Android API 23已删除软件包

就像Blackbelt所言，HttpURLConnection是HTTPClient的默认替代品。 如果你在这里 （最后）喋喋不休，你可能会看到那些他们将在哪里集中资源。

不过，值得一提的是，一些常用的API正在被使用，如果你的应用程序的焦点不是网页浏览，而只是使用互联网来获取imgs，jsons，文本等等，那么它可以很好地工作。

我推荐Volley 。 它看起来会支持很长时间（根据我的意见），并支持谷歌本身。

如果您正在更新您的项目，并且您希望继续使用Apache HTTP API，则必须在build.gradle文件中声明以下内容：（ 更多信息 ，请参见此处 ）

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

注意你使用的gradle版本，我在我的gradle-wrapper.properties上使用2.6

 distributionUrl=https\://services.gradle.org/distributions/gradle-2.6-all.zip 

你是正确的DefaultHttpClient和AndroidHttpClient这两个网络类都被弃用。

现在，只有HttpUrlConnection是一个类将被用来替代它们。 Android开发者网站上的一些用法 。

经过3天的浏览和阅读有关HttpUrlConnection＆CookieManager

我发现很多关于它的问题以及关于使用它发送Cookie的更多问题

所以我为它做了一个完整的解决方案：

处理曲奇：

 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 ); } } 

用于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 ; }
