<p>简单来说,配置将系统应用可动态调配的选项放在统一地方管理,通过不同的配置让系统做出动态调整。</p>
|
|
|
|
|
<p>在 <code>ASP.NET Core</code> 应用程序启动时默认加载 <code>启动项目</code> 下的 <code>appsettings.json</code> 作为应用配置。同时还支持<strong>不同的运行环境</strong>加载对应的配置文件,如:</p>
|
|
|
|
|
<ul>
|
|
|
|
|
<li><code>Development</code>:加载 <code>appsettings.Development.json</code></li>
|
|
|
|
|
<li><code>Staging</code>:加载 <code>appsettings.Staging.json</code></li>
|
|
|
|
|
<li><code>{Environment}</code>:<code>appsettings.{Environment}.json</code></li>
|
|
|
|
|
</ul>

|
|
|
|
|
<p>假设我们需要在系统运行时获取<strong>系统名称、版本号及版权信息</strong>,这些信息可能随时变化而且需要在多个地方使用。这时就需要将这些信息配置起来。具体步骤如下:</p>
