In official documentation of Google Translate Api for Java it says that we can use post-method to send more than 2K characters. https://developers.google.com/translate/v2/using_rest
However when I try to translate text more than 2k length I get error 414 (Request-URI Too Large).
StringBuilder sb = new StringBuilder();
HttpURLConnection connection = null;
try {
URL url = new URL("https://www.googleapis.com/language/translate/v2");
String urlParameters = "key=" + apiKey + "&source=" + shortLang1 +
"&target=" + shortLang2 + "&q=" + URLEncoder.encode(lyrics, "UTF-8");
connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches (false);
connection.addRequestProperty("X-HTTP-Method-Override", "GET");
DataOutputStream wr = new DataOutputStream (connection.getOutputStream ());
wr.writeBytes (urlParameters);
wr.flush ();
wr.close ();
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8"));
if (connection.getResponseCode() != 200) {
return null;
}
String line;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
reader.close();
} catch (Exception e) {
e.printStackTrace();
} finally {
if (connection != null) {
connection.disconnect();
}
}
UPDATE: I got it, the code above is right. Finally I realize that I got this error not from Google Translate service but from my proxy on Google App Engine.
