如何解决您如何在Java中使用PerspectiveAPI？

如何使用perspective api，在Java中，我尝试了几种代码，但效果不太好。

我已经做到了，但是没有用。

`

try {
  String url = "https://commentanalyzer.googleapis.com/$discovery/rest?version=v1alpha1&",key = "key=my_key";

    final URL serverUrl = new URL(url + key);
        URLConnection urlConnection = serverUrl.openConnection();
        HttpURLConnection httpconnection = (HttpURLConnection)urlConnection;
        httpconnection.setRequestMethod("POST");
        httpconnection.setRequestProperty("Content-Type","application/json");
        httpconnection.setDoOutput(true);
        BufferedWriter httpRequestBodyWriter = new BufferedWriter(new
                OutputStreamWriter(httpconnection.getoutputStream()));
        httpRequestBodyWriter.write("{\"comment\": {\"text\": \"" + "Salut mec" + "\"},"
                + "\"requestedAttributes\": {\"TOXICITY\": {}}}");
        httpRequestBodyWriter.flush();
        httpRequestBodyWriter.close();
        System.out.println("CODE : " + httpconnection.getResponseCode());
        
        BufferedReader responseBuffer = new BufferedReader(new InputStreamReader((httpconnection.getInputStream())));
        String output;
        while ((output = responseBuffer.readLine()) != null) {
           System.out.println(output);
        }
        httpconnection.disconnect();
    } catch (IOException e1) {
        e1.printstacktrace();
    }`

我有代码404和Caused by: java.io.FileNotFoundException: https://commentanalyzer.googleapis.com/$discovery/rest?version=v1alpha1&key=my_key

你有个主意吗？
