1.未封装的Okhttp
private OkHttpClient client = new OkHttpClient();
FormEncodingBuilder builder = new FormEncodingBuilder(); builder.add("accountName",user); builder.add("password",password); Request request = new Request.Builder() .url("www.baidu.com") .post(builder.build()) .build(); client.newCall(request).enqueue(new com.squareup.okhttp.Callback() { @Override public void onFailure(Request request, IOException e) { } @Override public void onResponse(Response response) throws IOException { // Log.e("response",response.body().string()); ParseJson(response.body().string()); } });
以上就是简单的okhttp网络请求
2.封装好的网络请求:
package atmosphere.hanwei.com.util; import android.os.Handler; import android.os.Looper; import android.util.Log; import com.squareup.okhttp.Callback; import com.squareup.okhttp.FormEncodingBuilder; import com.squareup.okhttp.OkHttpClient; import com.squareup.okhttp.Request; import com.squareup.okhttp.RequestBody; import com.squareup.okhttp.Response; import java.io.IOException; import java.net.CookieManager; import java.net.CookiePolicy; import java.util.List; import java.util.concurrent.TimeUnit; /** * 二次封装好的okhttp(其他类中直接调用) * Created by cmh on 2017/1/3. */ public class OkHttpUtils { private static final String TAG = "OkHttpUtils"; private static OkHttpUtils mInstance; private OkHttpClient mOkHttpClient; private Handler mHandler; private OkHttpUtils() { /** * 构建OkHttpClient */ mOkHttpClient = new OkHttpClient(); /** * 设置连接的超时时间 */ mOkHttpClient.setConnectTimeout(10, TimeUnit.SECONDS); /** * 设置响应的超时时间 */ mOkHttpClient.setWriteTimeout(10, TimeUnit.SECONDS); /** * 请求的超时时间 */ mOkHttpClient.setReadTimeout(30, TimeUnit.SECONDS); /** * 允许使用Cookie */ mOkHttpClient.setCookieHandler(new CookieManager(null, CookiePolicy.ACCEPT_ORIGINAL_SERVER)); /** * 获取主线程的handler */ mHandler = new Handler(Looper.getMainLooper()); } /** * 通过单例模式构造对象 * @return OkHttpUtils */ private synchronized static OkHttpUtils getmInstance() { if (mInstance == null) { mInstance = new OkHttpUtils(); } return mInstance; } /** * 构造Get请求 * @param url 请求的url * @param callback 结果回调的方法 */ private void getRequest(String url, final ResultCallback callback) { final Request request = new Request.Builder().url(url).build(); deliveryResult(callback, request); } /** * 构造post 请求 * @param url 请求的url * @param callback 结果回调的方法 * @param params 请求参数 */ private void postRequest(String url, final ResultCallback callback, List<Param> params) { Request request = buildPostRequest(url, params); deliveryResult(callback, request); } /** * 处理请求结果的回调 * @param callback * @param request */ private void deliveryResult(final ResultCallback callback, Request request) { mOkHttpClient.newCall(request).enqueue(new Callback() { @Override public void onFailure(Request request, final IOException e) { sendFailCallback(callback, e); } @Override public void onResponse(Response response) throws IOException { try { String str = response.body().string(); sendSuccessCallBack(callback, str); } catch (final Exception e) { Log.e(TAG, "convert json failure", e); sendFailCallback(callback, e); } } }); } /** * 发送失败的回调 * @param callback * @param e */ private void sendFailCallback(final ResultCallback callback, final Exception e) { mHandler.post(new Runnable() { @Override public void run() { if (callback != null) { callback.onFailure(e); } } }); } /** * 发送成功的调 * @param callback * @param obj */ private void sendSuccessCallBack(final ResultCallback callback, final Object obj) { mHandler.post(new Runnable() { @Override public void run() { if (callback != null) { callback.onSuccess(obj); } } }); } /** * 构造post请求 * @param url 请求url * @param params 请求的参数 * @return 返回 Request */ private Request buildPostRequest(String url, List<Param> params) { FormEncodingBuilder builder = new FormEncodingBuilder(); for (Param param : params) { builder.add(param.key, param.value); } RequestBody requestBody = builder.build(); return new Request.Builder().url(url).post(requestBody).build(); } /**********************对外接口************************/ /** * get请求 * @param url 请求url * @param callback 请求回调 */ public static void get(String url, ResultCallback callback) { getmInstance().getRequest(url, callback); } /** * post请求 * @param url 请求url * @param callback 请求回调 * @param params 请求参数 */ public static void post(String url, final ResultCallback callback, List<Param> params) { getmInstance().postRequest(url, callback, params); } /** * http请求回调类,回调方法在UI线程中执行 * @param <T> */ public static abstract class ResultCallback<T> { public ResultCallback(){ } /** * 请求成功回调 * @param response */ public abstract void onSuccess(T response); /** * 请求失败回调 * @param e */ public abstract void onFailure(Exception e); } /** * post请求参数类 */ public static class Param { String key;//请求的参数 String value;//参数的值 public Param() { } public Param(String key, String value) { this.key = key; this.value = value; } } }
post:
List<OkHttpUtils.Param> list = new ArrayList<OkHttpUtils.Param>(); list.add(new OkHttpUtils.Param("accountName",user)); list.add(new OkHttpUtils.Param("password",password)); OkHttpUtils.post("www.baidu.com", new OkHttpUtils.ResultCallback<String>() { @Override public void onSuccess(String response) { ParseJson(response); } @Override public void onFailure(Exception e) { } },list);
get:
OkHttpUtils.post("www.baidu.com", new OkHttpUtils.ResultCallback<String>() { @Override public void onSuccess(String response) { ParseJson(response); } @Override public void onFailure(Exception e) { } });
