存储Azure函数的环境变量的最佳位置 [英] Best place to store environment variables for Azure Function

问题描述

我正在用几个api键在本地测试azure函数.什么是存储环境变量的最佳位置，我如何访问它们?我尝试过

I'm testing an azure function locally with several api keys. Whats the best place to store environment variables and how do I access them? I tried

System.Environment.GetEnvironmentVariable("name")}

但我不确定环境变量的存储位置.

but I'm not sure where the environment variable is stored.

谢谢！

推荐答案

您应该有一个名为local.settings.json的文件.这是 Functions-Run-Local

You should have a file called local.settings.json. Here is the azure website for Functions-Run-Local

状态

这些设置也可以在您的代码中作为环境变量读取.在C#中，使用System.Environment.GetEnvironmentVariable或ConfigurationManager.AppSettings.在JavaScript中，使用process.env.指定为系统环境变量的设置优先于local.settings.json文件中的值.

These settings can also be read in your code as environment variables. In C#, use System.Environment.GetEnvironmentVariable or ConfigurationManager.AppSettings. In JavaScript, use process.env. Settings specified as a system environment variable take precedence over values in the local.settings.json file.

示例local.settings.json

example local.settings.json

{
  "IsEncrypted": false,   
  "Values": {
    "AzureWebJobsStorage": "<connection string>", 
    "AzureWebJobsDashboard": "<connection string>" 
  },
  "Host": {
    "LocalHttpPort": 7071, 
    "CORS": "*" 
  },
  "ConnectionStrings": {
    "SQLConnectionString": "Value"
  }
}

它表示您需要将应用程序设置放在local.settings.json中的 Values 属性下.

It says that you need to put the application settings under the Values property within the local.settings.json.

要进行检索，我使用了ConfigurationManager.AppSettings["CustomSetting"]，因为它可以检索连接字符串.

To retrieve I used ConfigurationManager.AppSettings["CustomSetting"] as it lets you retrieve connection strings.

我一直在玩这个游戏，发现您必须有一个字符串键和一个字符串值.尝试包含小节时出现错误(就像在appsettings.json中一样).我必须使local.settings.json看起来像这样:

I have just been playing around with this and discovered that you have to have a a string key and a string value. I got an error when I tried having a subsection (like you would in an appsettings.json). I had to have the local.settings.json look like this:

{
  "IsEncrypted": false,   
  "Values": {
    "AzureWebJobsStorage": "<connection string>", 
    "AzureWebJobsDashboard": "<connection string>" 
    "CustomSetting":"20"
  }
}
