HarmonyOS 快速搭建案例

webview用来承载H5页面。可参考web组件，demo如下：

import web_webview from '@ohos.web.webview'
@Entry
@Component
struct WebComponent {
  controller: web_webview.WebviewController = new web_webview.WebviewController();
  @State customUserAgent: string = 'test'
  build() {
    Column() {
      Web({ src: 'xxx', controller: this.controller })
        .onControllerAttached(() => {
          //常用手机的UserAgent列表
          let userAgent = "Mozilla/5.0 (Linux; xxx 7.1.1; OPPO R11st Build/NMF26X; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/63.0.3239.83 Mobile Safari/537.36 T7/11.15 examplesboxapp/11.15.5.10 (examples; P1 7.1.1)"
          //设置自定义UA
          this.controller.setCustomUserAgent(userAgent);
          //获取自定义UA
          console.log("userAgent: " + this.controller.getCustomUserAgent());
        })
    }
  }
}
