添加 retrfiot 拦截器Interceptor ，打印服务器返回的json并添加网络请求公共的header

import java.io.IOException; import java.nio.charset.Charset; import okhttp3.Interceptor; import okhttp3.Request; import okhttp3.Response; import okhttp3.ResponseBody; import okio.Buffer; import okio.BufferedSource; /** * 网络切面处理 * Created By: AndroidStudio * Author :http://write.blog.csdn.net/postedit/53446562 * */ public class OkHttpLoggingInterceptor implements Interceptor { @Override public Response intercept(Chain chain) throws IOException { Request.Builder newBuilder = chain .request() .newBuilder(); Request request = newBuilder .addHeader("Content-Type","application/json; charset=utf-8") .addHeader("Authorization", Bearer ) .build(); String cacheControl=request.cacheControl().toString(); if(TextUtils.isEmpty(cacheControl)){ cacheControl = "public, max-age=60"; } Response response = chain.proceed(request); if(BaseApplication.getInstance().isdebug){ Log.e("ssss", "response返回参数" + response.toString()); //添加打印服务器返回的数据 ResponseBody responseBody = response.body(); long contentLength = responseBody.contentLength(); BufferedSource source = responseBody.source(); source.request(Integer.MAX_VALUE); // Buffer the entire body. Buffer buffer = source.buffer(); if (contentLength != 0) { Log.e("服务器返回数据：", ""+buffer.clone().readString(Charset.forName("UTF-8"))); } } return response. newBuilder() .header("Cache-Control", cacheControl) .build(); } }
