OkHttp简介类

Log日志拦截器

OkHttpClient okHttpClient = new OkHttpClient.Builder()
        .addInterceptor(new LoggingInterceptor())//日志拦截器
        .connectTimeout(10, TimeUnit.SECONDS)//连接超时
        .readTimeout(10,TimeUnit.SECONDS)//读取超时
        .writeTimeout(10,TimeUnit.SECONDS)//写入超时
        .build();
