我正在使用Fiware-Orion ContextBroker 0.28，在我的本地主機上的dockerized版本在Ubuntu 15.10 64位。訂閱似乎無法使用dockerized fiware-orion
$ curl localhost:1026/version
{
"orion" : {
"version" : "0.28.0-next",
"uptime" : "0 d, 0 h, 0 m, 6 s",
"git_hash" : "067e13618c247daa4af61f82d7831f3015d9eb5d",
"compile_time" : "Mon Mar 14 13:04:02 UTC 2016",
"compiled_by" : "root",
"compiled_in" : "838a42ae8431"
}
}
我使用的泊塢窗的配置是：
$ cat docker-compose.yml
mongo:
image: mongo:2.6
command: --smallfiles --nojournal
orion:
image: fiware/orion
links:
- mongo
ports:
- "1026:1026"
command: -dbhost mongo
我從獵戶座/泊塢窗得到警告，當我做的訂購：
orion_1 | [email protected]:19:14 AlarmManager.cpp[303]: Raising alarm NotificationError localhost:1028/accumulate: (curl_easy_perform failed: Couldn't connect to server)
我正在關注的API V1 walkthorugh來測試對更改的訂閱。我從一個薄荷新的dockerized（sudo docker-組成和所有模糊的）fiware-orion 0.28與mongodb開始。然後，我開始蓄
$ ./accumulator-server.py 1028 /accumulate localhost on
verbose mode is on
* Running on http://localhost:1028/ (Press CTRL+C to quit)
然後我註冊房間1
$ (curl localhost:1026/v1/updateContext -s -S --header 'Content-Type: application/json' \
> --header 'Accept: application/json' -d @- | python -mjson.tool) <<EOF

{
"contextResponses": [
{
"contextElement": {
"attributes": [
{
"name": "temperature",
"type": "float",
"value": ""
},
{
"name": "pressure",
"type": "integer",
"value": ""
}
],
"id": "Room1",
"isPattern": "false",
"type": "Room"
},
"statusCode": {
"code": "200",
"reasonPhrase": "OK"
}
}
]
}
然後我測試查詢上下文只是爲了檢查：
$ (curl localhost:1026/v1/queryContext -s -S --header 'Content-Type: application/json' \
> --header 'Accept: application/json' -d @- | python -mjson.tool) <<EOF
> {
> "entities": [

> }
> ]
> }
> EOF
{
"contextResponses": [
{
"contextElement": {
"attributes": [
{
"name": "pressure",
"type": "integer",
"value": "720"
},
{
"name": "temperature",
"type": "float",
"value": "23"
}
],
"id": "Room1",
"isPattern": "false",
"type": "Room"
},
"statusCode": {
"code": "200",
"reasonPhrase": "OK"
}
}
]
}
然後我做的認購
$ (curl localhost:1026/v1/subscribeContext -s -S --header 'Content-Type: application/json' \
> --header 'Accept: application/json' -d @- | python -mjson.tool) <<EOF
> {
> "entities": [

> "id": "Room1"

> "attributes": [
> "pressure"
> ],
> "reference": "http://localhost:1028/accumulate",
> "duration": "P1M",
> "notifyConditions": [
> {
> "type": "ONCHANGE",
> "condValues": [
> "pressure"
> ]
> }
> ],
> "throttling": "PT5S"
> }
> EOF
{
"subscribeResponse": {
"duration": "P1M",
"subscriptionId": "570f8ac247fcf8a62722353c",
"throttling": "PT5S"
}
}
在這一點上的男人ual表示累加器可能會收到第一次更新，但不是必需的，所以我什麼都沒收到，但也許沒關係。或者，也許不會，因爲發送了預訂查詢後，獵戶座的搬運工說：
orion_1 | [email protected]:19:14 AlarmManager.cpp[303]: Raising alarm NotificationError localhost:1028/accumulate: (curl_easy_perform failed: Couldn't connect to server)
最後，我更新的實體，我應該得到的蓄能器的更新，但我不：
$ (curl localhost:1026/v1/updateContext -s -S --header 'Content-Type: application/json' \
> --header 'Accept: application/json' -d @- | python -mjson.tool) <<EOF
> {

> "attributes": [

> "type": "float",
> "value": "56.5"
> },
> {
> "name": "pressure",
> "type": "integer",
> "value": "553"
> }
> ]
> }
> ],
> "updateAction": "UPDATE"
> }
> EOF
{
"contextResponses": [
{
"contextElement": {
"attributes": [
{
"name": "temperature",
"type": "float",
"value": ""
},
{
"name": "pressure",
"type": "integer",
"value": ""
}
],
"id": "Room1",
"isPattern": "false",
"type": "Room"
},
"statusCode": {

"reasonPhrase": "OK"
}
}
]
}
我也應該說，要在Ubuntu上編譯fiware-orion是非常困難的，這就是我使用docker的原因。
只有在CentOS上才支持編譯Orion，不過在Ubuntu上進行微小的更改應該不會太難。 – LeandroGuillen
