我正在WebView中加载URL，并在登录后返回响应。我想获得该回复并使用该值。
WebView的代码
final WebView wb = (WebView) findViewById(R.id.wb1);
WebViewClient yourWebClient = new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
@Override
public void onPageFinished(WebView view, String url) {
wb.loadUrl("javascript:HtmlViewer.showHTML" +
"(document.getElementsByTagName('html')[0].innerHTML);");
}
};
wb.getSettings().setJavaScriptEnabled(true);
wb.getSettings().setSupportZoom(true);
wb.getSettings().setBuiltInZoomControls(true);
wb.setWebViewClient(yourWebClient);
wb.loadUrl(url);
wb.addJavascriptInterface(new MyJavaScriptInterface(this), "HtmlViewer");
}
class MyJavaScriptInterface {
private Context ctx;
MyJavaScriptInterface(Context ctx) {
this.ctx = ctx;
}
@JavascriptInterface
public void showHTML(String html) {
Log.e("TAG", "showHTML: " + html);
Document document = Jsoup.parse(html);
Elements elements = document.select("pre");
for (Element element : elements) {
//Save As you want to
Log.d("TAG", " myHTMLResponseCallback : " + element.attr("connected_id"));
}
System.out.println(html);
}
}
我从服务器得到以下响应：
{"status":"success","connected_id":"eyuryriufgrg"}
当我将其获取为html时，我得到了：
<head></head><body><pre style="word-wrap: break-word; white-space: pre-wrap;">{"status":"success","connected_id":"eyuryriufgrg"}</pre></body>
如何获取“ connected_id”的值。
