Orion Context Broker Fiware中的订阅 [英] Subscription in Orion Context Broker Fiware
问题描述
我尝试向我的Orion Context Broker实例发送订阅.我正在发送此JSON:
I try to send a subscription to my Orion Context Broker instance. I'm sending this JSON:
{
"duration": "P1M",
"reference": "http://130.206.127.23:1026/ngsi10/notifyContext",
"notifyConditions": [
{
"condValues": [
"PT10s"
],
"type": "ONTIMEINTERVAL"
}
],
"entities": [
{
"id": "1.0",
"type": "Capsule",
"isPattern": "false"
}
],
"attributes": [
"temperature"
]
}
然后我收到下一条消息:
And I receive the next message:
<subscribeContextResponse>
<subscribeError>
<errorCode>
<code>400</code>
<reasonPhrase>Bad Request</reasonPhrase>
<details>JSON Parse Error: <unspecified file>(1): invalid escape sequence</details>
</errorCode>
</subscribeError>
</subscribeContextResponse>
我将它使用的所有属性放在 Orion Context Broker网络研讨会-演示第2部分我可以看到其他名为Throttling
的属性,但在文档中却没有看到.
I put all attributes that it is using in the documentation. But in the webinar Orion Context Broker Webinar - Demo part 2 I can see other attribute called Throttling
, but I don't see in the documentation.
我在做什么不好?
谢谢.
推荐答案
我已经测试了您的请求(复制粘贴),这就是结果(使用Orion 0.17.0).
I have tested with your request (copy-pasted) and this is the result (with Orion 0.17.0).
命令(您可以检查有效载荷是否与您使用的有效载荷相同)
Command (you can check that the payload is exactly the one you used):
(curl localhost:1026/v1/subscribeContext -s -S --header 'Content-Type: application/json' --header 'Accept: application/json' -d @- | python -mjson.tool) <<EOF
{
"duration": "P1M",
"reference": "http://130.206.127.23:1026/ngsi10/notifyContext",
"notifyConditions": [
{
"condValues": [
"PT10s"
],
"type": "ONTIMEINTERVAL"
}
],
"entities": [
{
"id": "1.0",
"type": "Capsule",
"isPattern": "false"
}
],
"attributes": [
"temperature"
]
}
EOF
结果:
{
"subscribeResponse": {
"duration": "P1M",
"subscriptionId": "5489e0bfe5007d3271ab5a61"
}
}
因此,我的测试还可以,所以我倾向于认为该问题与编码有关,并且未在您的问题帖子中显示,例如的用法(错误的
"
intead)以及类似内容.
Thus, my test was ok so I tend to think that the problem is related with encoding and it is not shown in your question post, e.g. the usage of "
(wrong) intead of "
and things like that.
另一个常见的问题来源是使用脚本文件,该脚本文件包含"DOS文本"中CB的curl请求(通常是由于使用DOS/Windows文本编辑器).如果您运行file yourfile.sh
并获取以下内容,则可以轻松检测到此情况
another common source of problems is using script files containing the curl request to CB in "DOS text" (typically due to the usage of DOS/Windows text editors). This can be easility detected if you run file yourfile.sh
and get the following
yourfile.sh: ASCII text, with CRLF line terminators
代替以下
yourfile.sh: ASCII text
解决方案非常简单:例如使用dos2unix
命令行工具将文件转换为"Unix文本".
The solution is quite simple: transform the file to "Unix text", for example using the dos2unix
command line tool.
