okhttp拦截器的实现

public class LoggingInterceptor implements okhttp3.Interceptor {     public static String TAG = "LogInterceptor";    @Override    public Response intercept(Chain chain) throws IOException {        Request request = chain.request();        long startTime = System.currentTimeMillis();        Response response = chain.proceed(chain.request());        long endTime = System.currentTimeMillis();        long duration=endTime-startTime;        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(ResponseBody.create(mediaType, content))                .build();    }}
