从 VS 2017 Azure Function 开发中的 local.settings.json 读取值 [英] Read values from local.settings.json in VS 2017 Azure Function development

问题描述

我正在 VS 2017 中编写 Azure 函数.我需要设置一些自定义配置参数.我在 Values 下的 local.settings.json 中添加了它们.

I am writing an Azure function in VS 2017. I need to set up a few custom configuration parameters. I added them in local.settings.json under Values.

{
   "IsEncrypted":false,
   "Values" : {
      "CustomUrl" : "www.google.com",
       "Keys": { 
           "Value1":"1",
           "Value2" :"2"
       }
   }
}

现在，ConfigurationManager.AppSettings["CustomUrl"] 返回 null.

Now, ConfigurationManager.AppSettings["CustomUrl"] returns null.

我正在使用:

• .NET 框架 4.7
• Microsoft.NET.Sdk.Functions 1.0.5
• System.Configuration.ConfigurationManager 4.4.0
• Azure.Functions.Cli 1.0.4

我错过了什么吗?

推荐答案

首先，我创建了一个示例并使用您的 local.settings.json 数据进行测试，正如 Mikhail 和 ahmelsayed 所说，它工作正常.

Firstly, I create a sample and do a test with your local.settings.json data, as Mikhail and ahmelsayed said, it works fine.

此外，据我所知，Values 集合应该是一个字典，如果它包含任何非字符串值，可能会导致 Azure 函数无法从 local.settings 中读取值.json.

Besides, as far as I know, Values collection is expected to be a Dictionary, if it contains any non-string values, it can cause Azure function can not read values from local.settings.json.

我的测试:

ConfigurationManager.AppSettings["CustomUrl"] 使用以下 local.settings.json 返回 null.

ConfigurationManager.AppSettings["CustomUrl"] returns null with the following local.settings.json.

{
  "IsEncrypted": false,
  "Values": {
    "CustomUrl": "www.google.com",
    "testkey": {
      "name": "kname1",
      "value": "kval1"
    }
  }
}
