&lt;p>Wasm &lt;a href="https://v1-18.docs.dapr.io/zh-hans/operations/components/middleware/">HTTP中间件&lt;/a>允许您使用编译为Wasm二进制文件的自定义逻辑来处理传入请求或提供响应。换句话说，您可以使用未预编译到&lt;code>daprd&lt;/code>二进制文件中的外部文件来扩展Dapr。Dapr嵌入了&lt;a href="https://wazero.io">wazero&lt;/a>以在不使用CGO的情况下实现这一点。&lt;/p>
&lt;p>Wasm二进制文件可以从URL加载。例如，使用URL &lt;code>file://rewrite.wasm&lt;/code>可以从进程的当前目录加载&lt;code>rewrite.wasm&lt;/code>文件。在Kubernetes环境中，您可以参考&lt;a href="https://v1-18.docs.dapr.io/zh-hans/operations/hosting/kubernetes/kubernetes-volume-mounts/">如何：将Pod卷挂载到Dapr sidecar&lt;/a>来配置可以包含Wasm模块的文件系统挂载。也可以从远程URL获取Wasm二进制文件。在这种情况下，URL必须精确指向一个Wasm二进制文件。例如：&lt;/p>
&lt;ul>
&lt;li>&lt;code>http://example.com/rewrite.wasm&lt;/code>，或&lt;/li>
&lt;li>&lt;code>https://example.com/rewrite.wasm&lt;/code>。&lt;/li>
