_API_KEY = ''

你设置collinder url了吗？ 并且您的 turnserver 应该使用 oauth 配置。 检查所有日志:apprtc、chrome 控制台日志、turnserver 日志、collinder 日志.. 了解更多详细信息。
