appr.tc的原生安卓应用程序

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会话。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上建立了apprtc项目，我可以在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

错误屏幕截图

错误消息中提到的URL在src/app_engine/contents.py(https://github.com/webrtc/apprtc/blob/master/src/app_engine/constants.py(中定义。但我不知道该怎么处理

# 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？(这几乎是近似https://github.com/webrtc/apprtc#deployment的部署过程(

从git下载apprtc的最新版本
已安装npm、nodejs和grunt
使用grunt构建构建资源
下载、安装和配置的对撞机(对撞机运行在rtc:8089上(
4.1我不得不在workspace/src/coldermain中更改我的main.go
来自：var roomSrv=标志。字符串("房间服务器"，"hxxps://appr.tc"，"房间服务器的起源"(
到：var roomSrv=标志。字符串("房间服务器"，"hxxp://rtc"，"房间服务器的来源"(
4.2还在src/app_engine/contents.py中将WS_INSTANCE_HOST_KEY更改为collapsers地址rtc:8089
我安装了CoTurn并添加了一个turnserver.conf，看起来像
侦听端口=3478
侦听ip=192.168.178.20
user=rtc:webrtc
cert=/home/rtc/work/src/colder/cert/cert.pem
pkey=/home/rtc/work/src/colder/cert/key.pem

Collider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：用户名=rtc，密码=webrtc

设置完成后，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(中

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);
  });
}

并指出了标准方法：

//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(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 00:11:09 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，我总是收到上面提到的错误。

经过调查，我在git上发现了以下链接，但它对我没有太大帮助：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(，并找到了一个覆盖转弯/特技服务器的地方

# 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，评论了其他行，并填写了我的turnserver的IP和我的凭据，在turnserver.conf 中配置

GAE意识到应用程序有一个新的请求。它记录

INFO     2016-11-05 00:06:31,649 apprtc.py:408] Added client 50600142 in room stackoverflow, retries = 0

但是仍然抛出相同的错误。

由于这也不起作用，我尝试将turn服务器地址插入ICE_server_BASE_URL(仍在常量.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

错误屏幕截图2

但现在我再也无法从浏览器打开主机了。所以我想这可能是完全错误的。

你知道如何使用本地应用程序建立会议吗
如何绕过networktraversal.googleapis.com URL导致错误的原因
我必须绕过它吗

提前感谢！

将它们全部设置为空字符串：

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

你设置了collinder url吗？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。
