如何在本地覆盖我的 azure 函数的主机设置? [英] How can I override the host settings of my azure function locally?

问题描述

假设你有一个这样的 host.json 文件:

Say you have a host.json file like this:

{
  "version": "2.0",
  "extensions": {
    "serviceBus": {
      "messageHandlerOptions": {
        "maxConcurrentCalls": 16,
        "maxAutoRenewDuration": "00:05:00"
      }
    }
  }
}

但您希望在本地覆盖 local.settings.json 或 Azure 上给定环境的设置中的设置.有可能吗，你是怎么做到的?

But you wish to override the setting locally in local.settings.json or in the settings for a given environment on Azure. Is it possible, and how do you do it?

推荐答案

这是可能的，但文档很少.Fabio Cavalcante 在评论中描述了它 这里.

It is possible, but poorly documented. Fabio Cavalcante describes it in a comment here.

您只需在 local.settings.json 文件(或在 Azure 上)中为设置添加 AzureFunctionsJobHost 前缀，如下所示:

You simply have to prefix the setting with AzureFunctionsJobHost in your local.settings.json file (or on Azure) like this:

{
  "IsEncrypted": false,
  "Values": {
    "AzureFunctionsJobHost:Extensions:ServiceBus:MessageHandlerOptions:MaxConcurrentCalls": 32,
    "AzureFunctionsJobHost:Extensions:ServiceBus:MessageHandlerOptions:MaxAutoRenewDuration": "00:10:00"
  }
}

您也可以使用双下划线 (__) 代替冒号 (:).

You can also use double underscore (__) instead of colon (:).
