问题描述
我正在使用Twilio构建一个简单的联络中心应用程序。 我正在后端中创建TaskRouter Worker功能令牌,如下所示: 序列化器:
class TwilioTokenSerializer(serializers.BaseSerializer):
def to_representation(self,instance):
return {
'token': instance,}
查看:
class TwilioWorkerView(generics.RetrieveAPIView):
serializer_class = TwilioTokenSerializer
def get_object(self):
current_user = self.request.user.worker
worker_sid = current_user.worker_sid
# Returns a Twilio Worker token for current agent
capability = WorkerCapabilityToken(
account_sid=TWILIO_ACCOUNT_SID,auth_token=TWILIO_AUTH_TOKEN,workspace_sid=TWILIO_WORKSPACE_SID,worker_sid=worker_sid
)
capability.allow_fetch_subresources()
capability.allow_update_activities()
capability.allow_update_reservations()
token = capability.to_jwt()
token = capability.to_jwt(ttl=28800)
return token
反应中:
import { Worker } from 'twilio-taskrouter';
componentDidMount(){
axios.get('https://myURL.com/api/twilio-worker-token')
.then(res =>{
console.log(res.data.token)
const worker = new Worker(res.data.token)
}).catch(error =>{
console.log(error)
})

相同的设置可以与带有taskrouter的cdn的html一起很好地工作 我在使用cdn和react twilio-taskrouter库时的区别是Web套接字url,而后者则既不包含帐户SID,也不包含工作程序SID。
我想念什么?
解决方法
我明白了,我在 twilio-taskrouter库中使用了错误的令牌,我应该在访问令牌中使用 TaskRouter Grant (而不是使用 TaskRouter Worker功能令牌)。
class TwilioWorkerView(generics.RetrieveAPIView):
serializer_class = TwilioTokenSerializer
def get_object(self):
current_user = self.request.user
username = current_user.username
agent_sid = current_user.agent.agent_sid
access = AccessToken(TWILIO_ACCOUNT_SID,TWILIO_API_KEY,TWILIO_API_SECRET)
taskrouter_grant = TaskRouterGrant(workspace_sid=TWILIO_WORKSPACE_SID,worker_sid=agent_sid,role='worker')
access.add_grant(taskrouter_grant)
access.identity = username
token = access.to_jwt()
return token
