1.请求工具类
package .myapplication.http.base;import android.os.Handler;import android.os.Message;import android.support.annotation.NonNull;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.io.OutputStreamWriter;import .HttpURLConnection;import .URL;import .dev.utils.L;/*** CreateTime /9/24 09:28* Author LiuShiHua* Description：*/public class BaseRequest {private static final int REQUEST_TIMEOUT = 60 * 1000;//设置超时60秒public static final int HAND_REQUEST_SUCCESS = 300;public static final int HAND_REQUEST_FAILURE = 400;/*** post请求** @param reqUrl* @param jsonParam json对象的String参数* @param handler 返回数据接收handler* @param type返回请求类型*/public static void postJsonData(final String reqUrl, final String jsonParam, @NonNull final Handler handler, final int type) {if (reqUrl == null) return;L.d("postJsonData请求地址：" + reqUrl);L.d("postJsonData请求参数：" + jsonParam);new Thread() {@Overridepublic void run() {super.run();BufferedReader reader = null;try {URL url = new URL(reqUrl);// 创建连接HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setDoOutput(true);connection.setConnectTimeout(REQUEST_TIMEOUT);connection.setDoInput(true);connection.setUseCaches(false);connection.setInstanceFollowRedirects(true);connection.setRequestMethod("POST"); // 设置请求方式connection.setRequestProperty("Content-Type", "application/json"); // 设置发送数据的格式//设置发送数据长度（用于发送大量数据使用）connection.setRequestProperty("Content-Length", String.valueOf(jsonParam.length()));//一定要用BufferedReader 来接收响应， 使用字节来接收响应的方法是接收不到内容的OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream(), "UTF-8"); // utf-8编码out.append(jsonParam);out.flush();out.close();L.d(String.valueOf(connection.getResponseCode()));if (connection.getResponseCode() == HttpURLConnection.HTTP_OK) {// 读取响应reader = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8"));String line;String res = "";while ((line = reader.readLine()) != null) {res += line;}L.d(res);reader.close();//通过handler来回传返回数据Message msg = new Message();msg.obj = res;msg.arg1 = HAND_REQUEST_SUCCESS;msg.what = type;handler.sendMessage(msg);} else {Message msg = new Message();msg.obj = "请求错误," + connection.getResponseCode();msg.arg1 = HAND_REQUEST_FAILURE;msg.what = type;handler.sendMessage(msg);}} catch (IOException e) {e.printStackTrace();Message msg = new Message();msg.obj = "请求异常,请检查网络";msg.arg1 = HAND_REQUEST_FAILURE;msg.what = type;handler.sendMessage(msg);L.e("POST IOException", e);}}}.start();}public static void getData(final String getUrl, final Handler handler, final int type) {L.d("getData请求地址：" + getUrl);new Thread() {@Overridepublic void run() {super.run();String acceptData = "";try {URL url = new URL(getUrl);// 创建连接HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setConnectTimeout(REQUEST_TIMEOUT);connection.setRequestMethod("GET"); // 设置请求方式connection.connect();L.d(String.valueOf(connection.getResponseCode()));if (connection.getResponseCode() == HttpURLConnection.HTTP_OK) {// Log.i("接受到的数据：", String.valueOf(connection.getResponseCode()));InputStream inputStream = connection.getInputStream();BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "utf-8"));String line;while ((line = bufferedReader.readLine()) != null) { //不为空进行操作acceptData += line;}L.d(acceptData);if (handler != null) {Message msg = new Message();msg.obj = acceptData;msg.arg1 = HAND_REQUEST_SUCCESS;msg.what = type;handler.sendMessage(msg);}} else {Message msg = new Message();msg.obj = "请求错误," + connection.getResponseCode();msg.arg1 = HAND_REQUEST_FAILURE;msg.what = type;handler.sendMessage(msg);}} catch (IOException e) {e.printStackTrace();Message msg = new Message();msg.obj = "请求异常,请检查网络";msg.arg1 = HAND_REQUEST_FAILURE;msg.what = type;handler.sendMessage(msg);L.e("GET IOException", e);}}}.start();}}
2.调用（传入handler来接收返回值 我这里没传）
Map<String, Object> params = new HashMap<>();params.put("deviceAlarmType", 35);params.put("sn", "SN-IFMJVGSCOF4LSK7T-del");OldRequetsUtils.postJsonData(new Gson().toJson(params), handler,1);
日志效果：
OldRequetsUtils: {“code”:0,“message”:“操作成功”,“obj”:{},“tokenStr”:""}
