Question

自从几个星期以来，我一直试图通过使用apprtc在本机Android应用程序（https://github.com/njovy/AppRTCDemo）和浏览器之间建立websession。当使用appr.tc作为room-server url时，该应用程序运行良好。我已经在Ubuntu上设置了apprtc项目，并且我能够在Ubuntu机器上的浏览器和我的移动设备的浏览器之间创建会议。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

错误消息中提到的URL在src / app_engine / constants.py（https://github.com/webrtc/apprtc/blob/master/src/app_engine/constants.py）中定义。但我不知道如何处理它

# 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')
}

那我到目前为止做了什么？（它几乎是apprtc https://github.com/webrtc/apprtc#deployment）

的部署过程

从git
下载最新的apprtc版本
已安装npm，nodejs和grunt

使用grunt build构建源代码

下载，安装并配置对撞机（对撞机在rtc：8089上运行）

4.1我必须在workspace / src / collidermain中更改main.go    from： var roomSrv = flag.String（＆＃34; room-server＆＃34;，＆＃34; hxxps：//appr.tc"，＆＃34; the origin of the客房服务器＆＃34;）
   to： var roomSrv = flag.String（＆＃34; room-server＆＃34;，＆＃34; hxxp：// rtc＆＃34;，＆＃34;会议室服务器的来源＆＃34）

4.2在src / app_engine / constants.py
中将WS_INSTANCE_HOST_KEY更改为碰撞者adresse rtc：8089


我安装了CoTurn并添加了一个看起来像
的turnserver.conf   监听端口= 3478
  听-IP = 192.168.178.20
  用户= RTC：的WebRTC
  证书= /家庭/ RTC /工作/ src目录/撞机/ CERT / cert.pem
  p键= /家庭/ RTC /工作/ SRC /撞机/ CERT / key.pem

Collider在192.168.178.20:8089（或rtc：8089）上运行，而转向服务器在192.168.178.20:3478上运行。在turnserver.conf中定义的凭据：Username = rtc，Password = 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);
  });
}

并注释掉了标准方法：

//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;
    //});
  //});
//}

当我现在开始我的GAE，我的转弯服务器和对撞机

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（从对撞机终端登录）

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

当我现在尝试通过本机应用程序连接时，我总是收到上述错误。

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

所以我决定玩constants.py（https://github.com/webrtc/apprtc/blob/master/src/app_engine/constants.py）并找到一个覆盖Turn / Stun服务器的地方

# 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"
#    ]
#  }
#]

所以我评论了TURN_SERVER_OVERRIDE = [] out，评论了我的turnserver中的其他行并填写了我的凭据，在turnserver.conf中配置

GAE认识到该应用程序有新的请求。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。

由于这并没有做到这一点，我试图将转向服务器地址插入ICE_SERVER_BASE_URL（仍然在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')

已更改为

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

但现在我无法再通过浏览器打开主机了。因此，我猜它可能完全错了。

您是否知道如何使用原生应用程序建立会议？
如何绕过可能的networktraversal.googleapis.com网址导致错误？
我是否必须绕过它？

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 = ''

您设置了垃圾收集器网址吗？并且您的Turnserver应该使用oauth config。请查看以下所有日志：apprtc，chrome控制台日志，turnserver日志，collinder日志。以了解更多详细信息。
