#鸿蒙通关秘籍#我在搞个应用，想自定义一下UserAgent，ArkWeb能帮我这个忙吗？

import { webview } from '@kit.ArkWeb';
@Entry
@Component
struct WebComponent {
controller: webview.WebviewController = new webview.WebviewController();
@State customUserAgent: string = ' DemoApp';
build() {
Column() {
Web({ src: 'www.example.com', controller: this.controller })
.onControllerAttached(() => {
try {
let userAgent = this.controller.getUserAgent() + this.customUserAgent;
this.controller.setCustomUserAgent(userAgent);
} catch (error) {
console.error(`ErrorCode: ${(error as BusinessError).code}, Message: ${(error as BusinessError).message}`);
}
})
}
}
