javascript - 阻止 webview 发出定期请求

Question

我有一个 webview，它加载一个外部 javascript 移动应用程序，但该应用程序不是我的应用程序，因此我无法操作它。

这个 javascript 应用程序的问题:它不断调用某个 url。 在 WebViewClient.shouldInterceptRequest 方法中，我记录了调用的 url。 这是输出:

正如你所看到的。每 50 到 60 毫秒自动发出一个请求。我想知道如何阻止页面这样做？

有什么建议吗？

Answer 1

尝试覆盖shouldOverrideUrlLoading，如下所示:

public class MyWebClient extends WebViewClient {
    ...

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {

        if(url.startsWith("https://m.tipico.com/ajax/login/register")) {
            return true;
        }

        return false;
    }

   ...
}
