Okhttp3 onFailure检测
我输入OKHTTP（OKHTTP3）以从服务器检索数据。如果从服务器检索信息的过程以“ onfailure”结尾，我想澄清为什么该过程以“ onfailure”结束。我如何确定域是否与服务器断开（服务器为下降，域没有服务器）或用户的Internet打开？在启动OKHTTP3之前，如何在onfailure上进行此操作，而不是在互联网上检查Internet，然后启动OKHTTP3进程？我想相应地发出相应的敬酒消息。
onfailure：
client.newCall(request).enqueue(new Callback () {
@Override
public void onFailure (Call call, IOException e) {
e.printStackTrace ();
}
如何：
- 互联网不起作用
- 域问题
- 。 我可以诊断onfailure中的问题并显示相应的对话框？
I entered Okhttp (okhttp3) to retrieve data from the server. If the process of retrieving information from the server ends with "onFailure", I want to clarify why the process ends with "onFailure". How can I find out if the domain is disconnected from the server (the server is down‚ the domain is without a server) or the user's Internet is on? How can I do this on onFailure instead of checking the internet before starting okhttp3 and then starting the okhttp3 process? I want to issue a corresponding Toast message accordingly.
onFailure:
client.newCall(request).enqueue(new Callback () {
@Override
public void onFailure (Call call, IOException e) {
e.printStackTrace ();
}
how to:
- The internet doesn't work
- Domain problem
- other...
Can I diagnose problems in onFailure and show a corresponding dialog?
