OkHttp设置连接超时时间

private OkManager() {
        client = new OkHttpClient()
                .newBuilder()
                .connectTimeout(10, TimeUnit.SECONDS)//设置连接超时时间
                .readTimeout(20, TimeUnit.SECONDS)//设置读取超时时间
                .build();
        client.writeTimeoutMillis();
        gson = new Gson();
        handler = new Handler(Looper.getMainLooper());

        builder = new Request.Builder();

//        builder.header("Accept","application/json");
        builder.header("Accept-Encoding", "application/json");
        builder.header("Content-Type", "");


    }

处理异常

private void netWordFaild(Call call, IOException e) {
        if (e instanceof SocketTimeoutException) {//判断超时异常
            ToastUtils.showLong("Socket网络请求超时");
            return;
        }
        if (e instanceof ConnectException) {//判断连接异常，我这里是报Failed to connect to 10.7.5.144
            ToastUtils.showLong("网络请求超时");
            return;
        }
        ToastUtils.showLong("网络错误");


        Log.e(TAG, "网络错误" + e.toString());
    }
