okhttp設定連結超時網上有很多，記錄一下

非同步

OkHttpClient client = new OkHttpClient.Builder()
        .connectTimeout(10, TimeUnit.SECONDS)//設定連線超時時間
.readTimeout(20, TimeUnit.SECONDS)//設定讀取超時時間
.build();
Request.Builder builder = new Request.Builder().url("http://10.7.5.144/oos");
Call call = client.newCall(builder.build());
 
call.enqueue(new Callback() {
    @Override
public void onFailure(Call call, IOException e) {
        if(e instanceof SocketTimeoutException){//判斷超時異常
}
        if(e instanceof ConnectException){//判斷連線異常，我這裡是報Failed to connect to 10.7.5.144
}
    }

    @Override
public void onResponse(Call call, Response response) throws 
 
IOException {

    }
});
