android - 使用必应拼写检查 API 的空响应

Question

我想在 Android 应用程序中实现必应拼写检查 API。为了检查它是否起作用，我从 Microsoft 教程中复制了代码示例并将其改编为我的应用程序。看起来请求运行良好，根据响应，我的文本是正确的。但是文字不正确...有人知道这个问题或合适的解决方案吗？

如果我的代码有错误:

protected void requestWebService2(String key) throws IOException {
    final String host = "https://api.cognitive.microsoft.com";
    final String path = "/bing/v7.0/spellcheck";

    final String mkt = "en-US";
    final String mode = "proof";
    final String text = "Hollo, wrld!";

    thread = new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                URL url = new URL(host+path);
                HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
                connection.setRequestMethod("POST");
                connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
                connection.setRequestProperty("Ocp-Apim-Subscription-Key", key);
                connection.setDoOutput(true);

                String encoded_text = URLEncoder.encode (text, "UTF-8");
                String params = "?"+mkt+"&"+mode+"&"+"text="+encoded_text;

                DataOutputStream wr = new DataOutputStream(connection.getOutputStream());
                wr.writeBytes(params);
                wr.flush();
                wr.close();

                BufferedReader in = new BufferedReader(
                        new InputStreamReader(connection.getInputStream()));
                String line;
                while ((line = in.readLine()) != null) {
                    Log.i("...", line);
                }
                in.close();
            }catch (IOException e) {
                e.printStackTrace();
            }
        }
    });
    thread.start();
}

提前致谢!!!

所提供的代码示例中似乎存在一个小错误。您需要将 params 字符串修改为:

String params = "?mkt=" + mkt + "&" + "mode=" + mode + "&" + "text=" + encoded_text;

上面的代码中缺少

mkt 和 mode。
