Question

在webview中加载某些页面时，我几次收到WebView中显示的请求标题或会话Cookie太大这个异常。

在WebView中加载URL的方式：

webView = (WebView) findViewById(R.id.idWebView);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient());

Map<String, String> headers = new HashMap<>();
headers.put("Accept-Language", getLanguage());
webView.loadUrl(url, headers);

为了清楚起见，即使没有 headers.put（“Accept-Language”，getLanguage（）），也会发生这种情况;

我不确定这是否应该在Android或服务器端修复。有没有人在Android WebViews上遇到过类似的问题？

这是此例外的控制台日志：

<强>解决方案

我将以下代码添加到我的自定义WebView中（您可以将其添加到任何您想要的位置）。

private void clearCookies() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
        CookieManager.getInstance().removeAllCookies(null);
        CookieManager.getInstance().flush();
        return;
    }

    CookieSyncManager cookieSyncManager = CookieSyncManager.createInstance(getContext());
    cookieSyncManager.startSync();
    CookieManager cookieManager = CookieManager.getInstance();
    cookieManager.removeAllCookie();
    cookieManager.removeSessionCookie();
    cookieSyncManager.stopSync();
    cookieSyncManager.sync();
}

因此，在加载任何网址之前，我只需拨打 clearCookies（）
