Azure Function中的复杂对象应用程序设置

标签: c# azure .net-core azure-functions

我在local.settings.json中有这些条目

{
    "IsEncrypted": false,
    "Values": {
        "AzureWebJobsStorage": "whateverstorageaccountconnectionstring",
        "FUNCTIONS_WORKER_RUNTIME": "dotnet"
    },
    "BusinessUnitMapping": {
        "Values": {
            "Connections": "CON",
            "Products": "PRD",
            "Credit & Affordability": "CAA",
            "Accounts Receivable": "ARC",
            "Identity":  "IDT"
        }
    }
}

我有这段代码可以在启动时读取值

services.Configure<BusinessUnitMapping>(options => configuration.GetSection("BusinessUnitMapping").Bind(options));

其中BusinessUnitMapping为

public class BusinessUnitMapping
{
  public Dictionary<string, string> Values { get; set; }
  public BusinessUnitMapping()
  {
      Values = new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase);
  }
}

当我在本地运行功能应用程序时,它可以毫无问题地将这些设置读入BusinessUnitMapping。

Azure门户中的应用程序设置的高级编辑仅允许如下所示的简单键值对

[
  {
    "name": "AzureWebJobsDashboard",
    "value": "DefaultEndpointsProtocol=Somevalue",
    "slotSetting": false
  },
  {
    "name": "AzureWebJobsStorage",
    "value": "DefaultEndpointsProtocol=Somevalue",
    "slotSetting": false
  },
  ...
]

问题

  1. 这是将复杂的应用程序设置存储在Azure Function中的正确方法吗?
  2. 如何在Azure门户中为已部署的功能应用程序配置BusinessUnitMapping?

我当前的首选方法是将options pattern与使用GetEnvironmentVariable的委托一起使用,该委托将在本地和Azure中工作。缺点是您不能在本地设置文件本身中创建复杂的类型,但是您的对象可以任意复杂。

一个简单的例子:

在local.settings.json中:

{
  ...
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    ...
    "SomeSection:Setting1": "abc",
    "SomeSection:Setting2": "xyz",
  },
  ...
}

在您的创业公司:

services.Configure<MySettingsPoco>(o =>
{
    o.Setting1 = Environment.GetEnvironmentVariable("SomeSection:Setting1");
    o.Setting2 = Environment.GetEnvironmentVariable("SomeSection:Setting2");
});

然后在Azure中,您可以按照以下步骤创建这些设置:

1。这是将复杂应用程序设置存储在Azure Function中的正确方法吗?

我们可以将这些条目保存在应用设置中。有关更多详细信息,请参阅document。详细步骤如下。

2。如何在Azure门户中为已部署的功能应用程序配置BusinessUnitMapping?

根据我的测试,我们可以使用以下代码来实现

#r "Newtonsoft.Json"

using System.Net;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Primitives;
using Newtonsoft.Json;
using System.Collections.Generic;
public static async Task<IActionResult> Run(HttpRequest req, ILogger log)
{
    log.LogInformation("C# HTTP trigger function processed a request.");
    var test =Environment.GetEnvironmentVariable("test",EnvironmentVariableTarget.Process);
    log.LogInformation(test);
    var values= JsonConvert.DeserializeObject<Dictionary<string, string>>(test);
    var businessUnitMapping = new BusinessUnitMapping();
    businessUnitMapping.Values = values; 
    log.LogInformation(businessUnitMapping.Values["Products"]);
    string name = req.Query["name"];

    string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
    dynamic data = JsonConvert.DeserializeObject(requestBody);
    name = name ?? data?.name;

    return name != null
        ? (ActionResult)new OkObjectResult($"Hello, {name}")
        : new BadRequestObjectResult("Please pass a name on the query string or in the request body");
}

public class BusinessUnitMapping
    {
        public Dictionary<string, string> Values { get; set; }
        public BusinessUnitMapping()
        {

        }
    }
