如何在 WebView 中加载带有标题的 URL？

Question

我想在 WebView 中加载一个 URL 并添加标题User-Agent和autoToken. 我试图val map = HashMap<String, String>()将其添加为webview.loadUrl(url, map).

第二次尝试只是覆盖shouldInterceptRequest().

override fun shouldInterceptRequest(view: WebView?, request: WebResourceRequest): WebResourceResponse? {
    request.requestHeaders?.put(LegacyAuthInterceptor.HEADER_AUTH_TICKET, autoToken)
   request.requestHeaders?.put("User-Agent", userAgent)
    return super.shouldInterceptRequest(view, request)
  }

这些解决方案都不起作用。

Answer 1

使用以下进行更改User-Agent

webview.getSettings().setUserAgentString("userAgent");

理想情况下webview.loadUrl(url, map)添加标题就足够了。在另一个替代方案中，重写了以下方法WebViewClient：

@Override
@TargetApi(Build.VERSION_CODES.LOLLIPOP)
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request){
    view.loadUrl(request.getUrl().toString(),headerMap);
    return true;
}

@Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
    view.loadUrl(url,headerMap);
    return true;
}

Answer 2

val map = HashMap<String, String>()
map[AUTO_TOKEN] = autoToken
webClientBinding.webView.settings.userAgentString = userAgent
WebView.setWebContentsDebuggingEnabled(true)
webClientBinding.webView.webViewClient = object : WebViewClient() {
  override fun shouldInterceptRequest(view: WebView?, request: WebResourceRequest): WebResourceResponse? {
    CookieManager.getInstance().removeAllCookies(null)
    return super.shouldInterceptRequest(view, request)
  }
}
webClientBinding.webView.loadUrl(url, map)

它应该有效！
