&lt;h4 class="alert-heading">注意&lt;/h4>

 认证流程仅适用于内置组件，不适用于&lt;a href="https://v1-18.docs.dapr.io/zh-hans/concepts/components-concept/#Built-in-and-pluggable-components">可插拔组件&lt;/a>。

&lt;/div>

&lt;h2 id="概述">概述&lt;/h2>
&lt;p>Dapr 采用模块化设计，功能以组件形式提供。每个组件都有一个接口定义，所有组件都是可互换的，因此理想情况下，您可以用具有相同接口的另一个组件替换一个组件。每个用于生产的组件都需要满足一定的技术要求，以确保功能兼容性和稳健性。&lt;/p>
&lt;p>一般来说，一个组件需要：&lt;/p>
&lt;ul>
&lt;li>符合定义的 Dapr 接口&lt;/li>
&lt;li>功能正确且稳健&lt;/li>
&lt;li>有良好的文档和维护&lt;/li>
&lt;/ul>
&lt;p>为了确保组件符合 Dapr 设定的标准，会在 Dapr 维护者管理的环境中对组件进行一系列测试。一旦测试持续通过，就可以确定组件的成熟度级别。&lt;/p>
&lt;h2 id="认证级别">认证级别&lt;/h2>
&lt;p>级别如下：&lt;/p>
&lt;ul>
&lt;li>&lt;a href="https://v1-18.docs.dapr.io/zh-hans/operations/components/certification-lifecycle/#alpha">Alpha&lt;/a>&lt;/li>
&lt;li>&lt;a href="https://v1-18.docs.dapr.io/zh-hans/operations/components/certification-lifecycle/#beta">Beta&lt;/a>&lt;/li>
&lt;li>&lt;a href="https://v1-18.docs.dapr.io/zh-hans/operations/components/certification-lifecycle/#stable">Stable&lt;/a>&lt;/li>
&lt;/ul>
&lt;h3 id="alpha">Alpha&lt;/h3>
&lt;ul>
&lt;li>组件实现了所需的接口，并按规范描述工作&lt;/li>
&lt;li>组件有文档&lt;/li>
&lt;li>组件可能存在漏洞，或在集成时暴露出漏洞&lt;/li>
&lt;li>组件可能无法通过所有一致性测试&lt;/li>
&lt;li>组件可能没有一致性测试&lt;/li>
&lt;li>由于后续版本中可能出现不兼容的更改，仅推荐用于非关键业务用途&lt;/li>
&lt;/ul>
&lt;p>所有组件都从 Alpha 阶段开始。&lt;/p>
&lt;h3 id="beta">Beta&lt;/h3>
&lt;ul>
&lt;li>组件必须通过所有定义的组件一致性测试以满足组件规范&lt;/li>
&lt;li>组件一致性测试已在 Dapr 维护者管理的环境中运行&lt;/li>
&lt;li>组件包含由 Dapr 维护者审核和批准的特定 components-contrib 版本的一致性测试结果记录&lt;/li>
&lt;li>由于后续版本中可能出现不兼容的更改，仅推荐用于非关键业务用途&lt;/li>
&lt;/ul>


&lt;div class="alert alert-primary" role="alert">
&lt;h4 class="alert-heading">注意&lt;/h4>

 &lt;p>如果满足以下条件，组件可以跳过 Beta 阶段和一致性测试要求，由维护者决定：&lt;/p>
&lt;ul>
&lt;li>组件是一个绑定&lt;/li>
&lt;li>认证测试是全面的&lt;/li>
&lt;/ul>

&lt;/div>

&lt;h3 id="stable">Stable&lt;/h3>
&lt;ul>
&lt;li>组件必须有组件&lt;a href="https://v1-18.docs.dapr.io/zh-hans/operations/components/certification-lifecycle/#certification-tests">认证测试&lt;/a>以验证功能和弹性&lt;/li>
&lt;li>组件由 Dapr 维护者维护并由社区支持&lt;/li>
&lt;li>组件有良好的文档和测试&lt;/li>
&lt;li>组件在之前至少一个 Dapr 运行时的小版本发布中以 Alpha 或 Beta 形式存在&lt;/li>
&lt;li>维护者将根据 Dapr 支持政策解决组件安全性、核心功能和测试问题，并发布包含修补的稳定组件的补丁版本&lt;/li>
&lt;/ul>


&lt;div class="alert alert-primary" role="alert">
&lt;h4 class="alert-heading">注意&lt;/h4>

 &lt;p>稳定的 Dapr 组件基于 Dapr 认证和一致性测试，并不保证由任何特定供应商支持，其中供应商的 SDK 作为组件的一部分使用。&lt;/p></description></item><item><title>更新组件</title><link>https://v1-18.docs.dapr.io/zh-hans/operations/components/component-updates/</link><pubDate>Mon, 01 Jan 0001 00:00:00 +0000</pubDate><guid>https://v1-18.docs.dapr.io/zh-hans/operations/components/component-updates/</guid><description>&lt;p>在更新应用程序使用的现有已部署组件时，除非启用了 &lt;a href="https://v1-18.docs.dapr.io/zh-hans/operations/components/component-updates/#hot-reloading-preview-feature">&lt;code>HotReload&lt;/code>&lt;/a> 功能门控，否则 Dapr 不会自动更新组件。需要重启 Dapr sidecar 才能获取组件的最新版本。具体操作方式取决于托管环境。&lt;/p>
&lt;h3 id="kubernetes">Kubernetes&lt;/h3>
&lt;p>在 Kubernetes 中运行时，更新组件的过程包括以下两个步骤：&lt;/p>
&lt;ol>
&lt;li>将新的组件 YAML 应用到所需的命名空间。&lt;/li>
&lt;li>除非启用了 &lt;a href="https://v1-18.docs.dapr.io/zh-hans/operations/components/component-updates/#hot-reloading-preview-feature">&lt;code>HotReload&lt;/code> 功能门控&lt;/a>，否则需要对部署执行 &lt;a href="https://kubernetes.io/docs/reference/kubectl/cheatsheet/#updating-resources">滚动重启操作&lt;/a> 以获取最新组件。&lt;/li>
&lt;/ol>
&lt;h3 id="自托管">自托管&lt;/h3>
&lt;p>除非启用了 &lt;a href="https://v1-18.docs.dapr.io/zh-hans/operations/components/component-updates/#hot-reloading-preview-feature">&lt;code>HotReload&lt;/code> 功能门控&lt;/a>，更新组件的过程包括停止和重启 &lt;code>daprd&lt;/code> 进程以获取最新组件的单个步骤。&lt;/p>
&lt;h2 id="热重载预览功能">热重载（预览功能）&lt;/h2>
&lt;blockquote>
&lt;p>此功能目前处于&lt;a href="https://v1-18.docs.dapr.io/zh-hans/operations/configuration/preview-features/">预览&lt;/a>状态。
热重载通过 &lt;a href="https://v1-18.docs.dapr.io/zh-hans/operations/support/support-preview-features/">&lt;code>HotReload&lt;/code> 功能门控&lt;/a> 启用。&lt;/p>&lt;/blockquote>
&lt;p>Dapr 可以实现“热重载”组件，从而在不需要重启 Dapr sidecar 进程或 Kubernetes pod 的情况下自动获取组件更新。这意味着创建、更新或删除组件清单将在运行时反映在 Dapr sidecar 中。&lt;/p>


&lt;div class="alert alert-warning" role="alert">
&lt;h4 class="alert-heading">更新组件&lt;/h4>

 当组件更新时，它首先被关闭，然后使用新配置重新初始化。这会导致组件在此过程中短时间内不可用。

&lt;/div>



&lt;div class="alert alert-warning" role="alert">
&lt;h4 class="alert-heading">初始化错误&lt;/h4>

 &lt;p>如果通过热重载创建或更新组件时初始化过程出错，Dapr sidecar 会遵循组件字段 &lt;a href="https://v1-18.docs.dapr.io/zh-hans/reference/resource-specs/component-schema/">&lt;code>spec.ignoreErrors&lt;/code>&lt;/a> 的设置。也就是说，行为与 sidecar 在启动时加载组件时相同。&lt;/p>
&lt;ul>
&lt;li>&lt;code>spec.ignoreErrors=false&lt;/code> (&lt;em>默认&lt;/em>): sidecar 优雅地关闭。&lt;/li>
&lt;li>&lt;code>spec.ignoreErrors=true&lt;/code>: sidecar 继续运行，既没有注册旧的也没有注册新的组件配置。&lt;/li>
&lt;/ul>

&lt;/div>

&lt;p>除以下类型外，所有组件均支持热重载。这些组件类型的任何创建、更新或删除都将被 sidecar 忽略，需要重启以获取更改。&lt;/p>

&lt;p>Dapr运行时，会将其配置的命名空间与加载的组件的命名空间进行匹配，并仅初始化与其命名空间匹配的组件。其他命名空间中的组件将不会被加载。&lt;/p>
&lt;h2 id="命名空间">命名空间&lt;/h2>
&lt;p>命名空间可以用来限制组件对特定Dapr实例的访问。&lt;/p>

 &lt;p>在自托管模式下，开发者可以通过设置&lt;code>NAMESPACE&lt;/code>环境变量来为Dapr实例指定命名空间。

&lt;p>在组件定义的&lt;code>spec.metadata&lt;/code>部分中，可以引用secret。&lt;/p>
&lt;p>要引用secret，你需要设置&lt;code>auth.secretStore&lt;/code>字段来指定保存secret的secret存储的名称。&lt;/p>
&lt;p>在Kubernetes中运行时，如果&lt;code>auth.secretStore&lt;/code>为空，则默认使用Kubernetes secret存储。&lt;/p>

&lt;p>虽然你可以选择使用纯文本secret（如MyPassword），如下面yaml中&lt;code>redisPassword&lt;/code>的&lt;code>value&lt;/code>所示，但这不建议用于生产环境：&lt;/p>

&lt;p>在 Dapr 中，Secret 存储通过一个 &lt;code>Component&lt;/code> 文件进行描述，包含以下字段：&lt;/p>

&lt;p>&lt;a href="https://v1-18.docs.dapr.io/zh-hans/developing-applications/develop-components/pluggable-components/pluggable-components-overview/">使用 gRPC 的可插拔组件&lt;/a>通常作为容器或进程运行，需要通过&lt;a href="https://en.wikipedia.org/wiki/Unix_domain_socket">Unix 域套接字&lt;/a>（简称 UDS）与 Dapr 运行时通信。它们会通过以下步骤自动被发现并注册到运行时中：&lt;/p>
&lt;ol>
&lt;li>组件监听放置在共享卷上的&lt;a href="https://en.wikipedia.org/wiki/Unix_domain_socket">Unix 域套接字&lt;/a>。&lt;/li>
&lt;li>Dapr 运行时列出共享卷中的所有&lt;a href="https://en.wikipedia.org/wiki/Unix_domain_socket">Unix 域套接字&lt;/a>。&lt;/li>
&lt;li>Dapr 运行时连接每个套接字，并使用 gRPC 反射从组件实现的给定构建块 API 中发现所有 proto 服务。&lt;/li>
&lt;/ol>
&lt;p>一个组件可以同时实现多个组件接口。&lt;/p>
&lt;img src="https://v1-18.docs.dapr.io/images/components-pluggable-register-grpc.png" width=50%>
&lt;p>虽然 Dapr 的内置组件已经集成在运行时中，但可插拔组件在与 Dapr 一起使用之前需要进行一些设置步骤。&lt;/p>
&lt;ol>
&lt;li>可插拔组件需要在 Dapr 本身启动之前启动并准备好接收请求。&lt;/li>
&lt;li>用于可插拔组件通信的&lt;a href="https://en.wikipedia.org/wiki/Unix_domain_socket">Unix 域套接字&lt;/a>文件需要对 Dapr 和可插拔组件都可访问。&lt;/li>
&lt;/ol>
&lt;p>在独立模式下，可插拔组件可以作为进程或容器运行。在 Kubernetes 上，可插拔组件作为容器运行，并由 Dapr 的 sidecar 注入器自动注入到应用程序的 pod 中，允许通过标准的&lt;a href="https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.25/#container-v1-core">Kubernetes 容器规范&lt;/a>进行自定义。&lt;/p>
&lt;p>这也改变了在 Dapr 和可插拔组件之间共享&lt;a href="https://en.wikipedia.org/wiki/Unix_domain_socket">Unix 域套接字&lt;/a>文件的方法。&lt;/p>


&lt;div class="alert alert-primary" role="alert">
&lt;h4 class="alert-heading">注意&lt;/h4>

 作为前提条件，操作系统必须支持 Unix 域套接字，任何 UNIX 或类 UNIX 系统（Mac、Linux 或用于本地开发的 &lt;a href="https://learn.microsoft.com/windows/wsl/install">WSL&lt;/a> 对于 Windows 用户）都应该足够。

&lt;/div>

&lt;ol>
&lt;li>基础模块 API - 在调用任何 Dapr HTTP API 时执行 HTTP 中间件组件。&lt;/li>
&lt;li>服务间调用 - HTTP 中间件组件应用于服务间调用。&lt;/li>
&lt;/ol>
&lt;h2 id="配置-api-中间件管道">配置 API 中间件管道&lt;/h2>
&lt;p>启动时，Dapr sidecar 会为传入的 HTTP 调用构建一个中间件处理管道。默认情况下，管道由&lt;a href="https://v1-18.docs.dapr.io/zh-hans/operations/observability/tracing/tracing-overview/">追踪&lt;/a>和 CORS 中间件组成。可以通过 Dapr &lt;a href="https://v1-18.docs.dapr.io/zh-hans/concepts/configuration-concept/">configuration&lt;/a> 配置的其他中间件按定义顺序添加到管道中。该管道适用于所有 Dapr API 端点，包括 state、pubsub、service-invocation、bindings、secret、configuration、分布式锁等。&lt;/p>
&lt;p>请求在路由到用户代码之前会依次经过所有定义的中间件组件，然后在返回给客户端之前以相反的顺序再次经过这些中间件，如下图所示。&lt;/p>
&lt;img src="https://v1-18.docs.dapr.io/images/middleware.png" width="800" alt="图示请求和响应通过中间件的流程，如上段所述" />
&lt;p>在使用 &lt;code>httpPipeline&lt;/code> 配置调用 Dapr HTTP API 时，HTTP 中间件组件会被执行。&lt;/p>
&lt;p>以下配置示例定义了一个自定义管道，使用了 &lt;a href="https://v1-18.docs.dapr.io/zh-hans/reference/components-reference/supported-middleware/middleware-oauth2/">OAuth 2.0 中间件&lt;/a> 和 &lt;a href="https://v1-18.docs.dapr.io/zh-hans/reference/components-reference/supported-middleware/middleware-uppercase/">大写中间件组件&lt;/a>。在这种情况下，所有请求在转发到用户代码之前都通过 OAuth 2.0 协议进行授权，并转换为大写文本。&lt;/p>
