如何以编程方式启用/禁用 Azure 功能 [英] How to Enable/Disable Azure Function programmatically

问题描述

有没有办法以编程方式启用/禁用 Azure 功能?

Is there a way to programmatically enable/disable an Azure function?

我可以使用管理"部分下的门户启用/禁用功能，这会导致将请求发送到 https://<myfunctionapp>.scm.azurewebsites.net/api/functions/<我的功能>

I can enable/disable a function using the portal under the "Manage" section, which causes a request to be sent to https://<myfunctionapp>.scm.azurewebsites.net/api/functions/<myfunction>

JSON 负载看起来有点像:

The JSON payload looks a bit like:

{
   "name":"SystemEventFunction",
   "config":{
      "disabled":true,
      "bindings":[ 
         // the bindings for this function
       ]
   }
  // lots of other properties (mostly URIs)
}

我正在门户之外创建一个管理工具，允许用户启用和禁用功能.

I'm creating a management tool outside of the portal that will allow users to enable and disable functions.

希望我可以避免手动创建 JSON 负载，所以我想知道 SDK(WebJobs??)中是否有具有此功能的东西.

Hoping I can avoid creating the JSON payload by hand, so I'm wondering if there is something in an SDK (WebJobs??) that has this functionality.

推荐答案

不，这目前是不可能的.function.json 中的 disabled 元数据属性决定了某个功能是否启用.当您在门户中启用/禁用时，门户只会更新该值.

No, this is not possible currently. The disabled metadata property in function.json is what determines whether a function is enabled. The portal just updates that value when you enable/disable in the portal.

不确定它是否能满足您的需求，但我会指出还有一个 host.json functions 数组可用于控制将要加载的函数集(记录在此处).因此，例如，如果您只希望启用 10 个函数中的 2 个，则可以将此属性设置为仅包含这 2 个函数名称的数组(例如 "functions": [ "QueueProcessor", "GitHubWebHook" ])，并且只有那些会被加载/启用.但是，这与启用/禁用略有不同，因为您将无法通过门户调用排除的功能，而您可以通过门户调用禁用功能.

Not sure if it will meet your needs, but I'll point out that there is also a host.json functions array that can be used to control the set of functions that will be loaded (documented here). So for example, if you only wanted 2 of your 10 functions enabled, you could set this property to an array containing only those 2 function names (e.g. "functions": [ "QueueProcessor", "GitHubWebHook" ]), and only those will be loaded/enabled. However, this is slightly different than enable/disable in that you won't be able to invoke the excluded functions via the portal, whereas you can portal invoke disabled functions.
