retrofit2设置超时,Retrofit2 SocketTimeOutException

I setup for Retrofit:

private Interceptor interceptor = new Interceptor() {

@Override

public Response intercept(Chain chain) throws IOException {

Request request = chain.request();

if (!NetworkUtil.isNetworkAvailable()) {

request = request.newBuilder()

.cacheControl(CacheControl.FORCE_CACHE)

.build();

}

Response response = chain.proceed(request); //Exception here

if (NetworkUtil.isNetworkAvailable()) {

String cacheControl = request.cacheControl().toString();

response = response.newBuilder()

.removeHeader(“Pragma”)

.removeHeader(“Cache-Control”)

.header(“Cache-Control”, cacheControl)

.build();

} else {

int maxStale = 60 * 60 * 24 * 7;

response = response.newBuilder()

.removeHeader(“Pragma”)

.removeHeader(“Cache-Control”)

.header(“Cache-Control”, “public, only-if-cached, max-stale=” + maxStale)

.build();

}

return response;

}

};

And I use to setup cache:

builder = new OkHttpClient.Builder()

.cookieJar(new PersistentCookieJar(new SetCookieCache(), new SharedPrefsCookiePersistor(Apploader.context)))

.addNetworkInterceptor(interceptor)

.addInterceptor(interceptor)

.cache(cache)

.connectTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);

Sometime when server response too long My Application crash because SocketTimeOut

It break on line: Response response = chain.proceed(request); as I comment.

SocketTimeOut is subclass of IOException, why my code can’t catch it.

How do I resolved this problem.

解决方案

Use OkHttpClient for more configurations, like follwing :

final OkHttpClient okHttpClient = new OkHttpClient.Builder()

.connectTimeout(20, TimeUnit.SECONDS)

.writeTimeout(20, TimeUnit.SECONDS)

.readTimeout(30, TimeUnit.SECONDS)

.build();

and then set this okHttpClient with RetrofitBuilder,

Retrofit.Builder()

.client(okHttpClient);
