android okhttp3的封裝

最近由於苦逼的學校課程,我們需要用android開發一款教學輔助軟體,所以我就開始看android開發的相關知識,今天實戰的時候發現okhttp還是蠻好用的,但是我不會對其進行封裝,於是乎就百度了一發,看了下別人的部落格,發現有位大佬寫的真的好用,就把複製過來,以備以後使用。

大佬部落格連結在此:

下面是程式碼:

public class HttpUtil {
    private static OkHttpClient client = null;

    private HttpUtil() {}

    public static OkHttpClient getInstance
() { if (client == null) { synchronized (HttpUtil.class) { if (client == null) client = new OkHttpClient(); } } return client; } /** * Get請求 * * @param url * @param callback */ public
static void doGet(String url, Callback callback) { Request request = new Request.Builder() .url(url) .build(); Call call = getInstance().newCall(request); call.enqueue(callback); } /** * Post請求傳送鍵值對資料 * * @param url * @param
mapParams * @param callback */
public static void doPost(String url, Map<String, String> mapParams, Callback callback) { FormBody.Builder builder = new FormBody.Builder(); for (String key : mapParams.keySet()) { builder.add(key, mapParams.get(key)); } Request request = new Request.Builder() .url(url) .post(builder.build()) .build(); Call call = getInstance().newCall(request); call.enqueue(callback); } /** * Post請求傳送JSON資料 * * @param url * @param jsonParams * @param callback */ public static void doPost(String url, String jsonParams, Callback callback) { RequestBody body = RequestBody.create(MediaType.parse("application/json; charset=utf-8") , jsonParams); Request request = new Request.Builder() .url(url) .post(body) .build(); Call call = getInstance().newCall(request); call.enqueue(callback); } }
