方案2:捕获连接超时异常 [英] Retrofit 2: Catch connection timeout exception
本文介绍了方案2:捕获连接超时异常的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有以下设置:
final OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.setReadTimeout(5, TimeUnit.SECONDS);
okHttpClient.setConnectTimeout(5, TimeUnit.SECONDS);
RestAdapter.Builder builder = new RestAdapter.Builder()
.setEndpoint(ROOT)
.setClient(new OkClient(okHttpClient))
.setLogLevel(RestAdapter.LogLevel.FULL);
我正在尝试处理服务器故障并且用户收到连接超时异常的情况,这是我的日志记录:
I am trying to handle the situation in which my server is down and the user gets a connection timeout exception, this is my logging:
java.net.SocketTimeoutException: failed to connect to /192.168.0.53 (port 3000) after 5000ms
完整记录: http://pastebin.com/gscCGb7x
是否有办法将其路由到改造失败方法中,以便我可以在那里进行处理?
Is there a way to route this into the retrofit failure method so I can handle it over there?
提前谢谢!
推荐答案
用于翻新2
在您的Web服务实例中定义一个侦听器:
Define a listener in your web service instance:
public interface OnConnectionTimeoutListener {
void onConnectionTimeout();
}
将拦截器添加到您的Web服务:
Add an interceptor to your web service:
public WebServiceClient() {
OkHttpClient client = new OkHttpClient();
client.setConnectTimeout(10, TimeUnit.SECONDS);
client.setReadTimeout(30, TimeUnit.SECONDS);
client.interceptors().add(new Interceptor() {
@Override
public Response intercept(Chain chain) throws IOException {
return onOnIntercept(chain);
}
});
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.client(client)
.build();
webService = retrofit.create(WebService.class);
}
使用try-catch块将Intercep代码括起来,并在发生异常时通知监听器:
Enclose your intercep code with try-catch block and notify listener when exception happens:
private Response onOnIntercept(Chain chain) throws IOException {
try {
Response response = chain.proceed(chain.request());
String content = UtilityMethods.convertResponseToString(response);
Log.d(TAG, lastCalledMethodName + " - " + content);
return response.newBuilder().body(ResponseBody.create(response.body().contentType(), content)).build();
}
catch (SocketTimeoutException exception) {
exception.printStackTrace();
if(listener != null)
listener.onConnectionTimeout();
}
return chain.proceed(chain.request());
}
