![]() ![]() onStatus(HttpStatus::is4xxClientError, resp -> ", resp. Moreover, we can also add some logic according to the HTTP status: webClient.get() We can reuse any previously described exceptions and write our own handling methods using Reactor. doOnError(WriteTimeoutException.class, ex -> log.error("WriteTimeout")) onErrorReturn(SslHandshakeTimeoutException.class, new TextNode("SslHandshakeTimeout")) onErrorMap(ReadTimeoutException.class, ex -> new HttpTimeoutException("ReadTimeout")) Each type of timeout delivers a dedicated exception, so we can easily handle them using Ractive Streams and onError blocks : webClient.get() Now it's time to quickly talk about exception handling. We've just learned about different timeout configurations. The underlying Netty library delivers ReadTimeoutException and WriteTimeoutException classes accordingly to handle errors. For the first one, we provided a number with the TimeUnit specification, while the second converts the given number to seconds. The constructors for these handlers accept two variants of parameters. To configure timeouts we added ReadTimeOutHandlerand WriteTimeOutHandler instances. In this situation, we configured a connected callback via the doOnConnected() method, where we created additional handlers. ![]() addHandler(new WriteTimeoutHandler(10))) addHandler(new ReadTimeoutHandler(10, TimeUnit.SECONDS)) The HttpClient allows to configure additional handlers to configure those timeouts: HttpClient client = HttpClient.create() If your request contains a host name that requires resolution and you set Timeout to a value less than 15 seconds, it may take 15 seconds or more before a WebException is thrown to indicate a timeout on your request. When a request exceeds this timeout, a SocketException is thrown. This will apply to all requests made by the same client, after the timeout was set. When the connection is not established in a given time or dropped, a ConnectTimeoutException is thrown.Ī read timeout occurs when no data was read within a certain period of time, while the write timeout when a write operation cannot finish at a specific time. A Domain Name System (DNS) query may take up to 15 seconds to return or time out. Set a timeout on HttpClient You can also set a timeout on the HttpClient itself using nnectionTimeout. We also set the maximum number of probes before the connection dropping to 8. Asynchronous HTTP Client comes with an explicit idle timeout, on top of a TTL timeout. So, we've enabled keep-alive checks to probe after 5 minutes of being idle, at 60 seconds intervals. option(EpollChannelOption.TCP_KEEPCNT, 8) option(EpollChannelOption.TCP_KEEPINTVL, 60) option(EpollChannelOption.TCP_KEEPIDLE, 300) option(ChannelOption.SO_KEEPALIVE, true) Moreover, we can configure the keep-alive option, which will send TCP check probes when the connection is idle: HttpClient client = HttpClient.create() Netty sets that value to 30 seconds by default. The value provided is in milliseconds, so we configured the timeout for 10 seconds. option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 10000) We can use different channel options keys and the option() method to perform the configuration: HttpClient client = HttpClient.create() The timeout settings for the Boomi Atom Cloud are set to 10 minutes and cannot be changed. LastStacktrace = currentException.StackTrace ĬurrentException = currentException.InnerException Ĭ(writer.The connection timeout is a period within which a connection between a client and a server must be established. ![]() HttpClient client = new HttpClient() ", new string('\t', tabCount), currentException.Message) If you see that the HttpClient.Timeout property value is not being respected and the request is timing out prematurely, that should be a bug - please report that along with repro code to us. And the only timeout that should gate your request would be the HttpClient.Timeout value. Just to clarify further, if you never instantiate a WinHttpHandler object, but instead code directly to HttpClient and HttpClientHandler layers, the default values of the WinHttpHandler properties (SendTimeout, ReceiveHeadersTimeout, ReceiveDataTimeout) do not apply - they are all set to infinite under the covers. In keeping with this intention, we have more granular timeouts on that type since we have gotten developer requests in the past who asked for control over a specific stage of the request. The WinHttpHandler API is intended to provide a deeper control to developers for more advanced scenarios. , The HttpClient.Timeout property is intended to be exactly what you are referring to as the 99% case: an end-to-end timeout after which the request expires. ![]()
