通过Java百度翻译API实现中文与葡萄牙语的即时翻译

try {
    // 对要翻译的文本进行URL编码
    String encodedText = URLEncoder.encode(text, "UTF-8");
    
    // 构建URL
    String urlStr = "http://api.fanyi.baidu.com/api/trans/vip/translate";
    urlStr += "?q=" + encodedText;
    urlStr += "&from=zh&to=pt";
    urlStr += "&appid=" + apiKey;
    urlStr += "&salt=1435660288";
    urlStr += "&sign=" + MD5.md5(apiKey + text + "1435660288" + "您的密钥");
    
    // 发送HTTP GET请求
    URL url = new URL(urlStr);
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    connection.setRequestMethod("GET");
    
    // 获取响应结果
    BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
    String line;
    StringBuilder response = new StringBuilder();
    while ((line = reader.readLine()) != null) {
        response.append(line);
    }
    reader.close();
    
    // 解析JSON响应并获取翻译结果
    JSONParser parser = new JSONParser();
    JSONObject json = (JSONObject) parser.parse(response.toString());
    JSONArray translations = (JSONArray) json.get("trans_result");
    JSONObject translation = (JSONObject) translations.get(0);
    String translatedText = (String) translation.get("dst");
    
    return translatedText;
} catch (Exception ex) {
    ex.printStackTrace();
    return null;
}

String chineseText = "你好世界";
String translatedText = translate(chineseText);

System.out.println(translatedText);
