所以我编写了一个在本地工作得很好的 azure 函数。我相信这取决于 local.setting.json
文件。但是当我将其发布到 azure 时,该函数不起作用,因为它找不到我定义的设置值。来自网络应用程序和控制台驱动的方法,我们将拥有与每个环境关联的不同配置文件。我怎样才能让它工作,这样我就可以拥有多个 settings.json
文件,例如一个用于开发、雄鹿和生产环境?最终结果是使用 octopus 部署来部署它,但在这一点上,如果我什至无法让它与发布一起工作,那么就没有机会这样做。
我很困惑为什么这些信息不容易获得,因为我认为这是常见的事情?
最佳答案
我希望看到函数以与 ASP.NET Core 或控制台应用程序相同的方式支持环境特定设置。与此同时,我正在使用下面的代码,这有点hacky(请参阅评论)。
public class Startup : FunctionsStartup
{
public override void Configure(IFunctionsHostBuilder builder)
{
// Get the path to the folder that has appsettings.json and other files.
// Note that there is a better way to get this path: ExecutionContext.FunctionAppDirectory when running inside a function. But we don't have access to the ExecutionContext here.
// Functions team should improve this in future. It will hopefully expose FunctionAppDirectory through some other way or env variable.
string basePath = IsDevelopmentEnvironment() ?
Environment.GetEnvironmentVariable("AzureWebJobsScriptRoot") :
$"{Environment.GetEnvironmentVariable("HOME")}\\site\\wwwroot";
var config = new ConfigurationBuilder()
.SetBasePath(basePath)
.AddJsonFile("appsettings.json", optional: false, reloadOnChange: false) // common settings go here.
.AddJsonFile($"appsettings.{Environment.GetEnvironmentVariable("AZURE_FUNCTIONS_ENVIRONMENT")}.json", optional: false, reloadOnChange: false) // environment specific settings go here
.AddJsonFile("local.settings.json", optional: true, reloadOnChange: false) // secrets go here. This file is excluded from source control.
.AddEnvironmentVariables()
.Build();
builder.Services.AddSingleton<IConfiguration>(config);
}
public bool IsDevelopmentEnvironment()
{
return "Development".Equals(Environment.GetEnvironmentVariable("AZURE_FUNCTIONS_ENVIRONMENT"), StringComparison.OrdinalIgnoreCase);
}
}
