org.apache.http的最佳替代品是什么？

因为他们在Android API差异报告中这样说。

Answer 1

你是对的DefaultHttpClient和AndroidHttpClient都弃用了这两个网络类。

现在，只有HttpUrlConnection类才会被用作替代它们。 Android开发者网站上的一些usage。

Answer 2

与Blackbelt一样，HttpURLConnection是HTTPClient的默认替代品。如果你感谢here（最后），你可能会发现他们将把资源集中在那里。

但是，值得一提的是，正在使用一些常见的API，并且如果您的应用的重点不是网页浏览，而是仅使用互联网来获取imgs，jsons，文本等，那么效果很好。

我建议Volley。看起来好像它会被支持很长时间（基于我的观点），并得到谷歌本身的支持。

Answer 3

经过3天的搜索和阅读HttpUrlConnection＆amp; CookieManager

我发现很多关于它的问题以及关于用它发送Cookies的更多问题

所以我为它做了一个完整的解决方案：

for Handle Cookies：

static CookieManager myCookies = new CookieManager(null, CookiePolicy.ACCEPT_ALL);

final public static void saveCookies(HttpURLConnection connection , Context context) {
Map<String, List<String>> headerFields = connection.getHeaderFields();

List<String> cookiesHeader = null;
try {
    cookiesHeader = headerFields.get("Set-Cookie");
} catch (Exception e) {
    e.printStackTrace();
}

if (cookiesHeader != null && myCookies != null) {
    for (String cookie : cookiesHeader) {
        try {
            cookie = cookie.replace("\"", "");
            myCookies.getCookieStore().add(connection.getURL().toURI(), HttpCookie.parse(cookie).get(0));
            String new_cookie = TextUtils.join(";", myCookies.getCookieStore().getCookies());

            PreferenceManager.getDefaultSharedPreferences(context).edit().putString("cookie", new_cookie).commit();

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }
}
}

final public static void loadCookies(HttpURLConnection connection , Context context) {
if (myCookies != null && myCookies.getCookieStore().getCookies().size() > 0) {
    connection.setRequestProperty("Cookie", TextUtils.join(";", myCookies.getCookieStore().getCookies()));
}
else {
    String new_cookie = PreferenceManager.getDefaultSharedPreferences(context).getString("cookie" , "");
    connection.setRequestProperty("Cookie", new_cookie );
}
}

对于使用Json数据的发布请求

  public String  URL_Connectin_Post ( String  endPoint , JSONObject data , Context context )
{
    URL url;
    try {
        url = new URL(baseUrl + endPoint);

        urlConnection = (HttpURLConnection) url.openConnection();
        loadCookies(urlConnection , context);
        urlConnection.setReadTimeout(15000);
        urlConnection.setConnectTimeout(15000);
        urlConnection.setDoInput(true);
        urlConnection.setDoOutput(true);

        /* optional request header */
        urlConnection.setRequestProperty("Content-Type", "application/json");
        urlConnection.setRequestProperty("charset", "UTF-8");
        urlConnection.addRequestProperty("Accept-Encoding", "UTF-8");

        /* optional request header  with UTF-8*/
        urlConnection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");

        /*  use this when you know data length  */
        urlConnection.setFixedLengthStreamingMode(data.toString().getBytes("UTF-8").length);

        /*  use this when you dont  know data length  */
  //      urlConnection.setChunkedStreamingMode(100);

        urlConnection.setUseCaches(true);
        urlConnection.setRequestMethod("POST");
        urlConnection.connect();

        OutputStream os = urlConnection.getOutputStream();
        BufferedWriter writer = new BufferedWriter( new OutputStreamWriter(os, "UTF-8"));
        writer.write(data.toString());
        writer.flush();
        writer.close();
        os.close();

        int responseCode=urlConnection.getResponseCode();
        if (responseCode == HttpsURLConnection.HTTP_OK)
        {
            InputStream in = urlConnection.getInputStream();
            saveCookies(urlConnection , context);
            Result = convertStreamToString(in);

        }

    } catch (Exception e) {
        e.printStackTrace();
    }

    return Result;
}

获取请求

    public  String URL_Connectin_Get(String  endPoint , Context context)
{
    URL url;
    try {
        url = new URL(baseUrl + endPoint);

        urlConnection = (HttpURLConnection) url.openConnection();
        loadCookies(urlConnection , context);

        urlConnection.setRequestProperty("Content-Type", "application/json");
        urlConnection.setRequestProperty("charset", "UTF-8");
        urlConnection.addRequestProperty("Accept-Encoding", "UTF-8");
        urlConnection.setDoInput(true);
        urlConnection.setRequestMethod("GET");
        urlConnection.connect();

        int responseCode=urlConnection.getResponseCode();
        if (responseCode == HttpsURLConnection.HTTP_OK) {

            InputStream in = urlConnection.getInputStream();
            if (urlConnection.getContentEncoding() != null && urlConnection.getContentEncoding().contains("gzip")) {
                GZIPInputStream inn = new GZIPInputStream(in);
                saveCookies(urlConnection , context);
            } else {
                saveCookies(urlConnection  , context);
            }
            Result = convertStreamToString(in);
        }

    } catch (IOException e) {
        e.printStackTrace();
    }

    return Result ;
}
