如何在 ConfigureServices 中获取开发/暂存/生产托管环境

问题描述

如何在 Startup 的 ConfigureServices 方法中获取 Development/Staging/production Hosting Environment?

How do I get the Development/Staging/production Hosting Environment in the ConfigureServices method in Startup?

public void ConfigureServices(IServiceCollection services)
{
    // Which environment are we running under?
}

ConfigureServices 方法只接受一个 IServiceCollection 参数.

The ConfigureServices method only takes a single IServiceCollection parameter.

推荐答案

在ConfigureServices中可以很方便的访问，只需在Startup方法中持久化到一个属性中，先调用并传入，然后就可以访问该属性了来自 ConfigureServices.

You can easily access it in ConfigureServices, just persist it to a property during Startup method which is called first and gets it passed in, then you can access the property from ConfigureServices.

public Startup(IWebHostEnvironment env, IApplicationEnvironment appEnv)
{
    ...your code here...
    CurrentEnvironment = env;
}

private IWebHostEnvironment CurrentEnvironment{ get; set; } 
 
public void ConfigureServices(IServiceCollection services)
{
    string envName = CurrentEnvironment.EnvironmentName;
    ... your code here...
}
