存储 Azure Function 环境变量的最佳位置

Best place to store environment variables for Azure Function(存储 Azure Function 环境变量的最佳位置)

问题描述

我正在使用几个 api 键在本地测试一个 azure 函数.存储环境变量的最佳位置是什么以及如何访问它们?我试过了

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

你应该有一个名为 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

说明

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.

local.settings.json 示例

example local.settings.json

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

它说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.

为了检索，我使用了 ConfigurationManager.AppSettings["CustomSetting"]，因为它可以让您检索连接字符串.

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

我一直在玩这个，发现你必须有一个字符串键和一个字符串值.当我尝试创建一个小节时出现错误(就像您在 appsettings.json 中所做的那样).我必须让 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"
  }
}
