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的 azure 网站一个>
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"
}
}
