android 使用Okhttp封装上传JSON格式工具类
public class PostRequestJSON_Util { private static PostRequestJSON_Util postRequestJSONUtil; private Handler mHandler = new Handler(Looper.getMainLooper()); public static PostRequestJSON_Util getInstance() { if (postRequestJSONUtil == null) { postRequestJSONUtil = new PostRequestJSON_Util(); } return postRequestJSONUtil; } // map集合,需要上传的josn数据 public void postJson(String url, Map map, setResponseListener mListener) { String jsonStr = new Gson().toJson(map); RequestBody body = RequestBody.create(MediaType.parse("application/json;charset=utf-8"), jsonStr); OkHttpClient client = new OkHttpClient(); Request request = new Request.Builder() .url(url) .post(body) .build(); client.newCall(request).enqueue(new Callback() { @Override public void onFailure(Call call, IOException e) { if (mListener != null) { mHandler.post(new Runnable() { //使用handler切换到主线程更新UI @Override public void run() { try { mListener.onFailers(e.getMessage()); //接口回调失败方法 } catch (Exception e) { e.printStackTrace(); } } }); } } @Override public void onResponse(Call call, Response response) throws IOException { if (response.isSuccessful()) { if (mListener != null) { mHandler.post(new Runnable() { @Override public void run() { try { mListener.onSuccessful(response); //接口回调成功方法 } catch (Exception e) { e.printStackTrace(); } } }); } } } }); } public interface setResponseListener { void onSuccessful(Response response); void onFailers(String str); }} 使用如下：
// String URL = "https://api.test.ndmooc.com/v1/digitalmeet/add?token=9dbeb5da0d7372596e363a9383ea91aff855f18d"; String URL = API.apiurl() + "v1/digitalmeet/add?token=" + token; HashMap map = new HashMap<>(); map.put("mynotebooks_id", mynotebook_id); map.put("title", mTvMeetTitle.getText().toString()); if (mTvType.getText().toString().equals("会议")) { map.put("type", "1"); } else if (mTvType.getText().toString().equals("学习")) { map.put("type", "2"); } PostRequestJSON_Util.getInstance().postJson(URL, map, new PostRequestJSON_Util.setResponseListener() { @Override public void onSuccessful(Response response) { try { progressDialog.dismiss(); String string = response.body().string(); NewBuildBean buildBean = new Gson().fromJson(string, NewBuildBean.class); digitalmeet_id = buildBean.getData().getDigitalmeet_id(); startActivity(new Intent(NewBuildMeetActivity.this, MeetingMessageActivity.class).putExtra("digitalmeet_id", digitalmeet_id).putExtra("mynotebook_id", mynotebook_id).putExtra("notebook_id", notebook_id)); } catch (IOException e) { e.printStackTrace(); } } @Override public void onFailers(String str) { Log.i(TAG, "onFailers: " + str); } });
