我已将我的Fiware结构移至Amazon EC2服务，我的代理配置如下：
cygnus-ngsi.sources = http-source
cygnus-ngsi.sinks = mongo-sink
cygnus-ngsi.channels = mongo-channel
cygnus-ngsi.sources.http-source.channels = mongo-channel

cygnus-ngsi.sources.http-source.handler = com.telefonica.iot.cygnus.handlers.NGSIRestHandler
cygnus-ngsi.sources.http-source.handler.notification_target = /notify
cygnus-ngsi.sources.http-source.handler.default_service = default
cygnus-ngsi.sources.http-source.handler.default_service_path = /sevilla
cygnus-ngsi.sources.http-source.handler.events_ttl = 2
cygnus-ngsi.sources.http-source.interceptors = ts
cygnus-ngsi.sources.http-source.interceptors.ts.type = timestamp

cygnus-ngsi.sinks.mongo-sink.enable_name_mappings = false
cygnus-ngsi.sinks.mongo-sink.enable_lowercase = false
cygnus-ngsi.sinks.mongo-sink.data_model = dm-by-service-path
cygnus-ngsi.sinks.mongo-sink.attr_persistence = column
cygnus-ngsi.sinks.mongo-sink.mongo_hosts = ******com:15959

cygnus-ngsi.sinks.mongo-sink.db_prefix = sth_
cygnus-ngsi.sinks.mongo-sink.collection_prefix = sth_
cygnus-ngsi.sinks.mongo-sink.batch_size = 1

cygnus-ngsi.sinks.mongo-sink.batch_ttl = 10

cygnus-ngsi.channels.mongo-channel.transactionCapacity = 11000
问题在于，当您将数据发送到MongoDB时，它不会将它们发送到代理中配置的服务路径，在cygnus.log中获取此响应
数据库：sth_default，Collection：sth_x002f srv =默认值| subsrv = /
会发生什么事情以致无法识别我的服务路径？
编辑：我把我的cygnus.log

解决方案：只需以这种方式为订阅添加标题并创建实体
$headers = array(
'Content-Type: application/json','Fiware-Service: default','Fiware-ServicePath: /mypath'
);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
答案 0 :(得分：1)
为避免覆盖在Cygnus中配置的Fiware-Service-Path和Fiware-Service的默认值，您必须在订阅请求中包含Headers Fiware-Service-Path和Fiware-Service及其相应的值。< / p>
