Hello Mates,
1. In RequestConfig: What is the difference between ConnectTimeout and
ConnectionRequestTimeout ?
From quick look at code - I concluded that ConnectTimeout is "timeout when
client tries to connect to server" and ConnectionRequestTimeout is "timeout
when request can be considered expired".
2. How can I set connection manager timeout ? This time out implies if all
connections are busy/leased, it will wait for specified time in queue before
returning timeout error. Please correct if my understanding is wrong.
Previously I used httpparams to do that. But now httpparams seems to be have
deprecated.
// timeout waiting for a connection from the connection manager.
httpParams.setParameter("http.connection-manager.timeout", (int)
config.getConnectionManagerTimeout()
.toMillis());
3. How can I set HttpVersion ?
HttpProtocolParams.setVersion(httpParams, HttpVersion.HTTP_1_1);
4. Also I noticed that socket/connection timeouts are configured at multiple
places. Hence would like to make sure what is best practice to configure them.
Should we set at all below 3 places ?
1. IOReactorConfig has sockettimeout and connection timeout
2. SocketConfig which can be set to PoolingNHttpClientConnectionManager
3. RequestConfig - also has both Socket and Connection timeout setting.
Code:
PoolingNHttpClientConnectionManager connectionManager;
try {
DefaultConnectingIOReactor ioreactor = new DefaultConnectingIOReactor();
connectionManager = new PoolingNHttpClientConnectionManager(ioreactor);
} catch (IOReactorException e) {
throw new RuntimeException(e);
}
SocketConfig socketConfig = SocketConfig.custom().setSoTimeout((int)
config.getSocketTimeOut().toMillis()).setTcpNoDelay(true).build();
ConnectionConfig connectionConfig =
ConnectionConfig.custom().setCharset(Charset.forName("UTF-8")).build();
RequestConfig requestConfig =
RequestConfig.custom().setCircularRedirectsAllowed(true)
.setConnectTimeout((int) config.getConnectionTimeOut().toMillis())
.setConnectionRequestTimeout((int)
config.getConnectionTimeOut().toMillis())
.setSocketTimeout((int) config.getSocketTimeOut().toMillis())
.build();
connectionManager.setDefaultSocketConfig(socketConfig);
connectionManager.setDefaultConnectionConfig(connectionConfig);
HttpAsyncClientBuilder asyncHttpClientBuilder = HttpAsyncClientBuilder.create();
asyncHttpClientBuilder.setConnectionManager(connectionManager);
asyncHttpClientBuilder.setUserAgent("xyz");
asyncHttpClientBuilder.setDefaultRequestConfig(requestConfig);
HttpAsyncClient client = asyncHttpClientBuilder.build();
Thanks,
Jaikit
