OKhttp的简单封装加拦截器

1.拦截器
package com.example.utils;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 {        //有些服务器连接不能获取返回的数据需要加一个请求头        //  Request request = chain.request().newBuilder().addHeader("User-Agent","OkHttp Example").build();        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();    }}


2.okhttp封装及添加拦截器

               }            }        }        return okHttpManager;    }    private boolean setRequest=false;    private boolean setOkHttpClient=false;    public OkHttpManager setRequest(Request request) {        this.request = request;

           }            okHttpClient.newCall(request).enqueue(new Callback() {                @Override                public void onFailure(Call call, IOException e) {                    mcallBack.onFailure(call,e);
