如果我使用“ org.apache.http.legacy”並繼續使用諸如NameValuePair之類的已棄用的東西，還可以嗎？

Question

我正在嘗試將CCAvenue付款網關集成到我的android應用程序中。 為此，我下載了他們的集成套件並使用了它。 但是，這是該套裝目前進口org.apache.http並使用它的功能就像httppost，的NameValuePair等，所以，我的問題是，提到這里 ，是正常的，使下面提及的gradle這個變化，並繼續使用過時圖書館？

android {
    useLibrary 'org.apache.http.legacy'
}

將此代碼段放入ServiceHandler類中，您無需使用legacy。 您可以根據需要更改它們的代碼，這些只是示例。

/**
 *
 * @param postUrl
 * @param postParams
 * @return response in string
 */
public static String makeServiceCall(final String postUrl, final Map<String, String> postParams) {
    Log.e("URL#",postUrl);
    StringBuilder responseBuilder  = new StringBuilder();
    HttpURLConnection conn = null;
    try {
        final URL mUrl = new URL(postUrl);
        conn = (HttpURLConnection) mUrl.openConnection();
        conn.setDoInput(true);
        conn.setDoOutput(true);
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
        conn.setRequestProperty("charset", "utf-8");
        conn.setRequestProperty("User-Agent", "Mozilla/5.0 (Linux; U; Android-4.0.3; en-us; Galaxy Nexus Build/IML74K) AppleWebKit/535.7 (KHTML, like Gecko) CrMo/16.0.912.75 Mobile Safari/535.7");
        conn.connect();
        conn.setReadTimeout(180000);
        conn.setConnectTimeout(180000);
        final OutputStream os = conn.getOutputStream();
        BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));
        writer.write(getQuery(postParams));
        writer.flush();
        writer.close();
        os.close();
        final int responseCode = conn.getResponseCode();
        if (responseCode == HttpsURLConnection.HTTP_OK) {
            String line;
            BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            while ((line = br.readLine()) != null) {
                responseBuilder.append(line);
            }
        } else {
            responseBuilder.append("");
        }
    } catch (MalformedURLException e) {
        e.printStackTrace();
        responseBuilder.append(e.getMessage());
        return responseBuilder.toString();
    } catch (IOException e) {
        e.printStackTrace();
        responseBuilder.append(e.getMessage());
        return responseBuilder.toString();
    } finally {
        if (null != conn) {
            conn.disconnect();
        }
    }
    System.gc();
    return responseBuilder.toString();
}


/**
 * @Param: map , takes in value in key val format
 */
private static String getQuery(final Map<String, String> mPostItems) throws UnsupportedEncodingException {
    final StringBuilder result = new StringBuilder();
    boolean first = true;
    final Set<String> mKeys = mPostItems.keySet();
    for (String key : mKeys) {
        if (first)
            first = false;
        else
            result.append("&");

        result.append(URLEncoder.encode(key, "UTF-8"));
        result.append("=");
        result.append(URLEncoder.encode(mPostItems.get(key), "UTF-8"));
        Log.e("Key#",key+"#"+mPostItems.get(key));
    }
    return result.toString();
}
