取消订阅天鹅座 [英] Cancel Subscription on Cygnus

问题描述

我对MySql接收器的实体属性进行了订阅.问题是，当我测试我的休息服务以进行订阅(如果数据尚未持久)时，我进行了大量的订阅.现在，每次我对实体的属性进行更新时，都会发生一次，该值被保留了很多次.无论如何，是否可以删除没有subscriptionID的订阅?

I have a subscription made to an entity's attribute to a MySql sink. The problem is that while I was testing my rest service to do a subscription if the data was not yet persisted, i made a ton of subscriptions. Now every time I do an update on the entity's attribute what happens is that the value is persisted a lot of times. Is there anyway of deleting a subscription without the subscriptionID?

推荐答案

是的.首先，您可以使用GET /v2/subscriptions操作列出现有的订阅(查看 NGSIv2规范草案).

Yes, it is. First, you can list the existing subscriptions with the GET /v2/subscriptions operation (have a look to the draft NGSIv2 specification).

一旦有了ID，就会执行unsubscribeContext操作:

Once you have the IDs the unsubscribeContext operation:

(curl localhost:1026/v1/unsubscribeContext -s -S --header 'Content-Type: application/json' \
    --header 'Accept: application/json' -d @- | python -mjson.tool) <<EOF
{
    "subscriptionId": "51c0ac9ed714fb3b37d7d5a8"
}
EOF

我建议看看 Orion上下文代理文档.
