我上Fiware实例安装天鹅版本0.8.2基础图像的CentOS-7-64使用：天鹅：坏HTTP通知（不支持卷曲/ 7.29.0用户代理）
sudo yum install cygnus
我配置我的代理人如下所示：
cygnusagent.sources = http-source
cygnusagent.sinks = mongo-sink
cygnusagent.channels = mongo-channel
#=============================================
# source configuration
# channel name where to write the notification events
cygnusagent.sources.http-source.channels = mongo-channel
# source class, must not be changed
cygnusagent.sources.http-source.type = org.apache.flume.source.http.HTTPSource
# listening port the Flume source will use for receiving incoming notifications
cygnusagent.sources.http-source.port = 5050
# Flume handler that will parse the notifications, must not be changed
cygnusagent.sources.http-source.handler = com.telefonica.iot.cygnus.handlers.OrionRestHandler
# URL target
cygnusagent.sources.http-source.handler.notification_target = /notify
# Default service (service semantic depends on the persistence sink)
cygnusagent.sources.http-source.handler.default_service = def_serv
# Default service path (service path semantic depends on the persistence sink)
cygnusagent.sources.http-source.handler.default_service_path = def_servpath
# Number of channel re-injection retries before a Flume event is definitely discarded (-1 means infinite retries)
cygnusagent.sources.http-source.handler.events_ttl = 10
# Source interceptors, do not change
cygnusagent.sources.http-source.interceptors = ts gi
# TimestampInterceptor, do not change
cygnusagent.sources.http-source.interceptors.ts.type = timestamp
# GroupinInterceptor, do not change
cygnusagent.sources.http-source.interceptors.gi.type = com.telefonica.iot.cygnus.interceptors.GroupingInterceptor$Builder
# Grouping rules for the GroupingInterceptor, put the right absolute path to the file if necessary
# See the doc/design/interceptors document for more details
cygnusagent.sources.http-source.interceptors.gi.grouping_rules_conf_file = /usr/cygnus/conf/grouping_rules.conf
# ============================================
# OrionMongoSink configuration
# sink class, must not be changed
cygnusagent.sinks.mongo-sink.type = com.telefonica.iot.cygnus.sinks.OrionMongoSink
# channel name from where to read notification events
cygnusagent.sinks.mongo-sink.channel = mongo-channel
# FQDN/IP:port where the MongoDB server runs (standalone case) or comma-separated list of FQDN/IP:port pairs where the MongoDB replica set members run
cygnusagent.sinks.mongo-sink.mongo_hosts = 127.0.0.1:27017
# a valid user in the MongoDB server (or empty if authentication is not enabled in MongoDB)
cygnusagent.sinks.mongo-sink.mongo_username =
# password for the user above (or empty if authentication is not enabled in MongoDB)
cygnusagent.sinks.mongo-sink.mongo_password =
# prefix for the MongoDB databases
cygnusagent.sinks.mongo-sink.db_prefix = kura_
# prefix pro the MongoDB collections
cygnusagent.sinks.mongo-sink.collection_prefix = kura_
# true is collection names are based on a hash, false for human redable collections
cygnusagent.sinks.mongo-sink.should_hash = false
#=============================================
# mongo-channel configuration
# channel type (must not be changed)
cygnusagent.channels.mongo-channel.type = memory
# capacity of the channel
cygnusagent.channels.mongo-channel.capacity = 1000
# amount of bytes that can be sent per transaction
cygnusagent.channels.mongo-channel.transactionCapacity = 100
我试图测试它在本地使用以下卷曲命令：
URL=$1
curl $URL -v -s -S --header 'Content-Type: application/json' --header 'Accept: application/json' --header "Fiware-Service: qsg" --header "Fiware-ServicePath: testsink" -d @- <<EOF
{
"subscriptionId" : "51c0ac9ed714fb3b37d7d5a8",
"originator" : "localhost",
"contextResponses" : [
{
"contextElement" : {
"attributes" : [
{
"name" : "temperature",
"type" : "float",
"value" : "26.5"
}
],
"type" : "Room",
"isPattern" : "false",
"id" : "Room1"
},
"statusCode" : {
"code" : "200",
"reasonPhrase" : "OK"
}
}
]
}
EOF
但我得到这个异常：

的什么都可以此异常的原因你知道吗？
