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...
}
