几周来,我一直在尝试使用apprtc在原生android应用程序(https://github.com/njovy/AppRTCDemo)和浏览器之间建立一个web会话。当使用appr.tc作为房间服务器url时,该应用程序运行得非常好。
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一个会议。但是当我试图在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?(这几乎是apprtchttps://github.com/webrtc/apprtc#deployment的部署过程)
从git下载了最新版本的apprtc
已安装的npm、nodejs和grunt
使用grunt build构建源代码
已下载、安装和配置对撞机(对撞机在RTC:8089上运行)
4.1我必须更改main.go in workspace/src/collidermain
发件人:var roomsrv=flag.string(“房间服务器”,“hxxps://appr.tc”,“房间服务器的来源”)
收件人:var roomsrv=flag.string(“房间服务器”,“hxxp://rtc”,“房间服务器的来源”)
4.2还将src/app_engine/constants.py中的ws_instance_host_key更改为colliders adresse rtc:8089
我安装了coturn并添加了一个turnserver.conf,看起来像
监听端口=3478
监听IP=192.168.178.20
用户=rtc:webrtc
证书=/home/rtc/work/src/collider/cert/cert.pem
pkey=/home/rtc/work/src/collider/cert/key.pem号
对撞机在192.168.178.20:8089(或RTC:8089)上运行,TurnServer在192.168.178.20:3478上运行。
turnserver.conf中定义的凭据:username=rtc,password=webrtc
安装之后,我将requesticeservers方法添加到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);
  });
}

并对标准方法进行了评述:
//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GAE,我的旋转服务器和对撞机
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(来自Collider Terminal的日志)
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 00:11:19 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,我总是收到上面提到的错误。
经过调查,我在git上找到了以下链接,但对我没有太大帮助:https://github.com/webrtc/apprtc/issues/366
所以我决定使用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"
#    ]
#  }
#]

所以我注释了turn_server_override=[]out,注释了其他行,并填写了turnserver的IP和在turnserver.conf中配置的凭据
gae意识到有一个新的请求即将到来。它日志

但还是犯了同样的错误。
因为这并没有起到什么作用,所以我尝试将turn server address插入到ice_server_base_url中(仍然是constants.py)
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

Error Screenshot 2
但现在我已经无法从浏览器打开主机。所以我想这可能是完全错误的。
你知道如何使用本机应用程序建立会议吗?
如何绕过networktraversal.googleapis.com的url
导致错误?
我必须绕过它吗?
提前谢谢!

最佳答案

将它们全部设置为空字符串:

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

你设置柯林德网址了吗?
你的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。更多细节。
