我有一个WebView,我想从另一个类获取此WebView的链接。 我的另一个类从JSON数据获取此链接。你能帮我吗?我是Java新手:/
Main.java;
btn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
engine.load("https://www.google.com");
}
});
Reader.java(链接在这里)
public class Readerr {
private static String readAll(Reader rd) throws IOException {
StringBuilder sb = new StringBuilder();
int cp;
while ((cp = rd.read()) != -1) {
sb.append((char) cp);
}
return sb.toString();
}
public static JSONObject readJsonFromUrl(String url) throws IOException, JSONException {
InputStream is = new URL(url).openStream();
try {
BufferedReader rd = new BufferedReader(new InputStreamReader(is, Charset.forName("UTF-8")));
String jsonText = readAll(rd);
JSONObject json = new JSONObject(jsonText);
return json;
} finally {
is.close();
}
}
public static void main(String[] args) throws IOException, JSONException {
JSONObject json = readJsonFromUrl("https://api.myjson.com/bins/cs3x6");
String Link = json.get("link").toString();
}
}
