HarmonyOS 集群环境设置webview的cookie

推荐使用以下方法：

方法一：循环遍历 方法二：字符串配置

demo如下：

import { BusinessError } from '@kit.BasicServicesKit';
import { webview } from '@kit.ArkWeb';

@Entry
@Component
struct WebComponent {
  controller: webview.WebviewController = new webview.WebviewController();
  testCookie: string = "myTestCookie=123,path=/";

  aboutToAppear(): void {
    // 方法一：循环遍历
    webview.WebCookieManager.configCookieSync('https://www.index.com', '123=123');
    webview.WebCookieManager.configCookieSync('https://www.index.com', '456=456');
    //方法二：字符串配置
    webview.WebCookieManager.configCookieSync('https://www.index.com', this.testCookie)
  }

  build() {
    Column() {
      Button('fetchCookieSync')
        .onClick(() => {
          try {
            let value = webview.WebCookieManager.fetchCookieSync('https://www.index.com');
            console.log("fetchCookieSync cookie = " + value);
          } catch (error) {
            console.error(`ErrorCode: ${(error as BusinessError).code}, Message: ${(error as BusinessError).message}`);
          }
        })
      Web({ controller: this.controller, src: 'https://www.index.com' }).onControllerAttached(() => {
        let ua = this.controller.getUserAgent()
        this.controller.setCustomUserAgent(ua)
      })
    }
  }
}
