okhttp封装+拦截器+异常捕获类

首先添加okhttp的封装类

import android.os.Handler;
import android.os.Looper;

import com.bwie.moni.LogInterceptor;

import java.io.IOException;
import java.util.Map;
import java.util.concurrent.TimeUnit;

import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.FormBody;
import okhttp3.MediaType;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;


public class HttpUtils {

    private OkHttpClient.Builder client;
    //超时时间
    public static final int TIMEOUT=1000*60;

    //json请求
    public static final MediaType JSON = MediaType
            .parse("application/json; charset=utf-8");

    private Handler handler = new Handler(Looper.getMainLooper());

    public HttpUtils() {
        this.init();
    }

    private void init() {

        client=  new OkHttpClient.Builder().addInterceptor(new LogInterceptor());
        //设置超时
        client.connectTimeout(TIMEOUT, TimeUnit.SECONDS).
                writeTimeout(TIMEOUT,TimeUnit.SECONDS).readTimeout(TIMEOUT, TimeUnit.SECONDS)
                .build();
    }

    /**
     * post请求  json数据为body
     *
     */
    public void postJson(String url,String json,final HttpCallBack callBack){
        RequestBody body = RequestBody.create(JSON,json);
        final Request request = new Request.Builder().url(url).post(body).build();

        OnStart(callBack);

        client.build().newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                OnError(callBack, e.getMessage());
            }
            @Override
            public void onResponse(Call call, Response response) throws IOException {
                if (response.isSuccessful()) {
                    onSuccess(callBack, response.body().string());
                } else {
                    OnError(callBack, response.message());
                }
            }
        });
    }
    /**
     * post请求  map是body
     *
     * @param url
     * @param map
     * @param callBack
     */
    public void postMap(String url,Map map,final HttpCallBack callBack){
        FormBody.Builder builder=new FormBody.Builder();

        //遍历map
        if(map!=null){
            for (Map.Entry entry : map.entrySet()){
                builder.add(entry.getKey(), entry.getValue().toString());
            }
        }
        RequestBody body = builder.build();
        Request request = new Request.Builder().url(url).post(body).build();
        OnStart(callBack);
        client.build().newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                OnError(callBack,e.getMessage());
            }
            @Override
            public void onResponse(Call call, Response response) throws IOException {
                if(response.isSuccessful()){
                    onSuccess(callBack,response.body().string());
                }else{
                    OnError(callBack, response.message());
                }
            }
        });
    }
    /**
     * get 请求
     *
     * @param url
     * @param callBack
     */
    public void getJson(String url,final HttpCallBack callBack){
        Request request = new Request.Builder().url(url).build();
        OnStart(callBack);
        client.build().newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                OnError(callBack,e.getMessage());
            }
            @Override
            public void onResponse(Call call, Response response) throws IOException {
                if (response.isSuccessful()){
                    onSuccess(callBack,response.body().string());
                }else{
                    OnError(callBack,response.message());
                }
            }
        });
    }
    public void OnStart(HttpCallBack callBack){
        if(callBack!=null){
            callBack.onstart();
        }
    }
    public void onSuccess(final HttpCallBack callBack,final String data){
        if(callBack!=null){
            handler.post(new Runnable() {
                @Override
                public void run() {//在主线程操作
                    callBack.onSusscess(data);
                }
            });
        }
    }
    public void OnError(final HttpCallBack callBack,final String msg){
        if(callBack!=null){
            handler.post(new Runnable() {
                @Override
                public void run() {
                    callBack.onError(msg);
                }
            });
        }
    }
    public static abstract class HttpCallBack{
        //开始
        public void onstart(){};
        //成功回调
        public abstract void onSusscess(String data);
        //失败
        public void onError(String meg){};
    }
}

添加拦截器

这是一个类，创建一下

import android.util.Log;

import java.io.IOException;

import okhttp3.FormBody;
import okhttp3.Interceptor;
import okhttp3.Request;

public class LogInterceptor implements Interceptor {

    public static String TAG = "LogInterceptor";

    @Override
    public okhttp3.Response intercept(Chain chain) throws IOException {
        Request request = chain.request();
        long startTime = System.currentTimeMillis();
        okhttp3.Response response = chain.proceed(chain.request());
        long endTime = System.currentTimeMillis();
        long duration=endTime-startTime;
        okhttp3.MediaType mediaType = response.body().contentType();
        String content = response.body().string();
        Log.d(TAG,"\n");
        Log.d(TAG,"----------Start----------------");
        Log.d(TAG, "| "+request.toString());
        String method=request.method();
        if("POST".equals(method)){
            StringBuilder sb = new StringBuilder();
            if (request.body() instanceof FormBody) {
                FormBody body = (FormBody) request.body();
                for (int i = 0; i < body.size(); i++) {
                    sb.append(body.encodedName(i) + "=" + body.encodedValue(i) + ",");
                }
                sb.delete(sb.length() - 1, sb.length());
                Log.d(TAG, "| RequestParams:{"+sb.toString()+"}");
            }
        }
        Log.d(TAG, "| Response:" + content);
        Log.d(TAG,"----------End:"+duration+"毫秒----------");
        return response.newBuilder()
                .body(okhttp3.ResponseBody.create(mediaType, content))
                .build();
    }
}

添加异常捕获类 

在初始化app中写

CrashHandler crashHandler = CrashHandler.getInstance();
crashHandler.init(getApplicationContext());

import java.io.File; import java.io.FileOutputStream; import java.io.PrintWriter; import java.io.StringWriter; import java.io.Writer; import java.lang.Thread.UncaughtExceptionHandler; import java.lang.reflect.Field; import java.text.DateFormat; import java.text.SimpleDateFormat; import java.util.Date; import java.util.HashMap; import java.util.Map; import android.content.Context; import android.content.pm.PackageInfo; import android.content.pm.PackageManager; import android.content.pm.PackageManager.NameNotFoundException; import android.os.Build; import android.os.Environment; import android.os.Looper; import android.util.Log; import android.widget.Toast; /** * UncaughtException处理类,当程序发生Uncaught异常的时候,有该类来接管程序,并记录发送错误报告. * * @author user * */ public class CrashHandler implements UncaughtExceptionHandler { public static final String TAG = "CrashHandler"; //系统默认的UncaughtException处理类 private Thread.UncaughtExceptionHandler mDefaultHandler; //CrashHandler实例 private static CrashHandler INSTANCE = new CrashHandler(); //程序的Context对象 private Context mContext; //用来存储设备信息和异常信息 private Map infos = new HashMap(); //用于格式化日期,作为日志文件名的一部分 private DateFormat formatter = new SimpleDateFormat( "yyyy-MM-dd-HH-mm-ss"); /** 保证只有一个CrashHandler实例 */ private CrashHandler() { } /** 获取CrashHandler实例 ,单例模式 */ public static CrashHandler getInstance() { return INSTANCE; } /** * 初始化 * * @param context */ public void init(Context context) { mContext = context; //获取系统默认的UncaughtException处理器 mDefaultHandler = Thread. getDefaultUncaughtExceptionHandler(); //设置该CrashHandler为程序的默认处理器 Thread. setDefaultUncaughtExceptionHandler( this); } /** * 当UncaughtException发生时会转入该函数来处理 */ @Override public void uncaughtException(Thread thread, Throwable ex) { if (!handleException(ex) && mDefaultHandler != null) { //如果用户没有处理则让系统默认的异常处理器来处理 mDefaultHandler.uncaughtException(thread, ex); } else { try { Thread. sleep( 3000); } catch (InterruptedException e) { Log. e( TAG, "error : ", e); } //退出程序 android.os.Process. killProcess(android.os.Process. myPid()); System. exit( 1); } } /** * 自定义错误处理,收集错误信息 发送错误报告等操作均在此完成. * * @param ex * @return true:如果处理了该异常信息;否则返回false. */ private boolean handleException(Throwable ex) { if (ex == null) { return false; } //使用Toast来显示异常信息 new Thread() { @Override public void run() { Looper. prepare(); Toast. makeText( mContext, "很抱歉,程序出现异常,即将退出.", Toast. LENGTH_LONG).show(); Looper. loop(); } }.start(); //收集设备参数信息 collectDeviceInfo( mContext); //保存日志文件 saveCrashInfo2File(ex); return true; } /** * 收集设备参数信息 * @param ctx */ public void collectDeviceInfo(Context ctx) { try { PackageManager pm = ctx.getPackageManager(); PackageInfo pi = pm.getPackageInfo(ctx.getPackageName(), PackageManager. GET_ACTIVITIES); if (pi != null) { String versionName = pi. versionName == null ? "null" : pi. versionName; String versionCode = pi. versionCode + ""; infos.put( "versionName", versionName); infos.put( "versionCode", versionCode); } } catch (NameNotFoundException e) { Log. e( TAG, "an error occured when collect package info", e); } Field[] fields = Build. class.getDeclaredFields(); for (Field field : fields) { try { field.setAccessible( true); infos.put(field.getName(), field.get( null).toString()); Log. d( TAG, field.getName() + " : " + field.get( null)); } catch (Exception e) { Log. e( TAG, "an error occured when collect crash info", e); } } } /** * 保存错误信息到文件中 * * @param ex * @return 返回文件名称,便于将文件传送到服务器 */ private String saveCrashInfo2File(Throwable ex) { StringBuffer sb = new StringBuffer(); for (Map.Entry entry : infos.entrySet()) { String key = entry.getKey(); String value = entry.getValue(); sb.append(key + "=" + value + " \n "); } Writer writer = new StringWriter(); PrintWriter printWriter = new PrintWriter(writer); ex.printStackTrace(printWriter); Throwable cause = ex.getCause(); while (cause != null) { cause.printStackTrace(printWriter); cause = cause.getCause(); } printWriter.close(); String result = writer.toString(); sb.append(result); try { long timestamp = System. currentTimeMillis(); String time = formatter.format( new Date()); String fileName = "crash-" + time + "-" + timestamp + ".log"; if (Environment. getExternalStorageState().equals(Environment. MEDIA_MOUNTED)) { //String path = "/sdcard/crash/"; //String path = Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)+"/crash/"; String path = "mnt/sdcard/***/"; File dir = new File(path); if (!dir.exists()) { dir.mkdirs(); } FileOutputStream fos = new FileOutputStream(path + fileName); fos.write(sb.toString().getBytes()); fos.close(); } return fileName; } catch (Exception e) { Log. e( TAG, "an error occured while writing file...", e); } return null; }}
