用户程序guid有问题

Question

我正在this site上做练习。我完全遵循了这个示例，并且没有任何问题，直到我了解了上下文订阅：

(curl localhost:1026/v1/subscribeContext -s -S --header 'Content-Type: application/json' --header 'Accept: application/json' -d @- | python -mjson.tool) <<EOF
{
    "entities": [
        {
            "type": "Room",
            "isPattern": "false",
            "id": "Room1"
        }
    ],
    "attributes": [
        "temperature"
    ],
    "reference": "http://localhost:1028/accumulate",
    "duration": "P1M",
    "notifyConditions": [
        {
            "type": "ONTIMEINTERVAL",
            "condValues": [
                "PT10S"
            ]
        }
    ]
}
EOF

当我输入代码时，我得到了预期的答案：

{
    "subscribeResponse": {
        "duration": "P1M",
        "subscriptionId": "51c04a21d714fb3b37d7d5a7"
    }
}

但这句话让我很困惑：

If you look at the accumulator-script.py terminal window, you will see that a message resembling the following one is received each 10 seconds:

我在这里要做的是输入以下命令：python accumulator-server.py 但是我得到的输出（每10秒更新一次）是：127.0.0.1 - - [08/Apr/2015 10:52:56] "POST /accumulate HTTP/1.1" 200 -

因为我没有像教程中提到的那样获得预期的输出，所以我在这里遗漏了什么吗？你知道吗

POST http://localhost:1028/accumulate
Content-Length: 492
User-Agent: orion/0.9.0
Host: localhost:1028
Accept: application/xml, application/json
Content-Type: application/json

{
  "subscriptionId" : "51c04a21d714fb3b37d7d5a7",
  "originator" : "localhost",
  "contextResponses" : [
    {
      "contextElement" : {
        "attributes" : [
          {
            "name" : "temperature",
            "type" : "float",
            "value" : "26.5"
          }
        ],
        "type" : "Room",
        "isPattern" : "false",
        "id" : "Room1"
      },
      "statusCode" : {
        "code" : "200",
        "reasonPhrase" : "OK"
      }
    }
  ]
}

我是否没有正确运行python脚本？顺便说一句，我对python和linux都是新手。。。你知道吗

根据the manual，累加器的运行方式如下：

./accumulator-server.py 1028 /accumulate ::1 on
