+# web子系统ChangeLog
+
+OpenHarmony 4.0.7.3 版本相较于OpenHarmony 之前的版本，web的API变更如下。
+
+## cl.web.1 setResponseData接口参数新增
+
+**变更影响**
+
+setResponseData(data: string | number | Resource)，新增入参类型`Resource`
+
+在应用hap不解压场景，应用hap中的文件路径已不存在。当需要读取hap包内资源时，通过使用入参`data:Resource`替代`data:number`，实现对本应用下的资源访问。
+
+
+**关键的接口/组件变更**
+
+- 涉及接口
+
+  setResponseData
+
+- 变更前：
+
+  ```ts
+  setResponseData(data: string | number)
+  ```
+
+- 变更后：
+
+  ```ts
+  setResponseData(data: string | number | Resource)
+  ```
+
+**适配指导**
+
+应用hap解压时，打开并持有资源文件fd，最后通过`setResponseData(data:number)`将资源响应数据传递给内核。
+
+```ts
+// xxx.ets
+import web_webview from '@ohos.web.webview'
+import fileio from '@ohos.fileio';
+
+@Entry
+@Component
+struct WebComponent {
+  controller: web_webview.WebviewController = new web_webview.WebviewController()
+  responseweb: WebResourceResponse = new WebResourceResponse()
+  heads: Header[] = new Array()
+
+  build() {
+    Column() {
+      Web({ src: 'www.example.com', controller: this.controller })
+        .onInterceptRequest((event) => {
+          console.log('url:' + event.request.getRequestUrl())
+          var head1:Header = {
+            headerKey:"Connection",
+            headerValue:"keep-alive"
+          }
+          var head2:Header = {
+            headerKey:"Cache-Control",
+            headerValue:"no-cache"
+          }
+          var length = this.heads.push(head1)
+          length = this.heads.push(head2)
+          this.responseweb.setResponseHeader(this.heads)
+          this.responseweb.setResponseEncoding('utf-8')
+          this.responseweb.setResponseMimeType('text/html')
+          this.responseweb.setResponseCode(200)
+          this.responseweb.setReasonMessage('OK')
+
+          //// fd方案 --start
+          // '/xxx/.../test.html'为文件的本地路径
+          // @ts-ignore
+          let fd = fileio.openSync('/xxx/.../test.html', 0o102, 0o666)
+          this.responseweb.setResponseData(fd)
+          //// fd方案 --end
